be daisy-chained with the input/output of a
module being added to the input/output of
all the preceding modules thus eliminating the
need for RF splitters and combiners.
y Configuration and Control of the modules
can either be done through the handheld
controller or from any Internet connection with
the use of the CDC headend controller module.
The remote control of the system provides two
easy to use options with the TSuite computer
application or through any internet browser for
maximum customer choice.
3 - Main features
y TWIN modules (two independent tuners
per module) allowing up to 14 transcoded
transponders/channels per chassis.
y User friendly interface allowing simple selection
of which ATSC or QAM input transponder is
output on which QAM channel including the
service list of each input (names and channel
numbers).
y
Two completely independent and fully agile
outputs from 12 to 1002 MHZ for easier
organization of wider-than-6MHz QAM carriers.
y
Edition of PSIP information including selection
of output VCT table (original, TVCT or CVCT) and
edition of channel names and virtual channel
numbers (processing and multiplexing modes).
y Multiplexing of input services allowing two
input ATSC signals to be transmodulated into
a single QAM output (multiplexing mode)
ambient temperature is maintained in the
manufacturer specified operating range.
2 - Description
y
The T.0X Series is a complete family of digital
cable headend products. These products
include satellite QPSK/8PSK to QAM and ATSC/
QAM to QAM transmodulators, universal
modulators and fiber optic transmitters/
receivers, amplifiers, and splitters. The T.0X
family of products all fit in a standard 19” rack
chassis that contains a power supply and room
for 7 modules.
y
Each of the T.0X DUAL ATSC/QAM to QAM
modules contain 2 completely independent
transmodulators with output frequencies able
to be set independently across the entire range
in order to provide maximum flexibility.
y
Three working modes are provided for
maximum flexibility and easy of use:
transparent, processing and multiplexing. Each
one provides different processing levels of the
input signal. In
transparent mode
each QAM
output signal is the same as the corresponding
input ATSC or QAM signal, except for baud rate
adaptation. In processing mode some edition
is possible in the PSIP information (service name
and virtual channel number). In
multiplexing
mode
, in addition toi PSIP edition, each input
service can be directed to any of the two
outputs or eliminated if not desired.
y Additionally, both inputs and outputs can
deleting services if necessary.
y
64/256 QAM annex B and up to 1024 QAM
annex A.
y
Remotely upgradeable firmware allows for
future updates without having to visit the
headend.
y
Carrier wave and null packets output mode for
easy system balancing without an input signal
or without a digital meter.
y Extensive monitoring information for easy
troubleshooting (current and lowest input
SNR, current and highest temperature reached,
number of lock loss conditions over a period of
time, etc.) with LED indicators on the front of
the unit.
y
Back-lit LCD display handheld programmer or
TSuite PC application options for both on-site
and remote configuration and troubleshooting.
y
Copy configurations from one module to
another with the handheld programmer for fast
and easy module swaps (copy/paste).
y
Web page configuration and remote
management using the CDC system.
y
Input/Output daisy-chain architecture to avoid
external splitters/ combiners.
y
RF output loop disable to increase output level
if necessary (external combiner required).
y
High performance, MER>40dB over the full
frequency range of 12 - 1002 MHz.
y
High output level, greater than 43 dBmV with
over 20dB of attenuation margin for easy
balance and integration.
