SBC To File Tariff With FCC For New VoIP Service

SBC Communications Inc. is planning to introduce True IP to PSTN (TIPToP) service in the coming week by filing a tariff with the Federal Communications Commission (FCC).

TIPToP service is a time division multiplexed (TDM) telecommunications service featuring switched circuit interfaces specifically designed for use by a VoIP provider to connect traffic from its IP end users to end users of the circuit-switched network.

According to SBC officials, TIPToP service is not a mandatory offering but voluntary. VoIP providers who choose not to purchase TIPToP service may use other services, "to the extent permitted by existing tariffs and prevailing law, to connect traffic from their customers to the circuit-switched network," according to SBC.

According to reports in the Wall Street Journal, SBC's plan will involve an increase in fees normally paid for interconnection services--a rate increase that has reportedly drawn immediate scrutiny from the FCC.

In response, SBC stated there is no fee increase and that it could not release pricing details until after the tariff was filed, noting that "some VoIP providers may find it more economical than what they are purchasing now."
