IDM NTD421 (DT) Elevator Five-party Intercom Telephone Optical Terminal
Due to the different working principles between five-party intercom telephones and standard telephones, ordinary telephone optical terminals cannot be used. Raytrans' dedicated five-party intercom interface card is compatible with the signaling of five-party intercom units, enabling five-party communication between the central office and the machine room, car, car top, and pit. Five-party intercom optical terminals are available in 2-channel IDM NT202(DT), 4-channel IDM NT104(DT), 8-channel IDM ENT448(DT), 30-channel IDM 30EN(DT), and other models, meeting the signal transmission requirements from elevator group machine rooms to the central monitoring room of various capacities, and also suitable for fiber access transmission in scenarios such as monitoring room relocation or consolidation.

IDM NTD421 (DT) Elevator Five-party Intercom Optical Terminal Overview
With the expansion of modern residential communities, the distance between the central monitoring room host duty room at the elevator central office and the elevator machine room may exceed the transmission distance of five-party intercom twisted pair cables. As a result, the communication mode between the central office and the elevator machine room has undergone various changes. One approach is to use GSM transmission, which is constrained by GSM's billing model and is not economically efficient.
Beijing Raytrans Digital Technology Co., Ltd. provides two solutions based on fiber optic and IP communication networks respectively, meeting user requirements in different scenarios.
