Page 4: Overview
Overview Thank you for choosing the Radiance T3/E3 single interface line card. The Metrobility Radiance T3/E3 line card provides high-speed integration and conversion of T3 (44.736Mpbs) or E3 (34.368Mbps) coaxial telco communica- tion 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 Radiance T3/E3 single interface line card. NOTE: Electrostatic discharge precautions should be taken when handling any line card. Proper grounding is recommended (i.e., wear a wrist strap). Unpack the Line Card Your order has been provided with the safest possible packaging, but shipping damage does occasionally occur. -
Page 6: Step 3: Install The Line Card
LBO Switch (functional only on T3 cards) Set the Line Build Out (LBO) switch up to support a long haul connec- tion if the length of your coaxial cable is between 255 and 1200 feet. Set LBO down to support a short haul connection if the length of your coaxial cable is between 0 and 255 feet. -

The transmit (TX) port is located above the receive (RX) port. Each connector supports a maximum segment length of 1200 feet. Use only RG-59 cables. Fiber Optic Interface The line card’s fiber optic receive (RX) port is located above its transmit (TX) port.

Page 9: User Guide
User Guide This section contains more detailed information regarding the operating features of the Radiance T3/E3 single interface line card. LED Indicators The Radiance T3/E3 single interface line card provides several LEDs for the visible verification of unit status and proper functionality. These LEDs can aid in troubleshooting and overall network diagnosis and management. -
Page 10: Theory Of Operation
Theory of Operation Data Transparency The Radiance T3/E3 single interface line card offers full data transparency. Any codes or commands contained within the data stream are passed through to the remote device. The only commands executed by the T3/E3 card are those set through the hardware (i.e., DIP switches) or software, which communicates with the card via the management bus on the chassis backplane. - Page 11 Timing Paths The transmit (TX) and receive (RX) paths are clocked independently and during normal operation, the Radiance T3/E3 line cards are never timing masters of the network system. In the coaxial to fiber path, timing is recovered by the card’s LIU and transmitted over the fiber line to the remote T3/E3 line card.

Page 14: Link Loss Indications
Link Loss Indications The following examples show the status of the LK LED under various link conditions and describe when unframed all ones (AIS for E3 only) are gener- ated. (Loopback is disabled in these examples.) Normal The diagram below shows a typical configuration with good link status. Local T3/E3 Remote T3/E3 Remote... - Page 15 Remote Output 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 (AIS) under this condition, the two Radiance T3/E3 line cards will carry the alarm forward to the local device, as shown below.

Page 16: Loopback Modes
Loopback Modes The Radiance T3/E3 line card 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 line card’s coaxial receiver, passes through the fiber line between the two cards, then exits the remote card’s coaxial transmitter to enter the remote equipment, and vice versa. - Page 17 Remote Remote T3/E3 Local T3/E3 Card Local Device Card with Copper Loopback Device Coax Coax Fiber 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 transmit- ter.
