The Echo range of E1 networking products gives organisations the opportunity to integrate voice and data traffic on E1 or fractional E1 circuits. Because multiple connections for different applications are no longer required, the Echo has a typical payback period of less than twelve months dependent on the traffic and circumstances. The Echo Mux provides Two Nx64Kbps data channels; an additional pair of N x 64Kbps data channels and/or a "drop & insert" interface may be added. Option modules for the Echo LANlink include voice compression and a high performance router. PABX voice channels are compressed freeing bandwidth for data applications, PCM digitised voice is compressed using the ADPCM algorithm with no noticeable degradation of quality. This effectively free bandwidth can be allocated to legacy data, video conferencing or the optional router. This router offers hardware compression to improve throughput and decrease latency.
