5.5 Clock Cable
This section describes the structure and technical specifications of the clock cable.
5.5.1 Introduction
Clock cable for the 1588v2-supporting.
A clock cable is used to connect the clock interface on the CX600 to the clock interface on
another device. In the case of the CX600 be equipped with one MPU, the CX600 can receive
one channel 2-Mbit/s clock signals, one channel 2-MHz clock signals, one channel 1 PPS +TOD
time signals, or one channel of input and one channel of output DCLS time signals from the
upstream device and provides one channel 2-Mbit/s clock signals, one channel 2-MHz clock
signals, one channel 1 PPS +TOD time signals, or one channel of input and one channel of output
DCLS time signals to the downstream device. In the case of the CX600 be equipped with two
MPUs, the CX600 can receive two channels 2-Mbit/s clock signals, two channels 2-MHz clock
signals, two channels 1 PPS +TOD time signals, or two channels of input and two channels of
output DCLS time signals from the upstream device and provides two channels 2-Mbit/s clock
signals, two channels 2-MHz clock signals, two channels 1 PPS +TOD time signals, or two
channels of input and two channels of output DCLS time signals to the downstream device.
One end of the clock cable is an RJ45 connector connected to the clock interface on the MPU
and the other end is connected to the clock interface on an external device. The connector on
the other end needs to be prepared as required on site.
An RJ45 connector is used together with the 120-ohm trunk cable.
NOTE
The wire sequence of a trunk cable used as a clock cable differs from the wire sequence of an ordinary
twisted cable.
