How do I change route trunks?

[joed1228]

In LD 90 I print out a NPA like 1-212 and it gives me a route number. Then I go into LD 21 and do a LTM to see which trunks the calls for 1-212, going out over route 1 (for example) will seize when a user dials out.

I would like to cover my back in the event that a T1 goes down. How do I re-route all of the calls going out over a specific T1 to another?

From what I understand I need to tell the route to use another set of trunks. How do I do that?

-------------

P.S. Are the trunks numbered the same as the loop? Like trunks 18-1 thru 18-24 are always for loop 18 or is it possible that trunks 18-1 to 18-24 could be used for loop 3? If it is possible; how do I know for sure which trunks are associated with which loops?

OK, there is a step in there you need to check. In LD 90, the RLI is providing the Route List Index that a call uses. In LD 86, if you print that RLB, that is the prompt you enter at FEAT, it will return RLI, you will see the route(s) used for that call. These can be the same, but they also can provide multiple route options for a single NPA. so:

LD 90

NPA  1212
RLI 1 <-- This is a Route List index

LD 86

REQ  PRT
CUST 0
FEAT RLB
RLI  1
ENTR 0
LTER
ROUTE 5 <-- This is the actual route the call is presented down first
..
ENTR 1
LTER
ROUTE 10 <-- A second route option
...
ENTR 2
..
ENTR 3

Within the RLI, you can do exactly what you want. In the RLI/RLB printout, you will see ENTR 0, this is the first choice for your call, you can have an ENTR 1, 2, 3, and so on for multiple options. This will check each route for service, then step to the next option. It is also in the ENTR 0 you will see the actual "route" that entry is using.

As for your PS, you can number them any way you want. Some techs do it based on loops to keep things the same, others by frequency used, it just depends.

Hope this helps,

Thanks Scott.

Suppose the customer does not have backup routes but they have another T1 just sitting idle? What commands would I need to take the calls that go out on route 1 from Loop 2 and send them out on Loop 8? I'm thinking worst case here.

As for the trunks, do you know of a command to "list the trunks loop x is assoicated with"? I'm wondering in the event they do no match, like how would I match them up.

What route is loop 8? If it is a different route then loop 1 put an ENTR 1 into the RLI using that route number. Make sure to set FRL the same as ENTR 0.

 

[joed1228]

Is this my answer?

LD 14
REQ CHG
TYPE (ENTER THE TYPE OF TRUNK)
TN (XX X XX XX)
RTMB (NEW RT NUMBER AND MEMBER)

It seems like I can take my DID trunks and make them handle calls for another route?

 

[mluckie1]

Print the TN for 8 1 and see what Route it is assigned to. Then go to LD 86 and chg the RLB so ENTR 1 reflects that route.

(joed1228) Thats not the way to do things. You use LD 86 to change your choices. do a
LD 86
REQ PRT
CUST 0
TYPE RLI
RLI 1

Within this RLI it will tell you what your choices for routing are as srmega41 tried to point out to you.

Post your RLI 1 here so we can help you.


RLI and RDB are not the same thing.

ace is right, you can't change a trunk from one route to another unless a ton of other parms match.. don't change the trunk, just point the rlb to the new route. what i usually do is build a new rlb for testing, then point 1 npa or nxx to that rlb and test.. by picking a less unsed number you can test and change it back without someone knocking on the door.. if you change the only entry in a rlb to a new ld carrier, all you ld could be down for a while. i usually change montana to my mew carrier and dial any number in that state (non 1800), those can be found on a simple google for any type of service in the state

Onr thing that I ALWAYS try to remember is that PRT is your best friend. In your question, do not change anything. Print a TN from the loop you are asking for, and it will show you the route and member it is. From there, you can use LD 21 and do a LTM.

REQ  LTM
CUST 0
ROUTE X <-- route number goes here

This will show you all the members of that route. If you know the route but not the members, like in your RLI issue, you can do the same thing. Printing things out will only help you understand what the PBX is doing. Changing things quickly can get real ugly fast. (Words of experience)

Hope this helps,

Forget everything about TN's, RDB and trunks, your using NARS or BARS and you make your changes in LD 90 and 86.

always listen to the ace, if you need help with ld 86, let us know, one of us can post the code..

Original post In LD 90 I print out a NPA like 1-212 and it gives me a route number. Then I go into LD 21 and do a LTM to see which trunks the calls for 1-212, going out over route 1 (for example) will seize when a user dials out.

Its not a route number, it's a RLI (Route List Block) found in LD 86 Print the RLI and it will tell you what route choices you have. If you print the RLI here we will explain it to you.

 

[johnpoole]

correct, when you do a prt rlb in 86, the entries may have several routes, the 1st match with an frl =to or lower then your ncos and a vacant route, that is not blocked by a tgar/targ match is the trunk you will use...

routing example

two routes in my ld rlb, 1st one has 94 trunks, frl of 3 with an auth code required.. second entry has 23 trunks with an frl of 5 auth code requried..

the reason, it the 1st route is busy and your a big shot, or the telephone man, you can still dial out.. those peoples auth code changes there ncos to a 6, i had to stop ncos 2 users from hitting that route because there auth code changes there ncos to a 3..

not unusal routing, i only use tgar/targ to block 99 percent users from over head page, and courtsy phones from overhead and inhouse page.. those set have free local and no way to access ld.. ncos 7 is used for international for vp's, those users do not need a auth code.. this site is a hospital with 3000 digital sets and 4000 analog phones. all 10,000 numbers are did. of course we can't use 9 or 0 as a 1st digit, but we have those did's so i can use them with a idc for special apps...

guess i get bored on days off
