1613-Loop Control

Description

Use this program to adjust timers that affect the loop on the line (COIU) PCBs.

Options

1613-01: Loop Current Detection Timer

(Loop Detect)

For loop start lines, loop current must be present for this interval before the system seizes the line. Set this interval for compatibility with the connected telco or PBX/Centrex. If you set this interval too short, the sys- tem may inadvertently seize unstable lines. If too long, the system may not properly seize a valid line.

1613-02: Far End Disconnect Timer

(Clear Signal)

Use this option to set the loop disconnect interval for outside calls. If the system detects a loop current inter- ruption longer than this interval it assumes the telco has disconnected the line. It then returns the line to idle. Set this interval for compatibility with the connected telco or PBX/Centrex. If you set the interval too short, lines may not properly disconnect when the far end hangs up. If you set the interval too long, the system may interpret momentary loop current interruptions as positive disconnect.
