Configuring the T3/E3 SPA Port for the Clear-Channel ATM Mode

To configure a T3/E3 SPA port for the clear-channel ATM mode, perform the following steps:
OL-14127-17
Purpose
Selects the E3 controller for the port you are configuring, where slot
/subslot identifies the SPA slot and subslot, and /port identifies the port.
(Optional) For the clear-channel ATM, configure framing as g751, which
is the only framing that is supported.
(Optional) Specifies the length (in feet) of the cable attached to the port.
The valid values are 0 to 450 feet. The default value is 224 feet.
(Optional) Runs a loopback test that is useful for troubleshooting
problems. The no form of the command stops the test. The default
command is no loopback.
(Optional) Configures bit error rate (BER) testing.
Returns to the global configuration mode.

Configuring the T3/E3 SPA Port for the Clear-Channel ATM Mode
• local—Loops the signal from the Tx path to the Rx path. Sends
an Alarm Indication Signal (AIS) to the network.
• network {line | payload}—Loops the signal from the Rx path to
the Tx path. The line parameter loops back the unframed signal
and the payload parameter loops back the framed signal.
