DID D
IGITS
T
RANSFERRED
Write security: 3; Read security: 5
Defines the number of digits sent to ATLAS 550 from the network if
DID
is
used. This option only displays if
DID
is set to
E
NABLED
.
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
D
IRECT
I
NWARD
D
IALING
(DID) number. The ATLAS 550 uses the com-
bination of prefix and DID number to determine the user endpoint that
should receive the incoming call. This option only displays if
D
IRECT
I
NWARD
D
IALING
is set to
E
NABLED
. If
D
IRECT
I
NWARD
D
IALING
is
D

,
you must define the
T

N
UMBER
(see Trunk Number on page A-3).
T
RUNK
N
UMBER
Write security: 3; Read security: 5
Defines the number to use to determine which user endpoint should
receive the incoming call, when the Network connection does not provide
DID digits. This field only displays when
DID
is set to
D
ISABLED
.
E
XAMPLE
:
If a certain incoming DS0 (trunk) is meant to connect to an endpoint with
the accept number of 963-8615, the trunk number would be set to 963-8615.
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.
E
XAMPLE
:
A network port could be set to accept all calls beginning with 9 (9$), and
then with
S
TRIP
MSD
set to
1
, all digits would be sent toward the network
except the leading 9.
The trunk number must be specific (i.e., no wild cards).
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 criteria.
