1631-01: Receive Loop Detection Timer [System: Timers: T1 Card: Incoming (1631): Rx Loop Detect]

For loop start T1 lines, loop current must be present for this interval before the system seizes the line. Set this interval for compatibility with the T1 service provider. If you set this interval too short, the system may inadvertently seize unstable lines. If too long, the system may not properly seize a valid line.
