t1#—Number indicating the T1 channel.
channel-group#—Specifies the channel-group number, from
0 to 23.
list-of-timeslots—Specifies one or more time slots.
speed [56 | 64]—(Optional) Specifies the line speed in
kilobits per second. Valid values are 56 and 64.
t1#—Number indicating the T1 channel.
local loopback—(Optional) Loops data from the transmit
path to the receive path.
network loopback—(Optional) Loops data received on the
external port to the transmit path and back out the external
port.
remote line fdl {ansi | bellcore}—(Optional) Sends a
repeating, 16-bit Extended Superframe (ESF) data link code
word to the remote end 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 [fdl] [ansi]—(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.
t1#—Number indicating the T1 channel.
