1.3 EMC39-12 OVERVIEW

The EMC39-12 converts Ethernet IEEE 802.3 10BASE-T signals to Ethernet IEEE 802.3j 10BASE-FL signals. The rear panel has a 50-pin Champ connector (RJ71) that supports twelve twisted pair segments. The front panel has twelve 10BASE-FL single mode ST ports. Figure 1-1 shows the EMC39-12 ports. The 10BASE-FL connectors are backward compatible with FOIRL connectors.

Each of the rear panel twisted pair ports has a corresponding ﬁber port. For example: Twisted pair Port 1 converts signals to ﬁber optic port 1, twisted pair port 2 converts signals to ﬁber optic port 2, etc.

EMC39-12 Features

1.4 EMC39-12 FEATURES

The EMC39-12 Ethernet Media Converter pro vides connecti vity for up to twelve singlemode ﬁber optic connections. The network connection is made through a 50-pin connector on the rear of the unit.

The EMC39-12 supports the following:

• Automatic Transmit Port Disable

• Full Duplex Ethernet Support

• LANVIEW Diagnostic LEDs

• Connectivity

The following sections discuss these features.

1.4.1 Automatic Transmit Port Disable

The EMC39-12 automatically disables the Transmit port when its corresponding Receive port does not have a link.

1.4.2 Full Duplex Ethernet Support

All of the EMC39-12 ports support Full Duplex Ethernet provided that the device at the other end of the port supports Full Duplex Ethernet also. Full Duplex Ethernet allows the EMC39-12 to transmit and receive signals simultaneously for a 20 Megabit bandwidth through-put.

1.4.3 LANVIEW Diagnostic LEDs

Cabletron Systems equips the EMC39-12 with a visual diagnostic and monitoring system called LANVIEW . LANVIEW LEDs help you quickly identify Power and Link status. Chapter 4 describes the LEDs in detail.

1.4.4 Connectivity

The rear panel of the EMC39-12 has a 50-pin Champ connector (RJ71) that supports twelve twisted pair segments. The front panel has twelve 10BASE-FL single mode ST ports. Each single mode ST port has a Receive connector and a Transmit connector.
