The Siemens Memory Time Switch Extended Large MTSXL (PEB 2447) is a capacity
expansion of the MTSL (PEB 2047). It is a monolithic CMOS switching device capable
of connecting maximally 2048 PCM input time slots to 2048 output time slots. In order to
manage the problem of different line delays, six additional FS inputs can be used as
frame measurement inputs and 16 different input offsets of PCM frames are allowed.
Thus a frame wander can be compensated by adjusting the input offset during operation.
A special circuitry guarantees that no bit error will occur, when reprogramming the input
offsets.
The MTSXL on chip connection memory and data memory are accessed via the 8-bit
standard P interface (Intel demultiplexed type).
A built-in selftest mechanism – also activated by the
operation in the system.
The PEB 2447 is fabricated using the advanced CMOS technology from Siemens and is
mounted in a P-MQFP-100-2 package. Inputs and outputs are TTL compatible.
