Specifications

Brief Introduction
    PT-50T 5256 PCM equipment adopts 9U(with fan) or 5U (without fan) high standard 19" rack. It supports multiple analog and data access, and fiber/electronic integration. The maximum 64Kbps access capacity of PT-50T 5256 PCM equipment is 240, and the maximum E1 access capacity is 240 as well.
    PT-50T 5256 PCM equipment can connectwith other transmission equipment through its optical interface or standard E1interface. It can realize point to point communication and point tomulti-points communications by E1 or optical interface; and it can execute D/I(drop/inset) function through its own 240 E1 cross connection matrix; and it can have online test functions including remote channel circuit test and 2 wire subscriber line tests.
    PT-50T 5256 PCM equipment is provided with a powerful NMS system, by which the operating status of the network can be monitored in real time and the functions including malfunction locating, timeslot reassignment and online test can be performed easily. Through the NMS platform, the functions of third party call for any time slot, sending signaling signal and audio signal, 64K error code test for E1 channel and online monitoring any channel will be realized.

Main Features
* System capacity
   The maximum system capacity of 64Kbps interfaces are 240, and the maximum access capacity of E1 interface is also 240.
* Abundant  Access Interfaces
