FEATURES
The Kronback Tracers NDX is used by Cable TV operators to interface distributed Remote
Phy Device (RPD) with equipment in HUBs. It is a 1 rack unit with 3 inputs (NDF) and 6
outputs (NDR). Each of the 6 outputs has 3 NDR carriers, providing a total of 18 NDR
carriers per unit. On each of the 6 outputs 16 RPDs can be combined, providing interface
for a total of 96 RPD´s. In addition to the NDF and NDR interfacing the NDX can receive
the upstream spectrum capture data from each individual RPD.
The NDX supports both IPv4 and IPv6. Interfacing to the CIN consists of 4 x 10GbE SFP+
slots. The NDX is synchronized using the IEEE1588 standard (8275.2 pro
fi
le) Dual hot
swap powersupplys ensures un-interrupted operation. The NDX can be ordered in
115V/230V AC as well as -48V con
fi
guration.
NDF
The NDX provides 3 parallel NDF channels. Each channel can be individually con
fi
gured
to a center frequency between xx and 862 MHz. Mode 0 to 7 are supported. The input
level of each input can be adjusted in a 30dB range to meet the required 1.41 RMS
output level (S6.3 format). The NDF input signal can be monitored by the -20dB test
point output on the front of the NDX, on the LCD screen or from the integrated spectrum
analyzer on the web interface. After the RF input signal has been sampled the data are
packetized as L2TP format and forwarded to the SFP+ interface, with the binding that
NDF1 is sent to SFP+ port 1, NDF2 is sent to SFP+ port 2, NDF1 is sent to SFP+ port 3.
The data output of each individual NDF signal can be either formatted as IPv4 or IPv6.
Both unicast and multicast signaling is supported.
