[comp.dcom.lans] Intecom CBX Ethernet???

cmilono@netcom.UUCP (Carlo Milono) (10/19/90)

Does anyone here know about the Ethernet support over the Intecom
CBX (that's a fancy term for Computerized PBX, a phone switch)??

I am dealing with a situation where the PBX supports a funny box that
has an AUI connector one one side and twisted-pair on the other...it
is *not* 10BASET, however; it seems that it is programmed on some
digital line card on the PBX, but cross-connect work is also required
at the central field.

I am supposing that this beast does sub-rate modulation and actually
transmits/receives at 64K (possibly 56K).  It is a distinct wire run
from the telephone's wire.

If you do have some experience with this arrangement, I have the following
questions:

1) How is it administered - are nets segmented in software?  
2) What cross-connects are required and why? I can understand the PBX-to
   -outlet wiring, but I was led to believe that other work was needed.
3) What is the acutal throughput (carrier) of such an arrangement.
4) Bugs and Cost.
