RLIs and ROUTs 1

[chancal]

Hello everyone,
Please help, i just can't seem to get my head wrapped around this concept.
So this is my understanding...
you have an RLI that points to a certain ROUT. This ROUT is associated with a certain pri and that's how you direct certain calls out your various pri's.
So here's where i get confused.
I do a ld 86, prt, rlb to see all my RLIs and their ROUTs.
Not one shows a rout of 50 which is what my pri is.
Can someone layout exactly what leads into what?

thanks

NPA/NXX/SPN

RLI

RDB

Trunk Members


Routes is built, then trunks added to route, then RLI is built and route is assigned to the RLI. Then NPA/NXX/SPN is built and a RLI is attached to it...that's the very basic

Do a TNB on 50-1 and it will give you the route asscoiated with that PRI loop.

Your route 50 is likely a master route for ISA or Call-By-Call trunks. The master route will have service routes associated - SVRT in the RDB. The service routes have no members assigned but reference the master route.

ok.
i have 2 loops this site.
I can see exactly how 1 loop gets used (it's a tie line) but i cant see how the other loop, which is my pri, is used. Does everything hit this "main pri" loop by default somewhere(which is why it doesnt show up in a LD86 prt? and my tie line loop will only get used if there is an rdb for it?
Basically this is what im trying to do...
We are going VOIP and want to consolidate all our PRIs into 1 building. Each site PBX will be connected to their respective gateways via a tie.
So, when this project is complete each PBX will only have a tie line connected to it.
I need to figure out how to tell each PBX to start directing all voice traffic through the tie loop and not the pri loop anymore, obviously because there wont be any more local pris at each site.
hope that makes sense.

Check out GHTROUTS BARS and NARS

http://www.ghtrout.com/bars/index.html

really good basic info to help you understand. . .

just read thru GHTROUT's thing and it is making sense finally.
so i did a print of all my NPAs and they all use the same RLI. i do a LD21,LTM and find this:
TYPE TLST
TKTP COT
ROUT 9
DES CBCT_OUT

Any ideas what this is?

I hear what youre saying StanleySteamer, but my logic is telling me that my NPAs would be point to an RLI that would use my ROUT 50.

 

[StanleySteamer]

Think of route 50 as a pool of trunks that are accessed by service routes.
Route 9 is your main outgoing service route but it uses the trunks in route 50.
You probably have an incoming service route that also uses the trunks in route 50. So the trunks are shared by two or more service routes. Print the RDBs in LD 21 and look at SVRT and RTN and you will see the connection.

you can trac 0 acod of a route to see how many trunks are connected.. a rli is a roadmap.. i dial numbers, the rli directs me to a route... a route data block is a folder, it contains trunks with the same attributes and a common usage..

you could have a route data block for each trunk..

if i see a rdb that is not used in 86, i check direction, iao prompt, could be just inbound.. then i would look at my other routes at the step prompt.. could be used as an overflow, although that would be a backwards way to route traffic.. you can trad x x trunks to see what traffic it is passing..last choice dis dch x (96) disl x (60).. wait for someone to complain... merry christmas

Wow. that makes perfect sense to me now. it only took me 1 weekend, 2 xmas parties, and lots of rum and eggnog for my brain to process what you guys said haha.

So... this is what i will do,
in LD86, chg - rlb - entr 0 etc - and point it to whichever routs i need to. Sound about right?

 

[johnpoole]

correct, IF you want to change the 1st choice.. you process entry 0, if that route is blocked by frl or all trunks busy, then entry 1 comes into play

Yes, currently the rlb probably points to your COT service route for your main ISA route 50.

Change entry 0 to the tie route and your done.
