Chapter 2. Configuration Overview
This section of the System Configuration Guide features a short overview of each
component/layer of the System including the WMTS and the modems. The last
section is a summary presented as a matrix that shows the relationships between
the various tools and files. The components and layers are described below.
• Network Servers
o DHCP Server
o TFTP Server
o Time of Day (ToD) Server
• RF Link Layer
• DOCSIS Layer
2.1 Network Servers
The following servers are required for successful completion of modem
initialization. They will be accessed by the modem and the WMTS at specific
points during the registration and installation process.
2.1.1 DHCP Server
This server binds the modem’s MAC address to both its Network IP address
and its configuration (or “boot”) file, which contains several important system
specific parameters required for the modem to communicate with the WMTS.
Viewing this information can help in troubleshooting any problems which may
occur.
2.1.2 TFTP Server
This server downloads the selected configuration file to the modem during
the registration process when the modem requests it. It also downloads files
and configuration information to the WMTS. This information is used for
initial (first time) startup and for troubleshooting.
2.1.3 Time-of-Day (TOD) Server
This server provides the Time of Day to the modems and the WMTS. It
allows the WMTS and the modem to coordinate their timing.
2.2 RF Link Layer
This network layer is unique for each installation and depends on the
available frequencies, the frequency plan, the specific hardware used for the
installation, and other factors.
