The ClearCom <strong> LQ-4W2 </strong> is a 2-Port Portable Unit for 4-wire Intercom over IP Interfacing. LQ®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® and Station-IC™ respectively, SIP/VoIP telephony to existing intercom systems, and enabling extra audio I/O for both HelixNet® and Eclipse® 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>
