test interface inband-payload-loop
Syntax
test interface inband-payload-loop (ansi (initiate | terminate) | bellcore (initiate | terminate) t1-fpc/pic/port <:channel>)
Release Information
Command introduced before Junos OS Release 7.4.
Description
Send commands on a T1 interface to initiate or terminate a far-end payload loopback using either an ANSI or Bellcore FDL command code. If the far end of the connection is in C-bit parity mode and has been configured to accept payload loopback requests from the near end, the far end executes the request.
 | Note: The following restrictions apply to this command:
|
Options
ansi | — | ANSI FDL command code. |
bellcore | — | Bellcore FDL command code. |
initiate | — | Initiate the far-end payload loopback. |
terminate | — | Terminate the far-end payload loopback. |
t1-fpc/pic/port <:channel> | — | Name of a T1 interface. The channel number indicates a channelized interface. |
Additional Information
See the ANSI T1.107 specification for more details.
