Page of GC20-1801-10 As Updated March 3, 1980 by TNL GN25-0776 Configurations (TCUs) 3704/3705 REQUIRED FEATURES The 3704 and 3705 Communications Controllers are supported in
Netwcrk Control Program mode, Partitioned Emulation Program mode, and 2701, 2702, 2703 Emulation Program mode. VK/370 supports the CPT-TWX (Kodel 33/35) terminals at 110 bps and
the 3101 display terminals at 110, 150, 300, and 600 bps, when attached
to a 3704 or 3705. VK/370 supports all models of the 3704 and 3705 Communications Controllers. However, because the network control program and
partitioned emulaticn program require 48K of storage, the following
models are suppcrted for the emulation program only. IBM 3704 Communications Controller Models Al and A2 IBM 3705-1 Communications Controller Models Al, Bl, Cl, and Dl IBM 3705-11 Communications Controllers, Models El, Fl, Gl, and Hl. The features required on a communications controller do not depend on VM/370. VM/370, when supporting network control mode, requires a
communications controller with at least 48K of storage. Other 3704/3705 features depend upon the intended use of the communications controller
and the type of 3704/3705 control program (emulation, network control,
or partitioned emulation program) to be executed. VM/370 does not support the following 3704/3705 features: Line Set Type 2A (#4721) Line Set Type 3A (#4731) Line Set Type 4B (#4742)
