INTRODUCTION CHAPTER 1 INTRODUCTION 1. GENERAL This manual describes the installation procedures, maintenance, etc. for connecting No. 7 CCIS (Common Channel Interoffice Signaling) lines to the PBX. The configuration of this manual is described in Section 2: “HOW TO FOLLOW THE MANUAL” of this chapter. 2. HOW TO FOLLOW THE MANUAL 2.1 Configuration of the No. 7 CCIS System Manual Table 1-1 Configuration of the No. 7 CCIS System Manual CHAPTER DESCRIPTION 1 INTRODUCTION Describes the No.
GENERAL INFORMATION FOR CCIS CHAPTER 2 GENERAL INFORMATION FOR CCIS 1. GENERAL This chapter describes the functional outline of CCIS, hardware required for CCIS, and service features which can be provided by CCIS. 2. DESCRIPTION OF CCIS The modular architecture and wide range of voice and data features available with the digital PBX’s have been developed with emphasis on continued enhancement within a single PBX.
GENERAL INFORMATION FOR CCIS Figure 2-2 Common Channel Interoffice Signaling COMMUNICATION LINK SIGNALING LINK REG CONTROL CONTROL Some advantages of the separate signaling link provided by CCIS are: (a) Network Transparency Because CCIS allows data relating to service features and station/trunk status to be exchanged between nodes at a high rate of speed (64 Kbps), service is provided to all users as though the CCIS network was a single PBX.
GENERAL INFORMATION FOR CCIS (d) Network Reliability Alternate Routing provides the CCIS network with maximum reliability. If the signaling link between two nodes should fail, signaling is sent over an alternate route, via another node, without loss of service. Directlyconnected redundant links can also be provided to assure the reliability of the network.

Note 2: When using Analog MODEM as the Control Link.
GENERAL INFORMATION FOR CCIS 4. NETWORK CONFIGURATION With application of No. 7 CCIS added to the PBX, a network of multiple functions as if it were a single PBX. Since calls can be freely transferred between one PBX and another, most of the existing station services can be applied to inter-PBX call connections.

GENERAL INFORMATION FOR CCIS 4.1 Types of Network CCIS networks can be divided into the following types, depending upon the numbering plan used: Main-Satellite Networks Main-Remote/Campus Networks Both networks provide uniformity of services throughout the CCIS network, and, because of numbering plan flexibility, station users are not conscious of the distance between nodes.
GENERAL INFORMATION FOR CCIS 4.2 Examples of Network Configuration 4.2.1 Main-Satellite Configuration Figure 2-6 shows an example of a Main/Satellite configuration for a nationwide corporate network. This type of network results in cost savings and increased efficiency by providing: • Leased lines versus toll lines. • Centralized Attendant Service. • One central location for call accounting.
GENERAL INFORMATION FOR CCIS 4.2.2 Campus Configuration Figure 2-7 shows an example of a Campus network. This type of network provides: • A uniform numbering plan: the first one or two digit(s) of the station number indicate(s) the location. In this numbering plan, four and/or five-digit station numbering can be used. • Network access to Common Carrier services. • Centralized Attendant service and network maintenance.
GENERAL INFORMATION FOR CCIS 4.2.3 Main-Remote Configuration Figure 2-8 shows an example of a Main/Remote configuration for a manufacturing/plant environment. This type of network provides the following advantages: • • • • • • • A central trunk location for trunking efficiency. Centralized management capability. Centralized attendant service. Centralized billing for inter-departmental accounting. Four digit inter-building and intra-city numbering. Feature transparency. Reduced calling.
GENERAL INFORMATION FOR CCIS 4.3 CCIS Network Modes The signaling channels of a CCIS network can be connected in one of two ways: Associated Mode or Quasi-Associated Mode. 4.3.1 Associated Mode An Associated Mode network is configured with a signaling channel (data link) between all nodes in the network. Signaling functions for all inter-node calls are carried over these dedicated signaling channels.
GENERAL INFORMATION FOR CCIS 4.3.2 Quasi-Associated Mode In Figure 2-10 below, nodes A and B, and A and C are connected in the Associated Mode. Nodes B and C are connected in the Quasi-Associated Mode. In this configuration, signaling data between nodes B and C is routed via node A, while the communication channels are established directly between nodes B and C. This type of network reduces the hardware necessary to establish the signaling links.
GENERAL INFORMATION FOR CCIS 5. DIGITAL NETWORK AND NETWORK SYNCHRONIZATION 5.1 Outline To set up a digital network, it is necessary to establish clock level synchronization among the offices composing the network. Among various kinds of synchronizing methods, the PBX is using Receiver synchronization as the standard method.
