Overview
Asynchronous Transfer Mode (ATM) networking is a technology that provides high bandwidth, low delay, packet-like switching and multiplexing techniques. Usable capacity is segmented into
53-byte, fixed-size cells, consisting of header and information fields, allocated to services on demand. Data is sent at irregular intervals, depending on networking availability, and no synchronizing or timing signals are required.
ATM technology was first used mostly in local area networks (LANs) but is increasingly being deployed for applications in wide area networks (WANs) and for applications involving both private and public network operations within the enterprise. ATM is a technology-enabling infrastructure that provides a global networking platform from which to connect all forms of communications applications. See Appendix A for a more detailed discussion of ATM technology.
The new Cell Exchange ATM products (CX-1500 and CX-1540) provide a flexible, modular, scaleable and cost effective “multi-access” solutions to WAN connectivity for emerging ATM networks. Multi-access means that these products allow users to transition into the new ATM technology at their own pace, while preserving their investment in the existing application infrastructure. These Cell Exchange products provide the user with an ATM Cell platform that serves on the “network edge” to multiplex and concentrate cell bearing (ATM), Frame Relay and legacy traffic (IP, Ethernet, TDM, asynchronous, bi-synchronous, SNA). These two systems are ideal for the wide range of ATM applications because of their flexible architecture and diversified interface designs. In addition, powerful ATM service capabilities result with maximum network efficiency when full traffic management and “Any-to-Any” connectivity are combined in their operation.
The CX-1500/CX-1540 Cell Exchange Systems
The CX-1500/CX-1540 Cell Exchange systems provide a versatile, scaleable, secure, and cost effective ATM cell platform. The Cell Exchange systems provide for expansion of today’s totally ubiquitous ATM networking concept by using ATM technology at lower bit rates, while at the same time continuing to make use of existing equipment.
The Cell Exchange system is designed on a modular hierarchy of functionality that allows the user to add features and functionality on a ‘need only’ basis. Thus, the user has the freedom to ‘size’ the equipment to the requirements of the application. The architecture of the Cell Exchange system is shown in Figure 1-1.

Figure 1-1. Cell Exchange System Architecture
The Cell Exchange system is a modular and scaleable ATM cell multiplexer that operates by using an ATM Cell Bus architecture. The system is physically constructed and integrated into a card frame sub-chassis. The Cell Exchange system comes standard with a shelf, power supply module and CPU module. Other modules can be integrated into the systems. The user has a variety of modules to choose from. Once a Cell Exchange system is populated with the modules chosen by the user for a particular application, all communications between modules is through the ATM Cell
Bus located on the backplane. The Cell Exchange uses a passive backplane design that includes the
ATM cell bus and dual power and ground tracks.
Modules and Services
The Cell Exchange system extends ATM networks to sites and applications that do not support native ATM interfaces.
*
This is accomplished through the use of various Interface Modules. A typical example is illustrated in Figure 1-2.
*
Non-ATM protocols are referred to as legacy systems in this manual.

Equipment Description
The Cell Exchange system is available in two physical modular designs that can integrate with a variety of ATM interface modules to provide the versatility and scalability needed to accommodate the rapidly growing ATM market, today and in the future. The CX-1500 system has a 15-slot chassis and the CX-1540 system a 4-slot chassis. Both chassis accommodate the same modules and come with a full complement of ‘common functionality’ modules, which are those that are needed to provide basic unit operation. These common modules are the CPU, Power Supply and
Station Clock modules. The CX-1500 comes standard with a chassis, passive backplane, power supply module(s) and operates from a standard AC source. For this system, the power supply module may be configured redundantly to further increase operational reliability. The CX-1540 does not have resources for a redundant Power Supply Module.
CX-1500
The CX-1500 is based on a passive backplane design, which allows all modules to be inserted from the front. The chassis has slots for 16 modules (including the CPU), plus two slots for power supply modules. It is designed for easy rack mounting in a standard 19-inch rack, but because it is fully enclosed, it may also be used in a desktop environment. Figure 1-3 shows a front-panel view of the CX-1500 system with redundant Power Supply Modules.

Chassis Specifications
Size: 5.25 inches high, 19 inches wide, 13 inches deep
Input Power: 90 to 230 VAC, 47 to 63 Hz, 2.0 amps
The Cell Exchange system chassis are based on a passive backplane design, which allows all modules to be inserted from the front. The power supply slot(s) is located in the left-most part of the chassis. In a chassis designed to accommodate more than one power supply module, a single module may be installed in either slot. The remaining slots may be populated with any type module. The CPU Module must be installed in slot 8 and the remaining slots be populated from the center outward.
Except for the Power Supply module, all Cell Exchange modules are designed in two sections: the
ATM Cell Bus control section, containing the Microprocessor and memory; and the module functionality section, which contains the components needed to perform the module’s unique function. All interface modules (exclusive of the CPU Module) have an identical ATM Cell Bus,
Microprocessor, and memory sections. For additional information on individual modules, see the
Chapter 3, “Modules.”
CX-1540
The CX-1540 is also based on a passive backplane design, which allows all modules to be inserted from the front. It has slots for 4 modules (including the CPU). The CPU must not be installed in
slot 1. The CX-1540 may be rack mounted, used on a desktop or, with optional hardware, wall
mounted. A typical front panel view of the CX-1540 is shown in Figure 1-4.

Power Distribution
Power distribution within the Cell Exchange 1500 systems is relatively simple. Standard AC power
(90 to 230 VAC, 47 to 63 Hz) is received at the backplane of the chassis and transferred via the power connector interface to the Power Supply Module. The Power Supply Module converts the
AC input to +5 VDC, which is then sent to a voltage regulator and the backplane bus.
Indicators
All indicators are located on the front panel of each module. Indicators for the various modules are described in the appropriate subsections in Chapter 3, “Modules.”
CPU Module
The CPU Module is designed around a Motorola 68340 microprocessor, and is used to control, configure, collect statistics, and provide all general management functionality within the unit. The
CPU module also provides master timing for the cell bus.
The CPU Module provides all configuration, control, and management functions for the Cell
Exchange systems from a local craft interface, remote dial-up modem management feature, or a
Simple Network Management Protocol (SNMP) interface. The CPU module controls all microprocessors/controllers on other Modules located in the same chassis, using the ATM bus message formatting structure. The CPU module (ATM bus) is also responsible for ATM Q.2931
signaling between the Cell Exchange CX-1500 and local/remote ATM switches.
Power Supply Module
The CX-1500 chassis may be equipped with one or two AC Power Supply Modules depending upon the degree of reliability the user is striving for. One Power Supply Module handles the full power load required for the number of interface modules placed in the chassis, with a reserve capacity of 40% above the maximum load capability. The Power Supply Modules feature a “solid state” switcher design. If two modules are installed, the modules are coupled to supply redundant power to the bus. The Power Supply Modules are designed to allow removal and replacement into a working unit without affecting active operational traffic (hot swap). Each Power Supply Module has its own power connector and cord.
The CX-1540 is equipped with a single AC Power Supply Module that is integrated with the chassis.

CXUG
7-31-98
Station Clock Module
The Station Clock (SCM) Interface Module allows the user to input and propagate an external clock source into the CX-1500 to be used as the internal reference clock for the unit. The SCM requires a balanced electrical input signal. The clock rate may be selected at a rate from 8 kHz to
50 MHz in 8 kHz steps.
Interface Modules
The Interface Modules are part of a broad group of modules that have been developed for the Cell
Exchange systems. Each Interface Module provides a specific service, as described in Chapter 3,
“Modules.”
Timing
The following describes the various timing systems and their functions that are resident in the
Synchrony Cell Exchange system. These timing systems are used specifically in ATM networks to support AAL1 (CBR) circuit emulation type traffic. There are four major timing systems in the
Cell Exchange system. These are:
•
System Timing
•
Data Bus Timing
•
Channel/Port Timing
•
External Timing
System Timing
System Timing is the term that is used when selecting a 'single' timing source to be used as the
Reference Timing Source by the Cell Exchange system. Only one timing source may be selected at a time. The Cell Exchange systems have the capability to select a pre-determined timing source that can be used by the rest of the Channel/Port Modules as a reference clock source. In Figure 1-5 the timing signal that may be chosen as the timing reference source is labeled REF/I (note that all of the REF/I lines are tri-stated for selection purposes which are microprocessor controlled).
Located on the same Figure, the timing signal that may be used as the timing reference is labeled
REF/O.

Data Bus Timing
A 25 MHz high-speed clock resident on the CPU module provides the Data Bus timing. Its primary use is to transfer ATM Cell traffic to and from installed modules in the Cell Exchange system chassis. Bus timing is only used on the bus; it is not used for any other purpose.
Channel/Port Timing
Channel/Port Timing are the various Timing reference signals that may selected on a particular interface module that resides in the Cell Exchange system. Normally that reference signal dictates how the timing on that particular channel/port will operate. The following timing options are available to various interface modules, although not all options are used on all modules:
•
Recovered Timing
•
On Board Timing
•
Reference Timing
•
Internal Timing
•
Dynamic Clock Tracking
Recovered Timing
In digital networks, the high-speed network interface circuit connected to the service provider’s network is normally used as the “master” timing reference. This digital interface is referenced in multiple geographic locations throughout the service provider’s network to a Stratum 1 reference source, which provides the network with a highly reliable and stable timing source. This timing source can be used as a timing source for the Cell Exchange system.
During initial configurations, the user can choose this timing source on most of the interface modules by selecting the interface circuit (A-B-C-D) connected to the service provider, and setting it as the reference timing source.
All designed modules have this capability to “recover” timing originating from the carrier circuit and phase-lock the 'reference clock' to it to produce various timing rates required by the Cell
Exchange system. If the circuit chosen to provide reference should fail, the Cell Exchange system will revert to the internal clock source as a secondary choice. All other modules may now use this timing as the timing reference.
On-Board Timing
On Board timing is the least stable of all timing sources and should only be used if no other timing source is available. On Board timing is provided as a source reference when testing the Cell
Exchange system in a 'back-to-back' mode. This timing source may be used by all the channel/ports on that particular module.
CXUG
7-31-98
1-9
This timing source may also be selected as of the 'reference' timing source. Selecting this timing source as the reference is accomplished in the same manner as for external timing, from the Timing
Configuration screen at the craft interface. Lower speed circuits may use this timing reference as a primary clocking source.
Reference Timing
Reference timing may be used on all modules select the 'reference' timing to be used to transfer data in and out of the selected interface on that module.
Internal Timing
Internal Timing is the clock that is resident on the CPU module and is presented to all the modules as an alternative timing selection. Internal Timing is also used for the 'fall-back' timing source in the case where the selected timing source failed in which case the 'fall-back' clock would then take its place until it is restored.
Dynamic Clock Timing
Dynamic Clock Timing is ONLY used on the DSL, QSL, and HSL Modules; no other modules have this feature. Dynamic Clock Timing derives timing from the clock that was inserted at the
'far-end' of the circuit. In Dynamic Clock timing the received cell data is buffered and continuously tracked. The tracking information is then processed by the on board CPU and used to control a
VCXO. The output of the VCXO is then used to shape the timing that is produced to clock the clear data out of the module to the terminal equipment.
NOTE:
When using any of the above clock sources as timing for a CBR-type emulation circuit, it is imperative that BOTH ends of the circuit are timed from the same source, and that they are synchronous with one another. If this is not done, transmit and receive timing will “slip” as the two clocks drift past one another.
External Timing
External Timing may be inserted into the Cell Exchange system by using the Station Clock Module
(SCM). External Timing is a source of timing derived from a customer who has a highly reliable and stable timing source apparatus, such as (LORAN or GPS) being used as a Master Station
Clock. The Master Station clock timing signal can then be injected into a Cell Exchange system and be used as the master timing source for all modules in either of these systems. From the craft interface, the user can select the SCM module as the source by entering the Timing Configuration screen and choosing the appropriate command. Lower speed circuits may use this timing reference for a primary clocking source.

System Cooling
System cooling is accommodated through normal ventilation. No special cooling is required under most environmental conditions when the unit is lightly populated. Under severe operating conditions, such as extremely high ambient temperatures or high concentrations of dust, circulation aids, such as stacking fan units, may be required. A stacking fan arrangement is shown in Figure
1-6.
PRECAUTION: If more than half of the slots in the CX-1500 Cell
Exchange system are populated, overheating may occur if ventilation fans are not installed.

Installation
Site Preparation
Minimal site preparation is required for the Cell Exchange system. They are easily mounted into a standard 19-inch rack.
Equipment Installation
Unpacking
The Cell Exchange system is shipped in cartons with adequate packing material to protect them from damage due to shock and vibration. Upon receipt of either system, inspect the condition of the carton for obvious damage. After opening, inspect the equipment for signs of damage, and inventory the equipment against the enclosed packing list. Notify the carrier and TimePlex immediately if there is any damage or shortages.
Required Tools and Equipment
There are no special tools or equipment required for installation of the Cell Exchange system.
Chassis Installation Procedures
Installing a Cell Exchange system chassis into the rack is simply a matter of selecting a mounting position with adequate room and ventilation for the Cell Exchange. A Cell Exchange system should have at least the space of open one rack unit (1-3/4 inches) above and below to provide unrestricted airflow to the venting ports in the chassis.
Once the chassis is mounted on the tray (slides), push it back into the rack until the ears on each side of the front panel contact the rack. Secure the chassis to the rack with 4 screws.
CXUG

Grounding Requirements
Once the chassis is installed, ground the installation by attaching a grounding strap (not supplied) between the common equipment rack ground and the grounding lug located on the backplane.
WARNING: ALWAYS ENSURE THAT THE CELL EXCHANGE
SYSTEM IS PROPERLY GROUNDED BEFORE
COMMENCING OPERATIONS. INJURY TO PERSONNEL
AND DAMAGE TO THE EQUIPMENT COULD RESULT IF
THIS PRECAUTION IS NOT OBSERVED.
Power Connections
The Cell Exchange systems require AC input power in the range 90 - 230 VAC, 47 - 63 Hz.
Ensure that the available station power can meet this criteria. To make a power connection, plug one end of a power cord into the system receptacle on the backplane and the other end into the power source receptacle. Figure 2-1 shows the AC module (receptacle) mounted on the rear of the
CX-1500 chassis. Figure 2-2 shows the CX-1540.

AC Power Supply Module
In the CX-1500 chassis, the power supply slots are located in the left-most part of either chassis. A single power supply module may be installed in either slot. The remaining slots may be populated with any type module. In the Model 1540 chassis, the single power supply module is installed internally.
Depending on the type of chassis, one or two power supply modules may be installed. One Power
Supply Module will handle the full power load required for the number of interface modules placed in the chassis, with a reserve capacity of 40% above the maximum load capability, although a second module may be installed (Model 1500 only) for enhanced reliability. The Power Supply
Modules feature a “solid state” switcher design. If two modules are installed, the modules are coupled to supply redundant power to the bus. The Power Supply Modules are designed to allow removal and replacement into a working unit without affecting active operational traffic (hot swap). Each Power Supply Module has its own AC power connector and cord.
AC power distribution within the CX-1500 CMC is relatively simple. Standard AC power is received at the backplane of the chassis and transferred via the power connector interface to the
Power Supply Module. The Power Supply Module converts the AC input to +5 VDC for transistor-transistor logic (TTL) use, then sends it to a voltage regulator and the backplane bus.
The voltage regulator reduces the +5 VDC input to a +1.3 VDC output for Gunning Transistor
Logic (GTL) use. There are three signal components to the DC power output: +5 VDC (TTL),
+1.3 VDC (GTL), and ground. A functional block diagram of the AC power supply module is shown in Figure 3-4.

Channel groups are configured as either voice or data. For channels configured as data, the STL sets up “clear channel” (64KHz) connections. For voice connections, the STL enables in-band
(“robbed bit”) signaling to pass through the network (Figure 3-20).
The user defines the various voice and data channel groupings via the STL interface configuration menu described in the configuration chapter. Each channel group consists of one or more channels.
The channels can be either contiguous or non-contiguous.

All 24 T1 channels mapped to one VPI/VCI pair
Figure 3-22. Channel Mapping
For STL-to-STL connections, the actual channel numbers of each group may differ at each end as long as each group contains the same number of channels. The ordering of channels passed from the source channel group to the destination channel group is always preserved. In other words, the first channel of the destination receives the data from the first channel of the source; the second channel of the destination receives the data from the second channel of the source, and so on.
STL Operation
Interface Loopback
Any STL interface can be looped back via the loopback option of the diagnostics menu. When loopback is enabled, the STL configures the interface for remote loopback (to connected equipment) as well as framer loopback (all T1 transmit data is looped back to the receiver).
STL to T1 Cell Bearing Connections
[Note: For connections between STL channel groups and a T1 cell bearing interface, the total number of T1 channels must not exceed 20 channels. This is due to overhead required by ATM. If more than 20 channels are connected to T1 cell bearing interface, cells are discarded. The result of attempting to connect more than 20 channels is a significant loss of signal quality across all channels.]
Idle Channel Data Insertion
For channels configured as idle channels (not associated with any group), the STL inserts idle data according to the interface configuration settings.
When the idle channel conditioning is configured as “Data Idle,” the values inserted are:
•
0x7F (binary 01111111) if “Idle (UAC)” is selected as the trunk conditioning data code
CXUG
7-31-98
3-27
•
0x1A (binary 00011010) if “MUX-OOS” is selected as the trunk conditioning data code
When the idle channel conditioning is configured as “Voice Idle” the idle values inserted are:
•
0xFF (all ones) if “Idle(0)/Busy(1)” is selected for trunk conditioning signaling
•
0x00 (all zeroes) if “Busy(1)/Idle(0)” is selected for trunk conditioning signaling
Trunk Conditioning Logic
Trunk conditioning attempts to minimize the impact that link failures can have on connected equipment by inserting data and signaling into each of the affected channels according to the currently configured trunk conditioning parameters. Figure 3-23 shows a typical case of trunk conditioning.

Figure 3-23. Trunk Conditioning
The STL initiates trunk conditioning whenever 1) connections are disabled or 2) received cell loss occurs for 3 seconds. Trunk conditioning is applied in the outbound direction (toward the connected equipment). Trunk conditioning is applied only on the affected channels.
For data channels, trunk conditioning simply inserts the idle data into the affected channels.
For voice channels, idle data insertion is applied after trunk conditioning first toggles the signaling bits as follows:
•
All zeroes (2.5 sec) followed by all ones (2.5 sec) when “Idle (0)/Busy (1)” is selected for trunk conditioning signaling.

T1 Signaling
As mentioned previously, the STL utilizes an AAL1 Segmentation And Reassembly (SAR) processor to pass the T1 data to and from the ATM network. For channel groups configured as voice, the STL directs the SAR to pass T1 signaling bits to and from the ATM network as well.
In the inbound direction (from a T1 interface into the ATM network), the SAR extracts signaling bits for each T1 channel and combines them into a single cell (separate from the actual data) for transmission through the ATM network. In the outbound direction (from the ATM network to a
T1 interface), the SAR extracts the signaling bits from these “signaling only” cells and inserts them into the correct T1 channels. This scheme allows signaling to be passed even if the T1 framing formats of the source and destination T1 interfaces differ.
ESF provides four signaling bits (the A, B, C, and D bits) while SF provides only two (the A and B bits). If a voice connection is configured between a channel group of a T1 ESF interface and a channel group of a T1 SF interface, signaling is affected as follows:
•
ESF inbound signaling bits A and B are mapped to SF outbound bits A and B, respectively
•
ESF inbound signaling bits C and D are lost since SF defines only two signaling bits
•
SF inbound signaling bit A values are mapped to two outbound ESF signaling bits A and C
•
SF inbound signaling bit B values are mapped to two outbound ESF signaling bits B and D

Operation
Initial Startup
On startup, the Cell Exchange will run through a short set of diagnostics, check for range errors in the current system configuration settings, and install the current system configuration (or the default configuration if range errors were detected).
Local Management Station
The Cell Exchange can be configured via a local VT100 emulation device (PC) connected via a null modem cable (See Appendix B for a description of the null modem cable.). Plug one end of the null modem cable into the PC serial port and the other into the port on the front of the CPU Module as shown in Figure 4-1.

It is important that the emulation package is VT100 compatible, as ProComm or Windows terminal emulation software. The configuration environment makes use of attributes that are not always correctly emulated. The Cell Exchange will not be affected by missing reverse video in the display, but it can be tiring for the operator. Setup instructions for two terminal emulation

Figure 4-2. Typical Logon Screen
Initial Logon
To access the Cell Exchange for configuration or software setup, the operator must first complete the logon procedures. The management system requires operators to logon with a password for the level of access desired. There is one password assigned to each access level. Passwords are assigned and controlled by the local system administrator.
If the logon screen is not displayed, or only partially displayed, refresh the screen by pressing
<ENTER> at the password entry prompt. Once the logon screen has repainted, the normal logon process can continue.
To logon:
1.
Power up the Local Management Station.
2.
Once the LMS has completed its internal startup procedures, call up the logon screen (see above).
3.
Follow the prompts on the screen.
4.
The default password is “admin.”
NOTE:
Once logged on, it is strongly recommended that the password be
changed as described in section "Changing Passwords.”
Logon Access Levels
Since various personnel will use the Cell Exchange, the management system allows three different levels of access. The following paragraphs describe the levels and the degree of access associated with each level.
Maintenance User - Able to login to view status and alarm conditions.
CXUG
7-31-98

Management User - Able to login to modify the configuration of the system in addition to maintenance user functions.
System Administrator - Able to login to set or change passwords in addition to all management and maintenance user functions.
Changing Passwords
Occasionally the system administrator or other authorized person may have to change passwords, due to the departure of personnel, compromise of the existing passwords, or some other reason. To change a password, select the Passwords command from the Configure menu. This will bring up the screen shown in Figure 4-3. Default passwords for each access level are shown.

Figure 4-4. Main Menu Screen
The menu name section is self-explanatory. The menu-specific section provides information or command selections relative to the menu that has been selected.
The prompt line is a user help function, containing information about the commands available for selection and the outcome of the selection. A prompt message will appear to show the user what information should be entered, or which key should be pressed, depending on the location of the cursor or the command selected.
The prompt line will also display alarm messages. When an alarm condition occurs or goes away, a brief message will be displayed. If multiple alarms occur, they will be queued and each message will be displayed for a very short time. When the last alarm message has timed out, the prompt line will revert to the help function.
The status line displays the current local time, the screen or menu name, alarm status, location name, and menu escape instructions where:
•
Time is displayed in 24-hour clock format (i.e., 2:30 PM is displayed as 14:30).
•
The screen/menu name area gives an indication of the path taken from the Main menu to the currently displayed screen. A colon is used to separate each element of the path.
•
The alarm status area tells the user if any alarms currently exist. If an alarm exists, the string
“**ALARM**” will be displayed. If no alarm exists, this area will be blank.
•
The location name area displays the user-assigned location name for each system.
•
The menu escape area displays the command required to exit the current screen. At the Main menu, the string “Q to Logout” is displayed. At any other menu or screen, the string “ESC-
ESC = Previous” is displayed.
Menu Selection
Within the Menu screen, the operator can move between menus by using the arrow keys or by
“quick key.” To use the arrows, simply press one of the left or right arrow keys. The menu selection will move left or right, and the new selection will highlight by displaying the menu name in reverse video and opening its command selections (drop down menu). If the current menu is the
CXUG
7-31-98
4-5
left-most menu and the left arrow is pressed, the display will “wrap” to the right-most selection.
The reverse is also true.
To use the “quick key” approach, press the key of the highlighted letter in each menu name.
Command Operation
From the Menu screen, the operator must perform the following steps to execute a command:
1.
Select the desired menu as the current menu.
2.
Use the arrow key or “quick key” to select the desired command.
3.
Select the command for execution by pressing <ENTER> or <F2> as shown on the prompt line.
Once a command is selected, it will be displayed in reverse video. To execute the command, simply press <ENTER>. The Command screen will now be displayed.
Moving around between commands is very similar to the menus, using the up and down arrow keys or a “quick key.” Using the arrow keys works exactly the same as for the menus, including the capability to wrap from top to bottom or vice versa. To use the “quick key,” press the key of the highlighted character in the command name.
Command Parameter Entry
Once a command is selected for execution, the operator will be prompted for all parameters associated with that command. For each required parameter, an entry area will be provided along with a prompt on the prompt line explaining the type of data required. As each parameter field is displayed, a default is provided. To select the default parameter, press the <ENTER> key before pressing any other key. Whenever possible, parameter selections will be made by toggle selections using the space key. This provides the operator with a consistent, user-friendly interface, and helps to limit out of range parameters. If numeric or ASCII text is required, the prompt line will show the valid range or number of ASCII characters allowed.
Regardless of the type of parameter, the entry process is ended by pressing the <ENTER> key. As each parameter is entered, validation checks are performed. If the entry is invalid, an error indication will be displayed on the status line. When the operator acknowledges the error by pressing the <ENTER> key, he/she will be prompted to enter a valid response before advancing to the next field. After a valid parameter has been entered, it will remain on the screen (if possible) until all parameters have been entered.
Keystroke Correction
To correct keystroke errors during command parameter entry, use the backspace key to erase the error, then reenter the correct information.
4-6
CXUG
7-31-98
Abort Command Key
The command parameter entry process can be ended at any time by pressing the <ESC> key twice
(<ESC><ESC>). This action will cancel command execution and return to the Menu screen.
Command Response
Commands executed by the Cell Exchange generally fall into two categories: commands that perform some process and commands that return status information. Commands that perform a process will usually return a completion code. This code is mapped into a completion status string that will be displayed on the status line. If an error is encountered during execution, the completion status string will be displayed in reverse video on the status line. If the command is executed successfully, the status string will be displayed in normal video.
Commands returning status information will only display a status string on the status line if an error occurred during execution. If execution is successful, the retrieved status information will be displayed in the command parameter window.

From the Hyper Terminal menu, select Transfer, then Capture Text. Hyper Terminal will prompt for the name of the file in which the text will be stored.
NOTE:
It is very important to enter a NEW filename each time the database
is saved. If an old filename is used, the capture text operation will append the text to the file instead of overwriting its contents, and subsequent database restore operations will fail.
Once the new filename is entered, click Start and hit the <ENTER> key or F1 to send the contents of the database to the local management station. When the transfer is complete, the screen is cleared and the following prompt is displayed in the prompt line.
Select Transfer: Capture text: Stop then press ESC-ESC to exit
After the Capture Text is stopped, the save operation is complete and pressing ESC-ESC returns to the Main Menu.
Restore DB - This menu allows the user to restore the database from a previously saved file.
Selecting this menu item brings up the screen shown in Figure 4-13.

Figure 4-13. Restore Database Window from Diagnostics Menu
Pressing the <F1> or <ENTER> key will begin the operation. The prompt line will change to
Select Transfer: Send Text File, enter the file name, and click Open
Once the Transfer/Send Text File is selected, the restore operation will begin. (Note that the Send
File menu option cannot be used for the Database Restore function.) Database restoration will take from about 10 seconds to about 1 minute, depending on the contents of the file. During this operation, no feedback is provided to the user.
When the transfer is completed, the Cell Exchange will be rebooted to ensure that any needed database conversion will be performed.
CXUG
7-31-98
If an error is detected during the Database Restore operation, the database will be completely cleared. Errors can arise from any of the following conditions:
•
Checksum error (each database file contains a checksum over the data).
•
Invalid database file format detected.
•
Database version not supported.
Alarms
Alarm messages are displayed on the prompt line. When an alarm condition occurs or clears, a brief message appears, lasting about 5 seconds. At the same time, the string “**ALARM**” appears in the status line. This string will remain until all alarms are cleared. If multiple alarms occur simultaneously, the alarms will be queued up, and each alarm message will only be displayed for about 1/2 second. The last message in the queue will be displayed for the full 5 seconds, assuming no new alarms occur. When the last alarm message has been displayed and has timed out, the prompt line will revert to its user help display.
An alarm message has priority over other prompt line messages. Therefore, if an alarm message is being displayed, and the user moves the cursor, the alarm message will remain for the full 5 seconds before displaying the help prompt for the new cursor position.
Module Statistics
The Cell Exchange system collects and displays performance statistics for each of its installed modules. To view the statistics for a given interface module, select Module Status from the View menu. The window shown in Figure 4-14 will appear.

Configuration
The configuration parameters for the Cell Exchange systems are stored on each module in batterybacked memory. This means that the configuration will remain unchanged even if power is removed from the unit. When power is restored, all configuration parameters previously set still reside in memory and the system will return to that configuration.
Initial configuration is normally accomplished in four steps:
1.
Set location name.
2.
Configure physical interfaces.
3.
Select system timing source.
4.
Configure connections.
These steps are further explained in the following paragraphs.

7.
Tab to the Priority field and select the queuing priority for the destination interface. This is a toggle field, pressing the <SPACE> bar will move between the selections: high, medium, or low priority for each VPI/VCI. The queuing priority setting may be used to minimize cell delay variation of CBR traffic, or to prioritize traffic on “over subscribed” circuits.
As traffic enters the CMC, each cell is assigned a priority based on the setting selected for the
VPI/VCI. Any type traffic (CBR, VBR, or ABR) may be assigned any priority. Although normally CBR traffic would be assigned high priority, other types of traffic could be set to higher priority and CBR to lower, as desired. As traffic exits the CMC, it does so via the assigned priority queue for that traffic. Queuing takes place on the output port.

Structured T-1 Legacy Module Configuration
Configuring STL Interfaces
To configure a new STL interface, follow the steps previously described in “Configuration
Physical Interfaces” to enter the name, the interface type (Structured T1), the slot, and the physical interface (A-H). Press F2 to enter the STL configuration menu. Figure 5-21 shows the STL configuration menu with all fields set to the default values. Here, the user is configuring interface B of the STL card in slot 14. The cursor is positioned on the Framing field (default is ESF) and the user is being prompted to select the framing mode. To configure the desired framing, the user enters the space bar to “toggle” the selection from ESF to SF.

Configuring Channel Groups
The STL interface configuration menu provides a channel assignment (data entry) field for each of the 24 T1 channels. Whenever the cursor is positioned in one of the channel assignment fields, the user is prompted as follows:
Channel assignment: Valid choices: I (idle), D1-D24 (data), V1-
V24 (voice)
To configure a channel group, choose a unique channel group ID and enter it into each of the channel assignment fields of the group. Channel group IDs for data channels (64 kHz clear channel) always begin with “D” and channel group IDs for voice channels (signaling enabled) begin with “V.” Only one ID can be assigned to a particular channel. An idle channel (a channel that does not belong to a group) is configured by entering an “I” in the channel assignment field.
As shown in the Figure 5-21, all channels are initially idle when a new interface is configured.
As mentioned previously, the channels comprising a group may be contiguous or noncontiguous.
The following figure depicts two channel groups V7 and D1. Channel group V7 consists of 3 noncontiguous channels, and channel group D1 consists of 3 contiguous channels.
When the cursor is positioned in the channel assignment field of a data channel, the total bandwidth of the data channel group is displayed in units of kHz. In the example below, channel group D1 provides a total bandwidth of 192 kHz.
T1 Transmit Clock Configuration
For each configured STL interface, one of four possible T1 transmit clock sources must be selected in the interface configuration menu:
•
Recovered (the default)
•
Internal
•
Ref Clock
•
On Board
Recovered means the T1 transmit clock is derived from the received T1 signal.
Internal means the T1 transmit clock is supplied by the main CPU board.
Ref Clock means the T1 transmit clock is supplied by the currently configured reference clock source, see “Setting System Timing.” Note that an STL interface can be selected as the reference clock source for the system.
On Board means the T1 transmit clock is supplied by the STL’s on board clock source.
It is important to note that all STL interfaces that are not configured to use recovered T1 transmit clock must share the same T1 transmit clock configuration. For example, selecting Reference for one interface automatically changes the clock configuration of all of the interfaces that are not configured for recovered clock.

Configuring Connections
STL connections are configured via the Connection Management menus, see “Configuring
Interface Connections.” Configuring connections to and from STL interfaces is very similar to configuring other connections. For STL connections, however, the user selects one of the channel groups instead of entering a VPI/VCI pair.
STL to Cell Bearing Interface Connections
An STL-to-Cell-Bearing connection configuration is illustrated in Figure 5-22, below. Here, a bidirectional connection is about to be enabled between a STL interface (channel group V14) and a cell-bearing interface such as an OC3 (VPI 2 and VCI 12). The channel group selection “V14/3” means that the channel group ID is V14 and is comprised of 3 channels. To select the desired channel group, the user positions the cursor in the channel group selection column (under the
“Chan” column) and presses the space bar to toggle through the configured channel groups. In this example, the name associated with the connection is “German PBX200.”

Troubleshooting
General Troubleshooting Procedures
If the Cell Exchange system does not appear to be working properly, connect a VT100 terminal to the CPU module and enter the local management system (See Chapter 4).
If you think a cable is not working, check to ensure the cables are correctly attached and not crosswired. Check to ensure that the cable is of the correct type. In the case of an optical connection, make sure the cable is single mode or multimode, as appropriate to the application.
Power Supply Module
If the red “FAIL” LED illuminates on a Power Supply module, there is a possibility that module has failed. Here are a few quick checks to verify the status of the module.
1.
If there is only one Power Supply Module installed, a failed module will shut down the Cell
Exchange system.
a.
If the “FAIL” LED is illuminated and the Cell Exchange system is still operational, the power supply is OK, but there is a malfunction in the LED circuitry. The module should be replaced as soon as is practicable.
b.
If the Cell Exchange system is shut down, but the front panel of the power supply module is blank, AC input to the module has been lost or the fuse is blown.
2.
If there is a redundant power supply installation, the backup power supply will automatically assume the load. Check the front panel LEDs for one of the following indications: a.
If the red “FAIL” LED is illuminated, the power supply module has failed. (Since the green “POWER” LED only indicates that +5 VDC is being read at the buss, the LED may be illuminated even though the power supply has failed.) b.
If the front panel of the power supply module is blank, AC input to the module has been lost or the fuse is blown.
CPU Module
If the red “FAIL” LED illuminates on a CPU module, the module has possibly failed.
CXUG
7-31-98
6-1
1.
In a single CPU installation, a failed CPU module may not be immediately evident because it only affects cell buss timing and configuration. Over a short period of time, however, performance of the Cell Exchange system will degrade.
2.
In a dual CPU configuration, if one module fails, the other will automatically take over. This will be indicated by the illumination of the “ACTIVE” LED. If the primary CPU module has in fact failed, its “ACTIVE” LED should extinguish, and the secondary module’s “ACTIVE”
LED should illuminate.
Other Modules
Information on the front panel indicators for other Cell Exchange system modules is provided in
Chapter 3, Modules. If any module indicator is not indicating normal operation for that module, the module may be defective.
Alarms
An alarm is any out of parameter condition detected during Cell Exchange operation. If such a condition is detected, an alarm message is generated and placed in the alarm queue, and an alarm indicator is displayed on the status line. The alarm indicator provides the operator with an indication that an alarm has been generated since the last time the current list of alarms was viewed. This serves as an alarm acknowledgment mechanism for the operator.
The operator can view the current list of alarms held in the alarm queue by selecting the View menu and Alarm Log command. Upon execution, the alarm indicator being displayed is removed from the status line and the list of alarm messages is displayed in the alarm window. The current alarm is displayed in reverse video.
Alarms and their meaning are described in Table 6-1.

Replacement Procedures
This section provides information for repair and replacement of failed modules on the Cell
Exchange system. The basic maintenance concept for the Cell Exchange system is limited to onequipment repair. Since the Cell Exchange system is modular in design, it lends itself readily to logical and straightforward maintenance procedures consisting of the removal and replacement of components.
Electrostatic Discharge (ESD) Anti-Static Procedure
When performing any maintenance action on the Cell Exchange system, observe the following procedures:
1.
Ensure that the Cell Exchange system is properly grounded.
2.
Connect an ESD wrist strap to the same ground as the Cell Exchange system.
3.
Put the wrist strap on before handling any module or the chassis of the Cell Exchange system.
4.
Use protective ESD bags to handle, store, or ship Cell exchange system components.
5.
If the maintenance or replacement action requires removing a module, do the following:
•
Remove the replacement module from its protective ESD bag and lay it on the bag.
•
Remove the defective module and lay it on another ESD bag or on the same bag.
6.
When maintenance or replacement is complete, remove the wrist strap and disconnect it from ground.
Removing and Replacing Chassis
To remove the Cell Exchange system from the rack:
1.
Turn the power switch(es) to the OFF (0) position.
2.
Unplug the power cord(s) from the power source receptacle and rear panel connector.
3.
Remove the grounding strap from the grounding lug on the rear panel (backplane).
4.
Remove the screws attaching the chassis to the equipment rack.
5.
Slide the chassis out of the rack.
CXUG
7-31-98
7-1
To replace the chassis:
1.
Slide the new chassis into the rack.
2.
Replace the screws attaching the chassis to the equipment rack.
3.
Attach the grounding strap to the grounding lug on the rear panel.
4.
Plug the power cord(s) into the rear panel connector and power source receptacle.
5.
Turn the power switch(es) to the ON (1) position.
PRECAUTION: Secure the AC power cable to the AC connector on the rear panel before connecting the cable to the AC power source. Failure to comply with this procedure may result in electrical shock.
Removing and Replacing Modules
All modules in the Cell Exchange system may be removed and replaced without removing electrical power from the chassis (hot swap). Figure 7-1 represents the removal of a Power Supply Module, but all Cell Exchange system modules are similar.

Asynchronous Transfer Mode
Asynchronous Transfer Mode (ATM) technology was developed for the high-speed transfer of voice, video, and data through private networks and across public networks. ATM technology provides a way of linking a wide range of devices (from telephones to computers) using one seamless network. It removes the distinction between local area and wide area networks, integrating them into one network. ATM can integrate all traffic types, eliminating parallel networks supporting different applications (like voice and data) and multiple links to the same location. It supports both bursty data and delay sensitive traffic.
ATM is a cell-switching and multiplexing technology that combines the benefits of circuit switching (constant transmission delay and guaranteed capacity) with those of packet switching
(flexibility and efficiency for intermittent traffic). ATM uses an unchannelized bandwidth approach for traffic transport. Like X.25 and Frame Relay, ATM defines the interface between the user equipment (such as workstations and routers) and the network. This interface is referred to as the
User-Network Interface (UNI).
The asynchronous in ATM refers to the way in which ATM achieves its unchannelized bandwidth allocation. ATM differs from synchronous transfer mode methods, where time-division multiplexing (TDM) techniques are employed to pre-assign users to time slots. ATM time slots are made available on demand, with information identifying the source of the transmission contained in the header of each ATM cell. Relative to ATM, TDM is inefficient because a time slot is wasted when a station has nothing to transmit. Also, when a station has more information to transmit that can fit into its allotted time slots, only part of the information can be sent at that time even though other time slots may be empty. With ATM, a station can send cells whenever necessary.
ATM networks allow for strict quality-of-service guarantees because network resources are allocated on a per connection basis. Cell sequence integrity is maintained because routing decisions are made only at connection establishment time.
ATM Networks
ATM networks are connection-oriented, where virtual connections are established between endsystems, and cells are switched according to connection identifiers. The network architecture uses unchannelized network transports. Since there are no physical channels to distinguish the traffic in an ATM network, logical connections are established. Instead of voice and video channels, ATM has voice and video connections. These logical connections are established and maintained by means of a two-part identifier structure: the virtual path and the virtual channel.
A virtual path (VP) is a concept used to describe the transport of cells belonging to a set of virtual channels. Each VP is assigned a unique identification value, called the virtual path identifier (VPI).
CXUG
7-31-98
A-1
A virtual channel (VC) is a concept used to describe the transport of ATM cells associated by a unique identification value, called the virtual channel identifier (VCI). A VP is a logical grouping of VCs that allows an ATM switch to perform operations on groups of virtual circuits.
ATM switches use the VPI and VCI fields located in the cell header to identify the next network segment that a cell needs to transit on its way to its final destination. A virtual channel is equivalent to a virtual circuit; both terms describe a logical connection between the two ends of a communications connection. As a result, ATM offers a private switched connection for each user.
The concept of virtual circuit simplifies routing once a path is established, and allows components within the network to simply distinguish among different traffic flows for purposes of admission, congestion control, and security. Multiplexing and switching in ATM are always done on VPs first and then on VCs.
ATM Cell
ATM uses very large-scale integration (VLSI) technology to segment data at high speeds into units called cells. Cells transit ATM networks by passing through switches, which analyze information in the header to switch the cell to the appropriate output port. The cell moves from switch to switch as it works its way to its destination.
ATM technology is based entirely on cell structure. The ATM cell is a 53-byte fixed length cell consisting of a 48-byte information field (cell payload) to carry user or network information, and a
5-byte header that contains information used to route the cell to its destination (Figure A-1). The header and cell payload remain constant at both the user-network interface (UNI) and networknetwork interface (NNI). Cells are assigned on demand, depending upon the source activity and available resources. Unlike earlier LAN or WAN techniques, ATM cells can be sent over a wider variety of media types (e.g., copper wire or fiber optic cable) and a wider range of transmission speeds (e.g., up to 622 Mbps).

Figure A-1. ATM Cell Structure
The main function of an ATM switch is to receive cells on one port and switch those cells to the proper output port based on the VPI and VCI values of the cell. This switching is dictated by a switching table that maps input ports to output ports based on the values of the VPI and VCI fields.
ATM Reference Model
The ATM transport network common to all services is structured into an ATM layer and a physical layer. Figure A-2 is a reference model that illustrates the organization of ATM functionality and the interrelationships between the layers of functionality.
In the ATM reference model, the ATM layer and the ATM adaptation layers are roughly analogous parts of the data link layer of the Open System Interconnection (OSI) reference model, and the ATM physical layer is analogous to the physical layer of the OSI reference model. The control plane is responsible for generating and managing signaling requests. The user plane is responsible for managing the transfer of data. Above the ATM adaptation layer are higher-layer protocols representing traditional transports and applications.

Physical Layer
The ATM physical layer controls the transmission and receipt of bits on the physical medium. It also keeps track of ATM cell boundaries and packages cells into the appropriate type of frame for the physical medium being used. ATM can use any physical medium capable of carrying ATM cells. Some existing standards that can carry ATM cells are SONET (Synchronous Optical
Network)/SDH, DS-3/E3, 100-Mbps local fiber (Fiber Distributed Data Interface [FDDI] physical layer), and 155-Mbps local fiber (Fiber Channel physical layer).
ATM Layer
The ATM layer is fully independent of the physical medium (physical layer) used to transport the
ATM cells and applications it supports above the ATM layer. This allows a wide range of upperlayer services to be supported by a single transfer mode over multiple physical media. The result is not only an integrated data transfer but also the ability to support novel integrated applications.
The ATM layer is responsible for establishing connections and passing cells through the ATM network. To do this, it uses the information contained in the header of each ATM cell. The ATM layer maps network layer addresses to ATM addresses.
The primary function of the cell header is to identify cells that belong to a virtual channel (VC).
The ATM layer also supports a virtual path (VP), identified by the virtual path identifier (VPI).
The information field of a cell is transported transparently by the ATM layer. In addition, the
A-4
CXUG
7-31-98
ATM layer preserves the cell sequence integrity on a virtual channel connection. The ATM layer provides single bit error correction on the ATM header.
ATM Adaptation Layer
The ATM adaptation layer (AAL) translates between the larger service data units (SDUs) (for example, video streams and data packets) of upper-layer processes and ATM cells. Specifically, the ATM adaptation layer (AAL) receives packets from upper-level protocols (such as AppleTalk,
Internet Protocols [IP], and NetWare) and breaks them into the 48-byte segments that form the payload field of an ATM cell.
The primary function of the ATM adaptation layer (AAL) is to segment user data into ATM cells and to reassemble the ATM cells into user data at the destination end system. This layer can provide end-to-end error control, buffering, flow control, and multiplexing based on the applications requirements. The AAL is divided into 4 classes of service, as shown in Figure A-3.

Quality of Service
When an ATM end station connects to the ATM network, it is essentially making a contract with the network based on quality of service (QoS) parameters. This contract specifies an envelope that describes the intended traffic flow. This envelope specifies values for peak bandwidth, average sustained bandwidth, and burst size.
CXUG
7-31-98
A-5
It is the responsibility of the ATM device to adhere to the contract by means of traffic shaping.
Traffic shaping is the use of queues to constrain data bursts, limit peak data rate, and smooth jitter so that the traffic will fit within the promised envelope.
ATM switches have the option of using traffic policing to enforce the contract. The switch can measure the actual traffic flow and compare it against the agreed upon traffic envelope. If it finds that traffic is outside of the agreed upon parameters, the switch can set the Cell Loss Priority
(CLP) bit of the offending cells. Setting the CLP bit makes the cell eligible for discard, which means that the switch, or any other switch handling the cell, is allowed to drop the cell during periods of congestion.
Congestion control is a primary concern of ATM designers. For example, dropping just one cell that is part of a FDDI frame can result in the retransmission of 93 cells. Retransmission can lead to an exponential increase in congestion. As ATM switches drop individual cells from different packets, more packets are retransmitted, causing even more cells to be dropped.
