QTM (QAM Transcoder Module) accepts one input in QPSK or 8PSK format, and delivers one output in
QAM format in the 54-864 MHz range.
The four available models are:
1. QTM-II - accepts one input in QPSK format, and delivers one output in QAM 64 mode.
2. QTM-HD - accepts one input in QPSK or 8PSK format, and delivers on output in QAM 256 mode.
3. QTM-HD PLUS - the same as QTM-HD, but capable of QAM 512/1024 modes.
4. QTM-HD NPU - the same as QTM-HD, but with a “Null Packet” feature that allows adding/removing
null packets to/from the input stream.
Features
• Supports the 8PSK modulation typically used for
High-Definition TV programming
• Supports ITU-T J.83 Annex A and Annex B standards
(QAM 16, 32, 64, 128, 256, 512, and 1024)
• Compact design allows for deployment of 8
transcoders, and power & control module, in 3RU
rack space
• Optional Headend Web Server allows for remote
monitoring and control of each transcoder
• Optional Standby Power Supply allows for uninter-
rupted service in the unlikely event of a primary
power supply failure
