CHAPTER 2 CUSTOMIZING DATA
1. GENERAL
This chapter explains the general information for customizing data and the various tables for customer
specifications such as numbering plan, station data and trunk data, etc., and sheets for designing the system
layout such as Bay Face Layout.
2. GENERAL INFORMATION ON CUSTOMIZING DATA
This section provides the information for customizing data in the Office Data Programming Manual.
2.1 Numbering Plan
This table specifies the service feature access codes, trunk access code, station numbers and other special access
codes. The service feature access codes and trunk access codes are given to each service feature and each trunk
routes, respectively, with a maximum three-digit code. The station numbers are specified by a maximum of four
digits.
For the numbering plan of the system the following conditions should be considered.
(1) The same first digit code cannot be assigned to the other features within the Numbering Plan Group
programmed. (This condition is not applicable to the system providing the Single Digit Timing Start
Access.)
(2) The feature access codes should be two or three digits because plural access codes for each feature are
required.
(3) There are four types of station numbering (1 digit – 4 digits), and any combination of these types is
available in one system.
(4) The same station number cannot be assigned, even if the tenant service is applied.
2.2 Station Data
In this table, the following data are required.
• Station Number
Station numbers (up to four digits), specified in the Numbering Plan Table, are assigned. For the D
term
