Overview

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.

Features

? Eight full duplex 2B+D UPN interface transceivers, each equipped with the following functions:

– Conversion from/to binary to/from pseudo-ternary code

– Receive timing recovery

– Activation/deactivation procedures, triggered by primitives received over the IOM interface or by INFO received from the line (e.g. detection of INFO 1)

– Execution of test loops

– Analog line transceiver for up to 16 dB line attenuation

– UPN interface functions compatible to PEB 2095, IBC, and PEB 20950, ISAC-P (except for looplength)

– UPN interface fully compatible to PSB 2196, ISAC-P TE, and PSB 2197, SmartLink-P.

? IOM-2 interface

? Support for JTAG boundary scan test

? 1μ CMOS technology with low power consumption

? P-MQFP-44 package
