619 GI - 4-way Audio Bridge (radio interconnect) - The primary function of the Audio Bridge is the combining and linking of up to 4 repeaters, links and other audio sources at remote sites. 619EI_GI.pdf

619 BR – an internal card for the 619EI that provides the user with the ability to pre-program up to six configurations of the 619EI with simple jumpers. Then via the simple grounding of any one of the six corresponding inputs, the 619EI will adopt the pre-programmed configuration. This is a simple and very effective means of dynamic reconfiguration of a radio network with the 619EI audio bridge.

619 TL & TLP- These two products offer a software variation to the powerful 619SRI product and provide users with a mobile tactical radio and audio dispatch product. Supplied with each 619TL is a Windows application and Operator’s headset that allows the operator to dynamically select, control or cross patch any of up to eight audio sources that are interfaced to the 4 Wire E & M ports of the 619TL or 619TLP. The 619TL has eight 4 Wire E & M ports for interfacing into any applicable audio or radio interface and the 619TLP offers six 4 Wire E & M ports with two analog telephone ports. 619TLbrochureUS.indd.pdf

IPR 100 - Voice over IP Adaptor. The IPR100 is a single channel analog audio to RoIP interface designed to provide Voice over IP extensions for analog radio equipment. The product supports a number of codecs with bandwidths of 13 – 64 kb/s. The IPR100 also supports a single RS232 port that is sent in parallel with the audio over the IP network – data speeds up to 38.4 kb/s may be supported with this serial interface over the IP. Each device enables an analog two-way radio to be remotely controlled over an IP link, either in a LAN or WAN environment. Working in pairs, two IPR100 Voice over IP adaptors can be used to create a back-to-back IP link between two radios. Alternatively, a pair of VOIP adaptors can also be used to provide remote control and monitoring of a single radio from an operator’s handset or console. IPR100-400.singles.pdf

IPR 400 - IPR400 Voice over IP Adaptor. The IPR400 4-Channel VoIP Adaptor for Radio provides Voice over IP extensions for analog radio systems and enables up to four two-way radios to be remotely controlled over an IP link, either in a LAN or a WAN environment. The IPR400 supports all of the feature set of the IPR100 with the addition powerful audio bridging and linking feature of the 4 Wire E & M audio ports. The IPR400 is housed in a compact 1U 19" enclosure and provides isolated 4-wire E&M interfaces, multi-casting, voice activity detection, voice compression, CTCSS, SELCAL and DTMF signaling, encryption and RS-232 data tunneling. In addition to these standard features, the IPR400 also provides site monitoring via SNMP and audio bridging (cross-banding). The audio bridging facility further enhances the product's value at repeater sites by providing the means to link together groups of radios, IP and VoIP channels, in various combinations.
