Multi-service interface card

The M30/M32 multi-service interface card over 1 channel E1 or 1 channel fiber to transmit the telephone, audio, data, and images etc and realize the service signal point-to-point communication function.

The M30 card transmission link is an E1 electrical port, and the M32 card transmission link is a fiber interface.

The M30/M32 cards are designed as module, with 10 service interface. They can be assembled according to the customer's requirements. The device is easy to expand, and can effectively support the user's current business needs and future business expansion, providing customers with an economical and efficient solution.

The M30/M32 card has 10 RJ45 ports to complete 1~10 channels of general service access. One M30/M32 card can complete a remote service signal integrated access, corresponding to a remote network communication. Each M30/M32 board is independent and the faults do not affect each other
