DDI Enhancements - CPC-EX v2.1
CPC-EX version 2.1 contains an range of enhancements to the DDI operation of the DBS combined with E-ISDN
and DASSII. The new features are:
Separate DDI table for Night Service
Alternative DDI destinations in Day & Night modes for Busy or No Answer
DDI Ring Group membership increased from 8 to 32 members
DDI Hunt Group, DDI Ring Groups and extensions can be members
DDI calls to the operator extension are now subject to overflow ringing
DDI Night Service Table
The DBS now includes a second DDI table for use in Night Service. The table duplicates the options available for
Day Service and allows a separate DDI ringing scheme to be made operational out of hours.
Calls directed to the operator telephone will be re-routed to the Night Ring Telephone in Night Service.
When making calls the DDI sent to network will be the DDI from the table ( Day or Night ) in use at the time the
call is made.
Alternative DDI Destination - Busy / No Answer
CPC-EX v2 introduced and alternative extension option to which a DDI call can be routed if the primary
destination is busy. CPC-EX v2.1 enhances this option by allowing the alternative destination to be a group or
extension.
DDI Ring Group Membership
Membership of the DDI Ring Groups has been extended from the original 8 to 32 members.
DDI Hunt Group
A new Hunt Group type has been added to the software for the exclusive use of DDI calls. There are and
additional 16 DDI Hunt Groups allowing 16 members of each. Members can be extensions or DDI Ring Groups,
and the hunting mode is circular, with no answer or busy searching. No follow on group or alternative hunting
modes are supported. The existing Hunt Group operation is unchanged
For DDI Ring Groups to be included in a Hunt Group they will require a virtual extension number to be assigned to
reference them by. Extensions cannot be members of more than 1 DDI Hunt Group and cannot be included in a
more than 1 Ring Group assigned to a DDI Hunt Group, but can be individually in the same DDI Hunt Group as a
Ring Group in which it is also a member.
Group membership conditions for normal Hunt Groups are unchanged. (see following example )
In this example:
a) Cannot assign EXTN 300 to B, D and E
b) Cannot assign GROUP 310 to A, B, D and E
c) Cannot assign GROUP 320 to A, B, C and E
d) Cannot assign GROUP 330 to A, B, C and D
The original Hunt Group hunting takes precedence over the DDI Hunt
Groups. If there are calls to A and C and 300 becomes idle, the call
on A will have priority over the call to C.
