Specifying T1 Framing
In controller configuration mode, specify T1 framing by entering the framing [sf | esf]configuration
subcommand, as in the following example:
subcommand, as in the following example:
Router(config-controller)# framing sf
Use the
no
form of this command to return to the default, ESF framing.
Note
If you specify SF framing, you must have 56-kbps speed or inverted data to avoid errors.
Setting the Cable Length
For the PA-MC-2T1, PA-MC-4T1, and PA-MC-8T1 port adapters, in controller configuration mode, set
the cable length by entering the cablelength [long {gain26 | gain 36} {0db | -7.5db |
-15db | -22.5db} short {133 | 266 | 399 | 533 | 655}] command, as in the following example:
the cable length by entering the cablelength [long {gain26 | gain 36} {0db | -7.5db |
-15db | -22.5db} short {133 | 266 | 399 | 533 | 655}] command, as in the following example:
Router(config-controller)# cablelength long gain26 -15db
Use the
no
form of this command to return to the default, gain36, 0dB.
Note
Each T1 port can operate in long-haul or short-haul mode. In long-haul mode, the user must specify the
gain and the line build-out. The default values are gain26 with 0dB line build-out. In short-haul mode,
the user must specify the cable length in feet. The range is from 0 to 655 feet. The actual mapping is
shown in

For the PA-MC-8DSX1 port adapter, in controller configuration mode, set the cable length by entering
