Using The Tributary Daisy Chain Switch
The 40-792/793 comprises 2 sections (see graphic on
previous page).
1. Daisy-Chain switches. These are used to feed 2M signals
into and out of the DUT (device under test), any selection of
tributaries may be routed (e.g. all even, all odd, etc).
2. Breakout multiplexer. This is used to test a specific
tributary.
The 40-792/793 is programmed as a 4x16 matrix:-
1st row
is used to route the Daisy-Chain switches. The
default setting is for all tributaries to be selected.

3rd row
is used to select the receive multiplexer to a specific
tributary.
4th row is used to select the transmit multiplexer to a specific
tributary.
