Currently I'm working in a Cisco/Nortel integration using an E&M Trunk Card on the Nortel Side (NT8D15AK) to a VIC2-2E/M VIC card on a Cisco 2851. After trying all possible pinouts it is still not working.
Is there anyone that was able to use this particular type of integration.? As a pinout reference we are using the following Cisco white paper:
But when dialing from Nortel site to Cisco we can see the channel going to busy state on the nortel site but remains onhook on the Cisco router. Dialing from Cisco Router doesn't change the idle state on the Nortel EM Trunk Card. Currently we are using EM 4-wire and Immediate Signalling. Nortel is configure as EM Type 1 and Cisco as EM Type 5.
Any ideas? Hints?
Thanks in advanced,
