VOICE COMPRESSION
Write security: 3; Read security: 5
Configures the compression algorithm used on the selected packet voice endpoint. The default
compression algorithm in the FSU and Express 52XX series is G.723.1. Valid codecs for the VCOM
Module include G.723.1 and NetCoder. Valid codecs for the ADPCM-32 Module include G.711,
G.726, and Transparent. The ADPCM-32 Module will only operate with another ATLAS containing
an ADPCM-32 Module. Both endpoints must agree on the selected compression algorithm.
The ADPCM-32 Resource Module will not interoperate with the FSU and Express series
products.
SILENCE SUPPRESSION
Write security: 3; Read security: 5
Reduces the total system bandwidth load by preventing ATLAS from sending frames containing a
special silence code during periods of silence. Both endpoints must agree to use silence suppression.
By default, silence suppression is DISABLED. To prohibit silence frames from transmitting and to
decrease the total system bandwidth, ENABLE this feature.
SIGNALING
Write security: 3; Read security: 5
Signaling method on the packet voice endpoint. Both endpoints must agree about the compression
algorithm choice. Options are E&M IMMEDIATE, E&M WINK, and LOOPSTART.
