SD 360F is a fully digital telephone system, with digital main units and digital telephones. The main unit adopts the most advanced PCM and TDM integration technology, and the main unit and the digital telephones are connected by 2-core non-polarized wiring (if the wiring is short-circuited, the system will automatically lock). The transmission mode is 2B + D, so the system can simultaneously transmit voice (VOICE) and data (DATA) on the 2-core wiring. It also uses the 2B + D architecture to provide two-way secretarial call (OHVA). Therefore, it is now possible for you to pre-set a digital network for your entire office and enjoy the various flexible services that digital systems can provide to meet the needs of the new era.
This manual describes the SD 360F all‑position telephone system, its main unit architecture, supported line types and capacity, and the various peripheral modules such as control units, service units and voice mail units.
It includes installation guidelines, wiring recommendations, power and grounding requirements, as well as fault‑diagnosis procedures and technical specifications of the hardware. This manual is written in Chinese.
