LTR-T Installation Guide 1
Overview
The LTR8T and LTR16T are 10BASE-T hub/repeaters that receive Ethernet traffic from
one cable segment and repeat that data to all of the other attached segments. The units
provide 8 (LTR8T) or 16 (LTR16T) RJ-45 connection to 10BASE-T media. The
10BASE-T media is phone-grade (or better) unshielded twisted pair cable, also called
UTP. The hubs also provide one (LTR8T) or two (LTR16T) standard 15-pin AUI
connectors for interfacing to Thickwire media or other media via an external transceiver.
Each 10BASE-T segment can be connected to either a network node or to another
10BASE-T hub for further network distribution.
In the discussions below, the term LTR-T will be used to refer to both the LTR8T and the
LTR16T, which are considered functionally equivalent.
LTR-T Features
The LTR-T has the following features:
• meets IEEE 802.3 repeater specifications.
• 8 or 16 (LTR16T) 10BASE-T ports for direct connection to UTP cable segments
of up to 100 meters each.
• 1 or 2 (LTR16T) AUI ports for attachment of external Thinwire (10BASE2),
Thickwire (10BASE5), or UTP (10BASE-T) transceivers.
• separate status and activity LEDs for each port.
• user-friendly interface allows configuration of link test and polarity correction
and manual partitioning of individual ports.
• automatic port partitioning disables malfunctioning network segments and records
the event to aid in network troubleshooting.
• optional stringent reconnection algorithm for reinstatement of automatically
partitioned ports.
• 1 or 2 (LTR16T) user configurable ports simplify repeater to repeater
connections.
• small physical size.
• easy installation.
Guide to this Manual
The rest of this manual covers unpacking and installation instructions, diagnostics, and
configuration of the LTR-T. Appendix A lists the power supply cord specifications for
use outside the U.S. and Canada. Appendix B explains different kinds of cables you can
use and rules you must follow to set up your network. A glossary is also provided to
explain any unfamiliar terms.
