CableHome (CH) Mode
CH (CableHome) Mode provides all the functionality of RG mode and adds the ability of the cable
company to control the home networking confi guration of your Wireless Cable Gateway for you,
so you don’t need to perform the confi guration 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 confi gure 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.
