PREFIXwDIGiTS Table 18-l

18.1PREFIX DIGITS TABLE

The PREFIX DIGITS Table is used only with Adaptive Integration. If the Tbshiba VP System is

not equipped with this option, the configuration does not contain this table. ,

For Centrex installations that have SMDYSMSI and the optional Adaptive Integration feature, the PREFIX DIGITS Table should only be umfiiedif mailbox numbers are less&an seven digits

long.

In a Centrex instahation, the station numbers are typically three to four digits in length. However, the number dialed by outside calIers is seven digits The calI records sent over the SMDYSMSI link to the lbshiba VP System also contain this seven digit Centrex number. The Toshiba

VP System uses the PREFIX DIGITS Table to remove the leading prefm digits from the Centrex number. The remaining digits are the same as the ma&ox number of the call. (Station and mailbox number must match.)

When the Toshiba VP System sends a Message Waiting Indication command over the SMDVSMSI link to turn ON or OFF the MWI for a ma&ox, the Central Office (CO) expects the seven digit Centrex number corresponding to that station. In this case, the Toshiba VP System looks in the PREFIX DIGITS Table to get the leading prefix digits to add to the extension number before sending the Message Waiting Indication command.

For example, a Centrex installation may have stations 4XXX, !IXXX, and SXXX, with the corresponding seven digit Centrex numbers being 34%XXX., 345-5XxX, and 323-8xXx. The PREFIX DIGITS Table removes the leading prefa digits; the remaining digits are the station/mailbox number.

Some installations may have station numbers beginning with zero. The PTRSTDIGIT Table supports only 1 through 9 as valid frost digits. Therefore, the TRANSLATION Table must be used to convert OXXX to a valid first digit. For example, if Centrex sends 356-0123 to the Toshiba VP System, the PREFIX DIGITS Table strips off the 356, leaving 0123 as the station number. The TRANSLATION Table must be used to convert 0123 to 1123 or some other legal number.

Intecom PBXs send SMDI records with ASCII periods preceding the station number instead of office code digits or other numbers The PREFIX DIGlTS Table may contain one or more ASCII periods to be removed.

The following is an example of a PREFIX DIGITS Table:

All mailbox first digits must be entered in the table. List the FIRSTDIGIT Table to get a list of currently used mailbox first digits.
