Radio Frequency Interference Statement
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in
a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio frequencies. Operation of this equipment
in a residential area is likely to cause harmful interference in which case the user will
be required to correct the interference at his own expense
.
Shielded cables must be used with this unit to ensure compliance with
Class A FCC limits.
Changes or modifications to this unit not expressly approved by
the party responsible for compliance could void the user's
authority to operate the equipment.

Canadian Equipment Limitations
Notice: The Canadian Industry and Science Canada label identifies certified equipment. This certification means that the equipment meets certain telecommunications
network protective, operational, and safety requirements. The Department does not
guarantee the equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must
also be installed using an acceptable method of connection. In some cases, the company’s inside wiring associated with a single line individual service may be extended
by means of a certified connector assembly (telephone extension cord). The customer
should be aware that compliance with the above limitations may not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user
to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of
the power utility, telephone lines and internal metallic water pipe system, if present,
are connected together. This precaution may be particularly important in rural areas.
Users should not attempt to make such connections themselves, but
should contract the appropriate electric inspection authority, or an
electrician, as appropriate.
The Load Number (LN) assigned to each terminal device denotes the percentage of
the total load to be connected to a telephone loop which is used by the device, to prevent overloading. The termination on a loop may consist of any combination of
devices subject only to the requirement that the total of the Load Numbers of all
devices does not exceed 100.

Introduction
PRODUCT OVERVIEW
The MX2800 STS-1 is a SONET multiplexer that consolidates T1
and E1 signals into an STS-1 signal. This unit provides a costeffective, versatile tool for combining independent T1s or E1s over
the same STS-1 carrier.
Embedded SNMP (simple network management protocol) and
Telnet are available through the modem port using SLIP/PPP or
through the 10BaseT ethernet port. Using the Management
Information Base II (MIB II), RFC 1595 standards, and an
ADTRAN enterprise MIB, the MX2800 STS-1 can be configured,
monitored, and diagnosed with standard SNMP network
management programs such as Hewlett Packard’s HP OpenView™
and Cabletron’s Spectrum™. In addition, the SysLog Host Daemon
allows remote monitoring, collecting, and logging of MX2800
STS-1 events in real time. This information can be useful during
installation setups and/or troubleshooting.
Complete configuration, diagnostics, and performance monitoring
are available through SNMP, Telnet, or a VT-100 terminal
interface. This connection can be made via ethernet, a local EIA232 link, or through the built-in V.34 modem (see the note at the
end of this section on page 1-2). The modem can dial-out a “cry for
help” for units located in unmanned facilities. The MX2800 STS-1
is designed for either desktop use or for installation in a 19-inch or
23-inch rack.

Chapter 1. Introduction
STS-1 OVERVIEW
The MX2800 STS-1 multiplexer delivers up to 28 T1s or 21 E1s via
the SONET Synchronous Transport Signal Level One (STS-1) at a
speed of 51.84 Mbps. This is a cost-effective way to provide T1/E1
signals without the need for costly and complex multi-level
multiplexing/demultiplexing as in an M13 multiplexer. The T1/E1
signals can be directly multiplexed into the SONET STS-1 signal,
allowing simplified add and drop functionality.
The MX2800 STS-1 multiplexer also implements VT hairpining
and VT cross-connect mapping. Any VT can be hairpinned back to
the STS-1 signal for dropping further down the SONET ring.
Cross-connect mapping permits a VT to be mapped to any of the 28
available physical ports.
STS-1 Framing
The STS-1 frame is organized as 9 rows by 90 columns of bytes.
This frame is transmitted row by row, from left to right, and with
the most significant bit (MSB) of each byte transmitted first. It is
defined to operate at the basic rate of 8 kHz or 125 microseconds
per frame, or 8,000 frames per second at a bit rate of 51.84 Mbps.
The frame is divided into two parts to physically segregate the
layers. The first 3 columns make up the transport overhead (TOH);
the remainder is the synchronous payload envelope (SPE). The
TOH has 3 rows for the section overhead (SOH) and 6 rows for the
line overhead (LOH). The SPE has one column for the path
overhead (POH). The remaining 86 columns are for payload data
(49.536 Mbps).
STS-1 Pointers
There are several mechanisms that allow for timing compensation
between the STS-1 and its low speed tributaries. The MX2800
STS-1 multiplexer uses pointer adjustments to achieve timing
61200659L1-1
MX2800 STS-1 User Manual
1-3
Chapter 1. Introduction
compensation. Pointer adjustments allow the synchronous payload
envelope (SPE) to float with respect to the SONET frame. The
pointer is contained in the H1 and H2 bytes of the line overhead
(LOH), and is a count of the number of bytes the J1 byte is away
from the H3 byte, not including the transport overhead. When
timing differences exist, dummy bytes are inserted into the SPE
without affecting data. The receiving end can recover the payload
since the pointer is adjusted to indicate where the payload overhead
(POH) starts.
Transport Overhead (TOH)
The first three columns are the TOH, which contains the overhead
bytes for the Section and Line layers. Section overhead is
comprised of 9 bytes and Line overhead is comprised of 18 bytes.
STS-1 Synchronous Payload Envelope (SPE)
The SPE has 87 columns and 9 rows of bytes for a total of 783
bytes. Column 1 contains the STS Path Overhead and has 9 bytes.
The remaining 774 bytes are available for payload.
Virtual Tributaries (VT)
The SPE is divided into seven virtual tributary groups, made up of
12 columns each. Smaller tributaries are multiplexed together to
form these groups. For example, there can be four VT1.5 tributaries
in a VT group or three VT2 tributaries. A VT1.5 tributary consists
of three columns per STS-1 frame and has a bit rate of 1.728 Mbps,
allowing transport of a T1 at 1.544 Mbps plus required overhead. A
VT2 uses four columns per STS-1 frame and has a bit rate of 2.304
Mbps, allowing transport of an E1 at 2.048 Mbps plus required
overhead.

Chapter 1. Introduction
Unit Timing
The MX2800 STS-1 multiplexer allows three timing methods. The
first is LOOP timed, in which the multiplexer derives timing from
the incoming STS-1 signal. A failure in this signal, such as a lossof-signal (LOS) or a loss-of-framing (LOF) will cause the unit to
enter HOLDOVER (HO) mode for the duration of the receive signal
defect. During HO, the unit will continue transmitting at the same
rate as the receive signal prior to entering its defect condition.
Stability of the transmit during HO is guaranteed to +/- 4.9 ppm
over 24 hours. The defect condition must be cleared before LOOP
time mode can be resumed.
The second mode of operation is FREE-RUNNING (FR) mode. In this
mode, an internal oscillator is used to generate transmit timing.
FREE-RUNNING mode provides a SONET minimum clock
specification of +/- 20 ppm.
The third timing operation mode is EXTERNAL. EXTERNAL timing
mode allows the MX2800 STS-1 to derive its transmit timing from
any one of the 28 DSX-1/E1 physical ports. The ports selected may
be data carrying ports. Two sources can be specified to provide
external timing: a primary and a secondary source. Failure of the
primary source (due to LOS or AIS) will cause the unit to switch to
the secondary source, if available. In the event that both the primary
and secondary sources are lost, the unit will enter HOLDOVER mode
as described previously. Holdover mode will be exited upon
recovery of at least one clock source.
SNMP
The MX2800 STS-1's embedded SNMP feature allows the unit to
be accessed and controlled by a network manager through the
10BaseT local area network (LAN) port. The MX2800 STS-1
61200659L1-1
MX2800 STS-1 User Manual

Chapter 1. Introduction
supports the MIB-II standard, RFC 1213, RFC 1595, and the
ADTRAN Enterprise Specific MIB.
MIB files are available at www.adtran.com.
The term SNMP broadly refers to the message protocols used to
exchange information between the network management system
(NMS) and the managed devices, as well as to the structure of
device management databases. SNMP has three basic components,
the network manager, the agent, and the MIB.
Network Manager
The network manager is a set of control programs that collect,
control, and present data pertinent to the operation of the network
devices. These programs reside on a network management station.
Agent
The agent is a control program that resides in every network device.
This program responds to queries and commands from the network
manager, returns requested information or invokes configuration
changes initiated by the manager, and sends unsolicited traps to the
manager.
MIB
A MIB is an industry standard presentation of all status and
configuration parameters supported by a network device.
TELNET
Telnet provides a password-protected, remote login facility to the
MX2800 STS-1 that allows a remote user to control the MX2800
STS-1 through the terminal menus. Only one Telnet session may be
active at a time.

TL1
Transaction Language 1 (TL1) is an ASCII based language that
supports both command-response and autonomous (NE) message
generation. Commonly, TL1 is used over a X.25 packet network
but is completely independent of any physical layer protocols. For
the MX2800 STS-1, TL1 is implemented as a Telnet session
running over either Ethernet or PPP. Only one TL1 Telnet
connection can be active at a time.

RACKMOUNT INSTALLATION
The MX2800 STS-1 can be mounted into a standard 19-inch or
23-inch equipment rack. Follow these steps to mount your unit into
a rack:
1. Prepare the MX2800 STS-1 mounting ears by scraping the
paint away from the mounting ears’ portion that makes contact
with the rack and the portion where the screw mounts into the
side of the MX2800 STS-1.
2. Install the mounting flanges on each side of the MX2800 STS-1
at one of the three available positions.
Be sure to install the flanges with the screws provided.
3. After the flanges have been installed, position the MX2800
STS-1 at the correct location within the rack and secure the
mounting flanges to the mounting rails of the rack.
4. Make all network, DTE, and power connections to the rear of
the unit. See Power Up on page 2-2 for more information on
making the DC power connection.
5. Using the 8-position modular to DB-9 female connector and the
8-position modular to 8-position modular cable, connect a
VT 100 terminal device to the CRAFT port on the front panel of
the unit.
Two MX2800 STS-1s may be stacked with no spacing between units.
ADTRAN recommends 1U (1.75") of separation above and below the
two stacked units. This spacing allows the unit to dissipate heat. The
design of the MX2800 STS-1 uses the chassis to distribute heat
generated by the unit's internal cards. This design allows the unit to
operate without a cooling fan, which increases its overall reliability.

The LAN port is an 8-pin modular connector that provides a
10BaseT ethernet LAN interface. This LAN interface is used for
SNMP and Telnet control.
Connect the LAN port to intra-building wiring only.
Modem Port
The MODEM port is an 8-pin modular jack that provides a telephone
line (POTS) connection for the internal V.34 modem.
The MX2800 STS-1 can be configured as a dial-in host and also as
a dial-out-on-Trap device (meaning the unit dials out to a specified
host to report error conditions).
Information regarding the built-in modem applies to the following list
of numbers: 4200659L1, L2, L3, and L4.
Noncritical and Critical Alarm Connectors
The alarm connectors connect to the three contacts of a Form C
type relay on the main board of the MX2800 STS-1. This relay is
activated any time the MX2800 STS-1 detects an alarm condition
on the STS-1 network interface. Both NC (normally closed) and NO
(normally open) contacts are provided.
Connect alarms to one of the three-position modular terminal lug
connectors (provided). These connectors make it easier to perform

Select NETWORK INTERFACE to access the network configuration
parameters (see Figure 3-3). Configure the MX2800 STS-1
network settings to match the STS-1 signal received from the
service provider.
Figure 3-3. Network Configuration Menu
STS-1 Configuration
Use the STS-1 CONFIGURATION selections described below to
configure the STS-1 network settings to match your application.
Line Length
Set the line length to reflect the physical length of the STS-1
network line. Set to LONG if the cabling distance is between
225-450 feet; set to SHORT if the distance is less than 225 feet.
Timing
Selects the source of timing used to derive the transmit signal. The
MX2800 STS-1 has three modes of timing operation: LOOP, FREERUN, and EXTERNAL. LOOP timing configures the unit to recover
clocking from the STS-1 receive signal. Loss of the STS-1 receive

signal or reception of AIS will cause the unit to enter hold-over
mode. The STS-1 receive signal must be valid for at least 10
seconds for the unit to exit hold-over mode and restore loop timing.
When the unit is configured for FREE-RUN timing mode, timing is
derived from a +/-20 ppm internal reference providing a SONET
Minimum Clock (SMC).
Setting the unit to EXTERNAL timing mode configures the unit to
derive clocking from one of the two external sources selected in the
PRI EXT. CLOCK and SEC EXT. CLOCK options. These two entries
select which of the 28 active T1/E1 ports will be used as the
external clock source. The external clock source may be disabled (if
only one source exists, or no external clock sources are desired). A
valid clock source is one on which neither LOS or AIS conditions
exist. The selected T1/E1 may be a data carrying tributary. When
both sources are configured, failure of one source will cause the
unit to switch to the other source (if it is a valid source). Failure of
both sources will cause the unit to enter hold-over mode. At least
one external clock source must be valid for at least 10 seconds for
the unit to exit hold-over mode and restore external clock timing.
Switching between PRImary and SECondary external clock sources
is non-reverting.
XCV Threshold
The XCV THRESHOLD (excessive code violations threshold) sets a
limit on code violations accepted by the unit before it switches
controller cards. If set to DISABLED, code violations will not cause
the unit to switch controller cards. The threshold limits are
described in the following chart:
3-4

Chapter 3. Configuration
Setting
The unit switches controller cards if...
1E-3
more than one out of every 1,000 bits received on the
STS-1 contains a code violation.
1E-4
more than one out of every 10,000 bits received on
the STS-1 contains a code violation.
1E-5
more than one out of every 100,000 bits received on
the STS-1 contains a code violation.
1E-6
more than one out of every 1,000,000 bits received on
the STS-1 contains a code violation.
VT Mode
The STS-1 can frame the 7 VT groups as either VT1.5 or VT2.
When set for VT1.5 (T1), all VT groups are set for VT1.5[TU=11]
at 1.728 Mbps and the ports are set for T1 at 1.544 Mbps. When set
for VT2 (E1), all the VT groups are set for VT2[TU-12] at
2.304 Mbps and the ports are set for E1 at 2.048 Mbps. When set
for VT2, the last 7 VTs, VT 22-28, become unavailable. All E1
ports are available for mapping.
Protection Configuration
The MX2800 STS-1 houses two controller cards for 1:1 protection
against hardware failure. The two cards can also provide network
protection, supporting two STS-1 circuits simultaneously. The
selections in this menu allow you to customize the unit’s protection
setup.
Active Controller
This field displays A or B, indicating the active controller card. This
setting can be used to force the controller cards to switch. For
example, if controller card A is active and you select B, a switchover occurs immediately.

Network Protection
Enable or disable the unit’s ability to automatically route
information to the backup STS-1 in the event of a primary STS-1
failure. With NETWORK PROTECTION set to ENABLED, all information
is automatically routed to the backup STS-1 in the event that the
primary STS-1 fails. When NETWORK PROTECTION is set to
DISABLED, the stand-by controller will be used to protect against
failures of the circuitry on the active controller.
When choosing a setting for NETWORK PROTECTION, there are many
cabling and network provisioning issues to consider. For configuration
examples of the different modes of protection, refer to
Chapter 7, Circuit and Network Redundancy.
Max. Switch Threshold
The value entered in this field determines the number of times per
hour the unit is allowed to switch between controller cards. If the
cards switch more than the MAX SWITCH THRESHOLD within one
hour, the unit issues a trap and stops switching cards for the next 24
hours. The default setting is 3 times an hour.
Min. Switching Period
After the unit switches controller cards, the number of seconds
entered in this field must pass before another card switch will be
allowed. The default setting is 10 seconds.

clock becomes invalid.
VT INTERFACE
The VT INTERFACE menu (shown in Figure 3-4 on page 3-7) allows
you to activate/deactivate individual T1s and E1s and to set their
line coding, length, loopback detection, circuit protection, and line
ID string. The T1/E1 code violation threshold is also configured
through this menu. Configuration selections are described in the
sections following Figure 3-4 on page 3-7.
A VT group can be divided into either three E1s or four T1s. Therefore,
when dealing with an E1 configuration, some of the fields in the VT
INTERFACE menus do not apply (and therefore display N/A).

VT/PORT LOOPBACKS
After you select the number that corresponds with the line you want
to test, the menu in Figure 6-2 appears. The number selected
(1-28) refers to the VT number. The Port (T1/E1) that will be tested
is the port mapped to the selected VT number. The sections
following the figure provide descriptions and illustrations of the
testing options. Select 1-DATA MODE to end a test in progress.

Tributary
A TRIBUTARY loopback loops the selected VT/Port back to the
network (STS-1). The T1/E1 is looped back through the STS-1
mapper. During this loopback, the corresponding DSX-1/E1 input
is overwritten by the outgoing DSX-1/E1 signal. See Figure 6-3 on
page 6-3 for an illustration of this test.

CSU Loopback
A CSU LOOPBACK enables the MX2800 STS-1 to generate a CSU
loop-up pattern (001001…) towards the T1 CSU attached to the
selected T1 line for six seconds. After six seconds have elapsed, the
pattern will cease and incoming network traffic will be passed
through to the CSU device. If the CSU device responded to the
CSU loop-up pattern, it will return all data back towards the
network. A loop-down pattern (0000100001….) will be generated
towards the CSU for six seconds when DATA MODE is selected.
When in CSU LOOPBACK, only the DATA MODE for the T1 under test
may be selected. Selecting any other option will result in an error
message being displayed.
CSU Loopback w/BERT
A CSU LOOPBACK W/BERT enables the MX2800 STS-1 to test the
local T1 loop to the CSU using the standard QRSS pseudo-random
bit sequence. When CSU LOOPBACK W/BERT is selected, the
MX2800 STS-1 will initiate a CSU loopback towards the CSU
attached to the selected T1 line similar to the CSU LOOPBACK test
above. Six seconds after starting the CSU loop-up pattern, the
MX2800 STS-1 will cease sending the CSU loop-up pattern and
begin sending an unframed 511 pattern towards the CSU. If the
CSU device responded to the CSU loop-up pattern, the
MX2800 STS-1 will check the incoming pattern for errors.
Additional menu items will appear to show the state of pattern
synchronization, error count, and a clear error count option (see
Figure 6-7 on page 6-6). Selecting DATA MODE will cease the
transmission of the QRSS pattern and start transmission of a loopdown pattern as previously described.

VT BERT
A VT BERT enables the MX2800 STS-1 to perform a “head-tohead” BERT test towards the STS-1 network. Selecting VT BERT
will replace all incoming T1/E1 traffic for the T1/E1 mapped to the
selected VT with an unframed QRSS pattern towards the network.
When VT BERT is selected, additional menu items will appear to
show the state of pattern synchronization, cumulative error count,
and a clear error count option. Selecting DATA MODE will cease
QRSS pattern generation and substitution of the incoming data
stream. See Figure 6-8 on page 6-7 for an illustration of this test.
When in VT BERT mode, only the DATA MODE option for the
VT/Port under test may be selected. Selecting any other option will
cause an error message to be displayed.

After you select STS-1 LOOPBACK, the menu in Figure 6-10
appears. The sections following the figure provide descriptions and
illustrations of the testing options. Select 1=DATA MODE to end a
test in progress.
Figure 6-10. STS-1 Diagnostics Menu
Line Network
LINE NETWORK performs a loop of the STS-1 back to the network.
This loopback occurs just prior to the HDB3/B8ZS decoder of the
LIU; therefore, any coding violations received by the STS-1 will be
inserted back into the network without modification. See Figure
6-11 on page 6-9 for an illustration of this text.
If a LINE NETWORK loopback is active when the MX2800 STS-1 is
operating in the FREE-RUN timing mode, the timing source for the
STS-1 is effectively removed from the circuit. Therefore, it is up to
the test equipment or network to provide STS-1 timing into the
circuit for the duration of the test.

Circuit and Network Redundancy
The MX2800 STS-1 provides backup measures of protection for
both circuit and network failure. The following sections describe
the three possible modes of operation:
•
•
•
Non-Redundant Mode, which offers no backup protection, is
described on page 7-2.
Circuit Failure Recovery Mode, which offers backup protection
in the event of controller card failure, is described on page 7-3.
Circuit and Network Failure Recovery Mode, which offers a
complete backup system for both card and network failure, is
described on page 7-4.
The descriptions given include illustrations and suggested
configuration settings. Please note that the settings may need
modification based on your network configuration.

NON-REDUNDANT MODE
In Non-Redundant Mode, the MX2800 STS-1 houses only one
controller card and only one network connection is available. There
is no failure protection. In the event of a failure, an alarm is initiated
and the front panel LEDs reflect the condition. See Figure 7-1 for
an illustration.

CIRCUIT FAILURE RECOVERY MODE
In Circuit Failure Recovery Mode, two controller cards are installed
and a single STS-1 line is coming in (see Figure 7-2). In this mode,
the MX2800 STS-1 can continue operating in the event of a
controller card failure. When both cards are healthy, the primary
card actively processes data while the secondary card stands by
ready to take over if the first fails. The secondary card continuously
monitors the line and remains framed to the incoming signal.
See Table 7-1 on page 7-4 for a list of this mode’s configuration
requirements.
During a card switch, service interruption is experienced on both
the STS-1 and the DSX-1 connections. However, since the
secondary controller card remains framed to the incoming signal
at all times, it is a minimal interruption.

CIRCUIT AND NETWORK FAILURE RECOVERY MODE
In this mode, two controller cards are installed and connected to
two individual STS-1 lines. This is, of course, the most complete
mode of redundancy. In this mode, the primary controller card is
connected to the primary STS-1 line and the secondary controller
card is connected to the secondary STS-1 line. The primary card
and line actively transmit data, while the other card and line stand
by ready to take over if the first card and line fail. For example, if
CARD A fails, then control switches to CARD B and NET B.
An important feature of the MX2800 STS-1 is its ability to
internally re-route the network connection if a controller card and
the opposite network connection fail. For example, in the
illustration given in Figure 7-3, failed NET A is connected to
healthy CARD A; and healthy NET B is connected to failed CARD B.

In this mode, the MX2800 STS-1 can continue to operate during a
power supply failure, without interrupting service. The power
supplies are load sharing, so either power supply can provide power
for the entire unit.
When the unit is configured with dual internal AC power supplies,
this is the only power protection mode available.

POWER SUPPLY AND SOURCE RECOVERY MODE
In this mode, two power supply cards are installed and are
connected to two individual power sources. The MX2800 STS-1
handles any combination of power source or power supply failure.
Much like the backup design for the controller cards, the MX2800
STS-1 is able to internally re-route the power source if a power
supply card and the opposite power source fail. For example, in the
illustration given in Figure 8-3, failed POWER SOURCE A is
connected to functional CARD A and functional POWER SOURCE B is
connected to failed CARD B. In this case, the MX2800 STS-1
automatically connects POWER SOURCE B to CARD A.
This configuration is only available with DC power supplies.

BATTERY BACKUP MODE
With the installation of the ADTRAN Power Supply/Battery
Charger (PS/BC) and backup battery pack, the MX2800 STS-1 is
able to continue operation without service interruption during a
power outage. This PS/BC (P/N 4175043L2) provides -48 VDC to
the MX2800 STS-1. It receives 115 VAC through a standard plug
and wall socket.
The PS/BC maintains the battery at peak charge (-48 V) at all times.
If AC power is lost, the unit automatically transfers power to the
battery without interrupting service. When AC power returns, the
unit switches back to AC power and recharges the battery. For
installation instructions, refer to the guide provided with the
PS/BC. See Figure 8-4 for an illustration of this setup.

Transaction Language 1 (TL1)
INTRODUCTION
Transaction Language 1 (TL1) is a BELLCORE standard used in
the input and output messages that pass between Operations
Systems (OS) and Network Elements (NE) in telecommunication
networks. It was developed to standardize equipment surveillance
and memory administration, and to test with a common format.
This release of TL1 primarily supports the interactive and
autonomous retrieval of system events as part of a valid TL1
session.
OVERVIEW
TL1 is an ASCII-based language that supports both commandresponse and autonomous (NE) message generation. Commonly,
TL1 is used over a X.25 packet network but is completely
independent of any physical layer protocols. For the
MX2800 STS-1, TL1 is implemented as a Telnet session running
over either Ethernet or PPP.
Currently, up to eight simultaneous TL1 Telnet connections can be
active. To manually bring up a TL1 Telnet connection, a Telnet
client is used to request a connection on (TCP) port 3116. A
successful connection will require that the MX2800 STS-1 be
properly configured to operate via the LAN or modem. For
example, in the LAN case, the MX2800 STS-1 must have the LAN
61200659L1-1
MX2800 STS-1 User Manual
9-1
Chapter 9. Transaction Language 1 (TL1)
management port enabled, a valid IP and gateway address, and a
valid subnet mask.
Once the Telnet connection is established, it is necessary to initiate
a TL1 session. Establishing a TL1 session involves successful user
authentication. Until a TL1 session is established, all commands
other than those used to initiate or terminate a session will be
denied (autonomous messaging is also disabled). Authentication
involves the successful entry of a username/password pair. A
table of usernames and associated passwords and privileges is kept
for TL1 authentication. This table is maintained by an administrator
through the VT-100 menus or through a TL1 session. For
information on using the Act-User command to initiate a TL1
session, see the section TL1 Commands on page 9-5.
TL1 MESSAGES
As stated earlier, TL1 messages are either part of a commandresponse exchange or are generated autonomously.
The general format for a TL1 command is as follows:
<VERB>[-<MOD1>[-<MOD2>]]:[<TID>]:[<AID>]:[<CTAG>]:[GB](:<PARAMx>(,<PARAMx>)*)*;
Refer to TL1 Commands on page 9-5 for a list of TL1 commands
supported by the MX2800 STS-1.
TL1 Responses
There are three types of TL1 responses:
• Acknowledgment messages
• Output Response messages
• Autonomous messages
Acknowledgment Messages
Acknowledgment messages are brief output messages generated in
response to received TL1 commands. The MX2800 STS-1
9-2
MX2800 STS-1 User Manual
61200659L1-1
Chapter 9. Transaction Language 1 (TL1)
currently supports two types of acknowledgment messages: In
Progress (IP) and All Right (OK).
In Progress
The IP acknowledgment message is usually generated as an interim
response message to indicate that a message has been received and
that the command is being executed. IP messages have the
following general format:
IP <CTAG><CR><LF>
<
All Right
The OK acknowledgment message indicates that a command has
been received and that the required action was initiated and
completed. This message has the following general format:
OK <CTAG><CR><LF>
<
Output Response Messages
Output Response messages are generated in response to received
commands and have the following general format:
<CR><LF><LF>
<SID> <YR>-<MO>-<DAY> <HR>:<MIN>:<SEC><CR><LF>
M
<CTAG> <COMPLETION CODE><CR><LF>
(<UNQUOTED LINE>|<QUOTED LINE>|<COMMENT><CR><LF>)*
(;|>)
For the MX2800 STS-1, the COMPLETION CODE field will contain
one of the following values:
• COMPLD - Successful execution of the received command
• DENY - Denial of the received command
When the received command is denied, the line in the message
following the COMPLETION CODE line will contain a 4-letter error
code. See the section TL1 Error Codes on page 9-13 for a
description of possible MX2800 STS-1 error codes.

The MX2800 STS-1 specifically uses “quoted line(s)” in the
response message of successfully executed RTRV-ALM commands.
The quoted line format is as follows:
<AID>:<NTFCNCDE>,<CONDTYPE>,<SRVEFF>,<OCRDAT>,<OCRTM>,<LOCN>…
The NTFCNCDE field will contain one of the following values:
• MN - Minor
• MJ - Major
• CR - Critical
Refer to the condition types listed in Table 9-2 on page 9-10
(MX2800 STS-1 Alarm Events) for possible MX2800 STS-1

Autonomous Messages
The Autonomous message is sent from the NE to the OS and is not
associated with any explicit input message. The MX2800 STS-1
uses this message to exclusively report alarmed and non-alarmed
events. An autonomous message has the following general format:
<CR><LF><LF>

TL1 AUTONOMOUS MESSAGES
Autonomous messages provide a mechanism for real time reporting
of system events. Transmission of these messages is disabled by
default and must be explicitly enabled. Although most events
reported are alarms, some events are only informational. The VERB,
MOD1, and MOD2 parameters of the message indicate what type of
event has occurred.
REPT-ALM indicates an alarm event. Table 9-2 lists possible
autonomous messages for alarm events.

10BaseT
Ethernet connector which implements the IEEE standard on 24-gauge,
unshielded twisted-pair wiring.
AMI
Alternate mark inversion. A bipolar line-coding format in T1 transmission systems whereby successive ones are alternately inverted.
ANSI
American National Standards Institute. A non-profit organization that coordinates voluntary standards activities in the United States.
asynchronous
A method of data transmission which allows characters to be sent at irregular
intervals by preceding each character with a start bit, followed by a stop bit.
bandwidth
The bandwidth determines the rate at which information can be sent through a
channel (the greater the bandwidth, the more information that can be sent in a
given amount of time).
baud rate
A measure of transmission speed over an analog phone line. Baud rate measures
the shortest signaling elements per second in the analog signal that a modem
sends over an analog phone line. Does not necessarily equal the bit rate.

BERT
Bit error rate test. A test that uses any of a number of stress patterns to test T3,
T1, FT1, and DDS circuits.
bipolar
A signal containing both positive and negative amplitude components.
bipolar violation
See BPV.
bit
A binary digit representing a signal, wave, or state as either a one or a zero. A bit
is the smallest unit of information a computer can process.
bit error
The receipt of an encoded bit that differs from what was sent by the transmitter.
bit rate
The speed at which bits are transmitted, usually expressed in bits per second
(bps).
bps
Bits per second. The number of bits passing a specific point per second. Examples of common rates are kbps (one thousand bits per second) and Mbps (one
million bits per second). T3 operates at 44.736 Mbps.
BPV
Bipolar violation. A violation in the alternate mark inversion (AMI) line code for
which consecutive 1s are represented by pulses of opposite polarity. BPVs that
are not intentional (B8ZS) are counted as errors. Could also be the presence of
two consecutive 1 bits of the same polarity on the T-carrier line.
bridge
A data communications device that connects two or more networks and forwards
packets between them.
