CHAPTER 1 GENERAL INFORMATION Network Structure Considerations NEAX2000 IVS2 CCIS System Manual ND-70918 (E), Issue 1.0 Page 39 Determining CCH Link to Send Messages Each system MP must be programmed with the proper information indicating to which CCH (in its own system) every other office in the network is connected. This is required for providing inter- office services such as Attendant Camp-On, Call Back, and Busy Verification when using CCIS. In each system, CMA8 is used to inform the local MP which system is connected through which CCH. This is extremely important, not only for where two switches are connected to each other, but also for networks in which tandem signaling is used.

NEAX2000 IVS2 CCIS System ManualPage 40 ND-70918 (E), Issue 1.0 CHAPTER 1 GENERAL INFORMATION Network Structure Considerations Data Assignment of Office C Data Assignment of Office D Example 2: In this example, there are two connection patterns from Office A to Office D, A-B-D and A-C-B- D. Office A’s first choice route in the LCR (Least-Cost Routing) Route Pattern Table would be CCH0 (whatever route the voice channel is assigned to). The second choice would be to the voice route associated with CCH1, which is connected to Office C. At Office C the programming is set up to call and signal Office B, which then routes the call to Office D.

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 Station 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 YY=06 and the station number assigned in CM10 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). Figure 1-14 and Figure 1-15 show an example of the Station Number (Closed Numbering) and Office Code and Station Number (Open Numbering) respectively.

CHAPTER 1 GENERAL INFORMATION Network Structure Considerations NEAX2000 IVS2 CCIS System Manual ND-70918 (E), Issue 1.0 Page 43 Limitations on developing the Uniform Numbering Plan are as follows: (1) Station Number (Closed Numbering) The dialing number must be formed as follows: When providing 3-digit or 4-digit station numbering within the No. 7 CCIS network, the data assignment of the Originating Office Number (CMA7 YY=06) is not necessary because the Originating Office Number is included in the originating station number. LCR Group 3 (CM20>A129) must be used for assigning an LCR access code. (2) Office Code and Station Number (Open Numbering) The dialing number must be formed as follows. XXXXXXXX Station Number (Max. 8 digits) Office Location Number (Max. 2 digits) a 1 a2 b1 b2 b3 c1 c2 c3 c4 c5 c6 c7 c8 Station Number (c) Office Code (b) Access Code (a) (a) ≤2 digits (a) + (b) ≤4 digits (c) ≤8 digits a1≠c1
NEAX2000 IVS2 CCIS System ManualPage 44 ND-70918 (E), Issue 1.0 CHAPTER 1 GENERAL INFORMATION Network Structure Considerations LCR Groups 0-3 (CM20>A126-A129) can be used for assigning an LCR access code. When providing a pseudo dial tone to alter the dialing access code, LCR Groups 0-2 (CM20>A126-A128) must be used.
