T1 and E1 Dial Feature Cards

This chapter describes the installation and removal procedures for the T1 and E1 dial feature cards (DFC) and includes the following sections:

•Overview

•Online Installation and Removal of the T1 or E1 DFC

•Configuring Input Impedance for the E1 DFC

•Getting Help

•Where to Go Next

Overview

You can install a T1 or E1 dial feature card in any dial feature card slot of the universal gateway chassis. (See Figure 3-1 through Figure 3-3.)

Each T1 or E1 DFC provides physical line termination for multiple DS-0 channels and uses onboard HDLC controllers to terminate digital (ISDN) calls. For network specifications see Table 3-1 and Table 3-2. You can use the bantam ports on the DFC to monitor a line.

Note The Cisco AS5350 and Cisco AS5400 support only one type of WAN DFC at a time. Refer to "Troubleshooting" for more information.

Online Installation and Removal of the T1 or E1 DFC

Overview

To remove a DFC without dropping any calls or connections, you will need to take the DFC out of service by using the busyout command to disable the DFC. The busyout command is executed on a per DFC basis and will gracefully disable the card by waiting for the active services to terminate.

If you have active calls on the DFC after executing the busyout command, wait for the calls to drop. Use the show busyout command to view the status of the termination process.

Caution The online installation and removal (OIR) of new cards should be done ONLY during times of low CPU utilization, such as during maintenance.
Caution To avoid erroneous failure messages, remove or insert only one DFC at a time.

When you replace a DFC with a new DFC of the same type in the same slot, the system software will recognize the new trunk interfaces and bring them up automatically.

If you replace the existing DFC with a new DFC of a different type, you will have to reconfigure the system. For configuration details, refer to the Cisco AS5350 and Cisco AS5400 Universal Gateway Software Configuration Guide.

Removing the T1 or E1 DFC

To remove the T1 or E1 DFC, follow these steps:

Note Following these steps are examples of the output from each command.

Step 1 Determine which slot the DFC is in by entering the show chassis command in privileged EXEC mode: 

Router# show chassis slot

Figure 3-4 Slot Numbering on the Cisco AS5350 Chassis

Figure 3-5 Slot Numbering on the Cisco AS5400 Chassis

Step 2 Initialize the software busyout procedure by entering the busyout command: 

Router# busyout slot-number

Step 3 Enter the show busyout command to check busyout status for that specific slot: 

Router# show busyout slot-number

Step 4 You may use the clear port command to immediately disable active calls on the universal port card (UPC). For more information on the UPC, see Chapter 5, "Universal Port Dial Feature Card". Use the show controller command to show the universal port card associated with the T1 or E1 DFC. 

Router# show controller t1/e1 slot-number/control-number timeslot timeslot-number

Router# clear port slot-number/port number

Note The clear port command only applies to the universal port DFC.

Step 5 Verify that the OIR/MAINT LED is off; this indicates that the DFC is offline and ready to be removed.

Note The OK/MAINT LED is green before you enter the busyout command. After you enter the busyout command, the LED changes to yellow. The LED turns off after all calls are disconnected and resources are taken out of service, indicating that busyout is complete.

Step 6 Attach an ESD-preventive wrist strap.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

Step 7 Disconnect all interface cables from the DFC and secure them out of the way.

Step 8 Loosen the two captive screws that secure the DFC to the chassis until each screw is free of the chassis. (See Figure 3-6 and Figure 3-7.)

Figure 3-6 Loosen the Captive Screws on the Cisco AS5350

Figure 3-7 Loosen the Captive Screws on the Cisco AS5400

Step 9 Grasp the DFC handle with one hand and pull the card toward you until the card slides free of the chassis. Grasp the ventilated metal cover with your other hand to support and guide the DFC out of the slot. (See Figure 3-8 and Figure 3-9.)

Caution Avoid touching any pins or circuit board components during removal and installation of a DFC.

Figure 3-8 Remove the DFC from the Cisco AS5350

Figure 3-9 Remove the DFC from the Cisco AS5400

Step 10 After you remove the DFC from the chassis, set it aside on an ESD-preventive mat.

Step 11 If the DFC slot is to remain empty, install a blank cover over the open DFC slot to ensure proper airflow inside the chassis. (See Figure 3-10.)

Installing the T1 or E1 DFC

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

Warning The E1 interface card may only be installed in an ACA-permitted customer equipment or a Data Terminal Equipment (DTE) that is exempted from ACA's permit requirements. The customer equipment must only be housed in a cabinet that has screw-down lids to stop user access to overvoltages on the customer equipment. The customer equipment has circuitry that may have telecommunications network voltages on them. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

Warning The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the housing is open. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

Note When you replace a DFC with a new DFC of the same type in the same slot, the system software will recognize the new trunk interfaces and bring them up automatically. If you replace the existing DFC with a new DFC of a different type, you will have to reconfigure the system. For configuration details, refer to the Cisco AS5350 and Cisco AS5400 Universal Gateway Software Configuration Guide.

To install the T1 or E1 DFC, follow these steps:

Step 1 Attach an ESD preventive wrist strap.

Step 2 Slide the DFC into the slot until the connector pins make contact with the carrier card backplane connector. (See Figure 3-11 and Figure 3-12.)

Figure 3-11 Install the T1 or E1 DFC in the Cisco AS5350

Figure 3-12 Install the T1 or E1 DFC in the Cisco AS5400

Step 3 Align the captive screws with their holes, and seat the card completely.

Step 4 Tighten the screws to secure the DFC to the chassis. (See Figure 3-13 and Figure 3-14.)

Figure 3-13 Tighten the Captive Screws on the Cisco AS5350

Figure 3-14 Tighten the Captive Screws on the Cisco AS5400

Step 5 Check the card LEDs to verify that the card is working properly. For information about dial feature card LEDs, refer to "Troubleshooting"

Note For information about configuring the T1 or E1 ports, refer to the Cisco AS5350 and Cisco AS5400 Universal Gateway Software Configuration Guide.

Configuring Input Impedance for the E1 DFC

Use the line-termination command to set the input impedance for the E1 DFC.

You can set the input impedance before or after running the setup script. For information on configuring the universal gateway with the setup script, refer to the Cisco AS5350 and Cisco AS5400 Universal Gateway Software Configuration Guide.
