Compatible Systems 2270R manual Ethernet Connection Requirements, T1 Line Connection Requirements

Chapter 2 - Getting Started 7

Ethernet Connection Requirements

The MicroRouter 2270R’s Ethernet interfaces directly support 10BaseT twisted-pair Ethernet. Other Ethernet cabling types (such as thin Ethernet, thick Ethernet, fiber optic cabling or pre-10BaseT twisted-pair) can be supported using a 10BaseT mini-hub or other conversion device.

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.

T1 Line Connection Requirements

The MicroRouter 2270R includes an integrated fractional or full T1 CSU/DSU. To connect this interface to a T1 line, you will need an RJ-45 jumper cable. A straight-through Category 5 10BaseT jumper cable will work in this application.

Note: The MicroRouter 2270R includes loopback features which vcan be used to check the functionality of your T1 line. Before attempting to route network traffic, use these features to check the line’s basic integrity.

Other 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 2270R’s vsecondary port to a leased telco line, use the loopback features of your external 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.
