Appendix A
The “ LAN port ” supports auto-negotiation or forced mode setting. If force mode setting the card, be sure to
properly configure the GSW port for the same forced mode. Additionally, the LAN port supports enabling flow
control, bandwidth control and can be made VLAN tag aware.
The “ Device ” tab has the major configuration options for the iMUX. It is most important that the E1 clocking be
configured properly. If this is a purely point-to-point application, we need one iMUX with internal clock and the
remote to follow. If the E1 travels over say an SDH network, then the clock will come from the network and both
iMUX ends should recover E1 clock.
T\If the VCAT configuration does not have all E1 checked, only those checked will be part of the VCAT group.
So, for example if you wanted to connect to a third party mux that only had 4 E1 members, we could turn off our 5
th
E1 here.
The SNMP Sa bits are required to support in-band management. By default they must all be checked ON. If
any are checked off and saved, communication to the remotely connected iMUX could be lost.
