4,8,16,24 Channel Voice Compression Resource Modules (P/N 1200312Lx)
The Voice Compression Module (VCOM Module) combines with other ATLAS 550 components to
implement voice over frame relay (VoFR) capability. The Voice Compression Resource Modules support
4, 8, 16, or 24 simultaneous compressed calls using G.723.1 or Netcoder compression algorithms.
32 Channel ADPCM Resource Module (P/N 1200752L1)
The 32 Channel ADPCM Resource Module (ADPCM-32) combines with other ATLAS 550 components
to implement packet voice capability over frame relay. The 32 Channel ADPCM Resource Module
supports up to 32 simultaneously compressed or packetized calls using G.726, G.711, or Transparent
algorithms.
Nx 56/64 BONDing Resource Module (P/N 1200326L1)
The Nx 56/64 BONDing Resource Option Module supports multiple, independent BONDing sessions with
each session capable of using from 2 to 32 channels of 56 K or 64 K data. The Nx 56/64 BONDing
Resource Module combines with other ATLAS 550 components to provide a flexible disaster recovery
system.
