Quad T1/PRI Module (User Termination/PRI)
When you are working in the User Termination section of the Dial Plan menu, the
Slot is defined as a T1/PRI module, and Sig is set to PRI, the following configura-
tion options are available:
Switch Type
Write security: 3; Read security: 5
Defines the type of PRI switch that ATLAS is going to emulate. If connected to
another ATLAS, both need to be set to the same type.
• Lucent 5E
• AT&T 4ESS
First DS0
Number of DS0s
Write Security: 3 Read Security: 5
These two items permit fractional PRI to be defined. These menu items
define the first active DS0 and the number of DS0s used for calls on this PRI.
DS0 24 is assumed to be used by the PRI for the “D” channel.
Strip MSD
Write Security: 3 Read Security: 5
This option allows a selected quantity of the Most Significant Digits (MSD) of
a dialed number for ATLAS to be stripped 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
Strip MSD
set to 1, all digits would be sent toward the Network
except the leading 9.
The Strip MSD parameter does not affect the Call Accept criteria. All of
the digits (including the MSDs that are subsequently stripped) are used as
accept criteria.
Network Specific Facility Voice
Write Security: 3 Read Security: 5
This option defines the specific facility IEs be sent to the Network. This
would be used if the customer has subscribed to special facilities such as
AT&T Megacom service. The facility request sent can be different for voice
calls versus data calls. A setting of
Normal indicates no special facilities have
been subscribed.
Network Specific Facility Data
Write Security: 3 Read Security: 5
This option defines the specific facility IEs be sent to the Network. This
would be used if the customer has subscribed to special facilities such as
AT&T Megacom service. The facility request sent can be different for voice
calls versus data calls. A setting of
Normal indicates no special facilities have
been subscribed.
