ADTRAN 1200305L1 system manual Voice Port

ATLAS 550 System Manual Section 4, User Interface Guide

VOICE PORT

Write security: 3; Read security: 5

Identifies the voice port address of the remote unit. Express units support ports 1 and 2. A remote ATLAS supports ports 1 through 255.

CONFLICT REPORT

Write security: 3; Read security: 5

Describes existing conflicts. Potential problems include DLCI unavailable or Voice port already in use.

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.
