It is needed to set up the Ethernet port working status of connected switches, hubs, or NICs
according to following table:
Port of Remote-site Equipment
Switch Setup of Local
Equipment
Actual Working
Mode
10/100M Auto-negotiation
Any
10M Full Duplex
Fixed 10M Half duplex
OFF (default)
10M Half Duplex
Fixed 10M Full Duplex
ON
10M Full Duplex
10M Duplex Auto-negotiation
Any
10M Full Duplex
Because the Ethernet port of the local equipment is set as on 10M full duplex auto-negotiation
mode, it cannot be connected with the port of fixed 100M rate.

bit Please keep factory default status OFF, when the equipment is working properly.

rd
bit Fractional/transparent selection switch of E1 interface.
On = E 1 fractional mode. Transmission bit rate is N*64Kbps, N=1~31
OFF= E1 transparent mode, also called “un-fractional mode”, and the transmission bit rate
is 2048Kbps (Default).
At default status, the equipment is working on E1 transparent mode, and the dip-switch SW1 is
thoroughly disabled. Only when this bit is set up to fractional E1 mode, the 8 bits of dip-switch
SW1 is workable.

th
bit Remote loop-back control Switch of E1 interface, for engineers to test link condition.
ON= in test status Remote-site Loop back—E1 input signals of the remote-site equipment
is not processed internally, but directly output from the output port.
