PBX Compatibility

• 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 0).
The system provides the following PBX Compatibility options:
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.

•
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 sys-
tem 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.
