Understanding T1s, Trunk Members, Routes in a more visual way. 2

[aztelefono]

Greetings

I understand the concept of BARS/NARS but I am getting stuck understand the relationship between a physical T1 line (its 24 channels, 23 voice and 1 data), how a trunk member relates to it, a Rout, RLBs and all. Basically, I have a downed T1 circuit that goes to NY and it looks like this:

ROUT 27
DES NY

So I thought that since a T1 has 24 channels one could only build 24 trunk members but I see that this is not the case; and thus, this where I get confused. Can someone please enlighten me or point me in the righrt direction?

Thanks!

you can have mant T1 circuits in the same trunk group, in your example loop 18 is the first 23 channels in that plus it has a d channel, then loop 2 has 23 channels and then loop 3 has 24 because it is in a group with loop 18 probably as the primary D channel then loop 2 as a backuip d channel

Thanks,

Thanks for the reply Buddy!

So multiple T1s can reside in one trunk group, OK there.

Now, what about trunk members and routes? What is the relationship between them? So we have routes and then route members; how are these related to a trunk member - or are they not?

A T1 circuit (or many) going into the facility:
We build a ROUTE for this (or several other) T1.
We build TRUNKS (trunk routes or trunk members?)
We build ROUTE LIST.

Herein lies my confusion, in understanding what is what and how it relates to one another. Perhaps it's just with semantics/terminology.

When you build the trunks for a route they become route members. The route is assigned to a route list data block.

the trunks are route members, TN 18 1 is route 1 memebr 1. The routes are assigned to a RLB so NARS/BARS "translations" can be assigned to them. You can PRT an NPA (area code) in LD 90 and you will see it assign ed to a RLB so id you look up NPA 1212 and it is assign ed to go out RLB 1 and you look at RLB 1 in LD 86 you will se what route the RLB is designated to send the call out

Thanks,

Buddy
