Meridian 11c and asterisk interconnection using PRI

[lexer]

Hi, I've got a Meridian 11c rls 25.30, I want to interconnect the 11c with an asterisk using a NTAK79BA PRI card (in 11c) and A108 Sangoma card (in Issabel Asterisk), please Could somebody help me with 11c parameters: ld 17 - D channel, ld 16 Rout, ld 15 NET, ld 14 TIE port, ld 73. And If somebody has tried this configuration in asterisk can post it

Hi, for testing I created one channel on PRI card and make a loop in BNC (PRI cable) but It appears as MBSY:

>ld 60
.stat 5

I cannot enable D channel in ld 96, I receive error DCH010:

HI, I tried

>ld 96

.enl dch 5
DCH1019 5 0058F6AC 00000003

The ifc is not going to be an SL1 more than likely what are your options in the asterisk? That will have to match on both slides

 

[MossEng]

The command to enable D-Channel is ENL DCH 5 Not DCHI
Normally you don't need to enable D-Channel, when you enable the loop in LD 60 it also enables the D-Channel
Are you sure you've got the correct PRI Card, NTAK79 is DASS/DPNSS & Nortel Propriety QSIG (Networking between Meridians)
The NTBK50 PRI Card with a NTBK51 Daughterboard & NTAK20 CC Daughterboard is normally used for standard QSIG/Euro ISDN connections.

BTW you cannot establish layer 2 on a loop, DCH says hello I am the A end it loops around and the PABX says me too! ISDN usually gives "Release wrong mode" to tell you this.

 

[ThansenII]

check this out:

https://pbxbook.com/meridian/install/pri_prog.html

it tells you how to set it up and the proper interface to use.

keep in mind that when you going to connect directly to an other system you should cross your PRI cable. 1245 <with> 4512
