2.3 Back Panel
The cable connections for the MultiFRAD are made at the back panel.
Two cable connections are provided and one power supply connection.
The Data connector allows the MultiFRAD to be connected to a non-
frame relay device and the Trunk connector connects to a common
carrier frame relay network service or private frame relay networks. The
cable connections are shown in Figure 2-2 and defined in the following
sections.

Power Connector
The Power connector is used to connect the external wall type trans-
former power supply to the MultiFRAD. The wall transformer plugs
directly into an AC outlet.
Trunk Connector
The Trunk connector is used to connect the MultiFRAD to a 56K DDS
circuit that provides the local access to the frame relay service. This
connector is a RJ48-keyed jack on the back panel of the unit.
Data Connector
The Data connector is used to connect the MultiFRAD to a non-frame
relay device, such as, multiplexers, routers, or legacy equipment such
as cluster controllers, or an asynchronous device such as a PC running
remote control software. A second use of this connector is to configure
the MultiFRAD. The Data connector is a DB-25 female connector
located on the back panel of the MultiFRAD.
The Data connector interface can be either an RS-232C or V.35 inter-
face. When the V.35 interface is used, the data shunt has to be moved
from the default RS232 position to the V.35 position. Refer to "Shunt" in
this chapter for changing the data shunt. Refer to Appendix A for
cabling requirements in V.35 mode.
