Gps Port Pinout; Time Of Day Pinout - Cisco ASR 907 Hardware Installation Manual

GPS Port Pinout

GPS Port Pinout
The platform is capable of receiving or sourcing GPS signals of 1 PPS & 10 MHz. These interfaces are
provided by two mini-coax 50-Ohm, 1.0/2.3 DIN series connector on the front panel. Similarly there are two
mini-coax 50-Ohm connectors provided in the front panel to output this 1PPS and 10MHz.
The table below summarizes the GPS port pinouts.
