HAPTER ETTING
COAX (10Base2 Coaxial Port) – The coaxial LAN port
allows a 10Base2 Ethernet segment to be connected
directly to the OfficeConnect Remote. If the unit is to
be installed at the end of a cable run, then a 50 Ohm
terminator must be fitted to the 10Base2 cable
connector. This port can be used to connect to
OfficeConnect hubs.
MDI/MDIX Switch Affects the operation of the
10BaseT LAN port. If you are connecting to a hub, leave
the switch in the In position. If you are connecting to a
single PC, set the switch to the Out position to
implement the 10BaseT crossover that is required.
WAN (OfficeConnect Remote 520 and 530 only)
This port is used to provide connection to a WAN, via
a private leased line. The port terminates with a
25-way D-type female connector. This port supports
any of the CCITT data transmission standards;
X.21/V.11 V.24/V.28 (RS232), and V.35/V.36 at data
transfer rates up to 2 Mbps. Provided that connection
cables that follow these standards are used, the
OfficeConnect Remote automatically detects the
type of interface that the port is required to support,
and configure it accordingly.

interface cables required. Suitable cables are available
from your 3Com reseller as spare parts, refer to
Appendix B for required item part number
10BASET This RJ45 port is to the left of the ISDN socket
when looking at the rear of the unit and is used to
provide a connection to a 10BaseT LAN. This socket
allows direct connection between the OfficeConnect
Remote and a single piece of equipment, as opposed to
multi-point LAN connections using 10Base2 cabling
systems. The OfficeConnect Remote LAN port simulates
the characteristics of a workstation port, which allows it
to be directly connected to a LAN or network hub port
as required.
If the LAN port is to be connected directly to a single
PC or workstation, then you must implement the
crossover by setting the MDI/MDIX switch to the out
position. See "MDI/MDIX Switch" for more
information.
ISDN This port is used to connect to the ISDN network.
The port uses an RJ45 connection socket situated to the
left of the 10BaseT LAN socket. A standard ISDN line
wall socket is required to connect the ISDN cable to the
ISDN port of the OfficeConnect Remote.
