Using ISDN Config tieing two G3 Systems together

[GTD5]

I am connecting two g3V6si systems together. I am
using ISDN tie trunk/Tandem configuration. when Switch A
accesses the outbound ISDN trunks of Switch B to dial out..
through ars...
Will Switch A's isdn public/unknown format numbering information be transfered to switch B and be sent outbound
on that systems isdn outbound trunks? Are there any
special Considerations?

The ISDN id's from the distant switch will travel with the call through the tandem switch. You should not have to do anything special.

If you do DCS over ISDN D-Chan, then all the better. It will make it possible to use a single voicemail at one site, and allow message waiting activations and such to be system transparent.

If you use DCS in this way, the users will see the two systems as a single PBX.

I managed a similar setup. It made all the routes really easy, since everything had to go through the tie trunk to the tandem switch!

The ISDN data from the distant switch will end up in the CDR of the tandem switch as well, so you probably won't need to do CDR at each site. Just the site connected to the public network.

Carpe dialem! (Seize the line!)
