Our Echo Array is a Very High Density Voice Packetizer for building large scale PRI / E1 based TDM Voice Recording systems.
It includes embedded DSP arrays for D-channel decoding, voice processing and IP packet streaming.
The rugged design, low power consumption, redundant power supplies and TDM module hot-swap facility results in unmatched reliability.
D-channel signalling supports Call Setup, Connect, Clear, DDI number and CLI number decoding. It also supports all major ISDN variants, Q.SIG, DASS-2 and DPNSS.
It has highly secure encrypted IP streaming of the mixed upstream and downstream sides of a conversation.
The speech encoding/compression is 64kbit/s A-law (G.711), 36kbit/s proprietary encoding. The estimated MTBF is 600,000 hours.
