Digital Microwave 16x2Mb/s to 34MB/s multiplexer

This page contains rather random info related to some old DMC PDH kit recovered from a building stripout.

It seems to consist of four 2MB/s tribs multiplexed to 8MB/s and then four of the 8Mb/s multiplexed to create the 34MB/s signal which leaves the device on single mode fibre.
