ADTRAN 1200305L1 system manual Dial Plan E1/PRA Network Term PRA Ifce Config PRA First DS0

ATLAS 550 System Manual Section 4, User Interface Guide

DIAL PLAN (E1/PRA) > NETWORK 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 (PSTN). 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) > NETWORK 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) > NETWORK 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.

STRIP MSD does not affect CALL ACCEPT criteria. All of the digits (including the MSDs that are subsequently stripped) are used as accept criterion.

DIAL PLAN (E1/PRA) > NETWORK 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.

DIAL PLAN (E1/PRA) > NETWORK TERM (PRA) > IFCE CONFIG (PRA) > CALLED DIGITS TRANSFERRED

Write security: 3; Read security: 5

Some PRI switches may be provisioned to send only a portion of the called number (like DID). This menu item allows the ATLAS 550 to know how many digits to expect (choose from NONE, THREE, FOUR, SEVEN, and ALL). The default is ALL and would almost always be correct. If less than ALL digits are sent, then the PREFIX is defined as follows:

PREFIX

Write security: 3; Read security: 5

Displays only if CALLED DIGITS TRANSFERRED is not set to ALL. Enter the prefix for the digits received.

Example: If the number of digits is four and the number called is 963-8615, the telco’s PRI switch sends only 8615 and the prefix is set to 963. This entire number is then used to determine which ATLAS 550 user port endpoint should receive the call.
