Chapter 12
Configuring Async Ports
Introduction
The async PAD function in the FRM allows asynchronous devices to connect to a
frame relay or X.25 network.
Async support includes:
●
Local login passwords
●
Autocall, with dial-in delay ability
●
Autobaud
●
Automatic disconnect on inactivity
●
X.29 support
●
Abbreviated addressing
●
RTS/CTS hardware flow control
To run a port as an integral async PAD in an FRM, make sure the following are con-
figured in the database:
●
Node parameters , which is general configuration that must be done no matter
which protocols will be run in the node. See Chapter 4.
●
RLPs that will contain the interface(s) to the user device(s), plus Line Interface
Card(s) supporting the ports that will be the interfaces. See Chapter 5.
●
Loaded Protocol(s) : Async, plus frame relay or X.25. See Chapter 5 .
●
Frame relay port(s) and/or X.25 port(s) that will connect to a network or frame
relay PVC. See Chapter 7 (frame relay) or Chapter 8 (X.25).
●
Async PAD Profiles (page 12-2), which define the operation of the attached
devices.
●
Login parameters (page 12-6), which define passwords to be used when logging
into the FRM.
●
Async port(s) (page 12-8) that will connect to the user device(s).
●
Subscriber ID(s) (page 12-14), which identifiy user devices to each other and
the FRM.
●
Abbreviated address(es) (page 12-17), if desired. This feature allows short
"nicknames" to be assigned to subscriber addresses, to ease entry of addresses.
●
PVC connection(s) (page 12-17), which create "permanent" connections
between two ports in the node. A PVC can be created between two async ports
or between an async port and an X.25 port.
