The ClearCom <strong> LQ-R2W4 </strong> is a 4-Port 1RU, 2-Wire LQ Series IP Intercom System Interface. LQ&reg; Series devices provide intercom connectivity for linking multiple systems together over IP networks, extending intercom channels to remote locations, adding mobile and virtual clients through Agent-IC&reg; and Station-IC&trade; respectively, SIP/VoIP telephony to existing intercom systems, and enabling extra audio I/O for both HelixNet&reg; and Eclipse&reg;HX systems. </p><p>LQ IP interfaces enable connection of 2-wire partyline, 4-wire or 4-wire with GPIO audio over LAN, WAN or Internet IP infrastructures. The LQ Series consists of compact LQ boxes and rack-mounted LQ-R panels, available in 2-, 4- or 8-port versions. The partyline ports are Clear-Com and RTS compatible. Two standalone partyline intercom circuits can easily be constructed by connecting two partyline ports. The 4-wire ports can interconnect with devices, such as analog ports of any matrix intercom system, analog telephone circuits, two-way radio gateways and audio consoles. A maximum of six LQ Series IP devices can be linked together in any 2-, 4-wire or 4-wire with GPIO combination. </p><p>LQ Series devices can connect to Eclipse HX frames via the IVC-32-HX Interface Card over LAN, WAN and Internet IP networks using the G.722 codec. Each LQ Series device can connect to up to eight IVC-32-HX ports from different IVC-32-HX cards or Eclipse HX frames. This allows you to remotely connect any LQ Series device directly into an Eclipse HX frame across any distance. LQ Series devices can link with HelixNet main stations using the HLI-ET2 module over LAN and WAN IP networks. This allows the main station to use the LQ ports as extra audio input and output to the HelixNet system. Linking to an LQ device also allows HelixNet users add Agent-IC clients and SIP or VoIP telephony connections to the HelixNet channels.</p><p><b>Please Note!</b> This item is just one component of a larger system.
