I can not access my DSC from the PSTN. 1

[RahjiSupreme]

I have a DSC built for 5010-5019. The DSC is meant to send calls to these extensions to a TIE trunk, which connects to a Cisco router and a fax server. If I dial the DID internally, the calls complete. If I dial from an external telephone using the npa nxx, the calls will not complete. The call does not even hit the trunk, I've ENL MSGI on the dchannel and get nothing. Is it because I'm attempting to send the call to a DID trunk? My TIE trunk is built as a DID trunk between my Opt 61C PBX and the Cisco router. I've done this before with the trunk being built as a TIE trunk, but for some reason, the PBX will not let me build the trunk as TIE NI2 anymore. Any assistance would be appreciated.

 

[EddieDuece]

Do you have those numbers CDP'd correctly. Sounds like their hitting the opt. 61 and have no where to go from there?

 

[johnpoole]

works internal but not external.. look at the dsc and maybe change that frl to 0 or change the ncos of the inbound trunk.. either that or remove the targ 1 (default) on both of the routes.. x1 removes it..

if the targs match on the routes it's a natural block... if the frl of the rlb is higher then the ncos of the inbound trunk it can block

I'm sending the CDP DSC 501 to RL6, which uses Route 4. Route 4 is a DID route to a CISCO 5350 router.

Have you removed the Targ on the route yet? Do that and give it a try as John suggested.

What does your IDC table look like? Can you print that out and post it?

 

[RahjiSupreme]

I removed the TARG and it still doesn't work. I don't use a IDC table. But here's my route.

What is the NCOS of the individual trunks????

 

[RahjiSupreme]

NCOS is 5 on the trunks.

 

[TAnselm]

I probably should have made myself more clear...

Check ncos of incoming trunks.

Then go to ld 87 prt nctl to find out what frl that relates to.

then check in ld 86 under the rlb to find out what frl is require to access the tie trunks. This is to make sure that your incoming trunks have a ncos high enough to access the outgoing tie.

You may want to lower the frl in the rli for the outgoing tie trunks.

 

[johnpoole]

ncos is usually a factor after using ac1 or 2.. but the dsc does go to a rlb with an frl.. i feel it will either be ncos or targ/tgar

The DID trunks do not give me an option to set the TARG. On a TIE trunk I can set the TARG. In the past I was able to build a TIE NI2 route. Now I can not. I get an error at the CBCR prompt. It no longer accepts the default "no". Now you have to input "yes". Then it wants to know the RTN, which is not built. The error codes are sch0520 and sch0176. I think the problem is that I can't get the TGAR and TARG correct, because I have DID trunks instead of TIE trunks. Any suggestions around the CBCR and RTN crap??? This must have been a change Nortel made after an upgrade, bc I built some TIE trunks in 2003 and didn't have this problem.

look at the route for targ

[TAnselm]

If you took the default on programming it definitely could be a TARG/TGAR matching problem.

 

[johnpoole]

he posted the route and it was default tgar.. nortel defaults all routes and sets to 1 so they are not responsible for toll fraud.. unless someone changes the default, no one can dial tandem

If anyone is still reviewing this post, the easiest way to get the TIE trunk to work (inbound and outbound) is to build it as a QSIG trunk. With the newer release CBCR prevents building a TIE NI2 trunk. A DID trunk will not allow the CDP to work from trunk to trunk. SO A QSIG trunk is the only option I found that works.
