PBX Compatibility 2 - 653
PBX Compatibility
Description
You can connect your telephone system trunks to Centrex/PBX lines, rather than to Telco trunk circuits.
This makes the trunk inputs into the system 500/2500 type compatible Centrex/PBX extensions, rather
than Telco circuits. PBX Compatibility lets the system be a node (i.e., satellite) in a larger private
telephone network. To place outside calls when the system is behind a PBX, telephone system users
must first dial the PBX’s trunk access code (usually 9).
The system provides the following PBX Compatibility options:
J
PBX Trunk Access Code Screening
The system can monitor the numbers users dial and screen for PBX trunk access codes. The
system can screen for up to 4 groups of trunk access codes. The codes can be one or two digits
long, consisting of the digits 0~9, # and
, . (You use Line Key 1 as a wild card entry.)
J
PBX Trunk Toll Restriction
The system can provide the Toll Restriction for the PBX trunk, or restriction can be handled solely
by the connected PBX. If the telephone system provides the restriction, it restricts the digits dialed
after the PBX access code.
J
PBX Call Restriction
When the telephone system does the Toll Restriction, it can further restrict users from dialing PBX
extensions. In this case, the only valid numbers are those dialed after the PBX trunk access code.
The only PBX facility telephone system users can access are the PBX’s outside trunks.
J
Automatic Pause
The system automatically pauses when it sees a PBX trunk access code during manual dialing,
Abbreviated Dialing, Last Number Redial, Repeat Redial and Save Number Dialed. This gives the
connected PBX time to set up its trunk circuits.
Conditions
When using Account Codes, do not use an asterisk within a PBX access code. Otherwise,
after the
, , the trunk would stop sending digits to the central office.
The system automatically pauses after it finds a PBX access code in an Abbreviated
Dialing bin.
If Abbreviated Dialing routes a call to a PBX trunk, it does not automatically insert a PBX
access code. It outdials the digits just as they are stored.
