Optional Tasks
The following configuration tasks are optional
when you configure a T3 controller:
- Specify a cable length.
- Change the clock source.
- Change the framing format.
- Enable or disable SNMP link status processing.
- Assign a text description or an alias to the interface.
cablelength
- Use to adjust the transmit power appropriate to the length
of the T3 cable.
- Specify a cable length in the range 1–450 feet.
- The router supports two transmit powers, one for a cable
length 1–225 feet and another for a cable length 226–450
feet. Therefore, it is not necessary for you to know the exact length
of your cable. You only need to know if the cable length is greater
than 225 feet. For example, if your cable size exceeds 225 feet, specify
any number greater than 225 (and less than 451).
- Example
- host1(config-controll)#cablelength 300
- Use the no version to restore
the default value, 0 feet.
- See cablelength.
clock source
- Use to configure the transmit clock source for a T3 controller.
- Configure one end of the line as internal and the other end as line.
- Specify the keyword line to
use a transmit clock recovered from the line’s receive data
stream.
- Specify the keywords internal module to use the line module’s internal clock as the transmit clock.
- Specify the keywords internal chassis to use the router’s clock
as the transmit clock.
- Example
- host1(config-controll)#clock source internal
module
- Use the no version to revert
to the default, line.
- See clock source.
description
- Use to assign a text description or an alias to a channelized
T3 interface.
- You can use this command to help you identify the interface
and keep track of interface connections.
- The description or alias can be a maximum of 80 characters.
- Use show controllers t3 to display the text
description.
- Example
- host1(config-controll)#description toronto
ct3 interface
- Use the no version to remove
the text description or alias.
- See description.
framing
- Use to configure the framing format for a T3 controller.
- Specify either m23 or c-bit framing.
- Choose the framing format that is compatible with the
framing format of the Telco network device at the other end of the
line.
- Select c-bit framing if you intend to configure MDL messages.
- Example
- host1(config-controll)#framing c-bit
- Use the no version to restore
the default value, c-bit.
- See framing.
snmp trap ip link-status
- Use to enable SNMP link status processing on a T3 controller.
- Example
- host1(config-controll)#snmp trap link-status
- Use the no version to disable
SNMP link status processing.
- See snmp trap ip link-status.
