Clear-Com LQ-2W2 2-wire intercom IP network interface

LQ IP interfaces are compact boxes that enable connection of 2-wire partyline and 4-wire audio devices over LAN, WAN or Internet IP infrastructures. This model is the 2-wire (LQ-2W2) option. This two channel Partyline IP communications interface is used for extending Partyline audio communications and call signaling to remote sites over IP networks (LAN, WAN, Internet).

This design supports two channels of audio and signaling which can be routed to up to five other LQ units, You can link over IP into Eclipse frames via E-IPA-XX or IVC-32-HX and HelixNet via a HLI-ET2 module . Licensable hosting of up to 8 Agent-IC clients and 8 lines of IP telephony (SIP) per unit.

This LQ device has two Neutrik etherCON series lockable RJ45 chassis connectors for network connectivity. The LQ-2W2 has two 3-pin XLR-F audio port connectors for partyline audio. The LQ-2W2 can power the partyline, allowing the user to connect a beltpack without the need of a power supply to locally power the line. A total of 5 beltpacks can be locally powered or one beltpack can be powered using PoE.
