DIAL PLAN (T1/PRI) > NETWORK TERM (PRI) > IFCE CONFIG (PRI) > OUTGOING NUMBER
CONVERSION
Write security: 3; Read security: 5
Converts outgoing (towards the network) numbers to the selected numbering plan and type option.
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.
AS DIALED Sends the digits provided as an unknown number type.
ISDN-NATIONAL
PREFERRED
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.
ISDN-SUBSCRIBER
PREFERRED
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.
ISDN-NATIONAL
DMS RESERVED
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.
ISDN-NATIONAL AS
DIALED
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.
STRIP MSD does not affect CALL ACCEPT criteria. All of the digits (including the MSDs that
are subsequently stripped) are used as accept criterion.
