12.2SX
This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.
Usage Guidelines
The purpose of this command is to convert the collection of the 28 T1 controllers comprising the T3 controller into individual T1 controllers that the system can use. In other words, the Cisco AS5800 access server cannot pass data until a T1 controller is configured (using the controller command), and you cannot configure a T1 controller until it has been created using the t1 command.
Examples
The following example shows how to configure a logical T1 controller at T1 time slot 1 for the T3 controller located in shelf 1, slot 4, port 0. Note that you have to enter the command from controller configuration mode.
Router(config)# controllert3 1/4/0
Router(config-controller)# t1 1 controller

12.2SX
This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.
Usage Guidelines
The BERT test patterns from the CT3IP are framed test patterns (that is, the test patterns are inserted into the payload of the framed T1 signal).
To view the BERT results, use the showcontrollert3 or showcontrollert3brief EXEC commands. The BERT results include the following information:
Type of test pattern selected
Status of the test
Interval selected
Time remaining on the BERT test
Total bit errors
Total bits received
When the T1 channel has a BERT test running, the line state is DOWN. Also, when the BERT test is running and the Status field is Not Sync, the information in the total bit errors field is not valid. When the BERT test is done, the Status field is not relevant.
Thet1bertcommand is not written to NVRAM because it is only used for testing the T1 channel for a short predefined interval and for avoiding accidentally saving the command, which could cause the interface not to come up the next time the router reboots.
Note
T1 channels on the CT3IP are numbered 1 to 28 rather than the more traditional zero-based scheme (0 to 27) used with other Cisco products. This numbering scheme ensures consistency with telco
numbering schemes for T1 channels within channelized T3 equipment.
Examples
The following example shows how to run a BERT test pattern of all zeros for 30 minutes on T1 channel 6 on the CT3IP in slot 9:

Usage Guidelines
If you do not specify the t1clocksourcecommand, the default clock source of internal is used by all the T1s on the CT3IP.
You can also set the clock source for the CT3IP by using the clocksource(CT3IP)controller configuration command.
Note
T1 channels on the CT3IP are numbered 1 to 28 rather than the more traditional zero-based scheme
(0 to 27) used with other Cisco products. This numbering scheme ensures consistency with telco

To remove a T1 as an external port, use the no form of this command.
(Optional) Specifies the cable length, in feet, from the T1 channel to the external CSU or MIP. Values are from 0 to 655. Default is 133.
linecodeami | b8zs
(Optional) Specifies the line coding used by the T1. Values are alternate mark inversion (AMI) or bipolar 8 zero suppression (B8ZS). Default is B8ZS.

12.2SX
This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.
Usage Guidelines
The first three T1 channels (1, 2, and 3) of the CT3IP can be broken out to the DSUP-15 connectors on the CPT3IP so that the T1 channel can be further demultiplexed by the MIP on the same router or on another router.
After you configure the external T1 channel, you can continue configuring it as a channelized T1 (also referred to as a fractional T1) from the
MIP. All channelized T1 commands might not be applicable to the T1 interface. After you configure the channelized T1 on the MIP, you can continue configuring it as you would a normal serial interface. All serial interface commands might not be applicable to the T1 interface.
The line coding on the T1 channel and the MIP must be the same. Because the default line coding format on the T1 channel is B8ZS and the default line coding on the MIP is AMI, you must change the line coding on the MIP or on the T1 so that they match.
To determine if the external device connected to the external T1 port is configured and cabled correctly before configuring an external port, use the showcontrollerst3 command and locate the line
Ext1...
in the display output. The line status can be one of the following:
LOS--Loss of signal indicates that the port is not receiving a valid signal. This is the expected state if nothing is connected to the port.
AIS--Alarm indication signal indicates that the port is receiving an all-ones signal.
OK--A valid signal is being received and the signal is not an all-ones signal.
Note
T1 channels on the CT3IP are numbered 1 to 28 rather than the more traditional zero-based scheme (0 to 27) used with other Cisco products. This numbering scheme ensures consistency with telco
numbering schemes for T1 channels within channelized T3 equipment.
Note
Although you can specify a cable length from 0 to 655 feet, the hardware only recognizes the
following ranges: 0 to 133, 134 to 266, 267 to 399, 400 to 533, and 534 to 655. For example,
entering 150 feet uses the 134 to 266 range. If you later change the cable length to 200 feet, there
is no change because 200 is within the 134 to 266 range. However, if you change the cable length to
399, the 267 to 399 range is used. The actual number you enter is stored in the configuration file.
Examples
The following example shows how to configure T1 1 on the CT3IP as an external port using AMI line coding and a cable length of 300 feet:
Router(config
)
# controllers t3 9/0/0
Router(config

Usage Guidelines
If you do not specify the t1linecodecommand, the default B8ZS is used.
AMI Line Coding
If you select ami line coding for the T1 channel, you must also invert the data on the T1 channel by using the invertdata interface command. This is required because the T1 channel is bundled into the T3 signal, so there are no local T1 line drivers and receivers associated with it. Therefore, the t1channellinecodeami command does not modify local line driver settings. Rather, it advises the CT3IP what line code the remote T1 is using. The CT3IP uses this information solely for the purpose of determining whether or not to enable the pulse density enforcer for that T1 channel.
B8ZS Line Coding
When you select b8zs line coding, the pulse density enforcer is disabled. When you select ami line coding, the pulse density enforcer is enabled. To avoid having the pulse density enforcer corrupt data, the T1 channel should be configured for inverted data.
Note
T1 channels on the CT3IP are numbered 1 to 28 rather than the more traditional zero-based scheme
(0 to 27) used with other Cisco products. This numbering scheme ensures consistency with telco
numbering schemes for T1 channels within channelized T3 equipment.

Usage Guidelines
Note the following when configuring link noise monitoring on T1 and E1 links:
The major-warn and remove keywords cannot be used at the same time; disable one to use the other.
If the warn and remove keywords are specified without any other options, the LCV and PCV thresholds and duration defaults are used to determine set (set) and clear (clear) conditions.
If the span command is issued with the set keyword and the command is not issued again with the clear keyword, or vice versa, the values configured for the threshold and duration is used for both keywords.
If the span command is issued without the set or clear keywords specified, set is the default keyword.
The set and clear keywords can be specified only if the threshold values for the LCV and/or duration is specified.
The threshold for a clear condition must be less than the threshold for a set condition.
The threshold for a warn event must be less than the threshold for a remove event.
The duration is calculated in seconds and is the number of consecutive seconds by which either of the thresholds (exceed or improve) must be surpassed for a condition to occur.
For events, the BER on a line should be greater than or equal to (>=) the thresholds for exceed condition. For improve condition, BER has to be less than (<) the threshold.
If the PCV threshold is not configured (using the pcv keyword and value), this threshold is calculated by the linear extrapolation of the Gaussian probability that is representative of most noise environments based on the configured LCV threshold. If the LCV threshold is specified, it is not mandatory to specify the PCV threshold.
Examples
The following example shows how to generate an exceed event for a minor warning, if the number of LCVs on the T1 line remain above or equal to 20, or the number of PCVs remains above or equal to 10 for 10 continuous seconds.
The following example shows how to generate an improve event for a minor warning, if the number of LCVs on the T1 line remain below 15 or the number of PCVs remain below 8 for 20 continuous seconds.
The following example shows the same threshold value being used by the set and clear conditions, when both keywords are not specified. In this example, the threshold value is 80 for both conditions.
The following example shows how the threshold value specified for the clear condition is used by the set condition when set condition is not specified. In this example, the threshold value of 100 specified for the clear condition is used for the set condition.
The following is a sample output showing the details of the calculated PCV threshold value. The calculated PCV value is 141:

Usage Guidelines
The Cisco 10000 series router is a scalable platform and supports up to 4000 T1 links on one chassis. When enabled, syslog messages are generated for all T1 links on which link noise monitoring is configured. A syslog event is reported as a message. The syslog report stores the last five events.
When an ‘exceed’ event is reported, a syslog message is generated. Such syslog messages from all links clog up the logging buffer. When enabling syslog messages, a message prompts you to confirm whether to generate syslog messages or not.
To view the events for a line card, use the showcontrollertypenumberlnmeventcommand in the privileged EXEC mode. To view the events for a SPA, use the showplatformspaslot/subslotlnmeventcommand.
Examples
The following example shows the message displayed when the minor warning threshold has exceeded:

12.2SX
This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.
Usage Guidelines
You can use the T1 test port available on the CT3IP to break out any of the 28 T1 channels for testing (for example, 24-hour bit error-rate tester (BERT) testing as is commonly done by telephone companies before a line is brought into service).
The T1 test port is also available as an external port. For more information on configuring an external port, see the t1externalcontroller configuration command.
To determine if the external device connected to the T1 test port is configured and cabled correctly before configuring a test port, use the showcontrollerst3 command and locate the line
Ext1...
in the display output. The line status can be one of the following:
LOS--Loss of signal indicates that the port is not receiving a valid signal. This is the expected state if nothing is connected to the port.
AIS--Alarm indication signal indicates that the port is receiving an all-ones signal.
OK--A valid signal is being received and the signal is not an all-ones signal.
Note
T1 channels on the CT3IP are numbered 1 to 28 rather than the more traditional zero-based scheme
(0 to 27) used with other Cisco products. This numbering scheme ensures consistency with telco
numbering schemes for T1 channels within channelized T3 equipment.
Note
Although you can specify a cable length from 0 to 655 feet, the hardware only recognizes the
following ranges: 0 to 133, 134 to 266, 267 to 399, 400 to 533, and 534 to 655. For example,
entering 150 feet uses the 134 to 266 range. If you later change the cable length to 200 feet, there is
no change because 200 is within the 134 to 266 range. However, if you change the cable length to
399, the 267 to 399 range is used. The actual number you enter is stored in the configuration file.
Examples
The following example shows how to configure T1 6 on the CT3IP as a test port using the default cable length and line coding:
Router(config
)
# controller t3 9/0/0
Router(config
-controller)
# t1 test 6

testaimeeprom command is entered, and the recommended user responses.
Table 1 Questions and Responses for test aim eeprom Command
Questions
Responses
AIM Slot [0]:
User responds by entering the slot number of the AIM whose EEPROM is to be modified. If the user presses ENTER, the default slot 0 is used.
Use NMC93C46 ID EEPROM [y]:
User responds with “y” if the AIM contains an NMC93C46 type EEPROM and “n” if the AIM contains an X2444 EEPROM. The compression Advanced Interface Module (CAIM) contains a NMC93C46 EEPROM, and this is the default if the user just pressed ENTER.
AIM Slot %d eeprom (? for help)[%c]
General command prompt for the
testaimeeprom command dialog. The AIM slot number chosen is displayed, and the default command is the last command entered.
Address within slot %d eeprom, [0x%02x]
Enter the desired address within the EEPROM to modify. The default is the next address beyond the byte last modified. If the user wishes to enter a hexadecimal number, it must be preceded by “0x”.
Read or Write access to slot %d at 0x%02x [%c]?
Respond with a W to write to the addressed byte or with an R to read from the addressed byte. The default value is selected by just pressing Enter and is the same as the value specified in the last primitive access.
Write data (hex 8 bits) [%02x]?:
If you respond to prompt B with “W”, then prompt C is issued, requesting the user to enter the data to write to the addressed byte. The user enters the desired value. Note that if the user desires to enter a hex value, the hex value entered must be preceded by “0x”. Otherwise, the value entered is assumed to be in decimal radix.
There is a danger that you can erase all bytes in the entire EEPROM. Though it is good to have a diagnostic tool that allows you to read and write data, there is a danger that lost data will make the Advanced Interface Module (AIM) card fail.
During your session with the test dialog, you have access to the following commands:
Horh
Displays a summary of the available commands.
d
Dump EEPROM contents--Displays the contents of the EEPROM in hex.
e
Erase EEPROM--Erases the entire EEPROM (all bytes set to 0xff).
p
Primitive access--Erases the EEPROM.
q
Exit EEPROM test--Causes the
testaimeepromp command dialog to exit to the command line interface (CLI).
z
Zero EEPROM--Zeros the entire EEPROM.
Examples
The following example displays the
testaimeeprom command user dialog:
Router# test aim eeprom
AIM Slot [0]: 0
Use NMC93C46 ID EEPROM [y]: y
AIM Slot 0 eeprom (? for help)[?]: ?
d - dump eeprom contents
e - erase all locations (to 1)
p - primitive access
q - exit eeprom test
z - zero eeprom

12.2(33)SRA
This command was integrated into Cisco IOS Release 12.2(33)SRA.
Usage Guidelines
Cable diagnostics can help you detect whether your cable has connectivity problems.
The TDR test guidelines are as follows:
TDR can test cables up to a maximum length of 115 meters.
The TDR test is supported on Cisco 7600 series routers running Release 12.2(17a)SX and later releases on specific mdoules. See the Release Notes for Cisco IOS Release 12.2SX on the Catalyst 6500 and Cisco 7600 Supervisor Engine 720, Supervisor Engine 32, and Supervisor Engine 2 for the list of the modules that support TDR.
The valid values for
interfacetypeare
fastethernet and
gigabitethernet.
Do not start the test at the same time on both ends of the cable. Starting the test at both ends of the cable at the same time can lead to false test results.
Do not change the port configuration during any cable diagnostics test. This action may result in incorrect test results.
The interface must be up before running the TDR test. If the port is down, the
testcable-diagnosticstdr command is rejected and the following message is displayed:
Router# test cable-diagnostics tdr interface gigabitethernet2/12
% Interface Gi2/12 is administratively down
% Use 'no shutdown' to enable interface before TDR test start.
If the port speed is 1000 and the link is up, do not disable the auto-MDIX feature.
For fixed 10/100 ports, before running the TDR test, disable auto-MDIX on both sides of the cable. Failure to do so can lead to misleading results.
For all other conditions, you must disable the auto-MDIX feature on both ends of the cable (use the
nomdixautocommand). Failure to disable auto-MDIX will interfere with the TDR test and generate false results.
If a link partner has auto-MDIX enabled, this action will interfere with the TDR-cable diagnostics test and test results will be misleading. The workaround is to disable auto-MDIX on the link partner.
If you change the port speed from 1000 to 10/100, enter the
nomdixautocommand before running the TDR test. Note that entering the
speed1000 command enables auto-MDIX regardless of whether the
nomdixautocommand has been run.
Examples
This example shows how to run the TDR-cable diagnostics:
Router # test cable-diagnostics tdr interface gigabitethernet2/1
TDR test started on interface Gi2/1
A TDR test can take a few seconds to run on an interface
Use 'show cable-diagnostics tdr' to read the TDR results.

Usage Guidelines
If a controller does not go up, or there are a large number of errors associated with a specific E1 controller, you might be able to determine whether the problem is in the server card or in an external line by using the test port. The test port is located on the front panel of the SDH/STM-1 trunk card.
This command does not have a no form because the command itself switches the test port on or off.
To use this command, one E1 controller is selected and the transmit and receive lines can be put into drop or monitor mode. Both drop and monitor modes can be used at the same time on either the transmit or receive lines, but both transmit and receive lines cannot be used in drop or monitor mode at the same time.

12.2SX
This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.
Usage Guidelines
Framed mode allows you to specify a bandwidth for the interface by designating some of the 32 time slots for data and reserving the others for framing (timing). Unframed mode, also known as clear channel, does not reserve any time slots for framing.
This command applies to Cisco 4000, 7000, 7200, and 7500 series routers.
G.703 E1 interfaces have two modes of operation, framed and unframed.
When in framed mode, the range from start-slot to stop-slot gives the number of 64-kbps slots in use. There are thirty-two 64-kbps slots available.
In framed mode, timeslot 16 is not used for data. To use timeslot 16 for data, use the ts16 interface configuration command.
Examples
The following example shows how to enable framed mode on a serial interface on a
G.703 E1 port adapter or an E1-G.703/G.704 port adapter:
Controls the use of timeslot 16 for data on a G.703 E1 interface or on an E1-G703/G.704 serial port adapter.

12.2SX
This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.
Usage Guidelines
If the transmit-buffersbacking-store command is enabled and a full hardware transmit queue is encountered, packets are swapped out of the original memory device (MEMD) into a system buffer in DRAM. If the transmit-buffersbacking-store command is not enabled and the output hold queue is full, packets are dropped instead of being copied if a full hardware transmit queue is encountered. In both cases, the original MEMD buffer is freed so that it can be reused for other input packets.
To preserve packet order, the router checks the output hold queue and outputs previously queued packets first.
Examples
The following example shows how to enable the transmit-buffersbacking-store command on a FDDI interface:
To enable the internally generated clock on a serial interface on a Cisco 7200 series or Cisco 7500 series router when a DTE does not return a transmit clock, use thetransmit-clock-internal command in interface configuration mode.

Usage Guidelines
This command is especially useful for serial interfaces that can send back-to-back data packets over serial interfaces faster than some hosts can receive them.
The transmitter delay feature is implemented for the following Token Ring cards: CSC-R16, CSC-R16M, CSC-1R, CSC-2R, and CSC-CTR. For the first four cards, the command syntax is the same as the existing command and specifies the number of microseconds to delay between sending frames that are generated by the router. Transmitter delay for the CSC-CTR uses the same syntax, but specifies a relative time interval to delay between transmission of all frames.
Examples
The following example shows how to specify a delay of 300 microseconds on serial interface 0:

Usage Guidelines
TUG-3 Command Mode
Use the tug-2 e1 loopback command in configuration controller tug3 command mode to specify a loopback for an E1 line that has been mapped to a TUG-3 via the aug mapping au-4 command.
AU-3Command Mode
Use the tug-2 e1 loopback command in configuration controller au3 command mode to specify a loopback for an E1 line that has been mapped to an AU-3 via the aug mapping au-3 command.
tug-2 e1 loopback network line|path Command
If you configure a loopback to an e1 interface, it will be be looped as configured. However, if a channel group is configured while the loopback interface is still in configuration, the interface driver will ignore the loopback command in the configuration and the serial interface will be activated.
