Figure 36. Example of interface converter
All devices should connect automatically if all connections are done correctly. Use the terminal connector
for configuration changes and to check the status of local or remote devices.
If backup facilities are desired, Optic Model topology must be used.
Refer to chapter 3 for additional information about configuration using the terminal port. SNMP
management is detailed on chapter 13.2.
15.10. Transparent Interface Converter Topology
This topology does not have remote management (in band), so each device must be locally configured.
Only the aggregate interfaces are disabled. All tributaries are automatically disabled.
This topology is a variant of the interface converter topology described above. Similar precautions to those
of item 15.9 must be taken, except for the fact that there is no data mixer in the optic interface.
Interoperability with devices from other manufacturers is thus assured.
15.11. Regenerator Topology
This topology does not have remote management (in band), so each device must be locally configured.
Only the aggregate interfaces are disabled. All tributaries are automatically disabled.
Figure 37. Example of Regenerator topology
Connect power supply, aggregates and Ethernet cable if necessary. When connecting the aggregate, be
careful to connect TX to RX when using two fibers and 1310 nm to 1550 nm cards when using monofiber.
All devices should connect automatically if all connections are done correctly. Use the terminal connector
for configuration changes and to check the status of local or remote devices.
Refer to chapter 3 for additional information about configuration using the terminal port. SNMP
management is detailed on chapter 13.2.
15.12. Ethernet 10/100BaseT Remote Bridge
Operation of the bridge is independent of the topology adopted, provided it does not ignore the tributaries.
Therefore the bridge configuration can be made once all devices are connected and running.
Define if will be necessary the sequencing of packets transferred by WAN. Check if will be used only one
(or a few) TCP connections amongst the locations. Check if there is disparity in the paths used by E1
tributaries applied in the inverse mux. In all cases, it is recommended the use of bridge_HW2 to obtain
better performance.
The Ethernet interface may be configured to half duplex or full duplex, as well as if back pressure flow
control (half duplex) or flow control (full duplex) is enabled.
For trunking, set inverse multiplexing either directed to the aggregate or to the 2M (6.703) tributaries (e.g.
for radio connections). Please note that although a DM4E1 may use an E3 aggregate card and the bridge
may run under Nx2M rates, there will only four available interfaces when trunking is directed to the 2M
(G.703) tributaries.
