S WITCH T YPE Write security: 3; Read security: 5
Defines the type of PRI switch that the ATLAS 550 is going to emulate. If con-
nected to another ATLAS 550, both need to be set to the same switch type.
F IRST DS0 Write security: 3; Read security: 5
Defines to the ATLAS 550 the first DS0 for this endpoint. The ATLAS 550
uses DS0s, starting with this selection, to send and receive calls to and from
the network (PSTN). The outgoing calls which are allowed or restricted
over these DS0s are set by the
O UTGOING C ALL A CCEPT and R EJECT N UM -
BERS (discussed in the ATLAS 550 User Manual).
N UMBER OF DS0 S Write security: 3; Read security: 5
Specifies the number of DS0s ATLAS 550 uses for this endpoint.
S TRIP MSD Write security: 3; Read security: 5
Strips a selected quantity (choose from
N ONE , 1 , 2 , and 3 ) of the Most Signifi-
cant 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
then with
S TRIP MSD set to 1 , all digits would be sent toward the network
except the leading 9.
N ETWORK S PECIFIC
F ACILITY
Write: 3; Read: 5
Enables the sending of appropriate information to the PSTN. The default
for this option is
N ORMAL , and in this case no Network Specific Facility
information element is sent. Unless one of the services listed below is sub-
scribed to, the selection should remain set to
N ORMAL .
The list below indicates services that may be subscribed to from the PSTN.
These services require that specific information (such as a Network Specific
Facility information element) be sent to the network during call setup.
• Lucent 5E • Northern DMS 100
• Nation ISDN • AT&T 4ESS
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.
