10.1 CENTREX SMDI OPERATION 
SMDI stands for Simplified >lcbsage Desk Interface and, SM.53 stands for Simplified Message Service 
Interface.’ These are optional -53.ices available on some Centrex systems. They provide a connection 
between Centrex and the VP 5.1 on the customer’s premise. This connection is in the form of a 1320 baud 
serial data link. . 
Calls to unanswered or busy Csntrex lines are forwarded via Centrex call forwarding to the VP IO& 
multiline hunt...

Called Party 
Identification When a call comes to a Centrcs line that is forwarded’ to the VP 100. the SMDI 
sends the call record over the data link to the VP 100. In most cases. the VP 100 
receives the call record Lvithin the first ring of the forwarded call. The VP 100 
answers the call as soon as it rsceives the call record. The call record pro\-ides the 
VP 100 \Lirh the follo\ving information:

CENTREX CONFIGURATION 
Each VP 100 port requires a ZOO-type Ce?trex station extension. The approptiarc number of Centrex 
station lines for the VP 
100 ports must be provided and programmed as a multi-line hunt group (MLHG) 
with ShlDI. 
. 
All stations to be call forwarded to the VP lOO/SMDI ports require ach of the following to be 
programmed at the CO. Adaptive Integration includes both Called Party Identification (CPI) and Message 
Waiting...

10.4 VP 100 CONFIGURATION FOR CENTREX SMDI 
Mailbox and station numbers must match in the USER Table for Message Waiting Indication (MWI) 
and/or Called Party Idenrificarion (CPI) to operate correctly. This is required for the following reasons: 
l For Message Waiting Indication. Centrex activates-and deactivates the XLIWI for the station number 
associated with rhe mailbox. 
l For Called Party Identification. Centrex uses the station number in the SMDI call record to identify the
