[comp.dcom.telecom] Need Advice on Choosing PBX System

casbs@csli.stanford.edu (Lynn Gale) (02/23/90)

In the midst of planning for a LAN we also need to make some decisions
about a new phone system.  In the case of digital phone systems, I
take it that data and voice will even share the same wires, given the
appropriate equipment.  Hence it seems important to integrate plans
for computers and phones.

The question is: where does one go for information, reviews, and
comparisons of the many phone systems available?  And in particular
their possible interactions with data networks?  What are the trade
magazines of interest (understandable to the non-expert in
communications)?  Are there relevant b-boards?  Anyone know how to
locate good advice or a helpful consultant?

The Yellow Pages reveal an overwhelming number of companies ready to
install this or that particular phone system at one's site.  But where
does one go to get the broad view of choices / contingencies (minus
the sales pitches)?

Anybody have favorable experience with a PBX suitable for a mid-size
site with little or no expansion needs (approx. 76 stations, 24
lines)?  Any positive or negative impressions regarding particular
telecommunications companies in the Silicon Valley area?


Thanks in advance.

If you're sure that you want a digital PBX and you'll need 24 trunks
and 76 phones, you're farther along than most customers are.
 
In you plan on installing a LAN there likely isn't any need for
simultaneous voice/data. That feature is normally used by companies
that have computers located throughout their location that need to
occaisionally communicate with each other.  If you know you'll be
putting in a LAN then you're best bet is to keep voic and data wiring
separate.

You may want to survey your present staff to determine what they like
about your present phone system and what they don't like. Put a
wish-list together that includes all features desired, even if you're
not sure if they're possible.  This list will allow a seller to
determine the best make and model of equipment for your needs and
wants.

To get familiar with makers and applications I suggest you read
Teleconnect Magazine. Your local library should have it.
 
As for the makers I suggest you look into: Mitel - The 200 series with
Generic 217 or above software.
 
The Mitel SX-50 would also fit well, but if you have 24 trunks you may
want to look into T1 service. The 200 series with 1003 software would
work well and likely save you money using T1.
 
The Fujitsu Focus series is also worth a look, tho with the tariffs,
this equipment may be hard to get or more expensive than it should be.
