2. Fast track
FE1-FE1*ETH converter can combine and multiplex an Ethernet and an E1( user side) into
an E1 channel and transmit through E1 channel. The bit rate of E1 and Ethernet can be
adjusted provided the total bit rate does not exceed the E1 bit rate (1984Kbps).
E1-M is uplink channel; E1-S is downlink channel. The PCB for standalone and rack
version is same. Please indicate your requirement when order. The following are the operation
steps:

Connect with appropriate power supply as per back panel power indication; Power on, the
device will do self-detection, PWR,E1LOS-M,E1LOS-S indicators shall be on, rest shall be
off;

Connect Rx of E1-M with Tx of E1 channel on transmission equipment, Tx to Rx ;
E1LOS-M alarm indicator shall be off; if there is an error, you can press button to pinpoint
the error;

Based on client’s need, configure the time-slot of E1-S, connect E1 line to TX ,RX of E1-S,
the E1LOS-S indicator shall be off;

Based on Ethernet transmission requirement set up fixed timeslots (through 17~22th
dipswitch), connect Ethernet cable, the LINK indicator shall be on, SPD,F/D indicator
status shall be as per Ethernet working mode;

If you operate as per above steps, the device still does not work, please contact your
supplier or our technical staff for assistance.
