Outgoing Number
Conversion Converts outgoing (towards the network) numbers to the selected numbering
plan and type option.
Strip MSD 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. For 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.
Submenu Description
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.
