The RCS comes factory-configured for EIA-232 on the WAN port. To change the WAN port
interface setting, use the following command.
set wan interface setting
where setting is one of the following: rs232, rs422, e530, v.35. To connect synchronous
modems, ISDN modems, FRADs, or CSU/DSUs to the RCS, use straight-through cables.
Make sure that your cable includes conductors to carry all the signals required for the
interface setting you have chosen. For V.35, you must use an RCS V.35 adapter cable
available from your supplier. Table 3-4 gives the WAN port pinout for EIA-530 mode. Note
that EIA-530 uses a differential pair of wires for each signal and these are denoted “A” and
“B” in this table.

Ethernet LAN
The RCS port server is connected to your LAN using an ethernet port. There are four
ethernet hub ports on the front panel, labeled A, B, C, and LAN. The LAN port is hardwired
as an ethernet peripheral RJ-45 port so that it can conveniently be connected to a HUB using
a standard straight through patch cable. The LAN port is typically used to connect the RCS
to the local ethernet network.
The A, B, and C hub ports are standard ethernet hub ports. Any 10BaseT ethernet device can
be connected to a hub port using a standard straight through patch cable. A hub port is
typically used to connect other devices to the ethernet network. The LAN port can also be
