ATLAS 800 Series System Manual Dial Plan
E1/PRA: User Term - Ifce Config (PRA)
B Channel Selection Determines 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.
E1/PRA: User Term - Ifce Config (PRA)
Write security: 3; Read security: 5
T
his menu allows the user to define option parameters for ports which emulate a PRA connection.
Specifies the configuration parameters for the endpoint.
Switch Type Defines the type of PRA switch that the ATLAS 800 Series emulates. 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.
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. For 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.
Network Specific Facility
Voice and Data Enables the sending of appropriate information to the PSTN. Currently not
supported for E1/PRA use.
Called Digits TransferredDefines the number of digits to forward from the called number. When attached
to a PBX, the PBX may be provisioned to expect to receive fewer than all of the
called digits of the incoming call; however, this option would normally be set to
ALL. Choose from NONE, THREE, FOUR, SEVEN, or ALL.
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.
