    Mysterious analog trunk seizure

    bwonders New Member

      I have a 7100 at a customer premise that occasionally seizes one of the analog lines and will not release it until physically disconnected from the jack.  Once it is reconnected, the unit operates as expected until it seizes the line again.  It's an annoyance, and I haven't been able to pin down the issue, as it is intermittently happening.  Does anyone know of a potential reason for this?

          Verify that the 7100 is connected to earth ground, preferably to the same grounding point as the incoming telco protector at the demarcation point. Reversing the polarity of the line may also help. It could be bad hardware. If you swap the problem line with a different one, does the problem follow the wiring or stay with the physical port?
