Local device can be connected by PC serial port through LNK-UP port to
realize network management. Address numbers of devices which are
concatenated on a PC serial port mustn't be repeated. Local concatenated
devices are maximum 15pcs.
Bits
Bit1 Ethernet port auto-negotiation configuration. Bit1 = OFF, Ethernet
auto-negotiation is enable.
Bit1 = ON, Ethernet auto-negotiation is disable. When the Ethernet
negotiation is disabled the port's MDI/MDIX function is disabled too, so
when connecting to switch the straight-through cable is needed and when
connecting to NIC and router the cross-over cable is needed.
4 bits
Bit2 Ethernet port's speed configuration when auto-negotiation is
disabled.
When Bit1 = ON, If Bit2 = OFF the Ethernet port's speed is 100M;
When Bit1 = OFF the Bit2 is invalid.
Bit3 Ethernet port's duplex mode configuration when auto-negotiation is
disabled.
When Bit1 = ON, If Bit3 = OFF the Ethernet port is on full-duplex mode;
When Bit1 = OFF the Bit3 is invalid.
Bit4 the configuration of ALS function.
Bit4 = OFF, ALS function is disable.
Bit4 = ON, ALS function is enable.
Bits
Bit1, Bit2 Optical port Auto-negotiation/Force configuration.
Bit1, Bit2 = OFF OFF, Optical port A and B can be chosen automatically.
Bit1, Bit2 = OFF ON, Optical B is chosen.
Bit1, Bit2 = ON X, Optical A is chosen.
Bit3 mask/unmask alarm configuration of idle E1 tributary.
4 bits
Bit3 = OFF, unmask alarm configuration of idle E1 tributary.
Bit3 = ON, mask alarm configuration of idle E1 tributary.
Bit4 Local/Remote E1 loop-back position configuration.
Bit4 = OFF, E1 remote loop-back.
Bit4 = ON, E1 local loop-back.
