Meridian 1 and VWIC2-2BRI integration

A few years ago I had tested integration between Nortel Meridian 1 PBX and Cisco CallManager 3.1 using router with voice card.

I found my notes from that implementation, as I remember discovery of that solution was pretty difficult.

1. Config on Cisco GW using H.323 was pretty standard so I skip that detail.

2. Meridian 1 PBX requires specific card – in that case it was 8 ISDN ports card – SILC NT6D70.

3. Another step it’s to configure Meridian 1 under LD27 as below:


REQ NEW
TYPE DSL
DSL 8 0 1 0
APPL BRIL
DES BRI
CUST 0
MODE NTFS
B1CT VCE DTA
B2CT VCE DTA
LDN NO
XLST 2
MTEI 8
MCAL 16
MTSP 8
LAPD 2
PRID 2
PDCA 3
FDN
EFD
HUNT
EHT
TGAR 0
NCOS 7
SCPW
SGRP 0
CAC_MFC 3
CLS UNR ICDD CDMD MRD UDI ABDD PGND

REQ NEW
TYPE TSP
DSL 8 0 1 0
USID 0
SUPL_SVC
DN 3992
CT VCE DTA
MCAL 4
CLIP YES
PRES YES
COLP NO
TRANS NO
FEAT HTD FND SFD CFTD MWD FBD HBTD CFXD DN03 DNDY
SSRV_ETSI
DN
DFDN 3992

4. At this moment ip phones should be reachable under e.x. 3992 extension. If needed change IDC as I remember under LD49.

5. Another step is to bind SILC ports to one trunk and attach to trunk (LD15, LD16) with a range of extensions 10 or 100.

Nortel Merdian 1 is almost an antique, but from time perspective comparing to other vendors PBX this one is outstanding, so it still may be helpful to use a solution as above.

CCIE Voice Lab

I saw a scheme how the lab looks like for CCIE Voice Lab exam. At least it is easier to learn build something similar to test, learn and troubleshoot most common issues and implementation tasks.

All looks clear except new version contains Cisco Presence – new to me – never implemented, never supported – yet. Secondary I wonder how important is Exchange server during lab exam. I hope it is just a tool to check some functionalities.
