Page 4: Overview
Overview Thank you for choosing the Metrobility T3/E3 media converter. The Metrobility T3/E3 media converter from Systems provides high-speed inte- gration and conversion of T3 (44.736Mpbs) or E3 (34.368Mbps) coaxial telco com- munication lines to fiber transport environments. The copper data stream is converted to optical signals for greater noise immunity and longer transmission. -
Page 5: Installation Guide
Installation Guide Follow the simple steps outlined in this section to install and start using your Metrobility T3/E3 media converter. Unpack the Media Converter and Accessories Check that the following components have been included with your order: • Metrobility T3/E3 media converter •... -
Page 6: Step 3: Set The Switches
Set the Switches A set of DIP switches is located on the back of the unit. On the T3 models, functional switches are clearly labeled and allow you to select from several modes of operation. On the E3 models, only the switches labeled CLP and FLP are functional. -
Page 7: Step 4: Connect To The Network
Connect to the Network The Metrobility T3/E3 model offers the ease of plug-and-play installation. Once power is applied to the unit, correct connectivity can be verified via the link (LK) LED. To connect to the network, insert the cables into the appropriate connectors as illustrated below. - Page 8 Coaxial Interface The coaxial interface provides two BNC connectors. The receive port is labeled RX and the transmit port is labeled TX. Each connector supports a maximum segment length of 1200 feet. Use only RG-59 cables. Fiber Optic Interface 2115-23-01, 2115-25-01, 2175-23-01 and 2175-25-01: The fiber optic multimode (MM) interface supports a maximum segment length of 2km for remote links.

Page 11: User Guide
User Guide This section contains more detailed information regarding the operating features of the Metrobility T3/E3 media converter. LED Indicators The Metrobility T3/E3 media converter provides several LEDs on the front panel for the visible verification of unit status and proper functionality. These LEDs can aid in troubleshooting and overall network diagnosis and management. -
Page 12: Theory Of Operation
Theory of Operation Functional Block Diagram Line Fiber Interface FPGA Optic Coaxial Fiber Unit Circuit VCXO Line Transformers Coaxial to Fiber Data Path The receive (RX) port on the coaxial interface accepts an electrical signal. This signal is coupled to the line interface unit (LIU) through a line transformer. The LIU performs clock and data recovery and converts the signal into non-return to zero (NRZ) data and clock. - Page 13 Local Remote T3/E3 T3/E3 Coaxial Fiber Coaxial Unit Unit The following table describes how timing is affected if a failure occurs at various points in the network. s ' r n i l s ' t s t i s t i v i t , y l l i a...

Page 14: Link Loss Indications
Link Loss Indications The following examples show the status of the LK LED under various link condi- tions and describe when unframed all ones are generated. (Loopback is disabled in these examples.) Note: An all-ones pattern indicates an alarm indication signal (AIS) for the E3 units only. - Page 15 Local T3/E3 Remote T3/E3 Remote Local Unit Unit Device Device Coax Fiber Coax All Ones green LED unlit LED Remote Coaxial Link Loss Loss of link to the remote device produces a red alarm condition at the remote site and should force the device to revert to its internal clock. If the remote device is configured to send back a yellow alarm under this condition, the two T3/E3 units will carry the alarm forward to the local device, as shown below.

Page 16: Loopback Modes
Loopback Modes The Metrobility T3/E3 media converter features two loopback modes to help verify correct installation and to diagnose system problems. Normal During normal operation, without loopback, data from a local device (CSU, PBX, etc.) enters the local T3/E3 unitʼs coaxial receiver, passes through the fiber line be- tween the two converters, then exits the remote unitʼs coaxial transmitter to enter the remote equipment, and vice versa. - Page 17 Fiber Loopback In this mode, the incoming data and clock on the fiber line are looped back. The loop occurs in the FPGA. The data is still sent out the coaxial transmitter. How- ever, the data received at the BNC interface is ignored. In the example below, the remote T3/E3 unit has fiber loopback enabled.
