Page 16: Router 5000 And Ft Router 5000 Overview
The Router 5000 chip and the FT Router 5000 chip (generically referred to as Series 5000 router chips) are Echelon semiconductor products, based on the Echelon Neuron 5000 Core, that are used to build half-routers and full routers for channels. A L...

Echelon provides special licensing for other transceiver types, such as a Power Line Smart Transceiver; contact Echelon Support for additional information. A complete router using the Router 5000 consists of two Router 5000 half routers, two transceivers, and a motherboard to connect the two half routers.
Page 18: Comparing The Rtr-10, Router 5000, And Ft Router 5000
The FT Router 5000 supports only the TP/FT-10 channel, but because the transceiver is integrated into the chip, you do not need to use an FTT-10A Free Topology Transceiver (and associated circuitry to accommodate the different voltage standards between the half router and transceiver).

Page 115: Set Priority Output Buffer Queue Count
The total number of bytes assigned to the buffer queues for a RTR-10 must not exceed 1254 bytes, as described Message Buffers on page 14. The most significant nibble of queue_count is represented by a code of type queue_count_entry: LonWorks Router User’s Guide...
