Datasheet

Carrier Class signal-processing
113
U 154
4 x IP to QAM converter
for processing of up to 4 IP multicast groups of a Gigabit Ethernet MPEG TS in
4 standard QAM channels
QAM channels are led through as two adjacent channels
outstanding signal parameters by Direct Digital technology (MER: typ. 44 dB; shoulder
attenuation: typ. 58 dB)
optionally available output channel filters (U-KF) allow for maintaining the high signal
quality even after combining
user friendly configuration via webbrowser
