Cable Connectivity for MAPD

The system assembly is provided with a special amphenol connector, or cable, that is plugged into the back of the ECS at the location occupied by the TN801 (see Figure 13-4). The cable has a female RJ45 receptacle that is used as the 10Base-T Ethernet connection and three DB25 serial connectors. This cable provides Ethernet access and serial access to the MAPD system.

Figure 13-4. Cable Connectivity to the MAPD System Assembly

The MAPD Ethernet 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.

NOTE:

Lucent Technologies strongly recommends (both for security and performance reasons) that the Ethernet connectivity between the MAPD
