2.7 NETWORKING OVER PRI
The following procedures are intended to show how to set up networking between
systems only. It is assumed that all the systems to be networked together have already
been set up as stand alone systems with LCR and inbound trunks already set up. If
these items have not already been set up then some networking features such as
Tandem Dialing and DID pass through cannot be made to work.
The first thing that must be done if networking is to work is to determine the numbering
scheme for all ports in the total combined network including room for expansion at
each of the networked systems. If the total number of stations is going to be less than
150 then a three-digit station numbering scheme can be easily used (extension
numbers 201 to 349). However if more than 150 stations are required then it is strongly
recommended that a four-digit numbering scheme be used. Doing this will allow all the
systems to have the same feature access codes and will reduce the amount of system
programming.

Hardware Setup

Connection Type
The type of circuit used to connect two OfficeServ systems together is a "point to point"
T1 configured with ESF and B8ZS signaling. The OfficeServ TEPRI card will convert this
T1 into a proprietary type of PRI signaling. If Drop and Insert type CSU/DSUs are to be
used on the circuit so that the span can be used for data as well then the OfficeServ
must have control of channel 24 on the span and voice channels from channel 1 down.
For example, if a customer wants to use 8 channels for data and 15 channels for voice,
then the OfficeServ has to have control of channels 1 through 15 for voice and channel
24 for signaling.
TEPRI Card DIP Switch Setup
On the DIP switch bank on the TEPRI card switches 1, 2 and 8 must be set to the ON
position. If this card is to be the PRI D channel controller card for the span then DIP
switch number 4 should also be in the ON position. There can only be one D channel
controller on each span.
