Hello, Can anyone on the list interpret these error messages? Our telco reports that the chassis is rejecting all calls offered to it. 18:24:31, Facility "GWC Modem Driver", Level "UNUSUAL":: GWCMDM_AL,slot:7/mod:25 TAPI_OPEN failed, retrying At 18:24:31, Facility "GWC Modem Driver", Level "UNUSUAL":: GWCMDM_AL,slot:7/mod:23 TAPI OPEN failed At 18:24:31, Facility "GWC Modem Driver", Level "UNUSUAL":: GWCMDM_AL,slot:7/mod:23 TAPI_OPEN failed, retrying The DSP also reports Span1 Modem Not Available Count is: 2 Does this mean that the chassis is failing to get control of the DSP's? The operational status of each modem is listed as down when doing a list interfaces on the ARC. E.g: Interface Oper Admin Name Status Status slot:1/mod:1 Down Up slot:1/mod:2 Down Up etc for all the slots. Line status parameters reported by the DSP are normal: NO ALARM = TRUE RCV FAR END LOF = FALSE XMT FAR END LOF = FALSE RCV AIS = FALSE XMT AIS = FALSE OUT OF FRAME = FALSE LOSS OF SIGNAL = FALSE LOOPBACK STATE = FALSE T16 AIS = FALSE RCV FAR END LOMF = FALSE XMT FAR END LOMF = FALSE RCV TEST CODE = FALSE OTHER FAILURE = FALSE I have no idea how to fix this and bring the operational status of the modems up. It is on a chassis that we are trying to get working in Germany that was previously used in the UK. We have the switch type set to ICTR4 and the line type set to crce1. We've tried disabling chassis awareness and adding each card to the ARC manually. I was wondering if anyone on the list might have some idea on how we can get this chassis working so the powers that be will let me come back to the UK :-).
