When there is no voice activities on the radio side voice signal at the telephone side will be transmitted Therefore both sides will have to adapt to this talking method in order to conduct a normal conversation 8 Application Examples Example 1 Linking up two MOTO GM300 Radio terminals in peer to peer mode with two RoIP302 RoIP302G The network access method is ADSL Operating procedures 1 Connect the PTT Interface of the radio terminal GM300 with the PTT Interface Cable as shown in the diagram below Connect the RJ 11 plug of the PTT Interface Cable to PTT1 port of the RoIP302 2K TEN opr ao 208 ___ PT Tout GM300 sat GND PTT Interface with PTT Radio Terminal interface ne MOTO GM300 Cable 2 Connect the RoIP302 LAN port to an Ethernet port of the ADSL Router 3 Assign a fixed IP to the RoIP302 LAN port This fixed IP must be in the same segment as the LAN port of the ADSL Router For example if the LAN of the ADSL Router has an IP 192 168 1 1 then the LAN port RoIP302 could be set to 192 168 1 101 4 Configure the DMZ mode of the ADSL Router to fixed IP assigned to the RoIP302 LAN port For DMZ configuration please refer to the User Manual of the Router 5 Login to the RoIP Webpage and program the Network Settings as shown below Please note that the DNS addresses should be programmed as provided by from your local ISP www dbltek com ROIP302 Series User menu Network Configuration LAN Por2. Please note that only one one way voice transmission is allowed at all time When a voice signal is transmitted from a RoIP302 RoIP302M will re transmit the signal to all other clients in the same group TT the voice signal is coming from a PTT port radio terminal of the RoIP302M the RoIP302M will re transmit the voice signal to all other PTT ports and SIP clients that are in the same group For example if Channel 802 talks Channel 701 803 and 804 can hear If Channel 701 talks Channel 802 803 and 804 can hear www dbltek com ROIP302 Series User menu Please note that when more channels are used the higher bandwidth is required and the poor the performance of the system is It is recommended that the user needs to insure sufficient bandwidth is available and the network connection is stable before implementing a large network In general intranet network is preferred in this case Group 1 RolP302 7 ane ed Are ri et Bn 7 B RolP302 N ROIP302 3 3 Application Examples Application example 1 Link up radio network between two locations Using two RoIP302Gs to link up three radio channels in two different locations www dbltek com ROIP302 Series User menu Internet Location A Location B Application example 2 Link up radio network at multiple locations As shown in the application diagram above four locations can be linked up via one The RoIP302GM has a built in SIP server and the group By
