VoiceFinder AP-LMR2000 LMR(Land-to-Mobile Radio) gateway is a new cutting edge LMR gateway supporting maximum 4 ports of radio interface with two(2) module slots. Radio and LAN interface of AP-LMR2000 provide an optimized call scenario for RoIP (radio over IP) service when it interoperates with conventional radio device. Compact cost effective design and system architecture of AP-LMR2000 provides customer satisfaction in high quality, performance and system reliance. This product uses the state-of-art technology voice compressed algorithm and unique QoS algorithm of AddPac to maintain the maximum Radio over IP voice quality under fast internet line and slow internet line as well. VoiceFinder AP-LMR2000 LMR gateway provides high-performance radio over IP(RoIP) solution for military, and police as well as fire station and construction area.
Module Type Radio Interface Support
LMR(Land-to-Mobile Radio) gateway combining IP-PBX, PTT Server, IP Phones for PTT service is now suggesting a new model for a main RoIP(Radio over IP) communication solution.In order to be a part of advanced RoIP communications naturally in the future, making an excellent choice of choosing LMR gateway is essential. AP-LMR2000 is a mid-range LMR gateway providing two(2) radio interface module slots. It is suitable for general enterprises, small and public offices. It has functions as a LMR gateway which interoperates with radio device between IP network and radio network. Especially AP-LMR2000 provides an optimal solution of RoIP communications in telephony environments that using PTT Server, PTT IP phones and IP-PBX to get connect with a head office.
Powerful Network·CPU Interface
AP-LMR2000 LMR Gateway is designed to provide high-performance service as a media gateway. It provides LEDs on the front panel indicating operational status, line status, and LAN Interface status of gateway. Two of 10/100Mbps fast Ethernet port and RS232C console interface are the base for delivering various network services such as LAN-to-LAN routing, Bridge and NAT/PAT service etc
High quality of communication and additional services
