dialing between 2 different systems

[tweege]

i have a client with a toshiba strata at one office, and building another office which will have an avaya partner. i believe i can get dialing between the two systems by going from co trunk port on one system to analog port on the other, and then vice versa. question is, what is the name of the lines the phone company would have to provide for that?

thanks, tim

Off Premise Extension (OPX)

If it ain't broke, I haven't fixed it yet.

Sounds more like a tie line although tie lines are usually similiar to CO port to CO port. IE: Dial access code, fet CO port and dial tone from other system and dial extension or access code. In any other case except VOIP it's usually expensive.

There are 2 ways I have done this. One is to go from our PBX to a wireless phone system we used to have - both on the same premises. I put a T1 card in the PBX and the wireless already had one so I just hardwired the two together, set it up as a trunk group, and set up a block of extensions on the PBX to use the wireless. Obviously anything that wasn't already in the wireless's dial plan it routed across the same trunk group to the PBX. You could basically do this same thing through the outside using a T1 line provided by the phone company, and in that case you would need a CSU on both sides to make the connections.

The other way I've done it, but it was over 10 years ago, is to have one or more leased lines between the buildings (more expensive than T1's now) and set them up as E&M tie lines. In that case we had to dial 83 (so we didn't blow the whole '8' block of numbers) and then the extension. The dial plans on both switches were set up so that if someone dials '83' it sent the digits that followed (the extension) to the other side just like a DID call.

Both of those worked at one point or another for me.

The Partner does not support a DS1 configuration for that type of service. I don't know what the Toshiba can do.

But some of the choices would be Off Premise Stations (OPS) using analogue station/ CO line ports on both systems or, if the CO lines are served from the same CO and switch, you could change them to CENTREX service and access either location using the station-to-station calling and other CENTREX features that may be useful, like call transfer, etc. from the CO lines. No added equipment to buy for CENTREX.

I guess I should have been more clear that this wasn't the same hardware he was talking about, and just general suggestions... Sometimes the phone rings so much it takes 15 minutes to make a simple post here and the distraction sucks - how dare work interfere with my web browsing!!

I do have a DK280 at another site and there are T1 boards available for that, but I've never needed one so I never read up on them and their capabilities.
