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.

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.

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:

•	Lucent 5E	•	National ISDN
•	Northern DMS 100	•	AT&T 4ESS

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).
