Descriptions
The cross-connect is intended for switching 16 digital E1 streams. The cross-connect control system allows you to assign arbitrary channel intervals (time slots), split the E1 stream into several substreams.
Scopes
- Integrated diagnostics features - loops, constants, harmonic signal generators, cycle counters, built-in BER tester;
- Conference grouping for voice channels with A-law PCM coding;
- Logical conjunction grouping for point-to-multipoint operation of asynchronous RS-232/485 (V.24, V.28) channels.
