description:
Based on the existing E1 link, the ZMUX-3300 and ZMUX-30 PCM are used in conjunction with the application. The substation user remote terminal equipment (RTU), monitoring data, voice telephone and computer network services are accessed through the PCM, multiplexed onto the E1 channel, and transmitted to the dispatch center.
This solution has good scalability and can expand various services according to user demands. It supports multiple function applications, such as multi-E1 access, intelligent increase or decrease of Ethernet bandwidth, time slot crossing,dual transmission channel 1+1 hot backup, etc.
1.Link requirement: the local central office station and the remote station over E1
2. User requirement: the central office station provides 4 telephones, 4 RS232, 1 Ethernet services to each of the 8 remote station.
3. Recommended equipment: the local central station is equipped with ZMUX-3300, and the remote station is equipped with ZMUX-30.
