Installing the Telephone for VoIP
The SBV6120 allows you to use your cable Internet connection for VoIP telephone service. You
can connect up to two standard telephone lines on the SBV6120.
Before connecting the SBV6120 to your telephone line, contact your cable service provider. DO
NOT connect the telephone cable from the TEL port on the SBV6120 to a traditional telephone
wall jack; only connect it to a telephone.
CAUTION: To reduce the risk of fire, use only No. 26 or larger UL Listed or CSA Certified Telecommunication Line Cord or
national equivalent to connect a telephone line to your SBV6120.
Use only a standard telephone. In many businesses, digital phones that connect to a private branch
exchange (PBX) do not operate with the SBV6120.
To connect a telephone to the SBV6120, do the following:
1. For a single or two-line telephone, plug the telephone cable into telephone and the TEL 1/2
port on the SBV6120.
Note: You can only use the TEL 1/2 port to connect a two-line telephone. Also, pulse-dial devices are not
supported.
2. For a second single-line telephone, fax machine, or other device, plug the device cable into
the device and the TEL 2 port on the SBV6120.
3. Connect an Ethernet cable to the Ethernet ports on the computer and SBV6120.
