NEC X1832B: FOTS DS3 channel unit with path, line and monitoring markings.

The NEC X1832B is a DS3 channel unit from the FOTS range, designated FOTS-DS3 CH, with path, line and monitoring markings. Channel units are the boards that present individual tributary circuits to the transmission terminal, and a DS3 unit handles the 44.736 Mbit/s rate used across North American networks. The B suffix marks the build issue, and issues are not always interchangeable within one shelf.

NEC’s FOTS range, short for Fiber Optic Transmission System, was the company’s optical line equipment for carrier and utility networks, deployed heavily in North America alongside the FD series digital radio and multiplex products. A terminal is built from multiplexer and demultiplexer units, channel units for the tributary rates carried, alarm control units and power supplies, all mounted in a common shelf. The X-prefixed codes identify those individual plug-in units.
