T RANSFERRED
Write Security: 3; Read Security: 5
Defines the number of digits sent to the ATLAS 550 from the Network if
D IRECT I NWARD D IALING (see page 11-32) is enabled.
DID P REFIX Write Security: 3; Read Security: 5
Defines to the ATLAS 550 the prefix digits which are not received as a part
of the DID number. The ATLAS 550 uses the combination of prefix and DID
number to determine the user endpoint that should receive the incoming
call. This field only displays if
D IRECT I NWARD D IALING is enabled.
T RUNK N UMBER Write Security: 3; Read Security: 5
Determines which user endpoint should receive the incoming call when the
network connection does not provide DID digits. This field only displays if
D IRECT I NWARD D IALING (see page 11-32) is set to Disabled, and N ETWORK
T ERM (see page 11-33) is selected.
S TRIP MSD Write Security: 3; Read Security: 5
Strips a selected quantity (choose from
N ONE , 1 , 2 , and 3 ) of the Most Signif-
icant 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
S TRIP MSD set to 1 . Then, all digits would be sent toward the network
except the leading 9.
S OURCE ID Write Security: 3; Read Security: 5
Defines the source ID. Setting this menu item is optional.
S TRIP MSD does not affect C ALL A CCEPT criteria. All of the digits
(including the MSDs that are subsequently stripped) are used as
accept criterion.
