Chapter 1 Overview of the TimeProvider

Overview

Overview

The TimeProvider is Synchronization Supply Unit (SSU) designed specifically to meet the needs at the network edge. In small offices where core office synchronization solutions are critical, an edge clock like the TimeProvider is ideal because of its compact size and flexibility. Using the integrated GPS features, the

TimeProvider can be used in a “small” Central Office to act as a Primary Reference

Source (PRS).

The TimeProvider’s unique design incorporates the input, output, and clock functions in a single card, available with either a Rubidium or quartz oscillator. This allows you to simplify the storage inventory required for future expansion needs.

The TimeProvider shelf requires only three plug-in cards to operate with full redundancy: dual Input/Output/Clock cards (IOCs) and a single Information

Management Card (IMC), which serves as a communications/alarm interface. The main shelf provides up to 32 redundant universal timing outputs; an optional

Expansion Panel provides an additional 32 redundant outputs.

Using Symmetricom’s SmartClock™ technology design, the oscillators within the

IOCs are enhanced with improved performance and accuracy. Using intelligent firmware algorithms, SmartClock “learns” the effects of the ageing of the clock while it is locked to a reference signal and stores this information in its memory. If the reference signals are lost or disqualified, SmartClock uses the stored data to compensate for frequency changes while the TimeProvider continues to distribute highly stable synchronization signals.

The TimeProvider also uses Symmetricom’s BesTime

®

algorithm when the GPS input is activated. By using other inputs as references, Bestime calculates and determines a weighting factor for each of the inputs and ensembles them in the overall timing scheme to provide very accurate timing outputs. In the event of GPS signal loss, BesTime continues to predict GPS timing information to provide reliable system timing outputs and holdover performance, ensuring that system reliability is

maintained. See BesTime , on page 39 for more information.

New Capabilities

The operating software in the TimeProvider is improved to provide the following capabilities:

Retiming – A new Output module is available to re-time, re-amplify, and re-shape an inbound (East) data-bearing signal. The TimeProvider provides a stable frequency source to re-transmit the data to the line-terminating Network Element.

The return (West) path on the module provides re-amplify and re-shape only. See

Retimer Module , on page 30, for more information.

Input/output port labeling – The user can label TimeProvider input and output ports, including the input side on the Retimer module. The label, or circuit ID, can be up to 40 characters long.

TimeProvider User’s Guide 097-58001-02 Revision C – August 2005

Chapter 1 Overview of the TimeProvider

Overview

Event log management – Event log retrieval has been enhanced to provide a more user-programmable lookup. In the new format, there are two additional methods to retrieve the event log. 1) The user can specify a beginning point (the

“index”) within the event log and display a number of events (“count” value) starting from the index. 2) The user can display events within a specified “start date” and “stop date.”

When you use redundant IOC cards, Symmetricom recommends that you use the same revision of firmware for proper operation.

Shelves

The TimeProvider is available in two shelf models. Each shelf supports up to 32 redundant output channels.

The TimeProvider 1000 is a 175 mm tall ETSI shelf that meets the requirements

of ETSI 300 119-4 January 1994. Figure 1-1

shows the TimeProvider 1000 shelf.

The TimeProvider 1100 is a 130 mm tall rear-access shelf; indicators are on the front panel and connections are available on the rear panel.

TimeProvider User’s Guide 097-58001-02 Revision C – August 2005

Chapter 1 Overview of the TimeProvider

Overview

The TimeProvider qualifies the input reference signals and detect the following errors: Loss of Signal (LOS), Alarm Indication Signal (AIS), Loss of Framing, and

Synchronization Status Messages (SSM) where applicable.

Reference Input

Signals , on page 32, describes the inputs in more detail.

Outputs

The TimeProvider produces a variety of outputs to meet different signal standards.

Output signal types include 8 kHz, 1.544 MHz, 2.048 MHz, 6.312 MHz, E1, T1, CC,

JCC, and JCC4. A Retiming module is also available to re-time, re-shape, and re-amplify E1 and T1 signals. The E1 and T1 signals can be provisioned with standard framing that meets G.703 formats. These outputs are available through one of several different connector panels. The E1 Retiming module is available with either BNC or Siemens 1.6/5.6 connectors, and the T1 Retiming module has

wirewrap connectors. See Output Signals , on page 36, for more information on

output signals.

The TimeProvider outputs are arranged into four groups of eight outputs per group in the Main shelf and four groups of eight outputs per group in the optional

Expansion panel. Each group is labeled A, B, C, and D, and can be configured independently.

Communication

Three communications ports provide access to the TimeProvider: Ethernet, local

Craft serial port, and a Remote serial port. These ports are described in detail in

Communication Ports , on page 31.

Clocks

The TimeProvider’s clock design includes a highly stable ovenized Quartz crystal or

Rubidium oscillator with Direct Digital Synthesis (DDS) to produce accurate synchronization outputs. In a dual-IOC configuration, the clock function is redundant to provide protection. Each IOC qualifies the input signal and filters jitter and wander noise elements that may exist. In the event that all input references are lost or disqualified, the TimeProvider’s clock design, together with the SmartClock technology, goes into holdover mode with the oscillator providing the system reference.

The Rubidium IOC meets Stratum 2/Type II performance; the Quartz IOC meets

Stratum 3E/Type I performance.

Chapter 1 Overview of the TimeProvider

Operating Modes

Operating Modes

You can configure the TimeProvider to operate in one of three modes:

Synchronization Supply Unit (SSU), Subtending (SUB) as defined by Telcordia

GR-378 Section 7, or Primary Reference Receiver (PRR) when the GPS input is available. Each mode is unique in its operation, and is defined in the following paragraphs.

SSU Mode

This is the TimeProvider’s default operating mode. Valid signals on the PRS, INP1,

INP2, or GPS connectors can be selected as the system reference. In this mode, the INP1 and INP2 inputs cannot be provisioned to receive Composite Clock (CC) signals, including JCC or JCC4. The method of selecting the system reference is

described in Selecting the Input , on page 32.

SUB Mode

This mode allows the TimeProvider to operate as a Remote shelf where phase is critical. When you select the SUB mode, INP1 and INP2 are automatically set for

CC inputs (including JCC and JCC4). Outputs provisioned for CC are phase-aligned with the selected CC input reference. Other output types comply with G.703 and

GR-1244.

To configure the TimeProvider for Subtending mode, see Setting the System Mode , on page 96.

PRR Mode

In PRR mode, the GPS is automatically selected as the system reference input.

This requires that you connect a GPS signal through the TPIU to the TimeProvider using the provided interconnect cable. This mode complies with ITU-T G.811 and

Telcordia GR-2830 requirements for Primary Reference Receivers/Clocks. Valid signals on the PRS, INP1, or INP2 connectors are used in conjunction with BesTime to extend compliance with GR-2830/G.812 standards.

The PRR mode uses Symmetricom’s BesTime servo control that allows the

TimeProvider to continue providing outputs in case GPS tracking is lost, the GPS data loses integrity, or if the IMC is removed from the shelf.

BesTime , on page 39

provides more information on the BesTime technology.

To configure the TimeProvider for PRR mode, see Setting the System Mode , on page 96.

TimeProvider User’s Guide 097-58001-02 Revision C – August 2005

Chapter 1 Overview of the TimeProvider

Performance Monitoring

Performance Monitoring

The TimeProvider can monitor and qualify all enabled input signals based on phase measurements. It measures the phase differences between the inputs and the output of the corrected clock. From these phase measurements, the TimeProvider computes frequency offset and wander of the input signals. Wander is reported in terms of Maximum Time Interval Error (MTIE) and Time Deviation (TDEV) and creates phase, MTIE, TDEV, and Fractional Frequency Offset (FFOFF) reports.

Performance data is automatically gathered on all enabled or monitored inputs.

Using MTIE and FFOFF data, the TimeProvider qualifies inputs based on these metrics. User-specified thresholds can be set to disqualify inputs and generate corresponding alarms, causing the TimeProvider to switch references or enter the

Holdover mode.

For more information on performance monitoring, see

Using Performance

Monitoring , on page 108. The

TimeProvider TL1 Reference Guide

contains a section describing the TL1 commands related to performance monitoring.

Phase Measurements

The IOC measures and transfers 1-second phase data with 100 ns resolution from each enabled input to the IMC every 10 seconds. This phase data is averaged to a

1 ns resolution, which is used to produce a 1-minute phase data sample. The 1 ns data sample is the basis for MTIE, TDEV, and FFOFF calculations. The phase data is not used to qualify an input reference source.

TL1 commands are available to display the 60 most recent phase data (at 100 pS resolution) measurements, the previous 86400 1 ns data averages, and the previous 10080 samples of 1-minute 1 ns-resolution data.

MTIE Calculations

MTIE is a measure of the relative noisiness of an input signal that relates to frequency offsets and phase transients. The TimeProvider automatically calculates

MTIE for each enabled input from the 600 most recent 1-second phase updates.

From this calculation, you can retrieve MTIE values for 1, 5, 10, 50, 100, and

500-second windows. You can set an alarm threshold for each of these windows; if the MTIE value exceeds this threshold and the alarm level is set to Minor or higher, the TimeProvider generates an alarm.

You can use the automatic MTIE calculations to qualify each input with user-defined qualification thresholds. If an input exceeds the threshold, then the input reference automatically switches to the next-best input.

097-58001-02 Revision C – August 2005 TimeProvider User’s Guide

25

Chapter 1 Overview of the TimeProvider

Physical Description

You can also set thresholds using pre-defined masks according to ANSI T1.101 (for

PRS inputs), ITU-T G.811 (for PRC inputs), or ITU-T G.812 (for Type I and Type II/III inputs). The TimeProvider performs a second MTIE calculation using the previous

24-hour period; this calculation is not used to qualify inputs.

TDEV Calculations

TDEV is a measure of the relative noisiness of an input signal that relates to its spectral content. The TDEV for each enabled input is automatically calculated from the previous 24-hour period. The TDEV value is used for monitoring only and is not used for qualifying an input signal.

You can retrieve the TDEV values for the following integration times: 1, 5, 10, 100,

500, 1000, 5000, and 7200 (84000/12) seconds.

FFOFF Calculations

FFOFF is a measure of the frequency deviation of the input signal against the system reference, expressed as a ratio. The TimeProvider automatically calculates

FFOFF for each enabled input from the 600 most recent 1-second phase updates.

You can use the automatic FFOFF calculations to qualify each input with user-defined qualification thresholds. If an input exceeds the threshold and the alarm level is set to Minor or higher, then the input reference automatically switches to the next-best input.

The TimeProvider stores historical FFOFF measurements for each enabled input every 60 seconds. You can retrieve FFOFF data for the prior 24 hours, depending on the number of faults that have occurred.

Physical Description

The TimeProvider consists of a shelf, plug-in cards, connector adapter panels for the cards, cables, hardware, and software. The TimeProvider is available in two configurations: front access (Model 1000) and rear access (Model 1100), as shown

in Figure 1-1

TimeProvider User’s Guide 097-58001-02 Revision C – August 2005

Chapter 1 Overview of the TimeProvider

Functional Description

Input Module

The Input module receives the incoming reference signals and contains the alarm input/output connector. A variety of connector modules allows you to select the connector style and input impedance to match the wiring system at the installation site.

Information Management Card (IMC)

The Information Management Card, known as the IMC, contains a processor that manages communications between the two IOCs and the serial and Ethernet communications ports. It also provides communication to the GPS receiver in the antenna; if the IMC fails or is removed, GPS operations cease.

Input/Output and Clock Module (IOC)

The TimeProvider operates with one or two IOCs. A second IOC in the shelf provides protection should the primary IOC fail. The IOC accepts the incoming reference signal and decodes the SSM, if present.

With the system properly provisioned and a reference signal selected, the local oscillator in the IOC operates in one of the following states:

Warm-up – For up to 20 minutes after applying power to the shelf, the IOC operates in warm-up mode.

Fast-lock – After warm-up is complete, the IOC enters the fast-lock state, where it quickly frequency-locks the local oscillator to the reference input.

Normal lock – After the IOC has completed the fast-lock cycle, it enters the normal lock mode, in which the TimeProvider uses the proper amount of filtering for the selected mode. When set to the SSU mode and locked to an active input traceable to a Primary Reference Source (PRS), the TimeProvider complies with the G.811 and GR-2830-CORE standards.

Holdover – If the reference signal is lost, then the clock enters the holdover mode. The accuracy of the TimeProvider output is then dependent on the quality level of the oscillator in the IOC.

Free-run – If the IOC starts without a system reference, the TimeProvider enters the free-run state after warm-up. If a reference is applied, then the TimeProvider enters the fast-lock and then the normal-lock states.

Bridging – In the event that all input references are lost, the TimeProvider goes into the bridging mode where the outputs continue to provide accurate timing outputs for a limited amount of time. If the inputs have not been requalified before the bridging time has elapsed, then the TimeProvider enters the holdover mode.

After the IOC has been in the Normal lock mode for at least three days, SmartClock holdover mode becomes available. Compared to the normal holdover mode, this mode provides a superior output quality.

Chapter 1 Overview of the TimeProvider

System Power

Output Module

The Output module provides the output connectors for the TimeProvider. You can install up to four Output modules on the main shelf. Like the Input module, each

Output module uses one of a variety of connectors that match the wiring system at

the installation site. Making Output Connections , on page 60, describes the Output

Modules available for the TimeProvider and the Expansion Panel.

Retimer Module

The Retimer module allows you to reshape, reamplify, and retime up to two E1 or T1 signals applied to the module and then deliver the improved signal to a connected

Network Element. You can install a Retimer module in any of the four slots used by

Output modules, but not in the available Expansion Panel. The T1 Retimer supports

line build-out (LBO) of up to 655 ft. Making Retimer Connections , on page 62, and

Provisioning the Retimer Module , on page 112, provide more information on using

the Retimer module.

Expansion Panel

The Expansion Panel provides up to 32 additional outputs that the TimeProvider

can generate. See Expansion Panel , on page 22 and

Rack Mounting the Shelf and

Expansion Panel , on page 51 for more information.

TimeProvider Interface Unit

The TimeProvider Interface Unit (TPIU) provides power, communication, and a composite timing reference signal between the antenna and the TimeProvider main shelf. During antenna installation, you can use the LEDs on the TPIU to detail the status of the received power and antenna communication. See

Making GPS

Connections , on page 64 for more information.

System Power

The TimeProvider main shelf has redundant –48v DC inputs. The inputs are diode or’d; in the event that one supply fails, the other takes over. The –48v returns are isolated from the chassis and circuit grounds. A 5 A fuse on the IOC protects the

TimeProvider; the shelf is protected from damage in case the connections are reversed.

The power supply range is from –36 to –72 V DC. The power requirements vary according to the type of IOC installed;

Chapter 1 Overview of the TimeProvider

Communication Ports

The procedure for installing power is described in Making Power Connections , on page 54.

Communication Ports

The TimeProvider contains three communications ports that allow you to provision, monitor, and troubleshoot the shelf. The Ethernet and Remote serial ports are located on the shelf, and the local Craft serial port is located on the IMC. You communicate with the TimeProvider using the TL1 protocol.

You can select one of four security levels for each user; each level has varying

levels of access to provisioning parameters. See Defining the Security Parameters , on page 90.

Ethernet

An Ethernet connector provides connectivity to an Ethernet local area network.

Each main shelf has a unique internet protocol (IP) address. Once the IP address is set and a connection is made to a LAN, you can access the TimeProvider on an intranet.

The Ethernet port supports up to 10 simultaneous connections to port 5000.

Local Craft Serial Port

This EIA-232 port supports local control; you can configure the TimeProvider with

TL1 commands using a terminal or personal computer (PC) with terminal emulation software or Symmetricom’s craft software, SynCraft. The connector is located on the front panel of the IMC. The default specifications are 9600-8-N-1. The Local port is configured as a DCE interface.

Remote Serial Port

The Remote serial connector can be used in the same manner as the local Craft serial port. The Remote port has additional control support to manage an external modem for remote access. The Remote port is configured as a DTE interface.

Chapter 1 Overview of the TimeProvider

Reference Input Signals

Reference Input Signals

The Input module accepts one or two E1, 2.048 MHz analog, 1.544 MHz or 6.312

MHz analog (Japan-specific), T1, and Composite Clock (including JCC and JCC4) inputs on ports INP1 and INP2. The CC inputs are used solely for Subtending mode; if you provision INP1 or INP2 to a CC type, then Subtending mode is automatically enabled. You can also connect a 2.048, 5, or 10 MHz or

Japan-specific 1.544 MHz or 6.312 MHz input reference signal on the PRS port.

The TimeProvider accepts full-level signals or bridged signals (–20 dB); the inputs are terminated per G.703. You can also connect a GPS antenna via the

TimeProvider Interface Unit (TPIU) to the GPS Input port on the shelf.

Make the input connections using the procedures described in Making Input

Connections , on page 57, then provision the inputs using the software commands

described in Provisioning the Input Reference , on page 99.

Input State

You can provision each input to one of three states:

Disabled

– the input is not used

Monitor

– the system monitors the input for signal faults and performance data, but it cannot be selected as the system reference

Enabled

– the system monitors the input for signal faults and performance data.

The input can be selected as the system reference in SSU or SUB mode or as a backup reference in PRR mode.

Selecting the Input

Many considerations influence which system reference you choose:

SSM or User-assigned Quality Level

User-assigned Priority Level

Switching mode

User-assigned Input State

Active alarms on an input

You can provision the TimeProvider to automatically select the highest-quality input based on priority and performance qualification, or you can manually select the input signal you want to use. If that signal becomes disqualified for any reason, the local oscillator goes into the Holdover mode.

TimeProvider User’s Guide 097-58001-02 Revision C – August 2005

Chapter 1 Overview of the TimeProvider

Reference Input Signals

Revertive Switching

Telcordia GR-378 and GR-1244 define two reference selection modes: Revertive and Non-revertive. In the revertive mode, when an input used as the system reference is disqualified (for any reason), if that input returns, it reverts to the system reference when the disqualifying reason is removed. The system reference switches two times: once when the disqualifying event occurs, and again when the input is no longer disqualified. In the non-revertive mode, the system reference does not revert to the initial input when the reason for disqualification is removed. The system reference switches only once when the disqualifying event occurs.

Quality Level and Priority Level

When the REFMODE parameter is provisioned to AUTO, the system reference switches when the input signal is disqualified. When the input signal is re-qualified, the TimeProvider can either keep the current reference or switch back to the re-qualified signal. When the REFMODE parameter is set to FORCED, then the reference does not switch and remains locked to that reference and the local oscillator enters Holdover mode if the input is not re-qualified. You may also provision the REFMODE parameter to FORCED to select an input as the system reference regardless of the priority levels of other outputs. If this input is lost or is disqualified, then the REFMODE automatically changes to AUTO and the next available reference based on priority and QLEVEL becomes the system reference. If no other input references are available, the TimeProvider enter the Holdover mode.

The QLEVEL ( Setting the Input Quality Level , on page 104) and the PRIORITY

( Setting the Input Priority Level , on page 105) parameters work together with SSMs

to determine the switching strategy for the inputs when the unit is in the SSU mode.

If the active/primary input becomes unavailable, the switching strategy determines which input to use: the TimeProvider uses the input with the next highest QLEVEL.

If all inputs have the same QLEVEL, then the TimeProvider uses the input with the highest PRIORITY.

To provision the TimeProvider as non-revertive, you must provision the user-assigned

Priority Level on all inputs to the same value. To provision the TimeProvider as revertive, you provision any one of the inputs to a different Priority Level.

If the original primary input becomes available again, the REFMODE, QLEVEL and

PRIORITY parameters determine whether the TimeProvider switches back to that input. If REFMODE is set to AUTO, then the reference switches according to the

QLEVEL and PRIORITY settings. If the QLEVEL and/or PRIORITY parameter of the original input is higher than the current input, the TimeProvider

reverts

back to the original input. If the QLEVEL parameter is the same for all inputs, then the

TimeProvider does not revert back to the original input.

SSMs and Quality Level

Synchronization Status Messages (SSMs) can be included in the bit stream of the incoming signal to indicate its quality level. You must provision the input to read the

SSM, and you must provision the bit position of the incoming SSM.

If the incoming signal does not include SSMs, or if you disable them, then you can provision the Quality Level to an appropriate value. The QLEVEL value is used in the same manner as the incoming SSM to determine which input is used when the active input is disqualified. SSMs are described in more detail in

Synchronization

Status Messages (SSMs) , on page 37.

SSU Mode

Table 1-2 illustrates which input is the active system reference under several

different input conditions when the TimeProvider is in the SSU mode.

Clock Performance

Clock Performance

Two IOCs are available:

A Rubidium-based version that meets ST2/Type II standards. This IOC meets or exceeds the ITU G.812 Type II specification.

A Quartz-based version that meets ST3E/Type I standards. This IOC meets or exceeds the ST3E requirements in ANSI T1.101 and Telcordia GR-1244, as well as the ITU-T G.812 TYPE III specification and ITU-T G.812 Type I specification.

Output Signals

The main shelf has 32 output connections arranged in four groups of eight outputs; using the optional Expansion Panel, you can expand to 64 outputs. The outputs are

“universal,” and can supply E1, 2.048 MHz, T1, 8 kHz, CC, JCC, JCC4, 1.544 MHz, and 6.312 MHz signals. E1 and T1 signals can be provisioned with standard framing and G.703 formats. You provision the outputs in groups of eight outputs (or 16 outputs if the optional Expansion Panel is installed).

The TimeProvider use interchangeable Output modules, allowing you to select the connector and termination impedance. Output modules are available with the following connectors:

BNC – 75

DB9 – 120

Metric (Siemens) 1.6/5.6 – 75

Metric (Siemens) 1.0/2.3 – 75

Wirewrap – 100

BT43 – 75

Each Output module plugs into the shelf (and Expansion Panel) and provides connectors and terminations for eight outputs. Make the output connections using

the procedures described in Making Output Connections , on page 60. You provision

the output signal type using the software commands described in

Provisioning the

Outputs , on page 111.

Chapter 1 Overview of the TimeProvider

Alarms

Alarms

The TimeProvider uses alarms to notify you when certain conditions are deteriorating below user-specified levels. These alarms are indicated by shelf and card status lamps (LEDs) and by TL1 messages reported over the serial/EIA-232 or LAN communication ports. In addition, the input panel has a connector that provides contact closures to activate external alarms.

You can provision the alarm level for most alarms to one of the following levels: non-reportable (NR), non-alarm event (NA), minor (MN), major (MJ), or critical (CR).

Alarms related to the inputs are special cases; you can only provision input alarms for minor, major, or critical. To help prevent spurious or transient input alarms, a delay timer (FLTDELAY) allows you to provision a waiting period that starts after the alarm condition occurs; the alarm is set at the end of the period. A similar timer

(CLRDELAY) clears the alarm after the alarm condition is no longer present.

Recommendation:

To prevent Non-Service Affecting LOS alarms, Symmetricom recommends that you provision unused inputs to the Disabled state.

For more information on connecting alarms, see Making Alarm Connections , on page 63. For information on provisioning alarm levels, see

Provisioning the Alarm

Levels , on page 114.

Synchronization Status Messages (SSMs)

The TimeProvider supports input and output SSMs. SSMs provide a method for providing clock quality information to any equipment that uses synchronization inputs.

Table 1-4 describes the ANSI SSM values and the traceability associated

with each value.

The TimeProvider handles SSMs in accordance with T1X1.3 TR33, T1.101-1999,

GR-253, and 379-CORE.

Input SSMs

The TimeProvider extracts and decodes the SSM (if present) on the available inputs. Using this information, the TimeProvider can automatically select the input with the higher quality level.

You can manually provision the input quality level for those signals that do not have

SSM information or you can provision INP1 and INP2 to read the SSM on the input; in either case the quality level of the reference input becomes the system’s quality level, which is passed through to the outputs in the output SSM. If the IOC enters the Free-run or Holdover mode, the system’s quality level is determined by the

CLKTYPE parameter for the local oscillator on the selected IOC module. You can provision the CLKTYPE parameter to Type I, Type II, ST2, or ST3E.

Output SSMs

You must provision the TimeProvider’s outputs according to the type of SSM operation you are using:

For ANSI SSM operation, set the output type to Extended SuperFrame (ESF) for

ANSI SSM operation

For ITU SSM operation, set the output type to Channel Associated Signaling

(CAS) with CRC4 framing (this setting is automatically set when you enable SSMs)

38

TimeProvider User’s Guide 097-58001-02 Revision C – August 2005

Chapter 1 Overview of the TimeProvider

SmartClock

These output formats automatically generate SSMs. The system output quality level depends on the input quality level of the input signal or the local oscillator’s quality level. During normal operation, when a qualified input is used as the active timing reference, the TimeProvider copies the input’s quality level to all DS1 ESF outputs and E1 CAS4 outputs. T1 SSM messages are mapped to the corresponding equivalent E1 SSM message and vice versa.

If the IOC is operating in Holdover mode for any reason, the SSM quality is the internal level of the oscillator installed in the IOC.

SmartClock

The TimeProvider uses Symmetricom’s SmartClock technology, which predicts frequency changes due to aging of the local oscillator in the IOC; this offsets this deterministic behavior by steering the output with a corrected deviation.

The TimeProvider begins the learning process as soon as you apply a valid external reference source. The SmartClock technology is enabled after 24 hours of continuous lock; the TimeProvider then issues an event message similar to this:

IOC1,EQPT,NA,SCAVAIL,NSA,04-12-14,12:13:14:\”SMARTCLOCK

ALGORITHM, ENABLED\”

If you reset the IOC or if the oscillator becomes less stable (for example, due to extreme temperature swings), the TimeProvider disables SmartClock and issues an event message similar to this:

IOC1,EQPT,NA,SCAVAIL,NSA,04-12-17,15:16:17:\”SMARTCLOCK

ALGORITHM, DISABLED\”

The TimeProvider automatically restarts SmartClock, which then begins to determine a new aging rate for the oscillator.

BesTime

The TimeProvider uses Symmetricom’s BesTime algorithm when it is in the PRR mode to provide enhanced GR-2830-CORE performance during bridging or holdover situations. BesTime minimizes the effect of transients on the reference signal on the outputs of the TimeProvider by comparing them against the system reference to produce the most stable outputs from the TimeProvider.

097-58001-02 Revision C – August 2005 TimeProvider User’s Guide

39

Chapter 1 Overview of the TimeProvider

BesTime

The BesTime algorithm is based on Symmetricom’s patented use of multiple-input phase-locked loops (MPLLs) to generate a correction signal for the local oscillator

(LO) in the IOC. With GPS as the primary input signal in PRR mode, the signals on the PRS, INP1 and INP2 inputs may be enabled and used in the BesTime ensembling algorithm to generate output signals derived from the optimum weighting of each input.

Two weighting algorithms - tracking and holdover - determine which of the inputs are used as the ensembled reference. The tracking algorithm is used during normal operation. If the GPS becomes disqualified, BesTime uses the holdover weighting algorithm to determine what the GPS input would have been had it not been lost.

You can use the RTRV-BESTIME-STATS command to view the current weighting for each input.

The BesTime control loops are designed so that the short-term (under 10 minutes) stability is controlled by the LO, medium-term (10 minutes to several hours) stability is controlled by the ensembled reference, and long-term stability and accuracy is determined by the GPS control input.

The control loops can use either measurement data or prediction data. The inputs are measured for phase, frequency, and drift transients. When the input to either loop is determined to be valid, then the measured data is used to generate the correction signal to the local oscillator. If BesTime detects a transient on the input, it switches to the prediction data before the transient can start to affect the correction signal.

Normal Tracking

During normal GPS tracking, the GPS input provides the source of long-term stability for all inputs to the ensembling algorithm. The ensembling improves the medium-term stability of the output signals.

GPS Holdover

If GPS signals are lost, then all inputs to the ensembling algorithm have lost their source of long-term traceability. BesTime substitutes the inputs with calibration predictions with respect to GPS. Each input is weighted according to the estimated prediction error over 24 hours.

Making Ground Connections

Use the procedure in this section for both the main shelf and the Expansion panel.

After installing the TimeProvider shelf and/or the Expansion panel into the rack, make the grounding connections as follows.

Recommendation:

Although there are a number of methods for connecting the equipment to earth ground, Symmetricom recommends running a cable of the shortest possible length from the ground lug to earth ground.

Front Access Shelf

To connect Chassis Ground on the front access chassis, connect a cable from the frame ground lug on the left side of the front panel to the proper grounding zone or master ground bar.

Rear Access Shelf

To connect Chassis Ground on the rear access shelf, connect a cable from Pin 3 of the power connector to the proper grounding zone or master ground bar.

Expansion Panel

All connections to the Expansion Panel, including chassis ground, are made using the interconnection cable.

Making Power Connections

The TimeProvider front- and rear-access shelves use different types of power connectors. Each shelf is delivered with the appropriate connector and shell.

Electrical Shock Caution:

To avoid possible injury from shock, make sure that the fuses are removed from the fuse panel or power supply before connecting or applying power to the unit.

Warning:

For continued fire protection, replace power supply fuse(s) with the specified type and a 5 A rating. There are no user-serviceable fuses in the TimeProvider shelf.

This unit must be grounded.

Refer all servicing to qualified personnel.

Chapter 3 Installing the TimeProvider

Making Connections

Figure 3-14. Metric (Siemens) Output Module and T1 Retimer Wirewrap Output Module

Making Retimer Connections

The Retimer module (shown in

Figure 3-14

) performs reshaping, reamplifying, and retiming on a signal connected to the IN pins on Side 1 (East) and sends that signal to a Network Element (NE) connected to the OUT pins on Side 1. The signal returns from the NE on the IN pins of Side 2, where it is reshaped and reamplified and sent

back to the network on the OUT pins of Side 2. Figure 3-15 illustrates how to make

connections to Channel 1 of the Retimer module. See

Provisioning the Retimer

Module , on page 112, for the commands to set up the Retiming module.

You can install a Retimer module only in the TimeProvider main shelf in any of the four Output groups (A, B, C, or D). When you install a Retimer module in any Output group in a main shelf, the corresponding group on the Expansion Panel can be user-programmed to any of the output signal types supported by the TimeProvider.

For example, if Group A on the main shelf has the T1 Retimer module installed, then

Group A on the Expansion Panel could have a 2.048 MHz analog output. When an output group on the main shelf is used for output signals only (no Retimer module is installed), then the corresponding group on the Expansion Panel has the same output signal as on the main shelf. For example, if Group A on the main shelf has

2.048 MHz outputs then Group A on the Expansion Panel also has 2.048 MHz outputs.

Chapter 4 Provisioning the TimeProvider

TL1 Overview

TL1 Overview

The TimeProvider uses the TL1 syntax; this chapter and the

TimeProvider TL1

Reference Guide

describes command lines and responses. For a complete description of the TL1 syntax, refer to Telcordia (Bellcore) Technical Reference

TR-NWT-00831 and TR-NWT-00833.

TL1 Command Structure

The TL1 commands you issue to the TimeProvider use the following structure: verb-modifier:|tid|:|aid|:[<ctag>]::|<keyword>|=<value||; where:

: (colon) is a block separator

, (comma) is a parameter field separator

; (semicolon) is the terminating character for commands and responses

[ ] (square brackets) indicate optional parameters

Adjacent colons indicate unused fields. If an unused field is the last parameter in the list, for example the general block or the parameter block, you can omit the colon and simply type the semicolon.

If you enter a space in the command string, the TimeProvider ignores it.

TL1 commands are not case-sensitive.

Table 4-1 describes the syntax used in this manual.

Chapter 4 Provisioning the TimeProvider

TL1 Overview

TL1 Response Format

Normal Response

For each TL1 command described in this chapter there is a normal response, an in-process response, or an error response. The TimeProvider response is always upper-case. The format of a normal response is:

<cr><lf><lf>

^^^sid^date^time<cr><lf>

M ^ctag^COMPLD<cr><lf>

;

The time and date is in the Telcordia GR-833 format. A sample normal response is:

TIMEPROVIDER 03-08-28 11:23:54

M 1 COMPLD

;

In-Process Response

The TimeProvider sends an in-process response only if it cannot respond to the command within two seconds. The response terminates with a less-than character

(<) with no semicolon until after the TimeProvider sends the requested output response message. The format of the in-process message is:

<cr><lf><lf>

^^^sid^date^time<cr><lf>

IP^ctag<cr><lf>

<

A sample in-process response is:

TIMEPROVIDER 03-08-28 11:24:15

IP^2

<

Error Response

If you mis-type a command or issue an invalid command, the TimeProvider sends an error message. The format of the error response is:

<cr><lf><lf>

^^^sid^date^time<cr><lf>

M ^ctag^DENY<cr><lf>

^^^<errcde><cr><lf>

;

A sample error message is shown below:

Chapter 4 Provisioning the TimeProvider

Starting the TimeProvider for the First Time

The TL1 command may generate an event message specific to the command. This event message accompanies the command description in this chapter.

Autonomous Messages

In addition to the TL1 response messages described in the above sections, the

TimeProvider returns Autonomous Messages to report alarms, configuration changes, or condition changes. Frequently, an Autonomous Message is returned at approximately the same time as the TL1 response message that is associated with a command, because the command happens to change the unit’s state.

Autonomous Messages are not directly correlated with commands, and therefore they do not contain a correlation tag (ctag).

The TimeProvider can generate an Autonomous Message at any time, whether to report that a user-initiated change has occurred, to report that an active alarm condition exists, or to report that an alarm has been cleared. The format of the

Autonomous message is as follows; note that the text REPT identifies the response as a Autonomous Message.

<cr><lf><lf> sid date time <cr><lf> almcde atag REPT reptype aidtype<cr><lf> aid,aditype:ntfcncde,condtype,srveff,ocrdat,ocrtim:condscr

”<cr><lf>

;

Refer to the

TimeProvider TL1 Reference Guide

for more information on

Autonomous Messages.

Starting the TimeProvider for the First Time

The TimeProvider is delivered with a copy of SynCraft, Symmetricom’s network management application. Before you can use SynCraft or other network management software, you

must

provision the following parameters, as described in this section and in

Setting Communications Parameters , on page 86:

Security-level user

Source ID (sid)

Date and time

Serial communications parameters

Ethernet parameters

Appendix B, CRAFT Software Reference

, provides procedures and instructions to get started using the SynCraft application.

82

TimeProvider User’s Guide 097-58001-02 Revision C – August 2005

Chapter 4 Provisioning the TimeProvider

Starting the TimeProvider for the First Time

Powering Up the TimeProvider

To power up the TimeProvider, perform one of the following tasks, as appropriate:

Connect the power leads from the power supply (see Making Power

Connections , on page 54)

Install the fuse in the fuse panel

Turn on the power supply

LED Indications on Power-up

The LEDs on the IMC, IOC, and TPIU (if present) illuminate in the following sequence:

The LEDs on the TPIU remain off until the Master shelf has completed its power-on testing and the GPS input has been enabled. The TPIU and Antenna Power LEDs light green and the Antenna Signal LED lights red. When the Master shelf completes its power-on testing, the Antenna Signal LED lights green, indicating that the TPIU is receiving a valid signal from the antenna.

Logging In for the First Time

To log in to the TimeProvider for the first time:

1. Connect a straight-through serial cable to the local Craft port. Connect the other end of the cable to a computer.

2. Start a terminal emulation program such as HyperTerminal or ProComm Plus.

Configure the program for 9600 baud, 8 data bits, No parity, and 1 stop bit.

3. Type

;

(semicolon). If the TimeProvider responds with a Deny response, you have established communications. If you do not receive the Deny response, check the connections, the cable, and the program settings.

Defining a User at the Security Access Level

Recommendation:

To avoid a possible service call to unlock the

TimeProvider, Symmetricom recommends that you enable the security feature by defining a user at the Security access level.

TimeProvider Access Levels

The security measures built into the TimeProvider are based on a list of users authorized to access the unit. Each user has their own password and is assigned to one of the following access levels: NONE, USER, ADMIN, or SECURITY. Users can

issue the TL1 commands available at their access level. Managing the User List , on page 90, describes how to manage the user list.

If you do not define a Security-level user, the security features are not enabled and an unauthorized user could gain access to the TimeProvider and compromise the security of your network.

097-58001-02 Revision C – August 2005 TimeProvider User’s Guide

83

Chapter 4 Provisioning the TimeProvider

Starting the TimeProvider for the First Time

If you define a user at a level other than Security

before

you define a Security-level user, you cannot execute Security-level commands. You will need to contact

Symmetricom Global Services to correct this problem.

Recommendation:

Symmetricom recommends that you record and store the Security-level user’s name and password in a secure location.

Adding a User at the Security Access Level

To define a user at the Security access level, issue the following TL1 command:

Sample Command

ENT-USER-SECU::DEPTHEAD:TS1000::”TP01!”,SECURITY;

This sample command creates a user with the name DEPTHEAD and a password of TP01!; this user is at the Security access level. See

Adding a User , on page 92,

for more information on the ENT-USER-SECU command.

;

Logging In

You can now log in using the ACT-USER command and the new user name and password to continue with the provisioning process.

Sample Command

ACT-USER::DEPTHEAD:TS1000::TP01!;

Normal Response

TP-SSU 03-05-15 09:59:15

Chapter 4 Provisioning the TimeProvider

Defining the Security Parameters

Defining the Security Parameters

The TimeProvider supports users at the following four access levels:

None

– Anyone with access to a serial or Ethernet port on the TimeProvider can issue commands set to this access level. If no Security-level users are defined, then anyone connected to the TimeProvider can issue every command available

User

– Users entered into the user list at the User level can issue commands set at the User access level

Admin

– Users entered into the user list at the Admin level can issue commands set at the Admin access level

Security

– Users at this access level can issue every command available

You can edit the commands available at each access level using the

ED-CMD-SECU command. You can display the current access level for each command by issuing the RTRV-CMD-SECU command. See the

TimeProvider TL1

Reference Guide

for details on these commands. Record the values you provision

in Table 4-3

.

The first person to log into the TimeProvider is automatically assigned the Security

access level (described in Defining a User at the Security Access Level , on page

83); this person normally performs the initial provisioning and defines users and

their appropriate access levels.

Managing the User List

Use the procedures in this section to manage the users that are authorized to access the TimeProvider.

Logging In

Use the following TL1 command to log existing users into the system.

ACT-USER:[<tid>]:<uid>:[<ctag>]::<pid>;

Chapter 4 Provisioning the TimeProvider

Provisioning the IOC

Provisioning the IOC

This section describes how to provision the IOC.

Setting the System Mode

The SET-SYS-MODE command allows you to provision the operating mode of the

TimeProvider to one of the following:

SSU – Synchronization Supply Unit: provides filtering compliant with G.812 and

GR-1244

SUB – Subtending mode: provides composite clock input tracking compliant with

GR-378

PRR – Primary Reference Receiver mode: provides ITU-T G.811 and Telcordia

GR-2830 requirements for Primary Reference Receivers/Clocks

In the SSU mode, you can select the system reference from signals on the PRS,

INP1, or INP2 connectors.

In the SUB mode, the PRS input is set to Monitor only; you can select the system reference from signals on the INP1 or INP2 connectors. You can provision these inputs to Composite Clock signal types only when the TimeProvider is in SUB mode.

In the PRR mode, the antenna provides GPS signals as the primary reference. You can use qualified and enabled signals on INP1 and INP2 to enhance the stability of the output signals based on the BesTime algorithm.

Setting the System Mode

Use the SET-SYS-MODE command to provision the TimeProvider’s operating

mode. See Operating Modes , on page 24, for more information on how the

operating mode affects the TimeProvider’s inputs and outputs.

SET-SYS-MODE:[<tid>]::[<ctag>]::<keyword>=<value>;

Controlling Automatic Reference Switching

The TimeProvider can determine which input reference signal has the highest quality. When the active reference signal falls below a preset quality level, the

TimeProvider can automatically switch to the next highest input reference signal. To use this feature, you must enable Automatic switching.

You can also use the performance monitoring features to automatically switch the input reference signal when user-defined performance thresholds are crossed. See

Setting MTIE and FFOFF Thresholds , on page 108 for more information on setting

and using performance monitoring commands.

Chapter 4 Provisioning the TimeProvider

Provisioning the Input Reference

Automatic Return to a Higher Priority Reference

When the REFMODE parameter is provisioned to AUTO, the system reference switches when the input signal is disqualified. When the input signal is re-qualified, the TimeProvider can either keep the current reference or switch back to the re-qualified signal. The first case, keeping the current reference, is also known as

“non-revertive” mode; the second case, switching back to the re-qualified input, is known as revertive mode.

The QLEVEL ( Setting the Input Quality Level , on page 104) and the PRIORITY

( Setting the Input Priority Level , on page 105) parameters work together with SSMs

to determine the switching strategy for the inputs when the unit is in the SSU mode.

If the active/primary input becomes unavailable, the switching strategy determines which input to use: the TimeProvider uses the input with the next highest QLEVEL.

If all inputs have the same QLEVEL, then the TimeProvider uses the input with the highest PRIORITY.

To provision the TimeProvider as non-revertive, you must provision the user-assigned Priority Level on all inputs to the same value (1, 2, 3, or 4). To provision the TimeProvider as revertive, you provision any one of the inputs to a higher or lower Priority Level, with 1 being the highest priority.

If the original primary input becomes available again, the REFMODE, QLEVEL and

PRIORITY parameters determine whether the TimeProvider switches back to that input. If the QLEVEL and/or PRIORITY parameter of the original input is higher than the current input, the TimeProvider

reverts

back to the original input. If the QLEVEL parameter is the same for all inputs, then the TimeProvider does not revert back to the original input.

Enabling Automatic Switching

Use the ED-SYNC command to set the reference selection to Automatic or Forced.

When set to Automatic, then the QLEVEL and PRIORITY parameters determine the switching strategy to be revertive or non-revertive. When set to Forced, then the

TimeProvider uses the input selected with the INPREF keyword (see

Manually

Selecting the Reference , on page 105).

Setting the Input Quality Level

Use the ED-SYNC command to set the quality level (QLEVEL) of the specified input. You set the QLEVEL when using inputs that do not have an associated SSM, or when you want to set an alarm threshold for inputs that have SSMs. The

QLEVEL determines the TimeProvider’s output SSM.

If you provision QLEVEL below the quality level of the local oscillator in the IOC, then the TimeProvider disqualifies the input with the INPQL alarm. An INPQL alarm also occurs if the incoming SSM indicates that the input signal is below the quality level of the local oscillator or if the incoming SSM is below the provisioned level.

Normally, you provision the QLEVEL for each input to be either unique or all the same. If you set all QLEVEL for inputs to unique values, then you have set up a revertive switching strategy. If you set all inputs to the same value, then you have set up a non-revertive switching strategy.

Provisioning the Outputs

This section describes the commands you use to provision the outputs of the

TimeProvider.

Enabling and Disabling the Outputs

Use the ED-EQPT command to enable or disable the output signal. This command affects the specified group of eight output channels, or sixteen output channels if the

Expansion panel is also used; individual channels cannot be enabled or disabled.

ED-EQPT:[<tid>]:<aid>:[<ctag>]::<keyword>=<value>;

This command has a default access level of ADMIN.

Enable the specified output group

Disable the specified output group

Default value

ENABLE

Sample Command

ED-EQPT::OUTA:TS1000::OUTSTATE=DISABLE;

This command disables output group A and turns off all eight channels, or sixteen channels if the Expansion panel is also used.

;

Provisioning the Output Framing Type

Use the ED-SYNC command to provision the output framing type.

CAS is the only available option for E1 output framing because the BITS/SSU clock in the TimeProvider generates the highest density ones signal available.

Downstream Network Elements (NEs) configured to receive CAS or CCS will accept the CAS output generated by the TimeProvider without errors.

This section describes how you provision and manage alarms in the TimeProvider.

There are TL1 commands that allow you to:

Provision individual alarm levels

Provision system-wide alarm levels

Display current alarm settings

Display current alarms

Display alarm status

Alarms are displayed on the IMC LEDs; they also appear on the relay contact closures on the Input module.

Provisioning the Alarm Levels

Use the SET-ATTR command to set the alarms associated with the IMC and IOC.

You can use this command to reset all alarm levels to the factory default values, and to allow the TimeProvider to escalate alarms.

Testing Alarm Conditions

Testing Alarm Conditions

Testing the IOC Operating Modes

Warm-up Mode

The IOC enters and remains in the Warm-up mode for approximately 30 minutes after you apply power to the shelf, or when you install the IOC into the shelf. The following actions occur when an IOC enters the Warm-up mode:

The Power LED on the IOC flashes green

An event is generated and stored in the event log

To verify that an IOC is in warm-up mode:

1. Apply an appropriate signal to the INP1, INP2, and/or PRS inputs.

2. Visually inspect the Power LED on the appropriate IOC. The LED is flashing green in the Warm-up mode.

3. Type

RTRV-ALM::IOC1;

(or

RTRV-ALM::IOC2;

). The TimeProvider responds with a complied message indicating that the designated IOC is in alarm.

Locked Mode

The IOC enters and remains in the locked mode after it has completed the warm-up cycle. The following actions occur when an IOC enters the Locked mode:

The Power LED on the IOC is green

An event is generated and stored in the event log

To verify that an IOC is in locked mode:

1. Visually inspect the Power LED on the appropriate IOC. The LED is continually green when the IOC is tracking at least one input.

2. Type

RTRV-LOG::IOC1:::EVT;

(or

RTRV-LOG::IOC2:::EVT;

). The

TimeProvider responds with a list of events related to the specified IOC. Look for the entry with the text “Clock entered lock mode.”

TimeProvider User’s Guide 097-58001-02 Revision C – August 2005

Chapter 5 Testing the TimeProvider

Testing Alarm Conditions

Testing the Reference Switching

To test the ability of the TimeProvider to switch references, you perform a two-step test:

Connect appropriate reference inputs to the TimeProvider.

Create a fault on the selected reference signal and observe that the

TimeProvider changes to the appropriate secondary input.

To test the reference switching:

1. Connect a suitable reference signal to the PRS input and a second reference signal to the INP1 input. Wait for the Qualified LEDs for both inputs to turn green and for the Active LED to light on the PRS input.

2. Issue the

ED-EQPT::PRS:::INSTATE=DISABLE;

command to disable the PRS input and force the TimeProvider to switch to the INP1 reference.

3. Observe that the Active LED changes from the original input to the secondary input (PRS to INP1 or INP1 to PRS).

Testing the Non-Revertive Operating Mode

When the TimeProvider is in the non-revertive operating mode, the input reference signal does not revert to the original input after it recovers from an error condition.

The TimeProvider is in non-revertive mode when the QLEVEL parameter for INP1,

INP2, and PRS inputs is set to the same value, and the PRIORITY parameters for the same inputs are set to the same level.

To test the non-revertive operating mode, perform the following steps:

1. Define the non-revertive mode by setting the QLEVEL and PRIORITY parameters to appropriate values. See

Setting the Input Quality Level , on page

104, and

Setting the Input Priority Level , on page 105, for further information.

2. Provision and connect appropriate reference inputs to the TimeProvider.

3. Create a fault on the selected reference signal and observe that the

TimeProvider changes to the appropriate secondary input.

4. Remove the fault on the initial reference signal and observe that the

TimeProvider does not revert to that initial reference input. The event log indicates that the reference signal is no longer in fault.

097-58001-02 Revision C – August 2005 TimeProvider User’s Guide

139

Chapter 5 Testing the TimeProvider

Testing Alarm Conditions

Testing the Revertive Operating Mode

When the TimeProvider is in the revertive operating mode, the input reference signal reverts to the original input after it recovers from an error condition.

The TimeProvider is in the revertive mode when the QLEVEL parameter for INP1,

INP2, and PRS inputs are set to different values, and the PRIORITY parameters for the same inputs are also set to different values.

To test the revertive operating mode, perform the following steps:

1. Define the revertive mode by setting the QLEVEL and PRIORITY parameters to appropriate values. See

Setting the Input Quality Level

, on page 104, and Setting the Input Priority Level , on page 105, for further information.

2. Provision and connect appropriate reference inputs to the TimeProvider.

3. Create a fault on the selected reference signal and observe that the

TimeProvider changes to the appropriate secondary input.

4. Remove the fault on the initial reference signal and observe that the

TimeProvider reverts to the initial reference input. The event log and the LEDs indicate that the input is no longer in fault, and that the reference has changed.

Testing the Power Alarms

To test the ability of the TimeProvider to detect and report problems with the battery power, you perform a two-step test:

Connect power to the TimeProvider on both Batt A and Batt B terminals

Remove power from one terminal and observe that the TimeProvider issues the appropriate alarm

When power is lost from the Batt A or Batt B terminal, the factory default alarm is

Major.

1. Connect the appropriate power supply to both the Batt A and Batt B connectors.

The TimeProvider enters the Warm-up mode.

2. Remove power from either the Batt A or Batt B terminal. Observe that the Major

LED on the IMC is red. Verify that a Major alarm is included in the event log.

140

TimeProvider User’s Guide 097-58001-02 Revision C – August 2005

Chapter 5 Testing the TimeProvider

Testing the Communication Ports

Detecting Input Errors

You can provision the TimeProvider to perform a variety of functions when an input error occurs. Possible errors include:

AIS - Alarm Indication Signal

LOS - Loss of Signal

OOF - Out of Frame

Loss of Alignment

Excessive wander

Input is disqualified

The TimeProvider reports these and other errors on the front panel alarm LEDs, in an autonomous event message, and via devices connected to the alarm relays. You can provision each error to a specific alarm level (Minor, Major, or Critical).

Setting an Alarm Strategy

You can set up the input alarms to prevent spurious input errors from triggering an alarm. The FLTDELAY keyword parameter sets a period from 1 to 15 seconds that an input error must be present before the alarm is issued. You can provision the alarm to clear from 1 to 1000 seconds after the input error clears using the

FREEFLT keyword parameter. Use the ED-SYNC command syntax described in

Provisioning System-Level Alarms , on page 121 to provision the FLTDELAY and

CLRDELAY keywords.

Testing the Communication Ports

The TimeProvider has three communication ports. This section describes how to test each port; if you do not plan to use a port, then you can skip the corresponding test.

Local Craft serial port

Remote serial port

Ethernet port

Testing the Local Craft Serial Port

The local Craft serial port is on the faceplate of the IMC, and is configured as a DCE device. The default settings for the local Craft serial port are 9600 Baud, 8 bits, no parity, 1 stop bit, echo on, and handshaking disabled.

To connect a device to the local Craft port, perform the following steps:

097-58001-02 Revision C – August 2005 TimeProvider User’s Guide

Repairing the TimeProvider

Repairing the TimeProvider is limited to replacing cards. Refer to Working With

Cards , on page 75, for information on how to properly handle cards and modules to

prevent electrostatic or physical damage.

To remove an IOC, loosen the captive screws and lift the removal tabs on each side of the card, then slide the module out of the shelf. To remove the IMC, loosen the captive screws and pull the module out of the shelf using the U-shaped handle on the front panel. Place the module on an anti-static surface or in an anti-static bag.

180 TimeProvider User’s Guide 097-58001-02 Revision C – August 2005

Chapter 6 Maintaining and Troubleshooting the TimeProvider

Obtaining Technical Assistance

To remove an Input or Output module, loosen the captive screws and then pull the module using the captive screw. Place the module on an anti-static surface or in an anti-static bag.

Warning:

To avoid possible electrostatic damage to the module or panel, place it in a static-free bag or on a static-free surface.

Obtaining Technical Assistance

If you have technical questions about the TimeProvider, call Symmetricom Global

Services (SGS) at 888-367-7966 (toll-free in USA only), 408-428-7907, or

+49 700 3288 6435 in Europe, Middle East, or Africa. You can also email your technical questions to [email protected] or [email protected].

Upgrading the Firmware

You can upgrade the firmware in the IMC or IOC using TL1 commands and software available from Symmetricom. Only users with Admin- or Security-level access can execute the command. The command places the management module in the firmware download mode and terminates all sessions except the session performing the upgrade. During the upgrade process, no new sessions are allowed. Refer to the

TL1 Reference Guide

for details on the upgrade process.

Caution:

To avoid a possible service call, do not issue a command to the TimeProvider, do not remove power from the TimeProvider, and do not remove an IOC or IMC from the shelf during the upgrade process. Doing so could corrupt the flash memory in a card, disabling the TimeProvider.

Use the following TL1 command to download the firmware.

ACT-SWDL:[<tid>]:<aid>:[<ctag>];

After you issue the command, you have 60 seconds to begin transferring the upgrade file using the Ymodem transfer protocol. If you do not start the transfer within 60 seconds, the command times out and you will have to issue the

ACT-SWDL command again. You can use the SynCraft application to transfer the upgrade file.

The system downloads the firmware using the Ymodem protocol; if the IMC firmware is upgraded, the processor in the IMC is reset.

097-58001-02 Revision C – August 2005 TimeProvider User’s Guide 181

Chapter 6 Maintaining and Troubleshooting the TimeProvider

Upgrading the Firmware

This command always has a security level of SECURITY.

IMC

<aid>

IOC

IOCm m = 1 | 2

Description

Downloads a new firmware image to the IMC.

If the IMC or IOC provisioning has changed in the newly upgraded firmware, you may need to issue the CPY-MEM command from an in-service IOC to the IMC before the IMC is fully functional. See the

TimeProvider TL1 Reference Guide

for more details.

Downloads a new firmware image to the IOC.

Symmetricom recommends that redundant IOCs use the same firmware revision.

The Active IOC enters Standby mode, putting the second IOC in Active mode. After acknowledging the changeover, the IMC starts the firmware transfer to the Standby

IOC.

After the download, the Standby IOC must achieve Lock (CLKLOCK) mode before changing again to Active mode. The Standby IOC is then upgraded.

If the first IOC upgrade is not successful, the entire process is aborted and an

SROF error message is generated. The IOC restarts with the existing firmware.

Downloads the IOC firmware image from the Active IOC to the Standby IOC.

This command does not require Ymodem or SynCraft to transfer an image file from the computer to the TimeProvider.

Sample Command

ACT-SWDL::IMC:TP1000;

If the image transfer takes more than 60 seconds to start, the error response is

SROF and the IMC returns to normal operation. You will need to start the download process again to perform the upgrade.

If the header information in the referenced file is not correct, the error response is

SROF, followed by a message that says the firmware upgrade was not successful.

If the file header is correct, the TimeProvider responds with a message stating that it is beginning the firmware upgrade, followed by a message stating the upgrade was successful.

Upgrading the IMC

To upgrade the software in the IMC, use the following procedure. You must have the upgrade software available on diskette or other media, as well as a Ymodem file-transfer program such as SynCraft available before you begin the procedure.

Outputs are not affected during the IMC upgrade procedure.

1. Log in to the TimeProvider with an Admin- or Security-level user id and password.

2. Back up the contents of the IMC memory in an IOC by issuing the following command:

182 TimeProvider User’s Guide 097-58001-02 Revision C – August 2005

Chapter 6 Maintaining and Troubleshooting the TimeProvider

Upgrading the Firmware

CPY-MEM:::::IMC,IOC,IMC;

3. To start the download, issue the command

ACT-SWDL::IMC:TP1000;

The TimeProvider issues an In-Process response, the TL1 connection closes, and the TimeProvider waits to receive the upgrade software using the Ymodem protocol.

4. Use a Ymodem file transfer program such as SynCraft to transfer the upgrade software to the TimeProvider. You must start the transfer within 60 seconds or the

TimeProvider issues a Deny response.

The TimeProvider validates the received file, updates the flash memory and reboots the IMC if the file is valid. If the file is not valid, the TimeProvider issues a

Deny response.

5. The COMPLD message appears after a successful transfer.

Upgrading the IOC

This section contains procedures for upgrading a shelf with a single IOC and for upgrading a shelf with redundant IOCs.

Upgrading Single IOCs

To upgrade the software in a single IOC, use the procedure in this section. Outputs from the TimeProvider will be interrupted for up to 30 minutes until the upgraded

IOC enters the Locked mode.

1. Log in to the TimeProvider with an Admin- or Security-level user id and password.

2. Save the contents of the IOC memory in the IMC by issuing the command:

CPY-MEM:::::IOC,IMC,IOC;

3. To start the download, issue the command

ACT-SWDL::IMC:TP1000;

The TimeProvider issues an In-Process response, the TL1 connection closes, and the TimeProvider waits to receive the upgrade software using the Ymodem protocol.

4. Use a Ymodem file transfer program such as SynCraft to transfer the upgrade software to the TimeProvider. You must start the transfer within 60 seconds or the

TimeProvider issues a Deny response. The new software is loaded into the IOC, after which it is rebooted and enters the Warm-up mode for up to 30 minutes.

097-58001-02 Revision C – August 2005 TimeProvider User’s Guide 183

Chapter 6 Maintaining and Troubleshooting the TimeProvider

Upgrading the Firmware

5. The COMPLD message appears after a successful transfer.

6. Restore the contents of the IOC memory from the IMC by issuing the command:

CPY-MEM:::::IMC,IOC,IOC;

Upgrading Redundant IOCs

To avoid output interruptions, the TimeProvider must be in the following state:

Two installed and communicating IOCs

Both IOCs are in the Locked mode

Both IOCs are In Service

Both IOCs are alarm-free

One IOC is Active

If any of these conditions are not present, then the outputs are interrupted for up to

30 minutes until the upgraded IOC enters the Locked mode.

To upgrade the software in both IOCs, use the following procedure:

1. Log in to the TimeProvider with an Admin- or Security-level user id and password.

2. Back up the contents of the IOC memory in the IMC by issuing the command:

CPY-MEM:::::IOC,IMC,IOC;

3. Start the download by issuing the command:

ACT-SWDL::IMC;

The TimeProvider issues an In-Process response, the TL1 connection closes, and the TimeProvider waits to receive the upgrade software using the Ymodem protocol.

4. Use a Ymodem file transfer program such as SynCraft to transfer the upgrade software to the TimeProvider. You must start the transfer within 60 seconds or the

TimeProvider issues a Deny response.

The active IOC (IOC1 for example) goes into Standby mode and the Standby

IOC (IOC2, in this example) goes into Active mode. The new software is loaded into IOC1, after which it is rebooted and enters the Warm-up mode for up to 30 minutes.

When IOC1 enters the Locked mode, it becomes the Active IOC again (IOC2 goes into Standby). The new software is loaded into IOC2, after which it is rebooted and enters the Warm-up mode for up to 30 minutes.

Chapter 6 Maintaining and Troubleshooting the TimeProvider

Returning the TimeProvider

5. The COMPLD message appears after a successful transfer.

Upgrading One IOC From the Other

To upgrade the software in one IOC to match the software in the other IOC, issue the command:

ACT-SWDL::IOCn:TP1000; where n = 1 or 2, and identifies the IOC that receives the software from the other IOC

You cannot upgrade the software in the Active IOC.
