CENTREX (Central Office Exchange) refers to virtual ISDN
PBXs. Although the public ISDN network is used as the
line network in this case, the usual PBX features are sup-
ported.
CENTREX features can only be accessed if you are a CEN-
TREX group member. If you are not a CENTREX group
member, the features described here do not apply.
Profiset 70isdn signals the arrival of CENTREX
voicemails. In order to use this feature, a programmable
key must be assigned the function "71=MWI" (
42). This programs the key with the directory number of
the mailbox to which you have access.
When a voicemail is received, the LED assigned to the
"MWI" feature key flashes.
Press the "MWI" key. The directory number of the
mailbox is dialed. The voicemails are then played back.
For incoming calls from other CENTREX users, Profiset
70isdn displays both the name and directory number of
the caller. The directory number is displayed first, fol-
lowed by the name.
A maximum of 24 characters can be displayed, additional
characters are not displayed if the name exceeds this
length.
The name is also entered into the call list (
Profiset 70isdn uses different call signals for external calls
and internal CENTREX calls. The following default call sig-
nals are used:
External calls
Tone (1 second)
Internal calls
Tone repeated twice (0.3 seconds each)
at 0.4-second intervals
