interface t1 id diagnostic mode { local loopback normal remote loopback send { all ones blue alarm loopback } }

show interface t1 id diagnostic mode

This command sets or displays the diagnostic mode for the specified T1 interface. Specifying local loopback puts the near end in local payload loopback mode. Specifying remote loopback instructs the far end to put itself in payload loopback mode. Specifying send all ones or send blue alarm (which are synonyms) causes the near end to start sending an all-ones pattern, which puts the far end in the red alarm state, causing it to send back a yellow alarm. Specifying send loopback causes the near end to begin sending loopback packets. Specifying normal cancels the effect of any previous diagnostic mode command.

After issuing the diagnostic mode send loopback command, the loopback progress can be monitored by issuing the loopback status command (see below).
