You can use a T-1, T-3, Metro Ethernet, cable modem or DSL. A cable modem or DSL connection will provide better speeds than a T-1 (1.5Mbit) as well as being cheaper.
Typical pricing is $120 for business class cable modem, $80 for business class DSL and $400 for a T-1.
For the retirement home Internet service to work through the CMTS it will need a network connection that has to have a static IP address. This static IP is necessary to remotely manage, upgrade and monitor the CMTS.
A router needs to be provided to the equipment and capable of port forwarding so the CMTS can be managed remotely.
These are the settings required on the router:
The LAN IP to be 192.168.1.254
DHCP turned off
All the following ports should be forwarded to the IP address of the CMTS which is by default 192.168.1.1
- 80 – TCP: CMTS Web Management
- 20 – TCP: CMTS FTP Server
- 21 – TCP: CMTS FTP Server
- 23 – TCP: CMTS Telnet Server
- 161 – UDP: CMTS SNMP for monitoring
