Chapter 11. Dial Plan61200305L1-1 ATLAS 550 User Manual 11-3N ETWORK TERM This menu allows the user to define option parameters for ports which ter-minate a connection from the Network (PSTN).S LOT /SVC Write security: 3; Read security: 5Selects the ATLAS 550 slot that terminates a Network connection.PORT /PEP Write security: 3; Read security: 5Selects the ATLAS 550 port that terminates a Network connection.S IG Write security: 3; Read security: 5Defines the type of signaling being used for this connection (endpoint).Select RBS for a T1 using Robbed Bit Signaling or PRI for a Primary RateISDN interface. This selection is only necessary if a T1/PRI is selected as theS LOT /PORT type.O UT #ACCEPT Write security: 3; Read security: 5Defines the parameters for the outgoing calls that ATLAS 550 sends to theNetwork.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 actas the Network (User termination), while the ATLAS 550 at theopposite end would be terminating a “Network” connection(Network Termination).There may be more than one “endpoint” associated with a particularport. If a T1 is connected to the PSTN, some DS0s may be used forlong distance, while others are used for local calls. These wouldconstitute two “endpoints” (trunks) over a single physical port.One HDLC resource is used by each PRI or each Packet Endpoint.
