A question about MM710BP PRI cards that are fitted into G450 media gateways.

[Richard_Harrow]

So I've been kinda getting my hands dirty with Aura a lot lately and I have one question which is how does the CM know which gateway has which PRI card? So when I hit list con all on the CM(Release 10.1), I see MM710BP along with the channels of the card, but my question is, how does the system differentiate between a PRI card on two separate gateways? Like let's say, I want to have two trunk-groups, PRI-1 and PRI-2, how do I go about doing that? What is the exact configuration process? Could someone provide me some sort of detailed guide or something for my ease?

That's a tall order. Here's some of the basic steps but I strongly encourage you to A) Look at existing information in your PBX to get familiar and B) Head to Avaya Support and read up on the manuals.

Each board must be added to CM. add ds1 [board] for the DS1 Circuit Pack.

add ds1 001v3                                                   Page   1 of   2

You'll need to work with your provider to determine all the settings.

Then you create a signaling group and trunk group for the circuit. While the signaling and trunk group numbers don't have to be the same, it's easier to read if you use the same number.

In the US, the D-Channel is 24 so you would enter "001v324" for this example.

add signaling-group 1                                           Page   1 of   5
                                SIGNALING GROUP

                                                   Trunk Group for NCA TSC:

add trunk-group 1                                               Page   1 of  21
                                TRUNK GROUP

Group Number: 1                    Group Type: isdn          CDR Reports: y

Starting on Page 5, you need to add the individual ports that will be part of this trunk. Typically in the US it will be ports 1 through 23:

add trunk-group 1                                               Page   5 of  21
                                 TRUNK GROUP
                                      Administered Members (min/max):    0/0
GROUP MEMBER ASSIGNMENTS                  Total Administered Members:    0

       Port    Code Sfx Name        Night           Sig Grp
  1: 001v301  MM710  B
  2: 001v302  MM710  B
  3: 001v303  MM710  B

This is really just the basics but I hope it helps.

This is the nomenclature for media gateways:
GGGVSPP

GGG = MG# from 001-250
V = Always V
S = slot# from 1-9 (note that 9 is a virtual slot reserved for the virtual announcement module)
PP = port on said slot from 01-24 (32 if you have your MM710B set for E1, 64 for slot 9 if virtual announcement module enabled)

Hope this helps.
