Back Panel Description

All the cable connections to the MultiFRAD are made at the back panel. Four categories of signal
cables are used on the MultiFRAD: Ethernet, Channels, Command Port, and Trunk (RS232/V.35).
The back panel connectors are shown in Figure 1-3 and described in the following groups.
Figure 1-3. Back Panel (FR221/V2)
Voice/Fax Channel 1 and 2 (on FR221/V2 only)
The Voice/Fax Channel connectors include three options per Channel: E&M, FXO and FXS.
E&M - This connector is used if you are connecting VOICE/FAX CHANNEL 1 or 2 to the E&M trunk
on a PBX. This connector is an RJ-48 jack.
FXO - This connector is used if you are connecting VOICE/FAX CHANNEL 1 or 2 to the station side
of a PBX. This connector is an RJ-45 jack.
FXS - This connector is used if you are connecting VOICE/FAX CHANNEL 1 or 2 to a station device,
etc., an analog telephone, KTS telephone system, or fax machine. This connector is an RJ-45 jack.
Ethernet 10Base-T Connector
The Ethernet 10Base-T connector is used to connect the MultiFRAD to a LAN using unshielded
twisted pair (UTP) cable. This connector is an RJ-45 jack.
DSU Connector
The DSU connector is used to connect the MultiFRAD's internal DSU to a trunk connection of a
frame relay network. The DSU connector is an RJ-45 jack.
Command Connector
The Command connector is used to configure the MultiFRAD using a PC with a serial port or terminal
emulation. The Command connector has a DCE physical interface using an RJ-45 jack.
TRUNK Connector (Alternate)
The RS232/V.35 trunk connector can be used for diagnostic point-to-point testing of the MultiFRAD.
This connector is a DB25 female connector.
Channels 1 and 2 Connectors
The two Channel connectors are used to connect data devices to the MultiFRAD. A data device can
be a synchronous device such as a multiplexer or an asynchronous device such as a PC. The data
Channels can be either RS232C or V.35 . If a V.35 connection is desired, then the internal shunt for
that Channel must be physically moved from its default RS232 position to the V.35 position.
Power Connector
The Power connector is used to connect the external power supply to the MultiFRAD. The Power
connector is a 7-pin circular DIN connector. A separate power cord connects the power supply to a
live AC grounded outlet.
