Connecting a Cable to the ToD Interface
Step 1 Connect one end of a straight-through Ethernet cable to the GPS unit.
Step 2 Connect the other end of the straight-through Ethernet cable to the ToD or 1-PPS port on the RSP of the Cisco ASR 920
Router.
For instructions on how to configure clocking, see the Cisco ASR 920 Series Aggregation Services Routers
Configuration Guide.
Note
Connect to EIA Console Port
The serial console cable kit is not included with the device; it must be ordered separately.
Note
Step 1 Connect the RJ-45 cable to the EIA Console port.
Step 2 Connect the DB-9 end of the console cable to the DB-9 end of the terminal.
Step 3 To communicate with the device, start a terminal emulator application, such as Microsoft Windows Hyper-Terminal.
Configure the software with the following parameters:
• 9600 baud
• 8 data bits
• No parity
• 1 stop-bit
• No flow control
Connect a Management Ethernet Cable
When using the Ethernet Management port in the default mode (speed-auto and duplex-auto), the port operates
in the auto-MDI/MDI-X mode. The port automatically provides the correct signal connectivity through the
Auto-MDI/MDI-X feature, and senses a crossover or straight-through cable and adapts to it.
However, the Ethernet Management port may be configured to a fixed speed (10, 100, or 1000 Mbps) through
command-line interface (CLI) commands. In such a case, the port is forced to operate in the MDI mode.
When in a fixed-speed configuration and MDI mode, use:
• a crossover cable to connect to an MDI port
• a straight-through cable to connect to an MDI-X port
