equipment. In this case, ATLAS 550 is acting as the network.
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.
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.
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.
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).
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.
One HDLC resource is used by each PRI or each Packet Endpoint.
