CENTREX CONFIGURATION

Each VP 300 port requires a 2500-type Centrex station extension. The appropriate number of Centrex
station lines for the VP 300 ports must be provided and programmed as a multi-line hunt group (MLHG)
with SMDI.
All stations to be call forwarded to the VP 300/SMDI ports require each of the following to be
programmed at the CO. Adaptive Integration includes both Called Party Identification (CPI) and Message
Waiting Indication (MWI) features.
•
All Centrex lines that forward to the VP 300 must be programmed by the CO to generate a call record
over the SMDI link.
•
The lines must also be programmed to forward to the VP 300 multi-line hunt group on the desired
condition.
- Ring no answer forwarding to the SMDI group. (For Called Party Identification)
- Busy Forwarding to the SMDI group. (For Called Party Identification)
- C.F.U.S. (Call Forward Unrestricted Source) This enables internal call forwarding to follow the same
routing as external forwarding. (For Called Party Identification)
The following applies to 1AESS and some DMS 100 central offices:
Do not forward a station/extension to another station that subsequently forwards to the VP 300.
The SMDI record shows only the last station that forwarded before going to the VP 300 hunt
group, and the prompt gives that last station number, not the original number dialed.
However, for some DMS 100 central offices using BCS 30 software, or higher, and for 5ESS
central offices, sequential forwarding is supported, and the call record will reflect the originally
called extension.
•
Phones that have mailboxes on the VP 300 should be set up in the Centrex switch to have stutter dial
tone, if MWI is desired. (For Message Waiting Indication)
