Pbx Compatibility - NEC UNIVERGE SV9100 Features And Specifications

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 to 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 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 up to four groups of trunk access codes. The codes can have one or two digits,
consisting of the digits 0~9,
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.
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 outside trunks.
Automatic Pause
The system automatically pauses when it sees a PBX trunk access code during manual dialing,
Speed 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
trunk stops sending digits to the central office.
The system automatically pauses after it finds a PBX access code in a Speed Dialing bin.
If Speed 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.
Users answer incoming calls on PBX trunks just like other trunks. All relevant access and
Ring Group programming applies.
Except for dialing the PBX access code, users place calls on PBX trunks just like other
trunks. All relevant access programming applies. Refer to the
feature for more details.
You can have DILs route from the connected PBX. Users can access these trunks for
outgoing PBX calls. All PBX Compatibility restrictions and programming apply.
