DIAL PLAN (T1/PRI) > NETWORK TERM (RBS) > IFCE CONFIG (RBS) > DS0 SELECTION
Write security: 3; Read security: 5
Determines how the ATLAS 550 switchboard uses DS0s for call routing.
Example: The unit receives an incoming call on DS0 17. The switchboard looks for an interface who has matching
accept criteria to the number it received. A match is found on interface “Z” that has DS0 SELECTION set to ALIGNED.
This causes interface “Z” to only process the call if it has DS0 17 available. If all matching interfaces have DS0
SELECTION set to ALIGNED and none of those interfaces have DS0 17 available, then a busy or fast busy will be
returned to the calling party.
DIAL PLAN (T1/PRI) > USER TERM (PRI)
Write security: 3; Read security: 5
This menu allows the user to define option parameters for ports which emulate a PRI connection.
DIAL PLAN (T1/PRI) > USER TERM (PRI) > IFCE CONFIG (PRI)
Write security: 3; Read security: 5
Specifies the configuration parameters for the endpoint.
DIAL PLAN (T1/PRI) > USER TERM (PRI) > IFCE CONFIG (PRI) > SWITCH TYPE
Write security: 3; Read security: 5
Defines the type of PRI switch that the ATLAS 550 emulates. If connected to another ATLAS 550, both need to be
set to the same switch type. The following options are available:
DIAL PLAN (T1/PRI) > USER TERM (PRI) > IFCE CONFIG (PRI) > FIRST 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. The outgoing calls which are allowed or restricted over these DS0s
are set by OUT#ACCEPT (see Dial Plan > Network Term > Out#Accept on page 254) and OUT#REJECT (see Dial
Plan > Network Term > Out#Rej on page 256).
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. Use this for call load balancing
among the available DS0s on this interface.
ALIGNED Provides the ability to maintain alignment between T1s as if they were
in dedicated map mode. This scenario requires DS0 SELECTION set to
ALIGNED on both interfaces (usually on User Term and on Net Term). An
interface that has DS0 SELECTION set to ALIGNED will only process a call
from the switchboard on the same DS0 that the incoming call was
received.
