M30T/M32T_ZMUX-3300 Voice interface card

M30T

Voice interface card

    The M30T/M32T voice interface card can be used to insert any common service board slot of the ZMUX-3300 platform, which over E1 or fiber transmit to realize telephone service access.

Product description

The M30T card transmission link is an E1 electrical port, and the M32T board transmission link is a fiber interface.

The M30T/M32T card are modular design and offer 30 voice module slots to fit the voice module exactly as required.

The M30T/M32T card has one DB62 interface to complete 1~30 telephone signal access. One M30T/M32T card can complete a remote 1~ 30 voice signal access, corresponding to a remote network communication. Multiple M30T card can also be aggregated into one optical signal to complete large-capacity voice signal transmission through optical fibers. Each M30T/M32T board is independent of each other, and the faults do not affect each other.
