3.3.2 Connecting the Ethernet Cable
The MX100E has the dual-network-interface redundancy function. When one of the network interfaces is
disconnected or does not work well, traffic services can be switched seamlessly to the other one.
The MX100E has two service interfaces, namely ETH1 and ETH2 for your choice. These two interfaces
need to be connected to the same hub, LAN, or WAN. Only one of them works at a time. After Ethernet
cables are inserted, check the indicator state of the interface that is connected first. If the indicator is long
green or blinking green, it indicates that the connection is established properly.
The MX100E has two auxiliary interfaces, namely AUX1 and AUX2. In most cases, no connection is
required for auxiliary interfaces.
3.3.3 Connecting the T1/E1 Cable
MX100E offers RJ45 jack as T1/E1 connector for making ISDN connection with PBX or PSTN.
Please identify the connector type and interface impedance of the other side equipment before making
T1/E1 connection.
If the other side equipment offers same RJ45 jack, use CAT5 cable with RJ45 plugs on both side to make
T1/E1 cable connection. Be sure to mach TX and PX pair according to the PIN specification when
making the CAT5 cable.
If the other side equipment offers separate TX/RX coax connectors for T1/E1connection, use
RJ45-Balum-Coax cable sets and follow the figure to make the connection.
