Chapter 12Configuring Async PortsIntroductionThe async PAD function in the FRM allows asynchronous devices to connect to aframe relay or X.25 network.Async support includes:l Local login passwordsl Autocall, with dial-in delay abilityl Autobaudl Automatic disconnect on inactivityl X.29 supportl Abbreviated addressingl RTS/CTS hardware flow controlTo run a port as an integral async PAD in an FRM, make sure the following are con-figured in the database:l Node parameters, which is general configuration that must be done no matterwhich protocols will be run in the node. See Chapter 4.l RLPs that will contain the interface(s) to the user device(s), plus Line InterfaceCard(s) supporting the ports that will be the interfaces. See Chapter 5.l Loaded Protocol(s): Async, plus frame relay or X.25. See Chapter 5 .l Frame relay port(s) and/or X.25 port(s) that will connect to a network or framerelay PVC. See Chapter 7 (frame relay) or Chapter 8 (X.25).l Async PAD Profiles (page 12-2), which define the operation of the attacheddevices.l Login parameters (page 12-6), which define passwords to be used when logginginto the FRM.l Async port(s) (page 12-8) that will connect to the user device(s).l Subscriber ID(s) (page 12-14), which identifiy user devices to each other andthe FRM.l Abbreviated address(es) (page 12-17), if desired. This feature allows short"nicknames" to be assigned to subscriber addresses, to ease entry of addresses.l PVC connection(s) (page 12-17), which create "permanent" connectionsbetween two ports in the node. A PVC can be created between two async portsor between an async port and an X.25 port.
