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 group. The SMDl/SMSI feature provides the VP 100 with the number of the forwarded 
Centrex iine and the condition i-pon which it was forwarded_ 
l *- 
The Centrex must be equipped :i-ith Simplified Message Desk Interface (SMDI) or Simplified Message 
Service Interface (SMSI) for ?WI and CPI to operate. 
This chapter refers to SMDI. brlr also applies to SMSI. 
U35 As of this publication dat?. SMDI is available on the AT&T 
1 AESS, the Northern Telecom SL- 100. 
and the Northern Telecom DMS 100 central office (CO) switches. SMSI is available on the AT&T 
SESS. Even if the switch ii a IAESS, SESS, SL-100 or DMS 100, SMDI or SMSI may not be 
avaiiabie at a particuiar hsstion. Inquire with the RBOC to see if SMDI/SMSI is available and at what 
cost. The RBOC may reqL?c the stations associated with the SMDI/SMSI link (the VP 100 ports) to 
be in a UCD group. In adtirion, there is an installation charge associated with the UCD feature and a 
one-time charge associate2 with each station in a UCD group. There is also a small monthly charge for 
the UCD. 
Fujitsu Focus 9600 PBX- dso use the SMDI protocol_ 
Intercom IBX and Telari PBXs use a protocol similar to SMDI. Since these PBXs send call records 
with ASCII periods (_) pr-?ding the station number, use the PREFIX DIGITS Table to remove the 
leading ASCII periods. 
I As stated in the Bell Car-:.inications Rssrxch Technical Reference TR-TSY-000283: “The word sin~~lified ar used to 
describe this feature. dew :..x imply that there is an alternate feature that is more complex or comprehensive. It ir only 
used to emphasize the sLz;.:zity of the design.”

Figure 10-l The VP 100, SMDI, and Centrex Connection 
Figure 10-l is a block diagram showing the VP 100, the Centrex, and the connections between the two. For 
integration via SMDI, a 1200 baud serial data link provides information to the VP 100 regarding calls that 
have been fonvarded to the VP 100 ports. In addition, the VP 100 can Activate and deactivate Message 
Waiting Indication via this link. The data link connects to a customer-provided modem at the customer’s 
premise. 
l The follo\ving describes Centrex SMDI MWI and CPI operation. . 
Message Waiting SMDI tells the Centrex to provide a message waiting indicator in the form of a 
Indication stutter tone that can be activated by the VP 100 (for mail6oses with a COS 
containing Attribute 9). 
When the first new message is received in a mailbox, the VP 100 sends 
information to the CO to activate the MWI. If MWI is activated. whenever that 
station is used to originate a call, stutter dial tone is heard for approximately tvo 
seconds after which regular dial tone is heard. The stutter dial tone indicates that 
the mailbox associated with the station has new messages. Stutter dial tone is given 
each time an attempt to originate a call occurs until the mailbox is accessed. L\-hen 
the mailbox is accessed, the VP 100 sends information back to the CO to turn OFF 
the MWI. even if the messages are not listened to and erased.

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: 
l The cal!=d number. * 
l The typ-e of call forwarding.. 
l The calling number, if within the Centrex system. 
.- 
l The S3fDI ID number corresponding to the VP 100 port. 
Refer to the VP 100 Configuration for Centrex SMDI. in this chapter. 
The VP 100 then responds with the called party’s name. if it is recorded. or station 
number and starus (i.e. “nm~‘srario~r doeslr’f answer/is bz~$‘) and offers the caller 
choices such as leaving a private voice message, calling another station. or 
reaching assistance. 
If a call record is not received after a configured number of rings (defined in 
System Parameters), the VP 100 processes the call according to the mode of the 
port, i.e.. playing the company greeting for that port. 
Direct Call . 
If a Centrex station calls directly to the VP 100 port group. the VP 100 receives a 
call record that indicates the station is from within the Centrex. If the calling station 
has a mailbox in the USER Table. the caller is prompted: 
“To enter Four nwilbos. 
press pozod.” The 
person calling may then enter the mailbox. 
Refer to the SMDI Call Records section in this chapter. for more detailed information regarding how 
specific types of calls are handled.

10.2 CENTREX SMDI LIMITATIONS 
The \P 100 is restricted in how it interfaces with Centrex. The customer should be ad\-ised on these issues

DMS-100 and 
SL-100 
. 
Sequential Forwarding is illusrrated b>- the following: 
Station 23 11 is forwarded to 23 12 and 23 12 is in turn forwarded fb the VP 100. 
.x 71 .1 
. 
w mm a cm is forwarded from 23 I i iu 23 i 2, and then to the -VP I GO, the Ceriirex 
SMDI software tells the VP 100 that the call came from 23 
12. not the originally 
called station, 23 11. The VP 
100 treats the call as though the caller had intended to 
dial 23 12, and gives the wrong name or greeting. Sequential forwarding 
should be 
avoided! 
When Ce-t-e-, 
1111 h becomes biiijy. sending data to the VP 1M is slowed down. 
The VP 
100 can wait up to the amount of rings defined in System Parameter 99. 100, or 
117 for information sent from the CO. If the information is not sent, the VP 100 
answers with the company greeting, not the called party’s mailbox information. 
Refer to the Centrex Configuration section. 
If more than one VP 100 cabinet is required. additional SSIDI links and customer- 
supplied hardware are required for each cabinet. Stations must be forwarded to the 
appropriate cabinet. 
In the past, the DMS-100 and SL-100 did not send call records on direct external 
calls. For this reason, the VP 100 took longer to answer the port because it was 
waiting for the call record. This was improved with corrected software release 
BCS 25 for the DMS-I00 and SL-100. 
1 
./ 
When a caller accesses the VP 100. then abandons the call. the DMS-100 and 
the SL-100 wiii route the VP iO0 port. which is off hook. to a recorded 
announcement. The announcement nil1 be recorded as a message in the called 
party’s mailbox. This can cause the disk to fill up. 
. 
The DMS-lOO/SL-100 has a feature available called COD. Lvhich offers the VP 
100 a momentary disconnect. With System Parameter /7 set to YES. the VP 
100 uses that momentary disconnect to determine \vhen the called party 
abandons, and this problem is eliminated. 
. . 
Transfer for Uniform Call Distribution (UCD) has been espanded beyond the 
original call transfer capability of L-CD groups. It now allows UCD group 
members and non-UCD group members to transfer calls to other UCD groups. 
This expanded capability increases the customer’s call handling flexibility. For 
example, a three-way call chain can include a transferred call to a UCD group. 
This feature, included in the NTXlOlAX package available with BCS 27, on 
DMS-100, now permits transfer into the UCD that contains ports for a voice 
mail system. Formerly, this transfer could nor be done because it involved Call 
Forwarding Busy (CFB) and Call Forwarding Universal (Cl%). 
An enhancement in BCS 25. on DPIIS- 100 feature #AG 
15-k 1. enables this 
transfer for Call Forward Do Not Answer conditions. Fsacure #AG 1.54 1 can be 
patched to BCS 27.

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 Indication (MWI) features. 
.‘- 
l All Centrex lines that forward to the VP 100 must be programmed by tie CO to generate a call record 
over the SMDI link. 
l The lines must also be programmed to forward to the VP 100 multiline 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 Idkntification). 
- 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 ). 
b WARNING 4 
The following applies to 1AESS and some DMS 100 central offkes: 
Do not forward a station/extension to another station that subsequently forwards to the VP 100. 
The SMDI record shows only the last station that forwarded before going to the VP 100 hunt 
group. and the prompt gives that last station number, not the ori_ginal number dialed. 
However, for some DMS 100 central offices using BCS 30 software, or higher, and for SESS 
central offices, sequential forwarding is supported, and the cal! record wi!! reflect the original!y 
called extension. 
l l Phones that have mailboxes on the VP I_00 should be set up in the Centrex switch to have stutter dial 
tone, if MWI is desired. (For Message Waiting Indication). 
Toshiba VP Systems Release 6.1 December. 1992  
						

							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 
. . . 
camnp and caiieci maiibox numbers.

PORTS Table 
PREFIX 
Configure the PREFIX DIGITS Table to include all valid mailbox first digits. 
DIGITS Table Refer to the Co7~figumtio77 manual - PREFIX DIGITS Table. 
Multiple 
Prefixes With Release 6.1 and higher. the use of multiple prefixes in integrated Centrex 
installations can be supported.  The PORTS Table is used to configure ports in Centrex. 
Configure all ports that answer calls forwarded to the VP 100 for either AX, CX, 
or MS mode. Configure the PORTS Table as follows: 
In the station field for each port answering the Centrex lines, the station number 
must be the exact Message Desk Number plus the Message Desk Terminal 
Number assigned by the CO. It is a total of seven digits as described below. 
l Message Desk number = three digits with a range of 001-063. 
l Message Desk Terminal = four digits with a range of 0001-2047. . 
The \&sage Desk Terminal ID is supplied by the CO. The VP 100 treats this 
number as a VP 100 port’s station number. 
L@ If the Message Desk terminals are configured for ZFound start, they cannot 
be configured for outcall. 
Refer to the 
Cor7figu7-rrrio77 manual - PORTS Table, for further information on 
configuring the PORTS Table. 
The following is an example of a large Centrex installation where the number 
banks associated with the existing 294 prefix are exhausted, indicating the need for 
the use of a second prefix. The existing 294 prefix includes the number banks 294-

. The CPI portion of this application could be supported prior to Release 6.1, but 
Release 6.1 or higher is required for the KIWI part of the application. 
The following Release 6.1 changes are important in understanding how the 
additional prefix is to be supported: . . 
Prior to Release 6.1. when translation of digits \vas needed to support integrated 
systems. choice 1 (DID) was used to translate incoming call records (CPI). With 
Release 6.1 and higher. two ne\v choices are available: CPI INT (choice 4) and 
MWI INT (choice 5). 
Prior to Release 6.1_ the TRANSLATION Table was not used in the creation of 
the MWI command. The MWT record was obtained by looking at the first digit 
of the 
mailbox, searching the PREFIX DIGITS Table to obtain the digits 
associated with that first digit. and appending the extension number (from the 
USER Table) to those digits. In the above example. if the mailbox entry to the 
USER Table is 5700.5700. I. the Toshiba VP System identifies that the leading 
digits associated with first digit 5 are 294 and precedes the extension number
