Cable Connectivity for MFB
The system assembly is provided with two special amphenol connectors, or
cables, that are plugged into the back of the ECS at the locations occupied by the
TN2170 and TN2208 (see Figure 13-2). One cable has a female RJ45 receptacle
that is used as the 10Base-T Ethernet connection. This cable is attached to the
TN2170. The other cable consists of DB25 serial connectors and is attached to
the TN2208. These cables provide Ethernet access and serial access to the
DEFINITY LAN Gateway system assembly.

Cable Connectivity to the System Assembly
The DEFINITY LAN Gateway cable is attached to a “demarcation point” within
25 feet of the ECS, consisting of a WE-104 terminal block with 2 RJ45 connectors
punched-down back-to-back so as to provide a “straight-through” connection. The
terminal block, in turn, should be attached using suitable 10Base-T category 3 or
better wiring to an Ethernet hub or an Ethernet hub adapter in the host to which
physical connectivity is desired.
