Revcord relies on Control Data, either through a tower and a Control Channel Receiver, or through an ATIA data feed for when multiple sites are involved. Revcord is dependent on having analog channel audio feeds. With the advent of the VPM interface of the MCC7500, this cost has come way down compared to buying a radio resource for each analog channel. This is by far the most economical solution in the marketplace today.
We have opened up IQ3 and MD for use with Bluetooth devices for both input and audio use. IQ3 and MD have the ability to take inputs from a user’s Bluetooth mouse, keyboard, speakerphone, headset, and even microphone. MD features support for many Bluetooth medical devices such as blood pressure cuffs, pulse oximeters, and more.
Revcord IQ3 and MD both allow for the recording and streaming by a vast amount of IP Cameras. We currently support any camera that is able to stream in the RTSP Protocol. You can easily switch between your onboard device camera and a stationary IP in mid-event!
Referring to the Text To 9-1-1 diagram, all data ends up in a TCC or Text Control Center. Currently there are only two companies which can accept and send data to and from the TCC. The first is Intrado now known as West and the second is TCS which is now known as Comtech Telecommunications Corp. The two TCC providers provide this service to many CPEs as well as their own CPEs.
There are currently three methodologies for getting Text To 9-1-1:
Method 1 (TTY/Baudot)
Recording is currently limited to TeleTYpewriter (TTY) or Telephone Device for the Deaf (TDD) tones (Baudot) that are sent over standard CMA trunks. The downside is that each text ties up one PSAP trunk.
Method 2 (The Web Solution)
On the way to NG9-1-1 there will be “baby steps” for some of the technologies. For a Transitional PSAP Text to 9-1-1 can be received. Web access via secure Internet or IP network is required. Normally a dedicated browser and monitor would be constantly monitored for text messages. ALI is displayed as the texter’s phone number and location currently is the centroid of the cell sector. Recording is done via screen recordings or in some cases a screen scrape of the data.
Method 3 (MSRP – Full Integration Into The CPE)
This is the “real deal”, sometimes referred to as i3. Everything is IP and all communications, including text are SIP/RTP. This is very complex technically.
Revcord has completed testing of i3 NG9-1-1 Text to 9-1-1. In brief, the Text Control Center sends text messages using MSRP (Message Session Relay Protocol) via SIP – much like Instant Messages – to the NG9-1-1 ESInet. Text, like all media is sent via RTP using Real Time Text/RFC4103. Yes, it is highly technical and Revcord does record it TODAY! If the standards that are set in the i3 specification revolving around SIPREC are being followed by the CPE, Revcord has you covered. Revcord provides this service at the position level and each position is treated as a TT9-1-1 channel.
