Pro Fec (Tt1260/Ip/Profec); Hardware Enabled Options (Miscellaneous Cards); High Speed Rs-422 Data Input (Tt1260/Hwo/Hsdata); Alarm Relay Card (Tt1260/Hdc/Alrm) - TANDBERG TT1260 Reference Manual

Options
An IF monitor BNC input is provided with the TT1260/HWO/DVBS2/ASI/IF/C option. This
option also gives a constellation I and Q monitor output
mode disables the ability of the IRD to decode a service.

PRO FEC (TT1260/IP/PROFEC)

The Pro-MPEG Forward Error Correction (FEC) scheme is designed to recover lost or
corrupted packets caused when transferring MPEG-2 transport streams, or newer MPEG
standards encapsulated as MPEG-2 transport streams, over an IP network. The Pro-MPEG
FEC scheme has been implemented to the Pro-MPEG Code of Practice #3 release 2.

Hardware Enabled Options (Miscellaneous Cards)

6.3.1

High Speed RS-422 Data Input (TT1260/HWO/HSDATA)

High-speed data (synchronous data) can be carried in a transport stream as private data. This
is then extracted from the transport stream and output from the IRD via an RS-422 interface or
Ethernet.
6.3.2

Alarm Relay Card (TT1260/HDC/ALRM)

The Alarm Relay Card has six additional relays. The alarm relays are programmable to reflect
the state of one or more of the individual monitored alarm conditions. The relay card provides
a 25-way, D-type connector at the rear of the unit.
NOTE...
Without this option, only the summary alarm is available.
