Write security: 3; Read security: 5
Defines to the ATLAS 550 whether Direct Inward Dialing (DID) is being
used by the network. If DID is E
NABLED
, then the following information
must be defined:
DID D
IGITS
T
RANSFERRED
Write security: 3; Read security: 5
Defines the number of digits sent to ATLAS 550from 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 tothe 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 option only displays if DID is set to E
NABLED
.IfDID is D
ISABLED
,
then you must define the trunk number.

Write security: 3; Read security: 5
When thenetwork connectiondoes notprovide DIDdigits, theATLAS 550 must
be given a number to use to determine which user endpointshould receive the
incoming call. T

UMBER
displays only when DID is set toD
ISABLED
.
E
XAMPLE
:
To connect an incoming DS0 (trunk) to an endpoint with the A
CCEPT
num-
ber of 963-8615, set the trunk number to 963-8615.
S
TRIP
MSD
Writesecurity:3; Read security: 5
Strips a selected quantity (choose from N
ONE
,1,2,and3) of theMost Signifi-
cant 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 to1, all digits would be sent toward the network
except the leading 9.
If Feature Group D signalling is used, DID only refers to DNIS
digits.
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 criterion.
