DIAL PLAN (PKT VOICE) > NETWORK TERM > IFCE CONFIG > 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.72 6,

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.

DIAL PLAN (PKT VOICE) > NETWORK TERM > IFCE CONFIG > 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.

DIAL PLAN (PKT VOICE) > NETWORK TERM > IFCE CONFIG > SIGNALING METHOD
Write security: 3; Read security: 5

Selects the type of signaling that the remote port is configured to expect. Available options include E&M

IMMEDIATE, E&M WINK, and LOOP START.
DIAL PLAN (PKT VOICE) > NETWORK TERM > IFCE CONFIG > DIRECT INWARD DIALING
Write security: 3; Read security: 5

Defines whether Direct Inward Dialing (DID) is used by the remote equipment. If DID is enabled, then the

following options must be configured:

DIAL PLAN (PKT VOICE) > NETWORK TERM > IFCE CONFIG > DID DIGITS TRANSFERRED
Write security: 3; Read security: 5

Defines the number of digits sent to ATLAS from the network if DIRECT INWARD DIALING is ENABLED.

DIAL PLAN (PKT VOICE) > NETWORK TERM > IFCE CONFIG > DID PREFIX
Write security: 3; Read security: 5

Defines to ATLAS the prefix digits which are not received as a part of the DID number. ATLAS uses the

combination of prefix and DID number to determine the user endpoint that should receive the incoming

call.

DIAL PLAN (PKT VOICE) > NETWORK TERM > IFCE CONFIG > TRUNK NUMBER
Write security: 3; Read security: 5

Determines which user endpoint should receive the incoming call when the network connection does not

The ADPCM-32 Resource Module will not interoperate with the FSU and Express series

products.
