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" (page 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 (page 51).

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)

 

 

 

 

Pause (4 seconds)

etc.
