KSU's suck and PBX's don't.

Twisted

The biggest difference to me is that I can spell PBX.

In a KSU world user has to select trunk via a trunk key, in a PBX world trunks are grouped and switch decides best trunk to use via your programmed instructions.

John & Twisted - Thanks - but I don't think those would go over well in a Comparison Chart..

Jack - Would a Nor* be considered a KSU?

I believe the N* is a KSU

C,

Yep!!

Here's a snip from an old letter from Nortel --

February 28, 2002
As General Manager of the Nortel Networks* Local Premise Solutions team, I am writing to update you on our plans
for the Norstar* portfolio during 2002. I’m pleased to be able to tell you that our installed base now exceeds 1 million
systems and 13 million lines, and that Norstar continues to be the market-leading digital key system for small and
medium businesses and branch locations.

Maybe ksu's are typically smaller systems than pbx's

I have been around a long time and on a True key system each phone has a key to access each outside line.Their is also a Intercom key that they can call each other on. So a person would answer a line put it on hold and dial another person on their Intercom key and they would then answer the line.
In a pbx the users have extensions and they dial a code usually 9 to access outside lines
We have some key systems that came out on the market several years ago that are called Hybrid key systems which means they can be programed either as a pbx or a key system.

Chas,

You been spending too much time on the Nortel site... you have forgotten the lore of our original site!!

What's the principle difference between PBX, PABX and KTS?

I think we nailed it pretty well in that thread!
