Digital Circuit Multiplication Equipment DTX-360 OVERVIEW
Using DSI (Digital Speech Interpolation), LRE (ADPCM/LDCELP), VBR (Variable Bits Rate and Fax Demodulation/Modulation techniques, the DTX-360 enables a maximum effective compression of transmisssion facilities in digital operating environments, together with a high level of signal quality and system reliability. Each DTX-360 terminal accepts upto 360 trunk channels, carrying 64 Kbps
signal (12 E1 Trunks) of speech voice-band data (non-fax), fax and inter-exchange
signaling types. After effective compression these signals are transmitted to the
receiving end DTX360(s) over single E1 bit-stream Bearer. The receiving end DTX 360 (s)
decompresses and restores the original signals. |
