The VOIPs integrate seamlessly with existing VoIP phone systems, and support standard VoIP protocols. For sites without existing VoIP systems, two VOIPs can be used in conjunction to send emergency calls over the IP network and then remotely “jump off” onto an existing PBX or PSTN phone network.

I. INTRODUCTION 1. In this proceeding, we seek to make it possible for customers to download data from the Internet more quickly. Our proposal, if adopted, could somewhat improve the transmission rates experienced by persons using high speed digital information products, such as 56 kilobits per second (kbps) modems, to download data from the Internet. Currently, our rules limiting the amount of signal power that can be transmitted over telephone lines prohibit such products from operating at their full potential. We believe these signal power limitations can be relaxed without causing interference or other technical problems. Therefore, we propose to relax the signal power limitations contained in Part 68 of our rules and explore the benefits and harms, if any, that may result from this change. This change would allow Pulse Code Modulation (PCM) modems, which are used by Internet Service Providers (ISPs) and other online information service providers to transmit data to consumers, to operate at higher signal powers. This modification will allow ISPs and other online information service providers to transmit data at moderately higher speeds to end-users.
