NPT-1020 Installation and Maintenance Manual

3.5.6 TOD/1PPS Cable

The NPT-1020 platform uses an RJ-45 connector on its front panel, marked TOD/1PPS, which provides
timing and synchronization input/output signals, supporting IEEE 1588v2 standard.
If it has balanced (120 Ω) G.703 interfaces, a multi twisted-pair cable with an RJ-45 connector (supplied by
ECI) is used to connect timing signals from the NPT-1020 to the site timing reference distribution
subsystems.
If the site timing reference distribution subsystem has unbalanced (75 Ω) G.703 interfaces, configure an
adapter with coaxial cables that provides balanced-to-unbalanced conversion (supplied by ECI).

3.5.7 Electric Traffic Cables

Some electric traffic cables can be prepared on site. The following table lists the type of cables and mating
connectors needed for each NPT-1020 traffic interface type.
