2-16 Connecting the Cables FCD-E1LC Ver. 1.0
Connecting the Sublink
³ To connect equipment with balanced interface to the FCD-E1LC sublink:
• Use a straight (point-to-point) cable terminated in RJ-45 connectors to
connect the designated equipment connector to the FCD-E1LC RJ-45
connector designated E1/T1 SUB.
One of the contacts in the E1 sub port connector is used to sense the connection
of the unbalanced adapter cable (see below). Therefore, do not connect cables
with more than two pairs when you want to use the balanced interface.
³ To connect equipment with unbalanced interface to the FCD-E1LC sublink:
1. Connect the RJ-45 connector of the CBL-RJ45/2BNC/E1 adapter cable to the
FCD-E1LC RJ-45 connector designated E1/T1 SUB.
2. Connect the coaxial cables from the other equipment to the two BNC
connectors at the other end of the adapter cable. Pay attention to correct
connection:
 Connect the cable from the user’s equipment receive output to the green
BNC connector (sublink transmit input)
 Connect the cable from the user’s equipment transmit input to the red
BNC connector (sublink receive output).
Connecting the Data Channels
Each serial data port of the FCD-E1LC is terminated in a 25-pin D-type female
connector. The interface type is RS-530 (also supporting X.21) or V.35, according
to order.
The required cables can be prepared in accordance with the port connector wiring
information given in
Appendix A , or ordered separately from RAD. See list of
cables available from RAD in
Section 2.4 .
When using adapter cables, first connect the adapter cable to the FCD-E1LC data
channel connector, and then connect the user’s data cable to the adapter
connector.
Connecting Ethernet
Identify the cable intended for connection to the 10/100Base-T connector.
Connect the cable to the corresponding module connector.
Use a standard (station) cable wired point-to-point for connection to any type of
Ethernet port (hub or station).
