Enable Loopcodes Example
The following interactive example displays two routers connected back-to-back through an FT1/T1
line:
Router# no service-module t1 remote-loopback full
Router# service-module t1 remote-loopback payload alternate
Router# loopback remote full
%SERVICE_MODULE-5-LOOPUPFAILED: Unit 0 - Loopup of remote unit failed
Router# service-module t1 remote-loopback payload v54
Router# loopback remote payload
%SERVICE_MODULE-5-LOOPUPFAILED: Unit 0 - Loopup of remote unit failed
Router# service-module t1 remote-loopback payload alternate
Router# loopback remote payload
%SERVICE_MODULE-5-LOOPUPREMOTE: Unit 0 - Remote unit placed in loopback
Specify Timeslots Example
The following example displays a series of timeslot ranges and a speed of 64 kbps:
Router# service-module t1 timeslots 1-10,15-20,22 speed 64
