Product Overview
The base model of a Netlink FRX4000 contains four serial ports for connection to a
frame relay or X.25 network, user devices, and/or other Cabletron frame relay access
devices. (One V.35 DTE interface cable is also included.) Each FRX4000 also con-
tains one LAN interface, either Ethernet or Token Ring. An optional CSU/DSU
interface is also available. (If the CSU/DSU option is used, one serial port is disabled.)
In addition to the four built-in serial ports, an optional expansion card provides one of
the following:
Four V.35 ports
Four RS-232 ports
One T1 port
One E1 port
Four RS-422 ports (available by special request), supporting RS-449 and X.21
interfaces, in any combination (via cables)
Each of the serial ports supports any of the protocols that are installed in an FRX4000.
Each FRX4000 contains software for frame relay, SDLC, SNMP and any additional
protocols that were purchased with the device.
The Ethernet model of the FRX4000 contains an Ethernet interface, provided in RJ-
45 (for twisted pair) and 15-pin "D" (AUI, for Thicknet) configurations. The Ethernet
cable and, if AUI, the tranceiver, must be provided by the customer.
The Token Ring model of FRX4000 contains a Token Ring interface, provided in RJ-
45 (for unshielded twisted pair) and 9-pin "D" (for shielded twisted pair) configura-
tions. A Token Ring cable, part number FRX-TR-CAB, is available from Cabletron.
After it has been installed and configured, an FRX4000 can function with no keyboard
or video device. (Therefore, such devices are not standard equipment.) However, con-
figuration, file copy (backup, restore, transfer, etc.), and monitoring operations require
a keyboard and screen, in one of several forms.
The typical method of connecting to an FRX4000 is via an ASCII (VT100-type) ter-
minal (configured for 9600 bps, 8 data bits, 1 stop bit, no parity), or a terminal emu-
lator on a PC running Procomm Plus for Windows. Each FRX4000 is shipped with
cabling to support connection to an ASCII terminal or a PC.
