Disa (Direct Inward System Access); Distinctive Ringing; Flexible Dial Plan; Flexible Ringing Assignment - Panasonic DBS 576HD Technical Manual

DISA (DIRECT INWARD SYSTEM ACCESS)

Description:
Any number of CO lines can be assigned to DISA lines which after being accessed, will enable
the incoming caller to dial any extension within the system. Or, if the proper security code is
entered, the caller will be able to access outside lines. Remote programming can also be done
over these lines after entering a password.
Benefits:
• Allows internal personnel to access the system without tying up the attendant or other
lines coming into the system.
• Enables people away from the office to access T1, FX (Foreign Exchange), Network,
etc., to make long-distance calls using less expensive means.
Applications:
• Field sales people, repeat customers, etc.

DISTINCTIVE RINGING

Description:
Individual CO lines and stations can have their own unique ring pattern and frequency for
incoming calls, to distinguish them from other lines or phones. If no distinctive ringing is
assigned, the CO's ring pattern will be heard.
Benefits:
• Allows users to recognize the ring of their own individual telephones, or distinguish
between different types of incoming calls.
•
• Companies with separate departments or large, open bullpen areas

FLEXIBLE DIAL PLAN

Description:
The DBS 576HD's dial plan is flexible. This means that the system comes with a default set of
feature codes, which can be changed. (For example, the default Call Forward-All Calls feature
code is 721. But you can change it to 7, or 2#, or ***, or anything else between 1 and 4 digits
long.)
It also means that you can have two different sets of feature codes for each system, dividing
extensions into two different groups (for example, SLT phones can have a different set of feature
codes than digital extensions). Each extension can be assigned Dial Plan A or Dial Plan B.
Benefits:
• Analog and digital phones can each have a unique set of feature codes.
• The DBS 576HD can be designed to match the current phone system's feature
numbering plan, therefore minimizing training.

FLEXIBLE RINGING ASSIGNMENT

Description:
Ringing assignment is completely flexible so any CO line can be assigned to ring at any station
with a line-appearance key. This ringing assignment can differ in Day 1, Day 2, and Night modes
depending on user requirements.
