The ports connected to link jack A is the first set of ports, to link jack
B is the second set of ports, and so on.
For example, under the UNIX 3.2 device driver, ports connected to
link jack A are ttyaa through ttyax, ports connected to link jack B
are ttyba through ttybx, and so forth.
Note that cluster multiplexers may be connected to any link jack;
however, care must be taken in the software to ensure that the proper
set(s) of devices have been enabled.
Each link jack connects to a cluster multiplexer with unshielded two-
twisted-pair cable as shown in Figures 3-1A and 3-1B. As a conve-
nience, each cluster multiplexer is packaged with two crimp-on RJ-11
modular wire adaptors.
