VI. Server Cards
1. ADPCM Voice Compression Server
The 887160 ADPCM (Adaptive Differential Pulse Code Modulation) server card is designed to compress digital and analog voice traffic for transmission over wide area network links. The level of compression for an individual channel is software configurable at 24Kbps, 32Kbps or 40Kbps. This card requires a matching card at the other end to decompress the voice channels to normal 64 Kbps operation. A single ADPCM card is capable of compressing
64 channels of voice simultaneously. Since the ADPCM card is a server card, these 64 channels can be originated from a variety of interfaces, including FXS, FXO, E&M, SRU, BRI, and T1/E1. In a 3.x platform, up to two ADPCM server cards can be supported per IMACS system for a total of 128 compressed voice channels. In a 5.x platform, 3 ADPCM cards could be used to carry a total of 192 voice channels.
