SV9100 Networking Manual
BLF information can be received for up to 120 remote extensions per system.
All multiline terminals in the system can assign Centralized 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

Busy

Do Not Disturb

VM Message Waiting

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 not supported between UNIVERGE SV9100 and NEAX PBXs.
This feature is supported with a Closed Numbering Plan only (not available with
an Open Numbering plan).
The same extension line from a remote site can be assigned to multiple DSS/
One Touch keys.
The BLF information is expelled when data cannot be sent if the K-CCIS link is
down. The UNIVERGE SV9100 does not send BLF information again when the
K-CCIS link is restored.
BLF messages can be forwarded up to eight times in the network. When
designing the K-CCIS network, this should be a consideration.
When a Centralized DSS/BLF key is first programmed on a Feature Access or
One Touch key, the BLF status does not change (update) until new BLF
information is received from the remote system.
