We may be facing a situation where we will have to scatter the 4 offices currently on an STS to separate buildings. Not sure how it's all going to shake out yet.

Is there a 'best' way to keep everyone on the same STS? Are there still OPX boxes available? The CO is fairly close and we'll have to work with the LEC no matter how we do this. One of the main problems is the ability to transfer and forward calls, night transfer, etc. as well as the VM issues.

Centrex is not available but even if it was, that wouldn't really simplify things in this case.

What about doing something with multi-plexers of some sort linked by data circuits?

I can't help you much here but you should include how many extensions and CO lines are going to be needed at each location. Another question you will be asked is broadband available in all locations.

Unless you have your own cable between the buildings, you're not going to be able to accomplish this with the STS.

There are no OPX boxes for Digital sets. Even if there were, you would have to account for 911 calling or you could be putting yourself in a high risk/liablity situation.

You could upgrade to an XTS-IP and either use IP phones at the remote locations or seperate XTS-IP systems linked with VoIP cards. That is assuming that you have available broadband or WAN.

You could possibly come up with a way to use SLT via VoIP boxes (such as Muilt-VoIP) but, I wouldn't think you would want to have people using SLT sets.

As Merrit said, please include some more information. But, to connect these buildings together is going to be rather costly compared to the STS.

Have ksu both locations,use dry cable pair from telco..(each location)
use opx module give you about total loop of
6 miles.(loop extender at central ksu)
Access remotes (ksu's) via co port on home base ksu slt port-s
This will give you multiline key sets, and central voice-mail.

Ive done this before with school districts.
Presently have lumber wholesale co. using pan kxt1232 and a Panasonic 624 (works) if your
loop is in
range of spec-s. Assign slt extensions of home ksu to each remote site (via slt card)
This will allow you to call between any site and you may use all features of Mother ksu.
Watch your loop limits on your dry cable pair's.
Make sure you use good line protection on all cable pairs both ends. I used (PROCTOR loop extender's)

TJ,

How would this allow centralized voice mail? Wouldn't that limit them to only one mailbox per remote office?

Otherwise, I thought about suggesting your senerio, only using a VoIP box instead of the dry pairs.

Larry,

That is correct. One (1)
visual vm box. However, you still have access to vm system via the slt port, you would have to dial into vm system using access code.
Maybe not the best set up but what can i say it work's, just have to dial access codes not just one step with msg lites.

Running about 10 COs and 15-20 Stations. DSL is coming soon so I was wondering about the VoIP option but I doubt the cost of that many VoIP phones would pay off. Not sure about linking systems that way.

The voice mail is one issue, but the after hours Night Ring coverage is the bigger issue.

There used to be devices called multiplexers that would link via 4 wire data circuits and give you "X" number of configurable (voice or data) channels at each location, but I'm not sure if they would work in this case.

Just shooting at ducks right now.
