NAS BSC 2780/3780 contention mode terminal support utilizes the international Binary
Synchronous Packet Assembler and Disassembly (BPAD) transport protocol. Network BPAD
terminals can access EP-based host applications such as HASP or JES. To the host, the BPAD
terminals appear as dial-in RJE stations. DIAL CCW support is provided in order to allow
the host to initiate calls to BPAD terminals or other BPAD hosts.
