Configuring BSC Interactive
Introduction
The FRM supports BSC (binary synchronous communication) Interactive ports, used
to connect IBM 3270 hosts to remoteCUs (control units) (via HPAD-TPAD commu-
nication) over frame relay or X.25. IBM's DSP (Display System Protocol) allows a
host-to-TPAD connection across the network.
BSC Interactive support includes:
●
Full-duplex line control
●
Point-to-point and multipoint operation on BSC Interactive ports
●
Autocall from BSC Interactive TPAD port
●
Each BSC Interactive HPAD supports up to 16 remote TPADs simultaneously
●
Each TPAD supports up to 32 CUs per multidrop line
To run BSC Interactive in an FRM, make sure the following are properly configured
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)
: BSCI, as well as the transport protocol: 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).
●
BSC Interactive port(s)
(page 10-2) that will connect to the user devices.
●
Subscriber IDs
(page 10-8) to identify the user devices.
