Connecting the WAN
To connect the Gateway to a Wide Area Network (WAN) interface:
3. Connect a coaxial cable to the port labeled Cable on the rear panel of the Gateway from a
cable port in your home or office (see Figure 2 on page 15). Use only manufactured coaxial
patch cables with F-type connectors at both ends for all connections.
4. Hand-tighten the connectors to secure the connection.
5. If the modem was not installed by your cable provider (ISP) or is replacing another cable
modem, contact your cable operator to register the SMCD3GNV. If the modem is not
registered with your cable operator, it will be unable to connect to the cable network
system.
Connecting to the Public Telephone Network
The rear panel of the Gateway has two RJ-11 telephone-style connectors labeled Tel 1 and
Tel 2. Each of these connectors can provide telephone service to multiple telephones, fax
machines, and analog modems.
The maximum number of telephone devices connected to each RJ-11 port is limited by the
total Ringing Load of the telephone devices that are connected. Many telephone devices are
marked with a Ringer Equivalent Number (REN). Each telephone port on the Gateway can
support up to a 5 REN load. The sum of the REN load on all of the telephone devices
attached to each port must not exceed 5 REN
Before you use the Gateway’s RJ-11 connectors to power the analog devices in your home
or office, disconnect the telephone lines from any other provider at the demarcation point. If
the incoming phone line is connected to another provider, such as an incumbent telephone
company, it can result in potentially harmful voltage to the analog telephone line.
Note: The customer or the customer's wire contractor is responsible for adhering to all local
codes for wiring.
To set up the ability to place calls using a regular analog telephone line (PSTN), perform the
following procedure.
1. Disconnect the phone lines from any other provider at the demarcation point, if appropriate.
2. Connect the RJ-11 cable on an analog device to the Tel 1 connector on the rear panel of
the Gateway.
3. Connect the RJ-11 cable on another analog device to the Tel 2 connector on the rear
panel of the Gateway.
