5 / 63 page  Semiconductor Group 5 01.96 PEB 2096 1Overview A Line Card or a PBX consists of a line card controller, multiple layer-1 transceivers for t/r (a/b), S/T, UP and U2B1Q interfaces, signaling controllers, a microprocessor, memory, power supply, transformers, etc. The new Siemens generation of highly integrated ISDN circuits enables design Engineers to decrease board size and thus PBX size and its production costs. Figure 1 shows an example of a PBX for up to 16 ISDN and 16 analog subscribers with 4 trunk lines realized with a few highly integrated chips of the new Siemens family of PBX and Line Cards ICs: ELIC, SICOFI-4, OCTAT-P, QUAT-S and IDEC. ELIC, Enhanced Line Card Controller, PEB 20550, comprises the following functional blocks on a single chip: • Extended PCM Interface Controller (EPIC-1), which can switch up to 32 digital (ISDN) or 64 voice (analog) subscribers, • Two HDLC interface controllers (SACCO-A and SACCO-B), • One D-channel arbiter to multiplex one HDLC controller (SACCO-A) to multiple subscribers. The ELIC is a CMOS device offered in a P-MQFP-64 package. OCTAT-P The Octal Transceiver for UPN interfaces, PEB 2096, implements the two-wire UPN interface used to link voice/data digital terminals to PBX subscriber lines. The OCTAT-P is an optimized device for LT applications and can handle up to eight UPN interfaces simultaneously. It handles the UPN interfaces in accordance with the UP0 interface specification except for the reduced loop length. The OCTAT-P is a CMOS device offered in a P-MQFP-44 package. QUAT-S The Quadruple Transceiver for S/T Interfaces, PEB 2084, implements 4 four-wire S/T interfaces to link voice/data digital terminals to PBX subscriber lines or PBX trunk lines to the public ISDN. It can handle up to four S/T interfaces simultaneously in accordance with CCITT I.430, ETSI 300.012, and ANSI T1.605 standards. The QUAT-S is a CMOS device offered in a P-MQFP-44 package. IDEC The ISDN D-Channel Exchange Controller, PEB 2075, is an HDLC controller which handles four HDLC communication channels. Each channel is fully independent and programmable by its own register set. The IDEC is a CMOS device offered in a P-LCC-44 and P-DIP-28 package. |
