Determining Point Code - NEC UNIVERGE SV9300 Networking Manual

Determining Point Code

Point Codes are used to distinguish an originating office and destination office in the No. 7 CCIS network.
A Point Code is assigned in each office in the No. 7 CCIS network. The following considerations are re-
quired when deciding the Point Code.
(1) The same Point Code cannot be assigned to more than one office.
(2) A single Point Code must not be assigned to each CCIS channel in the same system. When a system
has two or more CCH, the same Point Code (originating) has to be assigned to all CCH in a system.
(3) The maximum number of Point Codes is 256. (Only 256 offices can be connected in the same
network.)
