CH (CableHome) Mode provides all the functionality of RG mode and adds the ability of the cable company to
control the home networking configuration of your Wireless Cable Gateway for you, so you don't need to perform
the configuration yourself. In this mode, four IP stacks are active:

IP Stack 1 - for use by the cable company to communicate with the Cable Modem section only. This stack
receives its IP address from the cable company during CM initialization. It uses the MAC address printed on
the label attached to the Wireless Cable Gateway.

IP Stack 3 - for use by your cable company to communicate with the Networking section to help you configure
and manage your home networking. This stack requires an IP address assigned by the cable company from their
pool of available addresses. Your cable company may have you or your installer manually enter assigned
addresses into your gateway, or use a DHCP Server to communicate them, or use a method that involves you
entering host names. This stack uses a MAC address of MAC label + 2 (the MAC label is found on the bottom
of the unit). E.g., if the MAC address is 00:90:64:12:B1:91, this MAC address would be 00:90:64:12: B1:93.

IP Stack 4 - for use by you to remotely (i.e. from somewhere on the WAN side, such as at your remote
workplace) communicate with the Cable Modem and Networking sections, to remotely access the internal web
page diagnostics and configuration. This stack is also used by your cable company to deliver packets between
the Internet and the Wireless Cable Gateway's Networking section so they can be routed to/from your PCs.
This stack requires an IP address assigned by the cable company from their pool of available addresses. Your

address is 00:90:64:12:B1:91, this MAC address would be 00:90: 64:12:B1:94.

IP Stack 5 - for use by you to locally (i.e. from somewhere on the LAN side in your home) communicate with
the Cable Modem and Networking sections, to access the internal web page diagnostics and configuration. This
stack is also used by the Wireless Cable Gateway Networking section to route packets between the Wireless
Cable Gateway's Networking section and your PCs. This stack uses a fixed IP address: 192.168.0.1. It uses a
MAC address of MAC label+ 4 (the MAC label is found on the bottom of the unit). E.g., if the MAC address is
00:90:64:12:B1:91, this MAC address would be 00:90:64:12:B1:95.
With CH Mode, your cable company must provide one IP address for the CM section, plus two for the Networking
section, from their pool of available addresses. Each PC you connect gets an IP address from a DHCP Server that is
part of the Networking section of the gateway.
