ISDN-NATIONAL AS DIALED

Sends the digits provided as an unknown number type.

Regardless of what type of number is received, the outgoing number is substituted with ISDN-National as the number plan and type. Ten digits are always sent to the network. Leading ones, if present, are stripped out and the area code (provisioned under DIAL PLAN/GLOBAL PARAMETERS) is added, if only seven digits are supplied. This action may be required in areas with ten-digit local dialing.

Examines the incoming number and if seven digits are received or if a ten-digit number is received with an area code that matches the area code provisioned in the global parameters, the number is forwarded to the network as a seven-digit number defined as ISDN-Subscriber number plan and type. If the incoming number is ten digits, but with a different area code, it is forwarded to the network as ISDN-National preferred.

Ignores the incoming numbering plan and type and substitutes the ISDN/Telephony numbering plan and National number type. Ten digits are sent to the network. Leading ones, if present, are stripped out and the area code set in global parameters is added if only seven digits are supplied. This action may be required in areas with ten-digit local dialing.

Sends the digits provided as National number type.

When SWITCH TYPE is set to 4ESS, many installations require the National form where possible; this may also be the preferred form in 10-digit calling areas.

DIAL PLAN (T1/PRI) > NETWORK TERM (PRI) > IFCE CONFIG (PRI) > 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.
