The BN24H is a twisted-pair (three twisted pairs) cable with a standard 8-pin modular
plug on one end and a 6-pin modified modular plug on the other end. Use this cable to
connect the DECserver 90M+ to an MMJ connector on an asynchronous device. You
also use the BN24H when connecting an asynchronous device to a DECconnect wall
plate.
Use an H8584-AA adapter when connecting the DECserver 90M+ to existing MMJ
wiring. The adapter uses a standard 8-pin modular plug on one side and a 6-pin
modified plug on the other end.
Figure A-3 shows the wiring configuration for the BN24H cable and H8584-AA
adapter.
