Cross-multiplex card

The M30ETH cross-multiplexing card is inserted into service board slot of the ZMUX-3300 platform. It mainly completes 1~4 channel E1 signals and 1~4 channel Ethernet signal access, and realizes 4channel E1 or 4channel Ethernet time slots cross-connect. It supports E1 line protection switching function,optional 1+1 or N:M multi protection mode

The M30ETH card has one DB37 connector to complete 1~4 channel E1 signals access, with 4 channel E1 non-blocking arbitrary time slot cross-connect function and E1 line protection switching function.

The M30ETH card also has four RJ45 ports, which complete 1~4channel Ethernet signal access and cross-multiplex to 1~4channel E1 transmission. Each Ethernet is physically isolated and works independently, and bandwidth can be allocated arbitrarily.
