off and on again. If this error persists, call for support.

Cannot set up E1channel
4.4.1
Same LAN domain
When two H0FL-ETHMUX V16’s are within the same Ethernet broadcast
domain, try following.
Check if the transmission network is on.
Check that the network will pass broadcast packets. For a network that
suppresses broadcast packets, as some of the wireless LAN bridges do, disable ARP
and manually setup local and remote MAC’s.
Check that there is no MAC address conflict on the LAN.
Check that the transmission network has enough bandwidth (more than 2.5Mbps
duplex).
4.4.2
Different LAN domain
When two H0FL-ETHMUX V16’s are in different Ethernet broadcast domains,
IP headers must be used, and packets will be routed by a gateway router, try
following.
Check if the default gateway IP is defined correctly.
Check if the local and remote IP is set correctly.
Check for any conflicts in IP or MAC addresses.
Make sure the transmission network has enough bandwidth.
4.5
Downstream reporting slips
Check if the downstream equipment has correct clock mode. At least one of
them must be clock master. Set the EthMux on master side to loop back timing.
If the downstream equipment on both sides is not synchronized, slips are not
avoidable.
At the transition time after power on or reapplying the E1signal, slips and errors
are acceptable. Such transition may take several minutes.
5.
Web Manager
Both Web Server and SNMP management are supported through anyone of two
user data ports of H0FL-EthMuxV16.
The management has three sections: Status, Configuration and System. User
name and password are required to enter the sections of Line Test Configuration and
system. Both the default user name and password are “admin”. Customers can
modify the user name and password in the System section.
