Example:
•
network loopback
—
(Optional) Loops data received on the external port
to the transmit path and back out the external port.
•

}
—
(Optional) Sends a repeating, 16-bit
Extended Superframe (ESF) data link code word to the remote end
Example:
requesting that it enter into a network line loopback. Specify the ansi
keyword to enable the remote line Facility Data Link (FDL) ANSI bit
loopback on the T1 channel. Specify the bellcore keyword to enable the
remote SmartJack loopback on the T1 channel.
•
remote line inband
—
(Optional) Sends a repeating, 5-bit inband pattern
(00001) to the remote end requesting that it enter into a network line
loopback.
•
remote payload

—
(Optional) Sends a repeating, 16-bit ESF
data link code word to the remote end requesting that it enter into a network
payload loopback. Enables the remote payload FDL ANSI bit loopback on
the T1 channel.
Shuts down the specified T1 channel, where:

—
Number indicating the T1 channel.
Configuring E1 (Channelized T3/E3 mode)
From Cisco IOS XE Release 3.1.1S onwards, E1/E3 channelization modes are supported on the 1-Port
Channelized OC-12/STM-4 SPA.
Note
E1 configuration must be done in channelized DS3 mode. To configure E1, complete the following steps:
