Configuring the T1 Idle Cycle Flag
By default, a T1 interface transmits the value 0x7E in the idle cycles. To have the interface transmit the value 0xFF (all ones) instead, include the idle-cycle-flag statement at the [edit interfaces interface-name t1-options] hierarchy level, specifying the ones option:
[edit interfaces interface-name t1-options]idle-cycle-flag ones;
To explicitly configure the default value of 0x7E, include the idle-cycle-flag statement with the flags option:
[edit interfaces interface-name t1-options]idle-cycle-flag flags;
