| Senior Member  | This posed quite a bit of difficulty. Here is what finally allowed connectivity and external calls to complete. This BVoIP pilot is sitting behind our 81C. The 81C is providing the T1 connectivity to the Call Manager. (We were looking at QSIG but, our switch does not have that package installed.) Anyone have any other notes to add to this scheme? DB15 RJ45 1 = 5 3 = 2 9 = 4 11 = 1 The cable connecting the connector above to the 6608 card needed to have the following: End 1 = 1 2 3 4 5 6 7 8 End 2 = 4 5 3 1 2 6 7 8 The DCH needed to be: USR PRI OTBF 32 PARM RS422 DTE DRAT 64KC CLOK EXT IFC D100 SIDE USR (could not set this to NET so it defaulted to USR) the rest default out The Route needed to be: TKTP TIE RCLS EXT DTRK YES DGTP PRI ISDN YES MODE PRA IFC D100 SBN NO PNI 00000 NCNA YES NCRD NO DSEL VCE PTRP PRI ICOG IAO SRCH RRB TRMB YES default all the way out Then the trunk members were: TYPE TIE CDEN SD TRK PRI PDCA 1 PCML MU NCOS 3 CLS just enter DTN default out Rachelle |

| Senior Member | They wanted me to set up the DCH as the network side and then they would time off of me but, I was never given the opportunity to say what my SIDE prompt would be. It defaulted to USR. The Cisco guy then went and made a change on his side, I can only assume that it was to NET, and we were in business. They ideally want the T1 circuit to come directly from the Telco and not to use the PBX at all. You can understand why. rachelle |

| Senior Member  | Technically, the clocking should always point back NORTH or towards the CO trunks. CO<<-----Meridian<<<-----Cisco Right now you have: CO<<-----Meridian----->>>Cisco and you are susecptible to Slips on the Cisco span since the Cisco box has no carrier clocking source and is basically in FRUN. |

| Senior Member | Ahhh, I see the problem. D100 interface. Since this is designed to be a carrier type interface, the Nortel box does not let you be the NET side. Another reason for going Q.Sig. It is designed to be a peer-to-peer protocol, not a carrier to CPE protocol. |

| Senior Member | Exactly! Unfortunately, my systems don't have QSIG packages. I tried to provide the signalling that the Cisco docs wanted and that was never going to work. They didn't listen so we had to fail to prove the point. Then I tried to implement QSIG and found out that I don't have the package so, I resorted to D100 and they set their GUI to be the NET side. QSIG would have been ideal if only I could produce it. rachelle |

| Senior Member | This seems to be the culprit in the BUG1369 errors. As soon as I took this down the errors stopped. I am 45 minutes without an error, now. So, since my PBX does not support QSIG and D100 was the only thing that Cisco could come up with, does anyone understand the Call Manager enough to answer a few questions? What part of Call Manager (gateway) acts as the Bchannel handler? What part of the gateway acts as the Dchannel? Since the CM is the NET side of the T1 and LCNT is clean what would be the snafu? Thoughts???? rachelle |
