Setup

1. Select Technicolor CGM4981COM (Cox Panoramic Gateway PM8 / XB8) in the setup wizard or Settings.
2. Use http://192.168.0.1 unless your gateway is reachable at a different management address.
3. Enter the gateway username and password.
4. Test the modem connection before saving.

Implementation notes

The driver logs in through /check.jst, keeps the DUKSID cookie, then reads downstream and upstream channel data from /network_setup.jst. The parser handles the columnar HTML table layout used by this firmware family.

Troubleshooting

• If login fails, verify that the gateway web UI accepts the same username and password from your browser.
• If the gateway is in bridge mode, confirm that its management IP is still reachable from the DOCSight container.
• If channel data is missing after login succeeds, open a modem support issue with a sanitized HTML sample from the signal/status page.
