One device supports a maximum of two power supplies, two main controllers, 96 E1 ports, and two 2.5G optical ports
The PT-3000 intelligent digital distribution frame system adopts 3U high and standard 19 inch rack. one device supports full cross-connection for 96 E1 channels, and the system is equipped with 2 x 2.5G optical interfaces, supporting ring, link and star networking topologies.
The system can connect up to 10 devices via 2.5G optical transmission interfaces, achieving a maximum E1 cross-connect capacity of 1,008 lines.
The system is equipped with a Network Resource Management System (NMS). Through the NMS, users can easily configure cross-connections, set E1 port loopbacks, and read device configurations.
Supports 2M channel software switching function;
Supports real-time online LOS (Loss of Signal) and AIS (Alarm Indication Signal) alarm detection for 2M ports;
E1 support remote loopback, local loopback and bidirectional loopback settings;
Equipped with built-in multi-channel bit error rate tester (BERT) for simultaneous bit error testing of multiple channels;
The built-in BERT supports frame structure, test pattern, alarm insertion settings;
The test function supports statistics for errored seconds (ES), ES ratio, severely errored seconds (SES), SES ratio, alarm count, and alarm duration;
It supports online detection for 2M port frame structure;
It supports 2M port transmission delay testing;
It supports main control unit for 1+1 hot standby redundancy;
It supports optical interfaces for SNCP (Subnetwork Connection Protection) ring network protection;
It supports power-off bypass function: the service interface board can choose power-off bypass function board;
It has the function of automatic detection of device operation status, including all board status, temperature, etc.;
All boards support hot-swappable operation.
