General Device Overview

The Siemens Memory Time Switch Large MTSL (PEB 2047) is an expansion of the MTSC (PEB 2045) regarding capacity and/or functionality. It is a monolithic CMOS switching device capable of connecting maximally 1024 PCM-input time-slots to 1024 output time-slots.

Features

● Non-blocking time/space switch for 2048-, 4096-, 8192- or 16 384-kbit/s PCM systems

● Different modes programmable for input and output separately

● Configurable for a 4096-kHz, 8192-kHz or 16 384-kHz device clock

● Switching of up to 1024 incoming PCM channels to up to 1024 outgoing PCM channels

● 16 input and 8 output PCM lines

● Tristate function for further expansion and tandem operation

● μP read-access to PCM data

● Programmable clock shift with half clock step resolution for input and output

● Individual line delay measurement and clock shift mechanism for 8 PCM inputs

● Built-in selftest

● 8-bit Motorola or Intel type μP interface

● Constant or minimal channel-delay programmable on a per time-slot basis

● In-operation adjustment of bit-sampling without bit errors

● Low power consumption

● Single 5 V power supply
