DIAL PLAN (E1/PRA) > USER TERM (PRA)
Write security: 3; Read security: 5

This menu allows the user to define option parameters for ports which emulate a PRA connection.

DIAL PLAN (E1/PRA) > USER TERM (PRA) > IFCE CONFIG (PRA)
Write security: 3; Read security: 5
Specifies the configuration parameters for the endpoint.
DIAL PLAN (E1/PRA) > USER TERM (PRA) > IFCE CONFIG (PRA) > SWITCH TYPE
Write security: 3; Read security: 5

Defines the type of PRA switch that the ATLAS 550 emulates. If connected to another ATLAS 550, both

need to be set to the same switch type. The following option is available:

• ETSI/DSS1

DIAL PLAN (E1/PRA) > USER TERM (PRA) > IFCE CONFIG (PRA) > FIRST DS0
Write security: 3; Read security: 5

Defines the first DS0 for this endpoint.The ATLAS 550 uses DS0s, starting with this selection, to send and

receive calls to and from the network. The outgoing calls which are allowed or restricted over these DS0s

are set by OUT#ACCEPT (see Dial Plan > Network Term > Out#Accept on page 254) and OUT#REJECT (see

Dial Plan > Network Term > Out#Rej on page 256).

DIAL PLAN (E1/PRA) > USER TERM (PRA) > IFCE CONFIG (PRA) > NUMBER OF DS0S
Write security: 3; Read security: 5

Specifies the number of DS0s ATLAS 550 uses for this endpoint.

DIAL PLAN (E1/PRA) > USER TERM (PRA) > IFCE CONFIG (PRA) > STRIP MSD
Write security: 3; Read security: 5

Strips a selected quantity (choose from NONE, 1, 2, and 3) of the most significant digits (MSD) of a dialed

number prior to being forwarded out of the port.

Example: A network port could be set to accept all calls beginning with 9 (9$), and then with STRIP MSD

set to 1, all digits would be sent toward the network except the leading 9.
DIAL PLAN (E1/PRA) > USER TERM (PRA) > IFCE CONFIG (PRA) > NETWORK SPECIFIC
FACILITY VOICE AND DATA
Write security: 3; Read security: 5

Enables the sending of appropriate information to the PSTN. Currently not supported for E1/PRA use.

STRIP MSD does not affect CALL ACCEPT criteria. All of the digits (including the MSDs that

are subsequently stripped) are used as accept criterion.
