Description of the power dispatch automation communication network program:
Conditional: SDH transmission network exists between the central office station and the 10 remote station, and an E1/2M link is provided through by SDH ring network.
User requirements: Each remote station transmits telephone, telecontrol data, and Ethernet to the central office.
The data telecontrol signal is transmitted through RS232, and the analog telecontrol signal is transmitted through the 4W EM.
Recommended equipment: central office: ZMUX-3300 centralized PCM multiplexing equipment
remote: ZMUX-30 PCM Multiplexer
Solution Description: Based on the existing E1/2M link conditions, the ZMUX-3300 device and the ZMUX-30 device are used to multiplex the telephone, telecontrol data, and Ethernet services to the E1 channel, and then extend the remote station. The PCM device enables central monitoring. It can be realized at any time by adding a card to expand service in the future
Equipment features:
The central station is a centralized PCM device of the ZMUX-3300, which can synthesize E1 in 1~14 directions into one frame.
The remote station is a ZMUX-30 PCM multiplexing device, which is flexible and compact.
1. Easy installation and maintenance;
2. Multi-service, large-capacity hybrid access;
3. Convenient expansion (adding card can be realized);
4. All PCM can achieve centralized monitoring, easy to maintain;
5. The central station uses digital cross-card to reduce the cost of networking;
6.Cheap price and good performance
