Model TC8300   4-Channel T1/El Fiber Optic Multiplexer    Features 4 Channels of T1, E1 or Any Combination Up to 8 Extra RS-232 Data Channels (optional) Built-In Elastic Buffer and Jitter Attenuator to Remove Jitter Each Channel Supports AMI/B8ZS/HDB3 Line Codes 12 dB Optic Loss Budget Multimode or Single Mode Field Replaceable Line Interface Modules 14 dB of Line Return Loss Distances to T1 (DSX-1) Cross Connect Can Be 0 to 655 Feet Individual Local & Remote Loopback Test 4 LED Indicators for Each Channel to Ease Installation & Trouble-Shooting Process Rack Mount & Stand Alone Versions  Description The Model TC8300 is a 4-channel T1/El Fiber Optic Multiplexer that offers advanced features such as Jitter Removal and a replaceable Line Interface Module. Because it is based on modern FPGA (field programmable gate array) technology, it offers optimum flexibility, extremely low current consumption and high reliability. Transparent to the framing format, the TC8300's T1/El interface shapes the transmit pulse to support CCITT G.703. Line distances for connecting to DSX-l cross connects can be from 0 to 655 feet. The internal elastic buffer removes jitter from transmit data. Each channel offers four LED indicators to ease installation and trouble shooting one each for Power, Alarm, T1/El Signal Loss, BPV violations and Sync Active. Individual channels provide 8 DIP switches, accessible from the panel, to control settings for line code, line length, local loopback or remote loopback. Each channel's flashing alarm LED will indicate any invalid DIP switch setting such as when the line code does not match the line length setting. The intelligent line code setting switch will eliminate any confusion. The TC8300 is compatible with all popular types and sizes of optic cable. Fiber optic connectors are ST; FC or SMA are optional. Special four-position and two-position feed-thru detachable terminals are provided for connecting the T1/E1 twisted pairs. Input power is12VDC or 115/23OVA-with an external power cube.
