Class Of Service (Cos) Restriction; Conferencing - Panasonic DBS 576HD Technical Manual

LCD indication of caller information. Users can see caller information (both name and
number) displayed while the incoming call is ringing their extension. This includes ISDN
digital messaging through the D-channel, also known as ANI (Automatic Number
Identification).
Log of caller information. The Call Log keeps a record of the last 10 CID calls received at
an individual phone, and allows the user to view the Log and select from it to place a call.
Up to 20 phones per cabinet can have the Call Log feature.
SMDR recording. CID information can be sent to the RS232C serial port so that it can be
printed to a serial printer or call accounting system.
CID notice to CTI. CID information sent by the CO can be output to TAPI and other CTI
devices.
Benefits:
• Allows users to handle calls more efficiently by knowing who is calling before they
answer.
• Enables users to return calls that ring unanswered at their phones.

CLASS OF SERVICE (COS) RESTRICTION

Description:
Specific feature restrictions can be placed on extensions or on trunks. There are up to 16
definable classes of service for extensions, and 16 more for trunks. If no COS is assigned, most
features are allowed.
Benefits:
• Allows users to have telephones customized to their needs.
Applications:
• Users with Single Line Telephones (SLTs) or those who need to limit access to
various features on selected telephones

CONFERENCING

Description:
Any digital phone user can initiate a conference that includes from 3 to 7 other participants, who
can be either intercom phone users or outside parties. (NOTE: Optional equipment must be
installed in the DBS 576HDcabinet to support more than 4 parties in a conference.) During a 3-
party conference, a digital intercom phone participant can establish a private conversation with
one of the other parties, then rejoin both to the conference. Since the system is digital, there is
no internal dB loss during a conference - but you can still program additional dB gain/loss
settings for conference calls.
Benefits:
• Saves time and money associated with conferencing geographically-separated
employees, customers, etc.
• Users can establish their own conference calls without auxiliary equipment.
