Installing the TE3000
15
The illustration indicates the physical locations of pins 1
and 6 within the fault relay port, as viewed from the rear
panel.
When the fault relay detects a fault condition, the fault
relay trips, and the Status LED located on the TE3000
front panel illuminates red.
Transport Connection
Ports
The TE3000 multiplexer outputs an ASI transport stream with a variable rate of 1
to 7 0Mbps. This transport stream is the combination of the video, audio, and
auxiliary data streams in an MPEG-2 compliant transport stream. Depending on
the operating mode, the transport stream is either:
!
Input to the modulator or the multiplexer of another TE3000 where it is
multiplexed with another transport stream before being output
!
Output to an external satellite modulator
Operating Modes
The two TE3000 operator modes are:
!
Single channel per carrier (SCPC)
!
Multiple channel per carrier (MCPC)
SCPC Mode
In SCPC mode, the ASI transport stream is connected from the
TE3000 multiplexer to the internal modulator of the same TE3000. In this mode,
the modulator supports transport stream data rates from 1 up to 18 Mbps in SCPC
mode, depending on the FEC rate selected. Output symbol rates range from 1 to
20 MSps.
MCPC Mode
In MCPC mode, the ASI output of one TE3000 is fed into the
multiplexer of another TE3000 so that the output of the two encoders are
multiplexed in a single transport stream. The signal from a series of TE3000s can
be combined in this way. The combined transport stream is then output to the
modulator of the final TE3000 in the chain.
In MCPC mode, the modulator supports transport stream data rates from 1 to
32 Mbps, depending on the FEC rate selected. Output symbol rates range from 1
to 20 MSps. For applications requiring higher data rates, an external modulator
can be used instead of the TE3000 integrated modulator.
Connections
The TE3000 ports used to connect the transport stream to the modulator and the
MCPC chain are:
!
ASI TS In
!
ASI Out Pri (primary ASI out)
!
ASI Out Sec (secondary ASI out)
!
SMPTE -310
!
Mod ASI In
ASI TS In
ASI TS In is a female BNC connector with 75
Ω
impedance. When
the encoder is configured for MCPC operation, this port accepts the transport
stream from either ASI Out port of another encoder.
