PBX Compatibility
n Description
You can connect your phone system trunks to Centrex/PBX lines, rather than to telco trunk circuits.
This makes the trunk inputs into the system Single Line 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, phone system users must
first dial the PBX's trunk access code (usually 9).
The system provides the following PBX Compatibility options:
·
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.)
·
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 phone system provides the restriction, it restricts the
digits dialled after the PBX access code.
·
PBX Call Restriction
When the phone system does the Toll Restriction, it can further restrict users from dialling
PBX extensions. In this case, the only valid numbers are those dialled after the PBX trunk
access code. The only PBX facility phone system users can access are the PBX's outside
trunks.
·
Automatic Pause
The system automatically pauses when it sees a PBX trunk access code during manual
dialling, Abbreviated Dialling, Last Number Redial, Repeat Redial and Save Number Dialled.
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.
Default Setting
Disabled.
