IDM DTWF-2 Elevator Five-party Intercom IP Gateway
When there is no fiber connection between the central monitoring room and the elevator machine room, but an IP connection channel is available, a VoIP-like telephony mode can be adopted without requiring a SIP server. Instead, an end-to-end IP hotline connection is used, in which case the IDM DTWF-2 Elevator Five-party Intercom Gateway can be deployed. If the IP network is not a private network, VPN virtual private network technology must be provided. The IDM DTWF-2 provides conversion of 2 elevator intercom interfaces to the IP transport network.

Overview
As modern residential communities continue to expand, the distance between the central monitoring room at the elevator management end and the elevator machine room may exceed the transmission distance of five-party intercom twisted-pair cabling. As a result, the communication mode between the management end and the elevator machine room has undergone multiple changes. One approach is to use GSM transmission, but this method is constrained by GSM billing models and is not economically viable.
Beijing Raytrans Digital Technology Co., Ltd. provides two solutions based on fiber optic and IP communication networks respectively, meeting the needs of users in different scenarios.
