1 BELLSYSTEM PRACTICES SECTION AT&TCo Standard Issue 6, February 1979 ALPHABETIC-NUMERIC INDEX STATION, KEY, PBX, AND PRIVATE SERVICE SYSTEMS 1. GENERAL Here is a list of the symbols and the service 1.01 This section provides an alpha-numeric index manual to which they refer. of sections required for the installation and maintenance of customer product equipment and SA--Station Service Manual I apparatus. SB--Station Service Manual II SC--Station Specialties Service Manual I 1.02 This section is reissued to update the SD--Station Specialties Service Manual II alpha-numeric index. CA--Coin Service Manual I CB--Coin Service Manual II 1.03 This index combines the features of both IA--Interconnect Service Manual I alphabetic and numeric indexes. Sections IB--Interconnect Service Manual II can be located by referring first to the common KA--Key Service Manual I nomenclature or ordering nomenclature, then referring KB--Key Service Manual II to a major indention for the type of information KC--Key Service Manual III such as,, Maintenance, Reference, Service, etc., and then to the alphabetical PA--Dial PBX Service Manual or numerical listing Many of the section numbers in this index are preceded by a two letter symbol such as SA.
