Introduction
PRODUCT OVERVIEW
The MX2810 is an M13 multiplexer that consolidates T1 and E1
signals into a T3 circuit. This unit provides a cost-effective, versatile
tool for combining independent T1s, E1s, or a combination of the
two over the same T3 circuit.
The MX2810 houses two hot-swappable controller cards which
provide 1:1 redundancy for the T1 and T3 signals, as well as the T3
connections.
Embedded SNMP (simple network management protocol) and
TELNET are available through the 10BaseT Ethernet port. Using
the Management Information Base II (MIB II), RFC 1407 standards,
and an ADTRAN enterprise MIB, the MX2810 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 MX2810
events in realtime. This information can be useful during
installation setups and/or troubleshooting.
Complete configuration, loopbacks, and performance monitoring
are available through SNMP, TELNET, or a VT100 terminal
interface. This connection can be made via Ethernet, a local EIA-232
link. The MX2810 is designed for installation in a 19-inch or 23-inch
rack.

Chapter 1. Introduction
The major features of the MX2810 are as follows:
•
•
•
•
•
•
•
•
•
•
•
•
Built-in 1:1 redundancy
Hot-swappable controller cards
Independent, dual-load sharing, redundant power supplies
Embedded SNMP and TELNET management through 10BaseT
Ethernet
Detailed performance monitoring for local and remote units
Simplified configuration through the VT100 terminal menu
structure
Capable of backhauling multiple service types (T1/E1)
DC power
External BITS clock option for future STS-1 interface
M13 and C-bit signaling support
NEBS Level 3 compliant
Standard 10-year warranty
Controller Card 1:1 Redundancy
The MX2810 supports two hot-swappable controller cards which
provide 1:1 redundancy for the T1 and T3 signals. With two cards
installed, the MX2810 can recover from circuit failure. See Circuit
Redundancy on page 7-1 for more information.
T3 OVERVIEW
A T3 provides the same bandwidth as 28 T1s. Typically, leasing a T3
line costs the same as eight to ten T1s. Using the MX2810, a single
T3 can provide internet connectivity and voice (local and long
distance) to individual sites across up to 28 individual DSX-1s. T3 is
also extremely cost effective for backhauling local and long
distance voice.
SNMP
The MX2810's embedded SNMP feature allows the unit to be
accessed and controlled by a network manager through the
1-2
MX2810 M13 User Manual
61185001L1-1
Chapter 1. Introduction
10BaseT local area network (LAN) port. The MX2810 supports the
MIB-II standard, RFC 1213, and the ADTRAN Enterprise Specific
MIB.
MIB files are available from ADTRAN in the support section of the
ADTRAN Web page 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.

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
MX2810, TL1 is implemented as a TELNET session running over
Ethernet or an X.25 packet network. Currently, up to eight TL1
TELNET connections can be active at a time.

Chapter 2. Installation and Operation
RACKMOUNT INSTALLATION
The MX2810 can be mounted into a standard 19-inch or 23-inch
equipment rack. Follow these steps to mount your unit into a rack:
1.
Install the mounting flanges on each side of the MX2810 at one
of the three available positions.
Be sure to install the flanges with the screws provided.
2.
After the flanges have been installed, position the MX2810 at
the correct location within the rack and secure the mounting
flanges to the mounting rails of the rack.
3.
Make all network, DSX terminations, 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.
Connect a VT100 terminal device to the CRAFT port on the
front panel of the unit.
4.
Two MX2810s 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
MX2810 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 the overall reliability of the unit.
Connecting the Breakout Panel
The optional breakout panel (P/N 1200291L1) connects to the
MX2810 via the IN and OUT Champ connectors located on the back
of the unit, and provides 28 RJ connectors for the individual T1s/
E1s. Shipment includes two six-foot, 64-pin to 64-pin Amp cables
which allow direct cabling to the MX2810. Connect the breakout
panel’s IN Champ connector to the MX2810’s IN Champ connector
and the breakout panel’s OUT Champ connector to the MX2810’s
OUT Champ connector (see Figure 2-2)

DS3 Configuration
Use the DS3 CONFIGURATION selections to configure the DS3
network settings to match your application. Descriptions of these
settings follow:
Framing
Set the framing format to match the format of the receive signal at
the network interface. The MX2810 supports C-BIT and M13
framing formats.
Line Length
Set the line length to reflect the physical length of the DS3 network
line. Set to LONG if the cabling distance exceeds 225 feet; set to
SHORT if the distance is less than 225 feet.
Timing
In most cases, configure the MX2810 for LOOP timing to derive
timing from the network. However, set to LOCAL if the MX2810 is
the master timing source for the circuit.

Remote Loopbacks
Select FEAC/C-BIT to allow the MX2810 to respond to remote
loopback requests received over either the DS3 Far End Alarm and
Control (FEAC) channel and/or DS2-level C bits. This mode is
valid in both C-BIT or M13 framing formats. Select FEAC to allow
the MX2810 to respond only to remote loopback requests received
over the DS3 FEAC channel. This mode is only valid when using
C-BIT framing. In this mode, DS2 C bit loopbacks will be ignored.
Select C-BIT to allow the MX2810 to respond only to remote
loopback requests received over DS2 C bits. This mode is available
when operating in either C-BIT or M13 framing. In this mode,
FEAC loopbacks received when operating in C-BIT framing will be
ignored. Select DISABLED to ignore all out-of-band loopback
requests (FEAC and DS2 C-BIT). When DISABLED is selected, the
MX2810 will still respond to individual T1 inband CSU/NIU
loopbacks if so configured in the T1/E1 Loopback Detection menu.
XCV Threshold
The XCV (excessive code violations) THRESHOLD sets a limit on CVs
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:
Setting

The unit switches controller cards if...
1E-3
more than one out of every 1,000 bits received on the

Chapter 3. Configuration
Protection Configuration
The MX2810 houses two controller cards for 1:1 protection against
hardware failure. 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.
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, in an
hour, the cards switch more than the MAX SWITCH THRESHOLD, the
unit issues a trap (see page 3-16) and stops switching cards for the
next 24 hours. The default setting is 3 times an hour. This count
may be cleared by clearing PROTECTION SWITCH alarm counts (see
page 5-12).
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.
Miscellaneous
Loopback Timeout
Sets the loopback timeout to DISABLED, 1 MIN., 5 MIN., 10 MIN.,
15 MIN., 30 MIN., 45 MIN. or 1 HR.
DS2 Configuration
The MX2810 can individually frame each of the seven DS2 streams
in M12 (four T1s) or G.747 (three E1s) format. When set to M12
(4XT1), the four T1s for the selected group are framed per ANSI
T1.107. When set to G.747 (3XE1), the first three T1/E1 ports of the
selected group are framed per CCITT G.747 into the DS3 stream.
61185001L1-1
MX2810 M13 User Manual
3-5
Chapter 3. Configuration
The fourth T1/E1 port of the selected group is not available in this
mode. Any combination of M12 (4XT1) and G.747 (3XE1) is
allowed.
T1/E1 INTERFACE
The T1/E1 INTERFACE menu (shown in Figure 3-4 on page 3-6)
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.
A DS2 can be divided into either three E1s or four T1s. Therefore, when
dealing with an E1 configuration, some of the fields in the T1/E1
INTERFACE menus do not apply (and therefore display N/A).
Figure 3-4. T1/E1 Interface Menu
T1/E1 State
Set T1/E1 lines to DISABLED, ENABLED, OR AUTO ENABLE. In Auto
Enable, the unit automatically detects when a T1/E1 is connected
and enables that T1/E1 line. (See Figure 3-5).

T1/E1 Circuit Protection
T1/E1 Circuit Protection determines which circuit will be allowed
to initiate a protection switch if a failure in the circuitry for that
channel is detected (see Figure 3-10 on page 3-10). If a T1/E1 is set
to DISABLED, then the failure of the circuitry of that one channel will
not cause a protection switch. If set to ENABLED, then the failure of a
channel could cause a protection switch to occur (depending on the
PROTECTION THRESHOLD setting in this menu).
The PROTECTION THRESHOLD setting determines how many of the
ENABLED lines must fail before a card switch occurs. If you want the
failure of a single protected (enabled) line to cause a card switch, set
the PROTECTION THRESHOLD to 1. Choices include 1 through 28.
Select SET MULTIPLE to set a contiguous group or all of the T1/E1s
to the same value at the same time. See Set Multiple on page 3-7 for
a description of the SET MULTIPLE selection, entering ENABLED or
DISABLED.

located, select START to begin the transfer.
Once Start has been selected, start the XMODEM transfer from
the terminal menu program that is being used by selecting or
typing the file path for the location of the new binary file. See
appropriate documentation for your terminal emulator to
begin XMODEM transfer.
After selecting the binary file, the XMODEM transfer will
begin. If you wish to cancel a transfer in progress, press Ctrl-x
three times. The ACT LED on the active card is solid amber for
the duration of XMODEM transfer. The ACT LED on the
stand-by card is blinking green.
If updating a unit with redundant controller cards, the active
controller will begin uploading the new code to the stand-by
controller after the XMODEM transfer has completed and the
unit has successfully loaded and programmed the new
software into its FLASH memory. If the unit does not have
redundant controller cards, go to step 7.
While the stand-by card is having code uploaded, the ACT
LED on the stand-by card will be solid amber. After the code
has finished uploading to the stand-by card, the card will reset
itself and begin running the new code.
The stand-by card must remain in place until the upload process
is complete and the ACT LED is no longer solid amber and
returns to blinking green. Removing the stand-by card during
the uploading process will corrupt the software.

CSU Loopback
A CSU LOOPBACK enables the MX2810 to generate a CSU loop up
pattern (001001…) toward 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 toward the network. A loop
down pattern (0000100001….) will be generated toward 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 MX2810 to test the local T1
loop to the CSU using the standard 511 pseudorandom bit
sequence. When CSU LOOPBACK W/BERT is selected, the MX2810
will initiate a CSU loopback toward 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 MX2810 will
cease sending the CSU loop up pattern and begin sending an
unframed 511 pattern toward the CSU. If the CSU device
responded to the CSU loop up pattern, the MX2810 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 511 pattern and start
transmission of a loop down pattern as previously described.
When in CSU LOOPBACK W/BERT, only the DATA MODE for the T1
under test may be selected. Selecting any other option will result in an
error message being displayed.

A LINE BERT enables the MX2810 to perform a “head-to-head”
BERT test toward the T1 line/loop. Selecting LINE BERT will
replace all incoming network traffic for the selected T1 with an
unframed 511 pattern toward the T1 line/loopU. When LINE 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 511 pattern
generation and substitution of the incoming data stream.
When in LINE BERT mode, only the DATA MODE option for the T1
under test may be selected. Selecting any other option will result in an
error message being displayed.
Only one T1 port may engage a CSU LOOPBACK, CSU LOOPBACK W/
BERT, or a LINE BERT. If a CSU LOOPBACK, CSU LOOPBACK W/

Line Loopback
LINE LOOPBACK performs a loop of the DS3 back to the network.
This loopback occurs just prior to the DS3 framer and B3ZS
decoder, but it makes full use of the DS3 LIU in both receive and
transmit directions; therefore, any coding violations received by the
DS3 will be inserted back into the network without modification.
See Figure 6-9 on page 6-8 for an illustration of this test.
If a LINE LOOPBACK is active when the MX2810 is operating in the
LOCAL timing mode, the timing source for the DS3 is effectively removed
from the circuit. Therefore, it is up to the test equipment or network to
provide DS3 timing into the circuit for the duration of the test.

Remote Loopback
A REMOTE LOOPBACK performs a loopback on the far-end M13
multiplexer. The form of this loopback code sent to the far-end will
depend on the framing mode being used. When in C-Bit parity
mode, the MX2810 will send loopback commands over the FEAC
channel. When operating in M13 framing mode, the MX2810 will
send C-Bit loopbacks at the DS2 level.
Remote all T1/E1
A REMOTE ALL T1/E1 loopback performs a loopback of all T1/E1
channels on the far-end M13 multiplexer. If an MX2810 is located at
the far end, an ANALOG LOOPBACK is executed on all active
channels simultaneously. This loopback is only available when the
DS3 is configured for C-bit parity framing since it requires the
availability of the FEAC channel (see ANSI T1.107).

CIRCUIT FAILURE RECOVERY MODE
In Circuit Failure Recovery Mode, two controller cards are installed
(see Figure 7-2). In this mode, the MX2810 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
DS3 and the DSX1 connections. However, since the secondary
controller card remains framed to the incoming signal at all times, it is a
minimal interruption.

any combination of power source or power supply failure.
Much like the backup design for the controller cards, the MX2810 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 healthy
CARD A and healthy POWER SOURCE B is connected to failed CARD
B. In a case like this, the MX2810 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 MX2810 is able to
continue operation without service interruption in the event of a
power outage. This PS/BC (P/N 4175043L10) provides -48 VDC to
the MX2810. 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.
The MX2810 can operate on a fully-charged battery for four hours
without recharging.

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 MX2810, TL1
is implemented as a TELNET session running over Ethernet or over
an X.25 packet network.
The MX2810 supports an RS-232 compatible serial interface to be
used in conjunction with the X.25 network. The unit includes PAD
functions onboard so an external PAD is not required for operation
with the X.25 network (an external PAD may be necessary when the
unit is being used with a test network with a PC.) Physical access
uses a 25-pin female DB-25 connector (Network Management) on
the rear of the MX2810. The X.25 connector pin assignments are
detailed in Table 1. This port operates as a DTE and is configured
for the following settings:

In order to initiate a TL1 session successfully, the unit must be
properly configured for an Ethernet (LAN) or X.25 connection. A
valid IP address, gateway address, and a valid subnet mask are
required. User authentication is also required. An account must be
setup before initiating a TL1 session.

An account may be setup via the VT100 menus (Configuration/
System Management/System Security/User Account
Management.) An account includes a username, password, and
privileges. The privileges include ADMIN, GUEST, INTERFACE,
TEST, and DISABLED (see Table 9-2). ADMIN privileges allow the
user to use all supported commands. TEST privileges allow the
user to use all supported commands with the exception of
modifying the user account information, configuring alarm relays,
and setting the MX2810 date and time. INTERFACE privileges
allow the user to use all supported commands with the exception of
modifying the user account information, setting the MX2810 date
and time, configuring alarm relays, and operating loopbacks.
GUEST privileges only allow the user to activate the TL1 session,
cancel a TL1 session, and retrieve specific system information.

To bring up a TL1 TELNET connection (up to eight may be
active,) a TELNET client is used to request a connection on (TCP)
port 3116. 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.) For information on using the Act-User command to
initiate a TL1 session, see the section TL1 Commands on page 9-11.
TL1 MESSAGES
As stated earlier, TL1 messages are either part of a commandresponse exchange or are generated autonomously.
A TL1 command has the general format of:
<verb>:<tid>:<aid>:<ctag>:<general block>:<keyword block>:<state block>;
where:
<verb> is the type of TL1 command such as ED or RTRV. The
"verb" may have modifiers as well that are separated by a dash.
<tid> is the Target Identifier. The Target Identifier is the same as
the Unit Id that is set in the menus. The Target Identifier may be
left empty.
<aid> is the Access Identifier.
9-4
MX2810 M13 User Manual
61185001L1-1
Chapter 9. Transaction Language 1 (TL1)
<ctag> is the Correlation Tag, a 1 to 6 character alphanumeric
identifier that is echoed in the response message for the command.
<general block> is unused in this application and should be empty.
<parameter block> is a block that is used in many of the setup TL1
commands. There may be more than one parameter block. If there
is, they will be separated by a comma.
<keyword block> is a block that is used in TL1 Edit and RTRV
commands.
<state block> is unused in this application and should be empty.
The field separator character is a colon.
The terminator of a TL1 command is a semicolon (not a carriage
return). The terminator may be used after the last non-empty field
without supplying the remaining colon separators.
An example TL1 command is:
ACT-USER::username:::password;
This command initiates a TL1 session. The <verb> is “ACT,” its
modifier is “USER” separated by a dash. There is no <tid>, but its
field separator remains. The <aid> in this example is the login
username where the value was “username.” The <ctag> is optional
and was not used in this example, but the field separator remains.
There is no <general block>, but the field separator remains. The
<keyword block> in this example is the login password where the
value was “password.” The semicolon terminates the TL1
command. It is not necessary to maintain the field separator colon
for the <state block>, because the <keyword block> was the last
field used.
Refer to TL1 Commands on page 9-11 for a list of TL1 commands
supported by the MX2810.
TL1 Responses
There are three types of TL1 responses:
• Acknowledgment messages
• Output Response messages
• Autonomous messages
61185001L1-1
MX2810 M13 User Manual
9-5
Chapter 9. Transaction Language 1 (TL1)
Acknowledgment Messages
Acknowledgment messages are brief output messages generated in
response to received TL1 commands. The MX2810 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>
^^^<tid>^<date>^<time><cr><lf>
M^^<ctag>^<code><cr><lf>
^^^<errcode><cr><lf>;
Where
<cr> is the Carriage Return,
<lf> is the Line Feed,
the carrot (^) symbol represents a one space character,
<tid> is the shelf's unit ID,
9-6
MX2810 M13 User Manual
61185001L1-1
Chapter 9. Transaction Language 1 (TL1)
<date> is the date in the form YY-MM-DD,
<time> is the time in the form HH-MM-SS,
<ctag> is the correlation tag from the command line,
<code> is the completion code:
COMPLD indicates normal completion
DENY indicates an error condition
<errcode> is one of the error codes. This line only appears after a
DENY condition.
An example of a normal TL1 response is:
Unit 1 01-10-09 16:20:05
M 1 COMPLD
In this example, "Unit 1" is the unit ID or <tid> that was set in the
menus. "01-10-09 16:20:05" is the date and time stamp. The second
line contains the <ctag> and the <code> which was COMPLD. This
indicates a normal completion.
An example of a TL1 response that contains an error code is:
Unit 1 01-10-09 16:20:05
M 2 DENY
ICNV
In this example, "Unit 1" is the unit ID or <tid> that was set in the
menus. "01-10-09 16:20:05" is the date and time stamp. The second
line contains the <ctag> and the <code> which was DENY. The
third line contains an error code since there was an error condition.
The error code may be looked up in the TL1 Error Code table
located in this document.
See the section TL1 Error Codes on page 9-23 for a discussion of
possible MX2810 error codes.

Chapter 9. Transaction Language 1 (TL1)
The MX2810 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 9-4 on page 9-19
(MX2810 Alarm Events) for possible MX2810 CONDTYPE codes.
Autonomous Messages
The Autonomous message is sent from the NE to the OS and is not
associated with any explicit input message. The MX2810 uses this
message to exclusively report alarmed and non-alarmed events. An
autonomous message has the following general format:
<cr><lf><lf>
^^^<tid>^<date>^<time><cr><lf>
<alarm code>^<atag>^<verb>[^<modifier>[^modifier>]]<cr><lf>
^^^"<aid>:<message parameters>"<cr><lf>;
Where
<cr> is the Carriage Return,
<lf> is a Line Feed,
the carrot (^) symbol represents a one space character,
<tid> is the shelf's unit ID,
<date> is the date in the form YY-MM-DD,
<time> is the time in the form HH-MM-SS,
<alarm code> is the alarm code. The alarm code indicates the
severity of the autonomous message.
9-8
MX2810 M13 User Manual
61185001L1-1
Chapter 9. Transaction Language 1 (TL1)
Possible values for the ALARM CODE field include:
• *C - Critical Alarm
• ** - Major Alarm
• * - Minor Alarm
• A - Non-alarm
• NULL - (blank)
The <atag> parameter is the Autonomously Generated Correlation
Tag (ATAG). It is a decimal number assigned by the NE. It must be
sequential and must be included in all autonomous messages. The
ATAG allows an OS to determine if it has failed to receive any
autonomous outputs by checking for omissions in the sequence of
messages received.
The <verb>[^<modifier>[^<modifier>]] entry identifies the nature
of the autonomous output and allows for quick identification of the
semantics of the information in the text block. It consists of up to
three valid TL1 identifiers separated by the space character (^).
The first identifier (<verb>) is the autonomous message verb and is
a required entry. In most cases, the verb in an autonomous message
will be REPT (Report). The autonomous message verb can have up
to two optional modifiers. Thus, valid forms are <verb>,
<verb>^<modifier> and <verb>^<modifer>^<modifier>. The first
identifier following the verb is used to modify the verb. The
second modifier is used to specify the object generating the
message. Certain modifiers mean that the <aid> parameter (if it
exists) is addressing a particular type of entity in the NE.
<message block> is the detailed data related to the specific alarm or
report.
An example of an autonomous message alarm is:
Unit 1 01-10-09 16:20:05
*C 1 REPT ALM T3
"301:CR,LOS,SA,10-09,16-20-05,NEND,,,,"
In this example, "Unit 1" is the unit ID or <tid> that was set in the
menus. "01-10-09 16:20:05" is the date and time stamp. The "*C"
indicates that this is a critical alarm. "1" is the <atag> that is
automatically generated. "REPT ALM T3" is the <verb> and its
modifiers. The "301:CR,LOS,SA,10-09,16-20-05,NEND,,,," is the
message. The message contains the <aid>, then the type of alarm,
whether or not it is service affecting, the date in MM-DD format,
61185001L1-1
MX2810 M13 User Manual
9-9
Chapter 9. Transaction Language 1 (TL1)
the time in HH-MM-SS format, and whether the alarm is NEND of
FEND ("Near End" or "Far End").
An example of an autonomous message event is:
Unit 1 01-10-09 16:21:10
A 22 REPT EVT EQPT
"405:PROTNA,TC,10-09,16-21-10,NEND,,,,"
In this example, "Unit 1" is the unit ID or <tid> that was set in the
menus. "01-10-09 16:21:10" is the date and time stamp. The "A"
indicates this is a non-alarm message. "22" is the <atag> that is
automatically generated. "REPT EVT EQPT" is the <verb> and its
modifiers. The "405:PROTNA,TC,10-09,16-21-10,NEND,,,," is the
message. The message contains the <aid>, then the type of event,
tells that it is a transient condition (TC), the date in MM-DD format,
the time in HH-MM-SS format, and whether the event is NEND of
FEND ("Near End" or "Far End").
The MX2810 specifically uses “quoted line(s)” in REPT-ALM and
REPT-EVT autonomous messages. The REPT-ALM message has
the following quoted line format:
<AID>:<NTFCNCDE>,<CONDTYPE>,<SRVEFF>,<OCRDAT>,<OCRTM>,<LOCN>…
The NTFCNCDE field will contain one of the following values:
• CL - Alarm Cleared
• TC - Transient Condition
• MN - Minor
• MJ - Major
• CR - Critical
The REPT-EVT message has the following quoted line format:
<AID>:<CONDTYPE>,<CONDEFF>,<OCRDAT>,<OCRTM>,<LOCN>…
The CONDEFF field will contain one of the following values:
• CL - Standing Condition Cleared
• SC - Standing Condition Raised
• TC - Transient Condition

TL1 Autonomous Messages
Autonomous messages provide a mechanism for real time
reporting of system events. 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.
The default setting for autonomous message reporting is OFF.
In order to enable autonomous message reporting, the following
steps must be followed:
• Initiate a TL1 session by following the setup procedures and
using the ACT-USER command (if this has not been done.)
• Use the ALW-MSG command to enable autonomous
messaging. This command is described in Table 9-3 The
format for the command is:
ALW-MSG-{EQPT[rr]ALL};
Where
{ } means to use one of the following,
rr is either T1, T2, or T3.
61185001L1-1
MX2810 M13 User Manual
9-17
Chapter 9. Transaction Language 1 (TL1)
An example of this command that would enable "all" autonomous
messages is:
ALW-MSG-ALL;
The response to this command would be:
Unit 1 01-10-15 10:34:21
M 0 COMPLD
;
Where
"Unit 1" is the <tid> defined in the menus,
"01-10-15 10:34:21" is the date and time,
"M 0 COMPLD" is the ctag and completion code.
Similarly, to enable just the T1 autonomous messages the following
command could be used:
ALW-MSG-T1;
In order to disable autonomous message reporting, the following
steps must be followed:
• Initiate a TL1 session by following the setup procedures and
using the ACT-USER command (if this has not been done.)
• Use the INH-MSG command to disable autonomous
messaging. This command is described in Table 2. The format
for the command is:
INH-MSG-{EQPT[rr]ALL};
Where
{ } means to use one of the following,
rr is either T1, T2, or T3.
An example of this command that would disable "all" autonomous
messages is:
INH-MSG-ALL;
The response to this command would be:

TL1 Editing
TL1 editing commands allow the MX2810 to be provisioned
through a TL1 session rather than through the menu system that is
accessed using a VT100 terminal emulator. User account
information must be provisioned through the a console menu
session or TL1 session prior to initiating a TL1 session. Once a TL1
session has been initiated using the ACT-USER command
described earlier in this chapter, the TL1 editing commands may be
used. The standard format for an edit command is as follows:
ED-rr::<aid>:<ctag>:::<keyword>=<value>;
•
•
•
61185001L1-1
rr is T1, T2, T3, or EQPT
<aid> is the Access Identifier
<ctag> is a 1 to 6 character correlation tag (echoed in response)
MX2810 M13 User Manual
9-23
Chapter 9. Transaction Language 1 (TL1)
•
•
<keyword> is one of the entries from the following data
dictionaries
<value> is one of the enumerated types in the data dictionaries,
an integer, or Y/N depending on the TYPE..
<ctag> is an optional parameter. The placemarker (:) must remain in
place. The default <ctag> is 0.
TL1 Editing Examples:
ED-T1::106:1:::LBO=133TO266; (this would edit line build out for
T1 #6 to be 133 to 266)
ED-T2::205:2:::DS2CFGMODE=T1; (this would configure T2 #5 for
T1 mode versus E1)
ED-T3::300:3:::DS3MAXNUMSW=3; (this would set maximum
number of switches for controller cards to 3)
ED-EQPT::400:4:::PSTEMPCRITRLY=Y; (this would enable the
alarm relay for power supply temperature critical)
To view the value of a parameter, a retrieve (RTRV) command is
used. The standard format for the RTRV command is as follows:
RTRV-rr::<aid>:<ctag>:::<keyword>;
•
•
•
•
rr is T1, T2, T3, or EQPT
<aid> is the Access Identifier
<ctag> is a 1 to 6 character correlation tag (echoed in response)
<keyword> is one of the entries from the following data
dictionaries
<Keyword> is an optional parameter. When left out, all applicable
Keywords will be retrieved.
<ctag> is an optional parameter. The placemarker (:) must remain in
place. The default <ctag> is 0.
9-24
MX2810 M13 User Manual
61185001L1-1
Chapter 9. Transaction Language 1 (TL1)
TL1 RTRV examples:
RTRV-T1::100:1; (this would return all common parameters for T1s
# 1-28)
RTRV-T1::106:1; (this would return all unique and common
parameters for T1 #6)
RTRV-T1::106:1:::LBO; (this would return the value of line build
out for T1 #6)
RTRV-T2::205:2:::DS2CFGMODE; (this would return the
configuration mode of T2 #5)
RTRV-T3::300:3:::DS3MAXNUMSW; (this would return the setting
for the maximum number of switches for controller cards)
RTRV-EQPT::400:5:::PSTEMPCRITRLY; (this would return the
status of the alarm relay for power supply temperature critical)
The data dictionaries that follow are to be used while performing
TL1 editing or retrieve commands. Each data dictionary contains
four columns. The first column "KEYWORD" gives the values to be
placed in the <keyword> portion of the edit command. The second
column "TYPE" describes the type of <value> that is required to be
entered in the edit command. ENUM requires a text and/or
number string to be entered as the <value>. Y/N requires a "Y" or
"N" representing "yes" or "no" to be entered as the <value>. INT
requires that an integer be entered as the <value>. The third
column "DOMAIN" describes valid entries that may be entered into
the <value> portion of the edit command. The fourth column
"DESCRIPTION" explains each of the edit or retrieve commands.
The following data dictionary (Table 9-7) contains entries that are
used to edit or retrieve options for the DS3 portion of the MX2810.
When performing TL1 edit commands from this table, the value of
rr should be "T3" and the <aid> value should be one of the
following:
300 - All DS3 Circuits
301 - DS3 #1
302 - DS3 Control Card A
303 - DS3 Control Card B

Acceptance Test Procedure
OVERVIEW
This document describes the procedures to be used in performing
acceptance testing of ADTRAN’s Total Access MX2810 M13
Multiplexer. It is assumed that the MX2810 has already been installed,
powered-up, equipped and cabled to the DSX-1 and DSX-3 or connecting
equipment (e.g., DCS) according to the specifications described in the
MX2810 Chassis Practice and local operating company procedures.
This Acceptance Test Procedure (ATP) document assumes testing will be
done via bit error rate tests (BERT) between the DSX-3 or associated
connecting equipment and the DSX-1 or associated connecting equipment
using appropriate DS3/DS1 test equipment. An alternate method of
testing involves the use of an ADTRAN Test Access Module (TAM), also
called a Streaker Card (P/N 1185005L1). The TAM provides the ability to
test DS3 and DS1 cabling integrity following chassis installation and
power-up (no MX2810 Common Control Unit cards are required).
Additional TAM information can be obtained from ADTRAN. That
method of testing is well documented in the TAM I&M Practice and will
not be addressed in this document.
The MX2810 is an M13 multiplexer used to consolidate 28 DS1s onto a
DS3. The unit can be equipped in various ways. The first step will be to
take inventory of the equipment installed. This will determine what tests
can be performed. In general, this document will address the following
areas:

EQUIPMENT VERIFICATION
The installed configuration determines the level of redundancy the unit
supports. There may be one or two Power Supply Units (PSU) and
Controller Card Units (CCU) present. A single Power Supply and
Controller are required for operation without redundancy. Equipping the
shelf with two of each provides full redundancy. The Power Supply Units
are the smaller modules on the left side. The Controller Card Units are the
larger modules toward the center and right of the shelf. Visually note
which cards are installed in the chassis under test.
SYSTEM CONFIGURATION
Before the required tests can be performed, a minimal amount of
configuration must be performed on the MX2810. It is necessary to gain
access to the Provisioning menus through the Craft Port, then set the
desired parameters for the DS1 ports, the DS3 port and the alarm
attributes. The following paragraphs step through the process.
Accessing the Craft Port
The MX2810 has a female DB-9 port labeled "craft" on the left side of the
front panel. This port should be connected to the COM port on a computer
or dumb terminal using a standard DB9 male to DB9 female straightwired RS232 cable. Make these connections and start up a terminal
emulation program if using a computer (e.g., HyperTerminal, Procomm,
Crosstalk, etc.), set to VT100 emulation, and a character format of 9600,
N, 8, 1. Press the <ENTER> key several times. A username prompt
should appear. The default username and password is username. The
default password is password. The input characters for username and
password are not case sensitive. After the logon and password are

61185001L1-1
Appendix A. Acceptance Test Procedure
accepted, the MX2810 Main Menu should appear. This is the screen
from which all other management and control functions are accessed.
Provisioning the DS3 Port
In order for the MX2810 to correctly pass traffic through the system, the
DS3 and DS1 ports need to be properly configured. The provisioning of
the DS3 port will be done in this section, and the provisioning of the DS1
ports will be covered in the following. Note that the <Enter> key is used
to select a function and the <Esc> key is used to back up a level in the
menu system.
1.
From the Main Menu, select Configuration (3), and then select
Network Interface (1). The Network Configuration screen should
appear. Set each of the options on this screen as referenced below. To
change an option, simply enter the corresponding number, hit
<Enter> and follow the prompts.
DS3 Configuration
• Framing = C-Bit (default = M13)
• Line Length = Use 0-225 ft. (default) or 225-450 ft., depending on
the distance to the DS3 Cross connect panel or connecting
equipment.
• Timing = Local (default = Loop)
NOTE: The timing must be set to Local to ensure DS3 frame
synchronization and error free testing during bit error tests,
especially when performing tests to a DS3 loopback. Normal
operation will generally require that this attribute be set back to
Loop (system default) after all acceptance tests are completed.
One exception to the rule would be if connecting two MX2810s
together on a back-to-back basis (DS3s facing one another). In
that situation, one MX2810 would need to be set to Local and the
other to Loop.
• Remote Loopbacks = FEAC/C-Bit (default)
• XCV Threshold = Disabled (default)
Protection Configuration
• Active Controller = A (default)
• Max Switch Threshold = 3 (default)
• Min. Switching Period (sec.) = 10 (default)

Miscellaneous
• Loopback Time Out = 1 hr. (default)
DS2 Configuration (no changes are required to DS2
Configuration)
• DS2 #1 = M12(4xT1)
• DS2 #2 = M12(4xT1)
• DS2 #3 = M12(4xT1)
• DS2 #4 = M12(4xT1)
• DS2 #5 = M12(4xT1)
• DS2 #6 = M12(4xT1)
• DS2 #7 = M12(4xT1)
2.
Press the <Esc> key to get back to the main Configuration Menu.
Provisioning the DS1 Ports
A-4
1.
From the main Configuration menu, select T1/E1 Interface (2).
The Configure T1/E1 Interface menu should be visible. Since there
are 28 DS1 ports to configure and all of them need to be set
identically during acceptance testing, the "Set Multiple" provisioning
feature of the MX2810 will be used during this step. Note, however,
that in most instances no changes will be required since the specified
settings are the system defaults.
2.
To use the Set Multiple feature, simply select the attribute from the
Configure T1/E1 Interface screen. From the Set Multiple screen,
confirm that First = 1 and Last = 28. If not, make the necessary
corrections. Select State (3) to toggle the State as necessary until the
correct setting is displayed and select Apply settings (4) to set all 28
DS1s to that mode. Press <Esc> twice to return to the Configure T1/
E1 Interface menu.
3.
Select T1/E1 State (1). If all channels are set to Auto Enable
(default) press <Esc> to get back to the Configure T1/E1 Interface
menu and proceed to the next step. If not, perform the Set Multiple
routine referenced above.
4.
Select T1/E1 Line Coding (2). If all channels are set to B8ZS
(default) press <Esc> to get back to the Configure T1/E1 Interface
MX2810 M13 User Manual
61185001L1-1
Appendix A. Acceptance Test Procedure
menu and proceed to the next step. If not, perform the Set Multiple
routine accordingly.
5.
Select T1/E1 Line length (3). If all channels are set correctly (0-133,
133-266, 266-399, 399-533 or 533-655 feet) as appropriate for the
installation, proceed to the next step. If not, perform the Set Multiple
routine accordingly.
6.
None of the other settings are important to the acceptance testing
process. As such, they will not be addressed.
7.
Press the <Esc> key to get back to the main Configuration Menu.
Alarm Relay Configuration
Although there are numerous alarm configuration options available on the
MX2810, our interest here is only to have the ability to generate one
CRITICAL, one MAJOR, and one MINOR alarm. This will confirm that
the alarm contacts are wired/operating correctly and transmitting the
appropriate alarm conditions to the Office alarm panel, DANTEL system,
etc. The steps to follow will be required during subsequent alarm testing/
verification.
61185001L1-1
1.
From the main Configuration menu, select System Management
(3). From this menu, select Alarm Relay Configuration (4) to get to
the Alarm Relay Configuration screen.
2.
As necessary, toggle the DS3 LOS (2) state to Enabled. This will
force generation of a CRITICAL alarm when the DS3 port sees a
Loss of Signal condition.
3.
As necessary, toggle the T1/E1 LOS (8) state to Enabled. This will
force generation of a MAJOR alarm when a DS1 port sees a Loss of
Signal condition.
4.
As necessary, toggle the DS3 FEAC (5) state to Enabled. This will
force generation of a MINOR alarm when a DS1 port sees a Loss of
Signal condition and the DS3 is hard looped back as will be the case
during the Alarm Testing process.

Appendix A. Acceptance Test Procedure
OVERALL SYSTEM AND CABLING TEST
Now that the system has been properly provisioned for acceptance testing,
we can proceed with the actual acceptance testing of the system. The first
key test is to verify that the MX2810 will pass traffic between the DS1 and
DS3 ports. Three different methods of testing are presented. One of the
three should be selected based on test equipment availability and network
configuration. All of the tests are performed at the DSX-1 and DSX-3
cross-connect bays or connecting equipment so that both the MX2810
circuitry and the office cabling are tested.
DS1 to DS3 “Head to Head” Test (ordinarily a two-person operation)
This is the preferred means of testing system and cabling integrity. It tests
one DS1 channel at a time using a DS1 test set at the DSX-1 cross-connect
panel or connecting equipment and a DS3 test set at the DSX-3 or
connecting equipment location.
Equipment Required: • 1 DS1 Test Set capable of running a BERT
• 1 DS3 Test Set capable of accessing and running a
BERT on a single DS1
A-6
1.
At the DSX-3 cross-connect panel or connecting equipment, properly
connect the DS3 test set to the DS3 coming from the MX2810
(confirming transmit and receive integrity is integral to the process).
2.
Configure the DS3 test set for C-Bit Framing, the appropriate LBO
and set to drop out DS1 #1. Configure the DS1 BERT to run in ESF/
B8ZS mode using QRSS or other preferred test pattern. Confirm that
the MX2810 sees a good DS3 signal (DS3 STATUS LED is solid
Green on the Active Controller) and that the DS3 Test Set is in
frame synchronization with the MX2810.
3.
At the DSX-1 cross-connect bay or connecting equipment, connect
the DS1 test set to the first DS1 channel of the MX2810. Configure
the test set for the same framing, line code and BERT pattern as the
DS3 test set. Confirm a good, error free BERT for a minimal period,
e.g., 15 seconds).
4.
Repeat for DS1 channels 2-28 by moving the DS1 test cables and
reconfiguring the DS3 test set to drop out the appropriate DS1
channel under test.
MX2810 M13 User Manual
61185001L1-1
Appendix A. Acceptance Test Procedure
5.
The MX2810 will be in an alarm condition because of the previously
tested and now un-terminated DS1 ports, but this should not prohibit a
successful BERT between the DS1 and DS3 test sets on the channel
under test.
6.
Leave this test set-up in place, as it will be used during the
redundancy testing portion of this document. Proceed to Alarm
Verification.
DS1 Daisy-chain to DS3 (Hard) Loopback
(can only be used if DS1s are terminated at the DSX1)
This test can be performed single-handedly. It loads all 28 ports of the
MX2810 with traffic at the same time, but it does not confirm DS3 cabling
integrity (transmit Vs receive).
Equipment Required: • 1 DS1 Test Set for running a BERT
• 28 DS1 Bantam test cords
• 1 DS3 test cord
61185001L1-1
1.
At the DSX-3 cross-connect panel or connecting equipment, loop the
DS3 from the MX2810 back on itself. Confirm that the MX2810
sees a good DS3 signal (DS3 STATUS LED is solid Green on the
Active Controller) and that the DS3 Test Set is in frame
synchronization with the MX2810.
2.
At the DSX-1 cross-connect panel, insert the TRANSMIT of the DS1
test set into the INPUT of the first DS1 channel of the MX2810.
3.
At the DSX-1, install a Bantam test cord from the OUTPUT of the
first DS1 channel to the INPUT of the second, then connect a second
Bantam test cord from the OUTPUT of the second DS1 channel to the
INPUT of the third DS1 channel. Repeat this procedure for all 28
DS1 channels.
4.
Connect the OUTPUT of the 28th DS1 channel to the RECEIVE of
the DS1 test set.
5.
Set the test set options for ESF/B8ZS and run a standard BERT using
QRSS or other preferred test pattern(s).
6.
All alarms should clear on the MX2810 and the BERT should run
error free for a minimal period, e.g., 15 seconds. Troubleshoot as
necessary.

DS1 to DS3 (Hard) Loopback
This test requires minimal test equipment, tests one DS1 at a time and can
be performed single-handedly. It does not verify DS3 cabling integrity
(transmit Vs receive) to the DSX3 or connecting equipment.
Equipment Required: • 1 DS1 Test Set capable of running a BERT test
• 1 DS3 Test Cord
A-8
1.
At the DSX-3 cross-connect panel or connecting equipment, loop the
DS3 from the MX2810 back on itself. Confirm that the MX2810 sees
a good DS3 signal (DS3 STATUS LED is solid Green on the Active
Controller) and that the DS3 Test Set is in frame synchronization with
the MX2810.
2.
At the DSX-1 cross-connect bay or connecting equipment, insert the
TRANSMIT of the DS1 test set to the DS1 INPUT of the first channel
of the MX2810. Connect the RECEIVE of the test set to the
OUTPUT of the first DS1 channel of the MX2810.
3.
Configure the DS1 test set for ESF/B8ZS and the desired BERT
pattern, e.g., QRSS.
4.
All alarms should clear on the MX2810 and the BERT should run
error free for a minimal period, e.g., 15 seconds. Troubleshoot as
necessary.
5.
Repeat the above procedure for DS1 channels 2-28. The MX2810
will be in an alarm condition because of the un-terminated DS1 ports,
but this should not prohibit a successful BERT.
6.
Leave this test set-up in place, as it will be used during the
redundancy testing portion of this document. Proceed to Alarm
Verification.
MX2810 M13 User Manual
61185001L1-1
Appendix A. Acceptance Test Procedure
ALARM VERIFICATION
The MX2810 has three sets of alarm relay contacts available for
connection to external alarm systems. They are located on the back panel
and are designated as CRITICAL, MAJOR and MINOR. Normally
"Open" and "Common" contacts are available for each of the relay
outputs.
In the section above, a test scenario was designed to activate each of the
relays. The CRI (Critical) alarm is activated when the DS3 port
experiences a Loss of Signal (LOS) event. The MAJ (Major) alarm is
activated when one of the 28 DS1 ports experiences a Loss of Signal. The
MIN (Minor) alarm is activated when one of the 28 DS1 ports experiences
a Loss of Signal event and the DS3 is hard looped back on itself, therefore
appearing as a FEAC (Far End Alarm and Control) alarm. FEAC alarms
only occur when the system is provisioned for C-Bit framing, hence the
reason for performing acceptance testing in that mode.
Alarm testing procedures are documented below. Testing of autonomous
alarm reporting, e.g., to NMA, will first require that the system be
configured for remote access. Those procedures are covered in the section
entitled “Configuring the System for Remote Access”.
CRITICAL Alarm Relay Test
This test will actuate the CRITICAL alarm relay contacts.
61185001L1-1
1.
Ensure that the DS3 is not in alarm. The easiest way to do this is to
place a hard loopback of the DS3 toward the MX2810 using a test
cord at the DSX-3 cross-connect panel or connecting equipment.
2.
With the loopback in place, all alarms should clear on the Controller
Module DS3 port (DS3 STATUS LED is solid Green on the Active
Controller).
3.
Remove the loopback from the DS3 and insure that no other DS3
signal is entering the MX2810 through the DSX-3 Cross-connect bay
or connecting equipment, e.g., DCS.
4.
The MX2810 should go into CRITICAL alarm, thus closing the relay
contacts and sending the alarm to the alarm monitoring equipment.
5.
Verify that the alarm is being properly reported (CRITICAL Alarm).
MX2810 M13 User Manual
A-9
Appendix A. Acceptance Test Procedure
MAJOR and MINOR Alarm Relay Test
This test will actuate the MAJOR and MINOR alarm relay contacts.
1.
Ensure that the DS3 is not in alarm (DS3 STATUS LED is solid Green
on the Active Controller). The easiest way to do this is to once again
re-install a hard loopback of the DS3 toward the MX2810.
2.
Ensure that the 28 DS1s are out of alarm. The easiest way to
accomplish this is as follows:
• At the DSX-1 cross-connect, insert the TRANSMIT of the DS1 test
set into the INPUT of the first DS1 channel of the MX2810. Install
a Bantam test cord from the OUTPUT of the first DS1 channel to
the INPUT of the second DS1 channel. Then connect a second
Bantam test cord from the OUTPUT of the second DS1 channel to
the INPUT of the third DS1.
• Repeat this procedure for all 28 DS1 channels. Connect the
OUTPUT of the 28th DS1 channel to the RECEIVE of the DS1 test
set. Configure the test set for ESF/B8ZS and run a standard BERT
test using QRSS or other preferred test pattern(s).
3.
At this point, nothing should be in alarm (DS1 STATUS LEDs are all
solid Green on the Active Controller). Remove any one of the
Bantam cords from the DSX bay. This will cause a DS1 LOS alarm,
which will result in the actuation of the MAJOR alarm relay. Also,
since the DS3 is hard looped back on itself, i.e., the DS3 is not in
alarm, a FEAC alarm will occur to signify an alarm at the DS1 level
reported by the far end (C-Bit framing enables this feature), resulting
in the actuation of the MINOR alarm relay.
4.
Verify that the MAJOR and MINOR alarms are being properly
reported to the Office alarm monitoring equipment.
VERIFICATION OF SYSTEM REDUNDANCY
This section will address the redundancy features of the MX2810. The
MX2810 supports redundancy of both the Power Supply and Controller
Modules. The equipment configuration (non-redundant Vs redundant and
type of power redundancy) will be useful in determining what can and
cannot be tested. The following sections describe the tests for various
configurations.
A-10
MX2810 M13 User Manual
61185001L1-1
Appendix A. Acceptance Test Procedure
Power Supply Redundancy
When installed, the MX2810 can be wired to have either one or two
-48VDC power feeds (A and B). In addition, the MX2810 chassis can be
equipped with either one or two Power Supply Modules. Test scenarios
for the two most common configurations follow. Testing of the other
configurations is nothing more than a subset of what follows.
Single Power Supply Module / Dual Power Feeds
When the MX2810 is equipped with only a single Power Supply Module,
there is no protection against a failure of the module itself. However, the
single Power Supply is capable of utilizing the A and B power feeds to
protect against a failure in one of the power sources feeding the shelf. To
verify that the MX2810 is properly utilizing the A and B power feeds, the
following procedure is suggested:
1.
With the MX2810 installed and operating normally, go to the fuse
panel at the top of the bay and remove the fuse corresponding to the A
power feed for the MX2810 shelf. This should have no effect on the
operation of the shelf or customer service, as the MX2810 is now
operating on the B power feed.
2.
Reinsert the fuse for the A power feed.
3.
Now remove the B power feed fuse for the MX2810 shelf. Once
again, there should be no effect on the operation of the shelf, as the
MX2810 is now operating on the B power feed.
4.
Reinsert the fuse for the B power feed.
Dual Power Supply Modules / Dual Power Feeds
When the MX2810 is equipped with two Power Supply Modules and also
wired to support dual power feeds, the shelf is protected against a failure
of either of the Power Supply cards, as well as a failure of one of the
power sources feeding the shelf. Use the following procedure to confirm
the operation of this fully redundant configuration:
1.
61185001L1-1
With the MX2810 installed and operating normally, remove the A
Power Supply card (the one on the left). This should have no effect
on the operation of the shelf, as the MX2810 is now operating on the
B Power Supply.
MX2810 M13 User Manual
A-11
Appendix A. Acceptance Test Procedure
2.
Go to the fuse panel at the top of the bay and remove the fuse
corresponding to the A power feed. This should have no effect on the
operation of the shelf, as the B Power Supply is now running on the B
power feed.
3.
Reinsert the fuse for the A power feed.
4.
Remove the fuse corresponding to the B power feed to the shelf.
Again, this should have no effect on the operation of the shelf, as the
B Power Supply is now operating on the A power feed.
5.
Reinsert the fuse for the B power feed.
6.
Reinsert the A Power Supply into the MX2810 chassis.
7.
Remove the B Power Supply card (the one on the right). This should
have no effect on the operation of the shelf, as the MX2810 is now
operating on the A Power Supply.
8.
Go to the fuse panel at the top of the bay and remove the fuse
corresponding to the A power feed. This should have no effect on the
operation of the shelf, as the A Power Supply is now running on the B
power feed.
9.
Reinsert the fuse for the A power feed.
10. Remove the fuse corresponding to the B power feed to the shelf.
Again, this should have no effect on the operation of the shelf, as the
A Power Supply is now operating on the A power feed.
11. Reinsert the fuse for the B power feed.
12. Reinsert the B Power Supply into the MX2810 chassis.
13. Confirm both Power Supplies and Power Feeds are functioning as
normal. Faceplate LEDs will identify problems with the Power
Supplies, but the inputs can only be tested via VOM.
Controller Card Redundancy
The MX2810 can be equipped with either one or two Controller Modules.
The Controller contains all of the MX2810's critical circuitry including the
DS3 interface, DS1 interfaces, management and communications
hardware/firmware, etc. If the MX2810 is equipped with only one
Controller, there is no protection against failure. If a failure does occur to
A-12
MX2810 M13 User Manual
61185001L1-1
Appendix A. Acceptance Test Procedure
the Controller, an alarm is initiated and the front panel LEDs reflect the
condition (ACT LED is either solid or blinking Red).
If the MX2810 is equipped with two Controller Modules, all traffic is
protected and can be switched over to the Standby Controller in the event
of a card failure. The following procedures will demonstrate the
functionality of a Controller switchover.
1.
Using the BERT set-up that should still be in place from previous
testing, insure that the system is still passing traffic error-free.
2.
Log into the MX2810 (if necessary) via the Craft Port to get to the
Main Menu screen. From there, select Configuration (3), followed
by Network Interface (1) and Active Controller (6).
3.
This will show which Controller (A or B) is currently Active. If the A
Controller is Active, select Controller B as the Active Controller.
This will force a switch to the B Controller, which is acting as a hotstandby. If the B Controller is the Active Controller, force a switch to
the A Controller.
4.
Traffic will be interrupted momentarily during the switch, but will
quickly return to error free performance again on the new Controller.
5.
Although either Controller can be the Active Controller, for
consistency, the A Controller should be left as the Active one.
NOTE: You must repeat the log-in sequence in Step 2 after each
protection switch.
CONFIGURING THE MX2810 FOR REMOTE ACCESS
The MX2810 supports either Ethernet (10BT) or X.25 communication for
remote management. In the event the MX2810 is to be Remotely
Accessible, the process below can be used to configure the system for
remote access and confirm proper operation.
Assuming remote access will occur via Ethernet 10BT Telnet session,
confirm the 10BT cable is connected to the appropriate HUB/PORT at one
end and to the MX2810 Ethernet port at the other. Perform the following
from the front panel Craft Port following a successful log in:
1.
61185001L1-1
From the Main Menu, select Configuration (3), followed by System
Management (3).
MX2810 M13 User Manual
A-13
Appendix A. Acceptance Test Procedure
2.
From the System Management Configuration screen, select Local IP
Address (1). Enter the correct IP Address, e.g., 10.13.254.27, as
provided by appropriate engineering personnel.
3.
Also from the System Management Configuration screen, enter the
correct Gateway and Subnet Mask addresses.
Once the IP Address info has been entered into the system, the final step in
the process involves assigning a Target ID (TID) to the system. Once
again, this information should be furnished by the appropriate engineering
personnel. An example of a TID is HSTNTXCA01012308S1, where the
first 8 characters are the Office CLLI, followed by an 8-character relay
rack location and a 2-character shelf id. The entire TID is limited to no
more than 20-characters.
The following procedures describe the process of inventorying the TID.
1.
From the Main Menu, select Configuration (3), followed by System
Management (3).
2.
From the System Management Configuration screen, select Circuit
Identification (16).
3.
From the Equipment Identification screen, select Unit ID (1).
4.
Enter the TID exactly as documented.
Assuming the proper Data Communications Network routing translations
have been performed by DCN administration personnel, attempt remote
access via Telnet Session to the shelf from a secure terminal or server
(DCN personnel should be able to do this). Work with DCN personnel as
necessary to troubleshoot problems.
Once the Ethernet connectivity is established to the shelf, NMA personnel
may also be contacted to confirm NMA accessibility for autonomous
alarming and/or remote provisioning/maintenance.
With Ethernet connectivity, remote personnel will also have access to the
user-friendly craft interface screens. Those screens, the same ones
available via the local craft port, will provide access to all OAM&P
(Operations, Administration, Maintenance and Provisioning) functions.
For those situations where X.25 is the transport medium for providing
remote access to the shelf, the Controllers have a built-in PAD and require

61185001L1-1
Appendix A. Acceptance Test Procedure
no settings on the MX2810. The RS232 Data Communication Interface
on the shelf backplane will be used for that type of connectivity.
NOTE: MX2810 chassis’ equipped with X.25 as opposed to Ethernet
connectivity will be limited to TL1 provisioning and maintenance,
i.e., craft-interface accessibility does not exist.
Once the system has been configured for remote access and tested
satisfactorily in that regard, autonomous alarm reporting to NMA can then
be tested. NMA personnel will need to access the shelf, perform the
required login sequence and enable autonomous alarm reporting. Once
that activity has been performed successfully, alarms should be seen by the
NMA system. This process should be verified during acceptance testing
unless local policy dictates otherwise.
RESTORATION OF DEFAULT SETTINGS
After all Acceptance Tests have been successfully completed, the
MX2810 may be restored to its default settings by following the
procedures below.
1.
Log into the MX2810 (if necessary) via the Craft Port. From the
Main Menu, select Configuration (3), followed by Utilities (4) and
Load Default Settings (1).
2.
Once the settings have been retrieved and loaded into the system,
Command Accepted will appear at the bottom of the screen. The
Standby Controller will always maintain an exact copy of the Active
Controller’s attributes. Confirm all settings are as expected via the
Craft Port.
3.
Normalize all loopbacks as appropriate and restore all cabling and
DSX panels to normal.
Office and Autonomous alarms may be generated as a result of performing
step 3 above. DS3 alarms can be cleared by looping the DS3 back toward
the MX2810 and setting the MX2810 Timing to LOCAL via the Craft
Port by selecting Configuration (3), Network Interface (1) and Timing
(3) from the Main Menu, or by ensuring continuity to and proper
provisioning of the MX2810 and connecting equipment.
At the DS1 level, the MX2810 has 3 Service States. They operate as
follows:
61185001L1-1
MX2810 M13 User Manual
A-15
Appendix A. Acceptance Test Procedure
• Disabled – No signal continuity exists through the MX2810 and no
alarms are detected or transmitted.
• Enabled – Signal continuity and alarming are always enabled.
• Auto Enable (default) – Signal continuity and alarming exist only
after a DS1 signal is detected at the DS1 input to the MX2810.
Once a signal is detected, the only way to disable alarming is to
momentarily toggle the DS1 channel to the Disable state as
follows:
From the Main Menu, select Configuration (3), T1/E1 Interface (2) and
T1 State (1). From the T1/E1 State screen, enter the DS1# in question,
and then select Disabled (1) to disable signal continuity and alarm
transmission. Repeat the process of selecting the DS1 from the T1/E1
State screen, but this time select Auto Enable (3) to once again provision
the slot/channel for service. No alarms will be transmitted until a DS1
signal has been detected and removed or an unframed signal is detected.
FINAL SYSTEM CONFIGURATION (TRAFFIC READINESS)
After the previous tests are successfully completed and the default settings
are restored, the MX2810 can be considered ready for customer traffic.
Specific provisioning of the DS3, DS1 and other options is determined by
circuit orders and local practices.
