Running Loopbacks; Atm Pvc Commands; Specifying A Protocol - Cisco 10000 Series Configuration Manual

Chapter 1 4-Port OC-3/STM-1 ATM Line Card Configuration
The following example directs the router to switch to internal clocking when it receives an S1 SONET
overhead byte with a value of 0xF:
pos flag s1-byte rx-communicate
The default for the pos flag s1-byte rx-communicate command is disabled or off.

Running Loopbacks

Use the loopback command to run a loopback diagnostic tests.
