Trouble: LINK light OFF
Check point:
This fault is basically due to the error in making network (crossover or
straight-through) cable. Please check if the equipment I require crossover cable or
straight-through cable you are connecting to. VCL-4 Ethernet over E1 is
self-adaptive to crossover or straight-through cable.
5.
Trouble:
LINK light in normal state, but data PING fails
Check point:
1. Check whether the state of the equipment Ethernet is in accordance with that
of the opposite-end Ethernet; If not then, cancel the self-adaptive state of
Ethernet Interface and change compulsorily to configure speed and duplex
so as to be in accordance with the other end.
2. Check whether the equipment E1 port or E1 transmission channel is under
loop-back or other test conditions, if any, then cancel it.
3. Check whether the time slot configuration of the local equipment is in
accordance with the remote one. If not then, configure it to be in accordance.
6.
Trouble:
Data succeed in PING, but with frame loss
Check point:
This fault may be due to the following reasons:
1. Incompatible configuration of E1 port impedance.
2. Incomplete physical connection of E1 port, e.g. only one pole connected at
receiving end.
3. Wrong configuration of clock, change the clock to master clock.
7.
Trouble:
The communication is normal prior to configure port mask, but blocked after
port
mask configuration.
Check point:
Ensure whether the remote equipment also configured port mask,
whether the port mask configuration at two ends is in accordance; after port mask
configuration, only Ethernet of same port number can perform communications. Check
whether VLAN switch set to OFF (shared link mode is ON) the equipment connected
to Ethernet interface, if any, Toggle the VLAN switch to ON (set the equipment for
discrete link mode).
