1 BELL SYSTEM PRACTICES AT& TCo Standard SECTION Issue 6, December 1978 ALPHABETIC-NUMERIC INDEX STATION, KEY, PBX, AND PRIVATE SERVICE SYSTEMS 1. GENERAL 1.01 This section provides an alpha-numeric index of sections required for the installation and maintenance of customer product equipment and apparatus This section is reissued to update the alpha-numeric index This index combines the features of both alphabetic and numeric indexes. Sections can be located by referring first to the common nomenclature or ordering nomenclature, then referring to a major indention for the type of information such as,,, Reference, Service, etc., and then to the alphabetical or numerical listing. Here is a list of the symbols and the service manual to which they refer. SA-Station Service Manual SB-Station Service Manual II SC-Station Specialties Service Manual I SD-Station Specialties Service Manual II CA-Coin Service Manual I CB-Coin Service Manual II IA-Interconnect Service Manual I IB-Interconnect Service Manual II KA-Key Service Manual I KB-Key Service Manual II KC-Key Service Manual III PA-Dial PBX Service Manual 1.04 Many of the section numbers in this index are preceded by a two letter symbol such as SA. This symbol indicates that the section is contained in a service manual in addition to the standard BSP files.
