FIGURE 40: This diagram illustrates a simplied internal AES3 and
Ethernet data path. The amplier is set to repeat the AES3-A stream
coming from master port 1 to port 2. Notice that AES3 streams are
monodirectional, while data stream is bidirectional.

FIGURE 42: This diagram shows both AES3 data paths in repeater
mode. In this example, the AES3-A streams enters port 2 and is
repeated out of port 1. At the same time, the AES3-B stream is
incoming in port 1 and is repeated outwardly via port 2. All possible
permutations are not displayed.
KEASOP forward mode
When the amplier is set in forward mode, the AES3 signal
coming into the amplier from the rear panel Phoenix connector
is forwarded to both of the master RJ45 ports. There are three
ways the AES can be forwarded:
▶
Forward to AES3-A:
the amplier’s rear panel AES input via the Phoenix connector
will be routed to the AES stream A on both ports 1 and 2. If
there is an AES3-B stream incoming from either port (1 or 2),
this will be repeated on the other port. For example, the gure
below shows the “Forward to AES3-A” function where the AES3
stream coming from the rear Phoenix connector is forwarded to
the AES3-A stream and no AES3-B stream is present.

This gure, on the other hand, illustrates the signal path in
“Forward to AES3-A” mode when an AES3-B stream is present;
the AES3-B stream is, in this example, incoming through master
port 1. The AES3-A stream, if present will be repeated from/to
RJ45 ports 1 and 2.
