Current E9-1-1 networks cannot accommodate non-audio based information beyond the subscriber telephone number and/or routing code data, which is limited to 8, 10, or 20 digits

Text and video data cannot be passed through the above limited design - no bandwidth to support

The data side of the E9-1-1 system could handle text data to a limited degree, but is not designed to do so interactively in real time (only TDD/TTY Baudot)

9-1-1 dialed calls from text or video devices cannot be delivered through the E9-1-1 systems
