1 Product overview
Figure 1- ADP-3G block diagram
The Flashlink ADP-3GHD is a multi bit-rate ADD/DROP/PASS module providing high
performance media distribution for various signal formats from 19.4Mbps up to 2970Mbps.
The unit can be operated as a redundant or dual ADP amplifier configured to do cable
equalizing and reclocking of SMPTE 424M, SMPTE 292M and SMPTE 259M signal formats.
The four inputs typically provide automatic cable equalizing for up to 70 meters of cable
(Belden 1694A at 2970Mbps), with reclockers on all outputs. The ADP-3GHD will detect
3GHD, HD and SD rates and automatically switch to the correct output slew-rate.
The reclockers support the bit-rates 270Mbps, 1483.5Mbps, 1485Mbps 2967Mbps and
2970Mbps. For other rates, the reclockers automatically switch to bypass mode, and the
ADP-3GHD will work as a non-reclocking distribution amplifier with cable equalizers.
The ADP-3GHD also supports reclocking of DVB-ASI at 270Mbps, enabling all possible rates
including empty transport streams with only K28.5 padding packets. All of the outputs are
non-inverting and suitable for DVB-ASI.
In redundant operation the included intelligent change-over feature gives the ability to
change between inputs based on input signal loss, loss of lock, EDH errors or a combination
of the above.
There is also included a passive bypass function from both inputs to non-inverted outputs
with less than 15 m loss of cable length (enables full redundancy in case of mains failure).
The ADP-3GHD is designed for all distribution purposes in studio, duplication and broadcast
applications.
Please observe that ADP-3GHD can not be used with N-Box, Flashlink one module desktop
box, due to mechanical issues.

The ADP-3GHD supports a number of different formats. The correct configuration can either
be set with a DIP switch or with the GYDA system controller. The layout of ADP-3GHD is
shown in the drawing below.

The ADP-3GHD has two backplane options, DA-3GHD-2x4-C3 and DA-3GHD-2x4-C4. The
connector placement of the two are equal, but the –C4 backplanes features passive byass
between IN1 and O1A, and IN2 and O2A. This module is mounted at the rear of the sub-
rack.

8 Change over functionality
The change over functionality is only used when the card is set up for a redundant ring.
The card has a number of signal integrity analyzers and something called "triggers". A trigger
is another way of controlling the change-over functionality. The regular change-over
configuration is used for setting latch on/off, EQ or RCL control etc. In addition, the signal
integrity analyzers can be used to control the decision of which signal to use on the DROP
output. Thus, the trigger is a link from the analyzer to the change-over.
ADP-3GHD has four video analyzers.
Figure 11 - Video analyzer settings
Figure 9 shows the controls for these. The two inputs each have their analyzers, plus an
extra "Stream 2" analyzer that is used when SMPTE 425M Level B mapping is used.
These errors can be counted (or ignored) based on the settings in the configuration view:
Errors are checked once per video field (LOCK errors are counted every 20ms when no
video is present). If an error occurs, it is checked against the bit mask, and if selected for
counting increments the error counter. An SNMP tool is recommended for tracking error
counts over time, with selectable limits on error rate and max count before generating a
warning.
The triggers are using the same information (and therefore have the same bit names as the
analyzers), but have separate bit masks. This means that it is possible to count one set of
error types, while using a different error type to control the change-over.
nevion.com | 13
ADP-3GHD Rev. A
Figure 12 - Video error trigger settings
There is one trigger for each analyzer. Since there are triggers for both the main and standby
input, an error condition on main input doesn't necessarily mean the change-over will switch,
but for simplicity the following description assumes that the standby channel is always
"good".
Each trigger has an adjustable time control, called "hold time". This is used for three
situations:
a) a) Multiple bursts of error within timer duration triggers a switching to standby.
b) b) Single continuous error condition whose duration exceeds timer triggers a
switching to standby.
c) c) Error free periods, whose duration exceeds timer, triggers a switching back to
main.
The trigger also has a setting for "bit operator". It is possible to do a logical AND on the bits
after applying the mask. Set to AND, all the individual error types that have been enabled
must be occurring to count as an error condition. Set to OR, any enabled error type will
suffice.
