Important substation line cutover plan

Plan description:

The customer requires reliable transmission of business information of the power dispatching system, and provides two transmission routes for some important substations, and one system requires automatic switching protection. The following plan uses the main and standby routes provided by the customer to connect the ZMUX-122 E1 channel protection switching device output 1 channel, and then transmits the telephone, audio, RS232 serial port data and so on with the ZMUX-30 PCM multiplexing device.

1. Link requirements: Users need to provide any two E1 routes (E1 channel provided by SDH ring network, PDH optical transceiver, wireless spread spectrum, microwave etc.)

2.Recommended equipment: ZMUX-30 PCM multiplexing device, ZMUX-122 E1 channel protection switching device

Brief introduction of equipment

PCM multiplexing device ZMUX-30 is a PCM multiplexing device, which mainly completes multi-service access such as telephone, 4-wire audio (E&M), RS232, network, etc., and realizes multi-service signal point-to-point communication by multiplexing to one E1 transmission.

ZMUX-124 is 8 input and 4 output E1 protection switching equipment, ZMUX-124 is an E1 protection switching device, which can realize automatic switching function for two sets of E1 signals (lines) with different routes, and meet the 8 channel E1 line protection transmission 4 channel E1 signal.
