Connecting a Timing Cable to the E4G-400 Router

The front panel of the E4G-400 router provides the following types of cable connections for connecting a Building Integrated Timing Supply (BITS) or a GPS timing source:

Two mini-BNC connectors labeled IN
- 1 PPS input
- 10 MHz input
Two mini-BNC connectors labeled OUT
- 1 PPS or 8 KHz frame output
- 10 MHz or 2.048 MHz or 1.544 MHz output
To connect to the mini-BNC connectors, use a 50-ohm coaxial cable with a mini-BNC connector at one end and a standard BNC connector at the other end.
One RJ-45 connector for time-of-day (ToD) input/output or for RJ422 BITS input
To connect to the RJ-45 connector, use a twisted-pair cable with the pinouts listed in E4G-200 Clock Module RJ-45 Connector.
