Cabling and Specifications
The following sections provide specifications for the channelized and electrical interface line card:
•
Power Budget and Signal Specifications
The SONET specification for fiber-optic transmission defines two types of fiber: single-mode and multimode. Signals can travel farther through single-mode fiber than through multimode fiber.
The maximum distance for installations is determined by the amount of light loss in the fiber path. If your environment requires the signal to travel close to the typical maximum distance, you should use an optical time domain reflectometer (OTDR) to measure the power loss.
The following sections describe the power budget and signal specifications for the optics used in the channelized line cards:

Note
T3 Cables
Cisco recommends using RG-179 T3 cables to connect line cards with T3 connectors. The cables are 10 feet long (3.048 meters) and have a female SMB connector on one end, and a female or male bayonet coupling (BNC) connector on the other end. Use the female BNC cable connectors to connect the local line card RX and TX ports. Use the male BNC cable connectors to connect the line card RX and TX ports to other devices. See Figure 18.
Note
Note
If you use cables other than those provided by Cisco, it is your responsibility to ensure that you have a compliant system that meets local EMC requirements. To order additional cables, use the product numbers: 2CBLE-SMB-BNC-M (male) and 2CBLE-SMB-BNC-F (female).
Figure 18 T3 SMB Cables (SMB terminates into BNC)
Note
Figure 19 Connecting T3 Copper SMB Cables
After you connect the cables to a configured port on the line card, it takes up to 35 seconds to initialize and light the green carrier-detected LED.
Note
Building Your Own Cables
You can build your own cables for the T3 connectors on your line card by using the cable components listed in Table 11. All three cables have an SMB connector at one end to connect to the line card. The two SMB-to-BNC cables in Table 11 differ only in that one terminates in a male BNC connector, while the other terminates in a female BNC connector. You can use the third cable for directly connecting two closely spaced line cards back-to-back. These cables have SMB connectors on both ends.
Note
You can order the SMB-to-BNC cables in pairs from Cisco as 2CBLE-SMB-BNC-F female or 2CBLE-SMB-BNC-M male BNC terminations, respectively. Cisco does not sell the SMB-to-SMB cable.
Caution
Cable Attenuation
T3 systems are designed for cable lengths of 450 feet (137 meters) between the transmitter and the DSX-3 demarcation point where the standard pulse mask must be met. From the DSX-3 point, another run of 450 feet (137 meters) is allowed to the receiver, making a total of 900 feet (274 meters) between transmitter and receiver. This limitation is due to signal attenuation in the cable.
Although the American National Standards Institute (ANSI) standard T1.404-1994 stipulates the Western Electric or equivalent 728A SMB cable, it has been replaced by the Lucent (formerly AT&T) 734A cable. Cisco tested more than 900 feet (274 meters) of 734A SMB cable from transmitter to receiver including the SMB-to-BNC adapter cables to verify high signal attenuation.
Table 12 lists some approximate attenuation values from the ANSI standard, and shows the RG-179 attenuation. As you can see, RG-179 has a much higher attenuation, so take this information into account if you plan long runs of RG-179 cable.
Verifying and Troubleshooting the Line Card Installation
The following sections describe how to verify and troubleshoot the line card installation:
•
Initial Boot Process
Note

Alphanumeric LEDs
channelized and electrical interface line cards have two four-digit alphanumeric LED displays at one end of the faceplate, near the ejector lever, that display a sequence of messages indicating the state of the card. In general, the LEDs do not turn on until the RP recognizes and powers up the card. As it boots, the line card displays a sequence of messages similar to those in Table 22.

Troubleshooting the Installation
Note
If the Active LED (Link LED or status LED for line cards with no Active LED) or the alphanumeric display LEDs on a line card do not go on, there is either a problem with the line card installation or a hardware failure. To verify that the line card is installed correctly, follow these steps:
Step 1
Step 2
a.
b.
c.
After the line card reinitializes, the Active LED on the line card should go on. If the Active LED goes on, the installation is complete; if the Active LED does not go on, proceed to the next step.

SONET/SDH Clocking Issues
This section provides an overview of SONET/SDH clocking issues and is applicable to the 1-port channelized OC-48/STM-16 ISE and 4-port channelized OC-12/STM-4 ISE line cards. These line cards support both line and internal clocking functions. Line clocking is derived from the incoming signal from a given port. Internal clocking is derived from the clock that is internal to the line card.
Each port can be configured independently of the other in a line-timed setup, going back as far as the first payload processor. However, on the 1-port channelized OC-48/STM-16 ISE and 4-port channelized OC-12/STM-4 ISE line cards, the second level of payload processing ties the ports to a common clock source that is timed from only one port. This can result in pointer justifications if the remaining ports are not synchronous. However, with a properly configured router, these pointer justifications can be limited to provide the same performance as a SONET cross-connect device.
Note
These line cards use Stratum3 (S3) as the internal clock reference. However, if one of the ports is Stratum1 (S1) accurate, it can be used as the local reference for the system clock. In this case, pointer justifications are very limited. If the system clock is timed from an S1 clock source, from a valid SONET network, then there will be no pointer justifications on any synchronous interface. There are minimal pointer justifications (limited to S1 pointer justifications) on any asynchronous interface if it is on another SONET network. Pointer justification in this case is proportional to the accuracy of the other port clock.
Note
The 1-port channelized OC-48/STM-16 ISE and 4-port channelized OC-12/STM-4 ISE line cards can select an input port as the source of synchronization for the system clock. This eliminates pointer justifications on any port that is synchronous with the selected port. Any other port on that line card that is not synchronous to the selected reference port will encounter pointer justifications at a rate proportional to clock accuracy of the port.
If the port is locally timed, it is Stratum3. If the port is line-timed, it depends on the attached network. It could be another Stratum3 clock, a Stratum1, or something much worse. This issue only applies to multi-port cards and can be avoided if all ports on the line card are connected to the same SONET/SDH network.

Configuring the 1-Port Channelized OC-12/STM-4 (DS1/E1) ISE Line Card
The following procedure describes how to perform a basic controller configuration. After you verify that the new line card is installed correctly, enter the privileged EXEC mode with the enable command. The system prompts you for a password if one is required. Use the configure command to configure the controller.
A Cisco 12000 Series Router identifies an interface address by its line card slot number and port number, in the format slot/port. For example, the slot/port address of an interface on an 1-port channelized OC-12/STM-4 (DS1/E1) ISE line card installed in line card slot 2 and port 0 is 2/0. Even if the card contains only one port, you must use the slot/port notation.
Use the following procedure to configure the 1-port channelized OC-12/STM-4 (DS1/E1) ISE line card. Press the Enter key after each configuration step unless otherwise noted.

Available Configurations for the 1-Port Channelized OC-12/STM-4 (DS1/E1) ISE Line Card
The 1-port channelized OC-12/STM-4 (DS1/E1) ISE line card channelizes up to 840 channel groups of DS1, fractional DS1, or NxDS0 and 168 MLFR/MLPPP T1 bundles. It provides 12 STS-1 interfaces, in either VT-15 mode or CT3 mode. In either case, each STS-1 contains 28 T1 channels for a total of 336 T1 channels per line card. In addition, E1 channels are supported under SDH framing, with Administrative Unit Group (AUG) mapping set to AU-4. Configuration of the 63 E1s is done per Tributary Unit Group-3 (TUG-3). Each TUG-3 comprises seven TUG-2s. Each TUG-2 can be configured to carry up to three E1s mapped into TU-12s.
For more information on configuring the 1-port channelized OC-12/STM-4 (DS1/E1) ISE line card, refer to the Cisco IOS Software Configuration for the Cisco 12000 Series 1-Port Channelized OC-12c/STM-4 to DS1/E1 Line Card document.

Configuring the 6-Port Channelized T3 (T1) Line Card Controller
Procedures and examples for configuring the T3 controller on the 6-port channelized T3 (T1) line card are presented in the following sections:
•
•
•
•
•
Selecting a T3 Controller
You must enter the controller T3 slot/port command before any other configuration commands to select the T3 controller you want to configure. The example that follows is for a 6-port channelized T3 (T1) line card in slot 6 of a Cisco 12000 Series Router:
Router# configure terminalEnter configuration commands, one per line. End with CNTL/Z.Router(config)# controller T3 6/0Router(config-controller)#Setting the Framing Type for the T3 Controller
To specify the framing type, use the controller command framing [c-bit | m23 | auto-detect].
You can set c-bit framing format as follows:
Router(config-controller)# framing c-bitRouter(config-controller)#You can set m23 framing format as follows:
Router(config-controller)# framing m23Router(config-controller)#Specifying the Cable Length
For the cablelength value command, user-specified T3 cable lengths are structured into ranges as follows: 0 to 49 feet and 50 to 450 feet. If you enter a cable length value that falls into one of these ranges, the range within which that value applies is used.
Note
To specify cable length, use the cablelength value controller configuration command
where

•
An example follows that specifies a cable length of 40 feet (12 meters).
Router(config-controller)# cablelength 40Router(config-controller)#
Note
Setting the Clock Source for the T3 Controller
To set the selected T3 controller, use the clock source {internal | line} controller configuration command. The default is clock source internal.

Shutting Down the T3 Controller
You can shut down the T3 controller on the 6CT3-SMB line card with the shutdown controller configuration command. This command sends a DS3 idle signal toward the network. You can bring the T3 controller back up with the no shutdown controller configuration command.
The following example is for a 6-port channelized T3 (T1) line card in slot 6/port 0 of a Cisco 12000 Series Router:
Router(config)# controller T3 6/0Router(config-controller)# shutdownRouter(config-controller)#Configuring the T3 Controller to Respond to Remote T3 Loopback Commands
This section explains how to use the equipment [customer|network] loopback controller configuration command.
To enable the 6-port channelized T3 (T1) line card to respond to remote T3 loopback commands from the remote T3 equipment, use the equipment customer loopback command.
Router(config-controller)# equipment customer loopbackRouter(config-controller)#orTo enable the 6-port channelized T3 (T1) line card to ignore remote T3 loopback commands, use the equipment network loopback command.
Router(config-controller)# equipment network loopbackRouter(config-controller)#
Note
Configuring the 6-Port and 12-Port DS3 Line Card Controller
This section provides basic information to configure an interface and to specify IP routing. You can also enter other configuration commands and options, depending on the requirements of your system. To configure the 6-port and 12-port DS3 line card interfaces, you must identify the router slot where the line card is installed (for example, slot 7).

The three most common types of line card failures are:
•
•
•
In the example above, the line card has failed and has caused a reload because of a software forced crash exception. Once you have determined the cause and collected the necessary output, you can check for any caveats in your Cisco IOS software release using the Bug Toolkit (available to registered Cisco.com users only).
Checking the Current Status of the Line Card
Once you have determined if the problems are caused by system errors in the log or an actual crash, it is important to check the current status of the line card to see if it has recovered from the failure. The status of individual line cards can be identified either by examining the alphanumeric LEDs located on the front of the line card, or by issuing the show led command.
show led Output
Router# show ledSLOT 1 : RUN IOSSLOT 6 : DNLD FABLSLOT 7 : RP ACTVSLOT 10 : RUN IOSSLOT 11 : RUN IOSSLOT 13 : RUN IOSSLOT 14 : RUN IOS
Note
If the alphanumeric LEDs on the line card display anything other than IOS RUN, or the RP is neither the active Master/Primary nor the Slave/Secondary, there is a problem and the line card has not fully loaded correctly. Before replacing the line card, try fixing the problem by following these steps:
Step 1
Step 2
or
Step 3
Fabric Ping Failure
Fabric ping failures occur when either a line card or the secondary RP fails to respond to a fabric ping request from the primary RP over the switch fabric. Such failures are a problem symptom that should be investigated. They are indicated by the following error messages:
%GRP-3-FABRIC_UNI: Unicast send timed out (1)%GRP-3-COREDUMP: Core dump incident on slot 1, error: Fabric ping failure%LCINFO-3-CRASH: Line card in slot 1 crashedYou can find more information about this issue on Cisco.com in the Troubleshooting Fabric Ping Timeouts and Failures on the Cisco 12000 Series Internet Router publication.
Error Messages
If you receive any error message related to a line card, you can use the Error Message Decoder Tool (on Cisco.com) to find the meaning of this error message. Some errors point to a hardware issue, while others indicate a Cisco IOS software caveat or a hardware issue on another part of the router. This publication does not cover all these messages.
Note
Line Card Alarm and Event Detection
This section assumes that you are familiar with SONET/SDH alarm and signal events for SONET line cards and DS3/E3 alarms and line states for DS3/E3 line cards. Your line card does not have an LED for alarm and event detection, but you can enter the show controllers EXEC command to verify whether the alarm and event detection messages are active or inactive. Most alarm and event detection messages are short-lived, because if problems occur, the line card clears the error condition, but records the event to verify line card operation status.
To display SONET alarms, use the show controllers sonet command; to display DS3 or E3 alarms, use the show controllers serial command.
The output from the show controllers serial slot/port EXEC command sends messages about the following types of alarms and events:
•
•
•
•
•
The output also indicates whether the alarm or event originates from the local end connector or the remote end connector.
Some of the alarm and signal events for the SONET line cards are enabled for reporting by default. Others can be enabled individually. What the show controllers sonet privileged EXEC command displays depends on the configuration of the SONET port.
The following partial output example from the show controllers sonet privileged EXEC command shows alarm and event information for the second SONET controller in slot 3 of a Cisco 12000 Series Router (4-port channelized OC-12/STM-4 ISE line card):

Note
Line card field diagnostic software is bundled with the main Cisco IOS software to enable you to test whether a suspect line card is faulty. To use this feature, you must be in privileged enable mode, and issue the diag slot [verbose] command.
While the diagnostic test is running, the line card does not function normally and cannot pass any traffic for the duration of the testing. Without the verbose keyword, the command provides a truncated output message. When communicating with the Cisco TAC, the verbose mode is helpful in identifying specific problems. The output of the diagnostic test without the verbose command appears like the following example:

In the example above, the line card failed the test and did not reload automatically. You can manually reload the line card by using the hw-module slot slot reload command.
Field diagnostic results are stored in an EEPROM on the line card. It is possible to view the results of the last diagnostic test performed on the line card by executing the diag slot previous command.
There are some caveats that exist that cause diagnostic tests to fail, even though the line card is not faulty. As a precaution, if the line card fails and had been replaced previously, you should review this output with the Cisco TAC.
Line Card Diagnostics Using Cisco IOS Software Release 12.0(22)S and Later
Note
Line card field diagnostic software is designed to identify any faulty line card within a Cisco 12000 Series Router. Before Cisco IOS Software Release 12.0(22)S, the field diagnostic software was imbedded within the Cisco IOS software. Starting with Cisco IOS Software Release 12.0(22)S, this software is unbundled from the main image and must be downloaded from Cisco.com using the IOS Upgrade Planner.
Cisco initiated this change to accommodate users with 20-MB Flash memory cards. Field diagnostics are now stored and maintained as a separate image under the following name:
c12k-fdiagsbflc-mz-xxx-xx.s (where xxx-xx is the version number)
This image must be available on a separate Flash memory card, Flash disk, or TFTP boot server in order to load line card field diagnostics. The latest version is always available on Cisco.com. RP and fabric tests remain embedded within the main Cisco IOS software image.
While the diagnostic test is running, the line card does not function normally and cannot pass any traffic for the duration of the testing (5 to 20 minutes depending upon the complexity of the line card). Without the verbose keyword, the command provides a truncated output message. When communicating with the Cisco TAC, the verbose mode is helpful in identifying specific problems. The output of the diagnostic test without the verbose command appears like the following example:

If the line card fails the test, it will not reload automatically. You can manually reload the line card by using the hw-module slot slot reload command.
Field diagnostic results are stored in an electrically erasable programmable read-only memory (EEPROM) on the line card. It is possible to view the results of the last diagnostic test performed on the line card by executing the diag slot previous command.
There are some caveats that exist that cause diagnostic tests to fail, even though the line card is not faulty. As a precaution, if the line card fails and had been replaced previously, you should review this output with the Cisco TAC.

Checking the Installation of Line Card Memory
After you install line card memory and reinstall the line card in the router, the router reinitializes the line card and detects the memory change as part of the reinitialization cycle. The time required for the router to initialize can vary with different router configurations and memory configurations. A router with larger SODIMMs, for example, might take longer to boot.
If the line card does not reinitialize properly after you upgrade the SODIMMs on the line card, or if the console terminal displays a checksum or memory error, verify that you installed the correct SODIMM module and that it is installed correctly on the line card.
To check the installation of line card memory, follow these steps:
Step 1
Step 2
If a SODIMM is not correctly aligned, remove it and reinsert it.
Step 3
If the card fails to restart properly after several attempts and you are unable to resolve the problem, access Cisco.com or contact your Cisco service representative for assistance. Before calling, make note of any console error messages, unusual LED states, or other router indications or behaviors that might help to resolve the problem.

Using the online TAC Case Open Tool is the fastest way to open P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer. The online TAC Case Open Tool is located at this URL:

For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.
To open a case by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete listing of Cisco TAC contacts, go to this URL:

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
