I have a G3si rel 6.0,having trouble getting the PRI to connect. Telco has checked and verified that the circuit is working correctly. I have tried an Avaya cable, terminating on 110 hwde using the following connectors 47 LI (high) 22 L1, 48 LO, 23 LO (high). "D" channel is floating up and down, "b" channels indicate OSS-FE-PIN-IDLE. PRI permission "Y", "D" channel is 01A1524, replaced TYN 464F, no change is state.
