3.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
Acquire Downstream Channel
In order to establish a successful connection with the cable provider’s network,
the ZyXEL Device must first find and lock onto a frequency for communication
with the cable operator’s network. The frequency is called a channel.
Communication with the cable operator’s network cannot proceed until the ZyXEL
Device finds the specific channel for sending and receiving data.
Connectivity State
The connectivity state is the current status of the connection between the cable
modem and your cable operator. During the initial negotiation with your cable
operator’s CMTS (Cable Modem Termination System), the ZyXEL Device must
establish a clear upstream and downstream channel, which it accomplishes in a
series of well defined steps.
