Hi, I'm trying to configure a dual PRI card running the 3.1.5 software revision to interface with a 5ESS swith from Verizon but am having some problems. I've only ever configured DMS-100's so I'm not sure if I'm missing anything. I get the D-channel up, but the B's never come up. Also, I have a red alarm light and no carried detect light. If I look at the span stats, it shows the following: Time since clear (days::hh:mm:ss): 0::0:0:39 Receiver Gain: 0.0 dB Errored Seconds: 1 Severely Errored Seconds: 1 Unavailable Secs (freezes other ctrs): 27 Bipolar Violations (LCV): 0 Framing Bit Errors (D4 path code viol): 0 Change In Frame Alignment: 0 Severely Err Framing Secs (oof, ais): 1 Controlled Slip Secs (frame slips): 1 Bursty Errored Seconds (ESF Only): 0 CRC Errors (ESF path code viol): 0 Excessive CRC Error (ESF Only): 0 Out of Frame: N Out of Frame: (Red Alarm): N Loss of Signal: Y Loss of Signal: (Red Alarm): Y Remote Frame Alarm: N Remote Frame Alarm: (Yellow Alarm): N Alarm Indication Signal: N Alarm Indication Signal: (Blue Alarm): N Loop Back: None D-Channel Status: Up Verizon tells me I must configure my end to send them 10 digits. Where do I set this or is 10 digits the default? Also, I believe they have configured the circuit as a 2 way PRI although we only need to accept inbound calls. Any ideas? Any assistance is greatly appreciated. You probably know what it's like dealing with Verizon. Dan Houtz
