» State
Read Security: 5
Indicates the condition of the individual VoFR device (see Table 3-3).
» Algorithm
Read Security: 5
Denotes the voice compression algorithm being used by the VoFR device.
Any VoFR device can use any available compression algorithm. When
ATLAS chooses a VoFR device for a particular call, the voice compression
algorithm is set to match the dial plan endpoint configuration (see Table 3-
4). Refer to Chapter 5, Dedicated Map and Dial Plan Menus, in the ATLAS
Frame Relay User Manual for more information.
» Silence
Read Security: 5
Reduces total system bandwidth load.
Voice endpoints continue to originate frame relay traffic during periods of
relative silence. The VCOM Module expects to receive such silence frames;
therefore, silence compression is
Disabled by default. Some voice end-

Some voice compression standards are proprietary and may be used
only under specific licensing arrangements. ATLAS provides
complete management of these licensed resources; therefore, users are
not required to take additional steps to ensure conformance with
licensing provisions. For example, ATLAS manages its resources so
users never exceed the maximum licensed number of simultaneous
connections. Refer to Chapter 3, Installation, in the ATLAS Frame
Relay User Manual for details.
