B2 DN Conflicts

[alycera]

MICS 4.0 with PRI for PSTN, T1 for tie lines and NAM voicemail. I'm trying to add a destination code that will pass any 5XX number over tie lines to another facility. We're currently doing this with 4XX numbers to a different facility. (Our office is 3XX) Trouble is when I go to add the destination code, it won't take it. I don't have any regular DNs in that range. When browsing for the conflict, I went into Port/DN status and started looking at the B2s and found many numbers in the 5XX range. I confess ingnorance on the function of B2 DNs. Since we don't seem to be using them, is it safe to disable the B2 side? Would that free these numbers up to use as destination codes?

Thanks in advance . . .

I know that will be a big job but to resolve your problem for a long time i suggest to you ti change your DN number to four digit...

It's always suggest for all new installation to setup your system to 4 digit.

If you can't do it, you should use to change all your B2 DN's extensions to an other range one by one...

Good luck!

You can change dns.
Change the 5xx b2 dns to 2xx - there must not be anything associatied with the 2xx dns to avoid the conflict.

Ah yup, Lowradiation has it. 5xx's to 2xx's. And Rapetou's 4 digit theme is good policy too, when you can.

And I thought I was the only one geeky enough to haunt the Norstar forum late at night!

I think I'll go with changing the b2 DNs. I only have 30 or 40 conflicts. That'll be a lot eaiser than teaching a new dialing plan to folks at three sites!

BTW - what do b2 DNs do anyway? I saw on the Port/DN status the option to disable. Would that work?

You can basically get 2 connections for the price of 1 in a way. It is a second channel multiplexed on. Some devices need the B-2 to get data across. Some devices like the SMDR use the B-2 for data stream. The DVC's in the NAM use both channels to get the use of 2 channels from 1 port. It varies from device to device.
You can look at the ports in Maintenance to see what they are being used for. I would not disable them. They will show unequipped for normal sets that only need the B-1 channel.

Thanks folks! You're always knowledgeable and helpful. I'll move on those changes tomorrow.
