What to do if signaling is not functioning correctly on GE JungleMUX 86445-31?
- RRyan BrownAug 14, 2025
If the signaling is not functioning correctly on your GE Multiplexer, ensure that the proper signaling type is selected at both ends. Also, ensure that neither signaling direction is in test, meaning both Transmit Signaling and Receive Signaling fields in Test Setup window are set to '-' at both ends (or, if JCI is used, both Transmit Signaling and Receive Signaling fields in Signalling Setup window are set to 'NRML'). Finally, ensure that the sub-board (028-86445-04) is installed on the unit's main board. Note that the sub-board must be removed if external talk battery and ringing generator are used.
