Features
•
CLIP/CLIR: Programmable to be enabled or disabled per system. The user is
allowed to program corresponding feature access codes into feature keys indi‐
cating programming status. Upon initiating outgoing ISDN trunk line call, the
calling extension's number will be sent out if CLIP is enabled.
•
COLP/COLR: Programmable to be enabled or disabled per system. The user is
allowed to program corresponding feature access codes into feature keys indi‐
cating programming status. Upon answering an incoming ISDN trunk line call,
the answering extension's number will be sent out if COLP is enabled.
•
DDI Service: Programmable to be enabled or disabled for each PRI port. When
an incoming ISDN trunk line call is answered, the DDI number will be received
by the system and checked against a DDI translation table. If one programming
entry is matched with the received DDI number, the system will ring the corre‐
sponding extension or hunt group number. If there is no match, the call will ring
the operator directly.
• ß
DDI Translation Table: This table is used to translate the received DDI number
into the desired destination number, which can be either an extension number or
a hunt group number. The length of the DDI number can be programmable, and
can be up to a 12‐digit in maximum. The total number of programming entries in
the table is 100 in maximum. If CLIP and COLP are enabled, if there is a pro‐
gramming entry matched with the calling extension or answering extension's
number, the corresponding designated DDI number will be sent out instead.
•
Auditing: The monitors the PRI port in order to keep track of its real time oper‐
ating status. The operating status may be one of the following two conditions:
failure to call setup or no connection. Through periodical monitoring, the latest
operating status can be kept, either from normal to failure, or vice versus. When
the PRI port is detected as "failure", the system blocks the interface and gives a
warning message upon access by the extension.
