Nieczyporowski, staff specialist, and Wen Huang, staff analyst, developed emulations of the low order bisync
and SNA device types.
The NMS loads and controls the performance monitor, which automatically adapts to various protocols, including Univac and IBM 3270 Bisync
CAM communicates with non-IBM machines in addition to SNA and pre-SNA IBM hosts, and supports most of the popular start/stop, bisync
and SNA-type terminals.
The 3703 may be configured with up to 12 ports, any of which is capable of interconnecting a different kinds of ASCII and/or bisync
device, with all devices communicating with the host over a single SDLC link.
But in the case of IBM's 3270 Bisync
, a positive-acknowledgement protocol, these delays can be overwhelming to the point of rendering multidrop lines useless.
In Figure 1, one can see the normal data line monitor display of Bisync
The new OAS document transfer capabilities allow documents to be sent between OAS systems and non-OAS systems using Honeywell's DSA and IBM's SNA and bisync
NCP is responsible for handling the line protocols, which could be 3270 bisync
in addition to Synchronous Data-Link Control (SDLC), to the cluster controlers and other FEPs.
In addition to SNA terminals, the network supports bisync
3270 and selected asynchronous terminals.
