equipment. In this case, ATLAS 550 is acting as the network.

In applications where two ATLAS 550 units are used in a point-to-point configuration, a port in the ATLAS 550 at one end would act as the network (user termination), while the ATLAS 550 at the opposite end would be terminating a network connection (network termination).

DIAL PLAN > USER TERM > SLOT/SVC

Write security: 3; Read security: 5

Selects the ATLAS 550 slot or service that terminates a user connection.

DIAL PLAN > USER TERM > PORT/PEP

Write security: 3; Read security: 5

Selects the ATLAS 550 port or packet endpoint that terminates a user connection.

There may be more than one “endpoint” associated with a particular port. If a T1 is connected to the PSTN, some DS0s may be used for long distance, while others are used for local calls. These would constitute two “endpoints” (trunks) over a single physical port.

DIAL PLAN > USER TERM > SIG

Write security: 3; Read security: 5

Defines the type of signaling being used for this connection (endpoint). Select RBS for a T1 using robbed bit signaling or PRI for a Primary Rate ISDN interface. This selection is only necessary if a T1/PRI is selected as the SLOT/PORT type.

One HDLC resource is used by each PRI or each Packet Endpoint.

DIAL PLAN > USER TERM > IN#ACCEPT

Write security: 3; Read security: 5

Defines the parameters for the incoming calls that ATLAS 550 accepts from the network.
