ATLAS 800 Series System Manual Dial Plan
E1/PRA: Network Term - Ifce Config (PRA)
B Channel Selection The following B CHANNEL SELECTION submenus determine how the ATLAS 800
Series switchboard uses B channels for call routing. The Circular method can be
used for call load balancing among the available B channels on this interface.
Busy Option The following BUSY OPTION submenus define the response propagated to the
CPE upon receipt of a
DISCONNECT USER-BUSY message from the network.
E1/PRA: Network Term - Ifce Config (PRA)
Write security: 3; Read security: 5
This menu allows the user to define option parameters for ports which terminate a PRA connection from
the network. Specifies the configuration parameters for the endpoint.
Switch Type Defines the type of PRA switch to which the port is connected. If connected to
another ATLAS 800 Series, both need to be set to the same switch type. The
following option is available:
ETSI/DSS1.
First DS0 Defines the first DS0 for this endpoint.The ATLAS 800 Series 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
OUT#ACCEPT (see Out#Accept on page 268) and OUT#REJECT (see
Submenus on page 274).
Number of DS0s Specifies the number of DS0s ATLAS 800 Series uses for this endpoint.
Strip MSD Strips a selected quantity (choose from NONE, 1, 2, and 3) of the most
significant 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
STRIP MSD set to 1, all digits would be sent toward the network
except the leading 9.
STRIP MSD does not affect CALL ACCEPT criteria. All of the digits (including the
MSDs that are subsequently stripped) are used as accept criterion.
Submenu Descriptions
Normal
Always start with the last channel configured (i.e., for a full PRI channel 23
would be used if available).
Circular
Contiguous channels from last to first.
Submenu Descriptions
Normal
Send a Progress message to the CPE and map busy tones.
Pass-Thru
Send a DISCONNECT USER-BUSY message to the User Term CPE device.
