I have a 1760 at our remote mfg facility. We are connected via a p2p T1. In the 1760 installed are a 1DSU T1, 2FXS, and 4FXO modules. The 2FXS is slot 2, and port 1 is connected to an overhead night-ringer.
The port is part of a pickup groug that every call to the facility should cause the night-ringer to activate. This does not happen.
I've tested the ringer unit itself and it does work. The status light on the 2FXS module is green. When a call is placed to the pickup group the port light does not illuminate.
What might be a cause, or where do I troubleshoot from here?
