time slot in a set.

TDM repeatedly transmits a fixed sequence of time slots over a single transmission channel. This technology basis enables TDM to assure the high quality of data circuit such as bandwidth, performance, reliability, and response time. TDM technology is suitable for real-time data transmission. Our network infrastructure consists of the fiber optic core networks with last mile copper wires service network connected to customers. Presently, Symphony offers TDM speed from 64 Kbps up to 2 Mbps with European-standard quality Modem featuring remote speed control adjustment from our operation center, without terminal equipment change at customer site. The modem interface supports variety connectors of V.35 and G.703 which facilitate a prompt service to customer. Our Power Alarm System provides monitoring function inspecting cable signal errors, unusual other defects caused by modem, etc. The alarm function pre-detects and alert our operation center to immediately resolve problem before customer informs an occurred errors. With these excellent features, TDM thus far gain customers’ trust and widely used e.g. financial industry, telecommunication industry, multinational companies, etc.
