DIAL PLAN (FXO) > NETWORK TERM > IFCE CONFIG > NUMBER OF PORTS
Write security: 3; Read security: 5

Specifies the number of ports ATLAS 550 uses for this endpoint.

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

Defines to the ATLAS 550 the type of signaling to be used across this trunk. The signaling selected needs

to match the signaling being provided by the network (PSTN). The following choices are available:

DIAL PLAN (FXO) > NETWORK TERM > IFCE CONFIG > DIGIT SUPPRESSION
Write security: 3; Read security: 5

When ENABLED, no digits will be sent toward the network/PBX after going off-hook on an outgoing call.

DIAL PLAN (FXO) > NETWORK TERM > IFCE CONFIG > DIRECT INWARD DIALING
Write security: 3; Read security: 5

Defines to the ATLAS 550 whether Direct Inward Dialing (DID) is being used by the network. If DID is

ENABLED, then the following information must be defined:

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

Defines the number of digits sent to ATLAS 550 from the network if DID is used. This option only displays

if DID is set to ENABLED.

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

(Visible only if DIRECT INWARD DIALING is set to Enabled.) Defines the prefix digits which are not received

as a part of the DID number. The ATLAS 550 uses the combination of prefix and DID number to determine

the user endpoint that should receive the incoming call. If DIRECT INWARD DIALING is DISABLED, a TRUNK

NUMBER must be defined.

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

(Visible only if DIRECT INWARD DIALING is set to Disabled.) When the network connection does not provide

DID digits, the ATLAS 550 must be given a number to use to determine which user endpoint should

receive the incoming call.

Loop Start Ground Start

The ATLAS 550 converts signaling types between two endpoints (network or user terms).

The TRUNK NUMBER must be specific (i.e., no “wild cards”).
