At the proper time, an intercepted call is connected to the appropriateRAN trunk.Programming RAN trunksThe type of intercept and the RAN trunk parameters are defined in the TrunkData Block LD 14, Customer Data Block LD 15, and Route Data BlockLD 16 programs.The Trunk Data Block and Route Data Block programs specify the RANtrunk, the type of announcement machine, the number of repetitions ofannouncements before a forced disconnect (all calls) or an attendant interceptis initiated (CCSA/DID calls only), and the point at which the trunk may beconnected to the announcement.The Customer Data Block program defines the type of intercept and the trunkroute to which the intercept is to be connected.Refer to the Succession Communication Server for Enterprise 1000 X21Software Input/Output Guide Administration (553-3023-311) for instructionson service change programs.Electrical specificationsTable 7 gives the electrical characteristics of the universal trunk card.Table 7Universal trunk card – trunk interface electrical characteristics (Part 1 of 2)Characteristic CO/FX/WATStrunksDID or tietrunksRANtrunksPagingtrunksTerminal impedance 600 or 900 ohms (Note 1) 600/900 ohms(Note 1)600ohmsBalance impedance 600 or 900 ohms (Note 1),3COM, or 3CM2 (Note 2)N/A N/ASupervision type Ground orloop start(Note 3)Loop start(with ans sup)(Note 3)Continuous,level, or pulseN/ADC signaling loop length(max)1700-ohms loopwith near-endbattery of –42.75 V2450-ohms loopwith near-endbattery of –44 V600/900-ohmsloop600ohmsloopFar-end battery –42 to –52.5 V(Note 4)–42 to –52.5 V –42 to –52 V N/A
