Jotron Analog to Digital Converter, JAD-801 and Jotron Digital to Analog Converter, JDA-801 are versatile tools for incorporating VoIP solutions in analog based receivers, transmitters and recorder systems. The units are 3U high and 12 units fits in a standard 19’ inch subrack. Both units use power over Ethernet (PoE) as the main power supply. They can also use one or two DC inputs (10-32V) as the main or backup supply.

Jotron Analog to Digital Converter
JAD-801 is a unit that converts up to 6 analog E&M inputs and switch these into 12 VoIP outputs. The format of the VoIP RTP streams complies with the RTP described in the current version of the ED-137 standard. The IP interface on the unit also complies with the SIP format described in the current version of ED-137 and fully support dynamic delay measurements used for voting as specified in version C of the standard. The primary use of the unit is to convert 6 analog receivers into 12 VoIP streams that can be interfaced to any ED-137B or C compliant VCS. 1 analog input can be converted to all 12 outputs, ie 12 users can listen to one receiver. It also allows 6 analog inputs to be converted to 2 VoIP outputs for each input. Usage is dynamically configurable by the remote control system or the VCS to fit the desired purpose.
Jotron Digital to Analog Converter
JDA-801 is a unit that converts up to 12 digital inputs into 6 analog outputs. The unit is fully compliant with the latest ED-137 standard with regards to SIP and RTP used to set up a radio connection. The unit supports PTT priority levels and/or mixing of input streams. The unit also fully supports dynamic delay measurements and delay compensation as specified in ED-137B/C. The primary use of the unit is to convert 6 analog transmitters into 12 VoIP input streams that can be interfaced to and ED137B or C compliant VCS. Any of the 12 digital inputs can be switched to any of the 6 analog outputs. Usage of the inputs and outputs are dynamically configurable from the remote control system or the VCS to fit the desired purpose.
