Service Conditions
General:
Voice Mail Message Waiting on Line Key indication is supported for Centralised DSS/BLF keys if
PRG 20-13-41 [Class of Service Options (Supplementary Service)] – VM Message Indication on
DSS/BLF key (VMS Message Indication) is allowed.
If Voice Mail Message Waiting on Line Key indication is allowed and a VM Message Waiting
indication is provided (a new message is stored), pressing the Centralised DSS/BLF key
performs the following;
At system with Voice Mail installed, the user is logged into the owner mail box.
At remote systems, the station is called.
BLF Sending Service Conditions:
The maximum number of destination offices for sending BLF messages is eight per system.
Up to 120 Extension Numbers (entries into the table) can be assigned for sending BLF
messages. With each assigned Extension Number, up to eight destination offices can be
selected until a maximum of 240 total sending Extension Numbers are assigned.
A maximum of 240 total sending Extension Numbers (BLF messages) can be assigned. If 30
Extension Numbers (entries into the table) are assigned with each set for all eight groups
(systems), the 240 limit is reached and no more Extension Numbers can be entered.
The BLF messages are sent in a four-second cycle (at default), so some delay occurs to change
the indication in the destination office. In the network configured with two systems, it can take
about four to five seconds (at default) to change the BLF indication in the destination office.
This feature is provided with DSS/One-Touch Keys on multiline terminals and with an Attendant
Add-On Console.
When the button on the Attendant Add-On Console has a Mail Box button of a remote user
programmed and the button is pressed the call is placed to the station on the remote side.
BLF Receiving Service Conditions:
BLF information can be received for up to 120 remote extensions per system.
All multiline terminals in the system can assign Centralised DSS/BLF keys for the supported
remote extensions.
The LED indication of the DSS/BLF button on a multiline terminal is as follows:
Idle – No lamp indication
Busy – Steady red lamp
Do Not Disturb – Flashing red lamp
VM Message Waiting – Fast flashing red lamp
The LED indication of the DSS/BLF button on the Attendant Add-on Console is as follows:
Idle No lamp indication
Busy Steady red lamp
Do Not Disturb Flashing red lamp

The BLF Information expels when data cannot be sent because of link disconnect. Status
changes of BLF information while the system could not send data are not indicated on restoration.
The Voice Mail MSG Waiting has priority over any other state of the flashing line key or One-Touch
key.

This feature is supported with a Closed Numbering Plan only (not available with an Open
