Determining Numbering Plan

The Uniform Numbering Plan is used for the numbering plan in the No. 7 CCIS network. The Uniform
Numbering Plan is provided by the Least-Cost Routing (LCR) feature, and there are two types of plans
described below.
• Station Number (Closed Numbering)
• Office Code and Station Number (Open Numbering)
When an outgoing call is placed through a CCIS link, an originating station number (Office Code and Sta-
tion Number) and a terminating Station Number are transmitted across the link to the destination office.
The originating station number consists of the office number assigned in CMA7 Y=06 and the station num-
ber assigned in CM10 Y=00 for the station time slot. The terminating station number consists of the dialed
number and the data assigned in CM8A (any LCR changes to the number dialed).
Next page shows an example of the Station Number (Closed Numbering) and Office Code and Station
Number (Open Numbering) respectively.
