Network Structure Considerations
NEAX2000 IVS2 CCIS System Manual    
ND-70918 (E), Issue 1.0   Page 35
NETWORK STRUCTURE CONSIDERATIONS
Determining System Configuration
The configuration of the network and the number of lines (channels) should be determined, and
is dependent on the traffic between each office (PBX). For example, when the traffic between
Office A and Office C is high (as shown in the network of the following figure), Office A and Office
C should be connected by No. 7 CCIS directly.
Figure 1-13  Network Structuring
Determining Number of No. 7 CCIS Routes
When the system is a Main Office or a Tandem Office, two or more routes to other offices are
required.
 The maximum number of No. 7 CCIS routes is 8 per system.
Determining Type of Transmission Lines
The type of transmission lines available with the PBX are:
 Digital Interface (24-DTI/30-DTI)
 Analog Interface (LDT/ODT)
The Analog Interface is not suitable for a high-traffic network because the transmission speed of
the control signal is limited to a maximum of 9.6 Kbits per second (bps). A Digital Interface can
transmit control signals at up to 56 Kbps.

CHAPTER 1 GENERAL INFORMATION
Network Structure Considerations
Determining Which PBX Should Be Main Office
When using No. 7 CCIS, the following features require establishing a clear relationship between
the Main and Satellite offices:
 Centralized Attendant Service (CAS)
– Attendant Camp-On with Tone Indication-CCIS
– Busy Verification-CCIS
– Centralized Day/Night Mode Change-CCIS
For Centralized Day/Night Mode Change Service, the Main Office must be the IMX. This 
feature can be set only from the Main Office IMX: The IVS’s Attendant Console cannot set 
this feature. The IVS provides the feature when instructed by the Main Office.
 Centralized Billing-CCIS
 Centralized Fault Message
Main office: IMX only
The IVS can pass information, but cannot generate alarm information and send over CCIS.
 Centralized MAT-CCIS
Main office: IMX only
Number Portability-CCIS
Main office: IMX only 
						

							CHAPTER 1 GENERAL INFORMATION
Network Structure Considerations
NEAX2000 IVS2 CCIS System Manual    
ND-70918 (E), Issue 1.0   Page 37
For Centralized Fault Message, the PBX cannot generate its own fault message. It can only relay
a fault message from one office to another office.
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 required 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.)
For example: Point Code Assignment
When Office A and Office C are IMX and Office BOFFICE B
is a PBX, a fault message from Office A can be
