10Base-T Twisted-Pair Ethernet

To connect the router's Ethernet interface to twisted-pair Ethernet cabling you will need an unshielded twisted-pair station cable that is connected to a 10BaseT-compatible twisted-pair hub.

Note: Ethernet cables and cable connectors are not supplied with vthe MicroRouter product. Please contact your reseller or your Compatible Systems representative for information on obtaining the correct Ethernet cabling supplies.

Telco Line Connection Requirements

In order to connect to non-T1 wide area transmission lines, you must connect the router’s secondary wide area port to a modem, 56K CSU/DSU, or ISDN Terminal Adapter. Which of these devices you use depends on the type of telco line.

Note: Before attempting to connect the MicroRouter 2200R to a vleased telco line, use the loopback features of your CSU/DSU to check the line. This can save you a considerable amount of time, since the more equipment you have on the line, the more difficult it becomes to determine where a problem is occurring.

The MicroRouter 2200R provides one high-speed V.35 synchronous interface, and one RS-232 sync/async interface, each of which can be independently configured for PPP, Frame Relay or SMDS operation. The V.35 interface is capable of communicating to another router or a PPP client machine over a 56K CSU/DSU, an ISDN Terminal Adapter, or a T1 CSU/DSU. The RS-232 interface is capable of communicating to another router or a PPP client machine over a modem, 56K CSU/DSU, or ISDN Terminal Adapter.

V.35 Interface

The MicroRouter 2200R does not include a V.35 cable. These cables are available from your reseller, or a number of other suppliers. The MicroRouter 2200R has a female V.35 connector, as do virtually all line communications devices. Thus, the V.35 cable required to connect to a line communications device will usually have male connectors at both ends. The pinouts for this cable are shown in Appendix B.
