Co Message Waiting Indication - NEC Univerge SV8100 Features And Specifications Manual

UNIVERGE SV8100
Description
This feature provides a Message Waiting indication when Voice Mail from the Central Office is used. The
CO provides this feature using Visual Message Waiting Indication (VMWI) standards. Visual Message
Waiting Indication alerts a user that a message is present in their voice mail box. When VMWI is provided,
the UNIVERGE SV8100 provides a flashing LED on a line key assigned with the trunk appearance.
The VMWI standard supported by the UNIVERGE SV8100 includes:
Type 1 Caller ID, FSK without power ringing using the MDMF protocol
Type 1 Caller ID, FSK without power ringing using the SDMF protocol
Conditions
When a new message is stored in the CO Voice Mail system, the LED flashes green (0.5 sec
ON, 0.5 sec OFF) on the Direct Trunk Appearance line key at stations assigned for this
feature.
When the Direct Trunk Appearance line key is used by other ports during green blink (flutter),
the line key becomes in use and LED is turned on red.
When the station is using a DTL-8LD telephone, <> flashes on the LCD of a Direct Trunk
appearance line key to indicate a new message is stored in the CO voice mail system.
A local Voice Mail system and this feature can be supported in the same system.
When power outage or some other reason causes the Central Office – Message Waiting
Indication (CO-MWI) to be out of synchronization with the system, an Attendant Position can
clear the CO-MWI per CO line.
The CO-MWI Callback Speed Dial number uses System Speed Dial Area.
This feature is supported at Multiline Terminals and DSS Consoles assigned with a direct line
key appearance of the CO/PBX line key supporting this feature and with proper Class of
Service assignment.
When additional digits (e.g., for password) are included in the CO Message Waiting
Indication System Speed Dial buffer, they must be separated by pauses to allow connection
to the CO Voice Mail system.
A Single Line Telephone or Wireless DECT (SIP) Handset cannot indicate the CO-MWI.
The Message Display Board does not support the CO-MWI.
