D IGIT S UPPRESSION Write security 3; Read security: 5
When enabled, no digits will be sent toward the network/PBX after going
off-hook on an outgoing call.
D IRECT I NWARD
D IALING
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 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 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 . If DID is D ISABLED ,
then you must define the trunk number.
T RUNK N UMBER Write security: 3; Read security: 5
When the network connection does not provide DID digits, the ATLAS 550
must be given a number to use to determine which user endpoint should
receive the incoming call.
T RUNK N UMBER displays only when DID is set to
D ISABLED .
Example:
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.
If Feature Group D is used, DID only refers to DNIS digits.
The trunk number must be specific (i.e., no “wild cards”).
