PT-50T 1080 PCM Equipment
The PT-50T 1080 PCM equipment is a new-generation PCM device developed and produced with fully domestic components and completely independent and controllable technology.
The PT-50T 1080 equipment provides standard E1 electrical port access, and the branch side supports PCM access including automatic telephony, magneto telephony, low-speed data, 2/4-wire EM audio, K interface, C37.94, 64K synchronous G703, N*64K Ethernet, etc.
It can meet the access requirements for different bandwidths and various service interface types of private network users such as power distribution network intellectualization, industrial automation, transportation, railway and air traffic control, as well as major operator customers.
The equipment's network management system supports domestic independent innovation platforms, adopts front-side card insertion and front-side cable outgoing for services, and is equipped with a built-in intelligent fan unit.
