Signal Status

Signal Status lets you follow the startup procedure and get details on the Downstream and

Upstream cable channel.

Figure 1. Startup, downstream, and upstream information

Use the Signal Status screen to track the gateway’s initialization procedure, and to get details

about the downstream and upstream cable channel. The time is displayed after the gateway

is initialized.

The gateway automatically goes through the following steps in the provisioning process:

Scan and lock the downstream frequency, and then link back in upstream direction.

•

Obtain an IP address for the gateway itself. Then the gateway assigns an IP address for

the connected PC.

•

Connect to the Internet.
