P-2900-4HB User’s Guide

This section describes the information in the Cable Modem Status screen.

In order to establish a successful connection with the cable provider’s network, 
the ZyXEL Device must first find and lock onto two frequencies for communication 
with the cable operator’s network. A frequency is also called a channel. 
Communication with the cable operator’s network cannot proceed until the ZyXEL 
Device locks specific channels for sending and receiving data.

During the provisioning step, your ZyXEL Device passes through several 
negotiation stages with the CMTS, as illustrated in the following figure. The ZyXEL 
Device has to obtain an IP address, set the system’s time/date and download the 
configuration file. If any step fails, the “Waiting for...” message will appear in the 
CM Status screen.
