BSC

BSC protocol allows data flow between nodes over physical links, which are typically channel-to-channel adapters, or leased or dial-up telephone lines.

BSC is a form of line control that uses a standard set of control characters and control character sequences for transmission of binary coded data between systems in a network. A BSC node uses:
  • Remote terminal access method (RTAM) execute channel programming (EXCP) and emulation program (EP) or partitioned emulation programming extension (PEP) in the communications controller
  • Channel-to-channel (CTC) connections are identical to BSC communications except CTC connections do not use EP or PEP. CTC connections are best suited for connections to nodes within the same computer facility.

    NJE protocols support an ESCON Basic Mode CTC (defined to the hardware configuration dialog as BCTC) and a 3088 CTC, but do not support an ESCON CTC (defined to the hardware configuration dialog as SCTC).
