VoIP - IP Telephony White Papers
Extended Loops for Distant Phones and Fax Machines, Higher Ringing Voltage and Loop Current
Overview Enterprises are turning to Voice-over-IP (VoIP) and IP telephony solutions for voice communications in corporate and branches so that they can reap the benefits of converged networks and feature-rich IP-based telephone systems. While enterprises are making the migration to IP telephony, on many occasions legacy analog phones, modems, and fax machines continue to be important and vital components in the network. Applications exist that require extended loops between the analog phones and the gateway. Examples include phones in multi-story buildings, on large campuses, in large railroad yards, in large industrial plants, and in remote locations such as utilities applications. Other applications require accommodations for specialty phones, including elevator phones, emergency kiosk phones, and neon-lamp phones.
