VLAN. The port is re-configurred to allow public, external or managed
VLAN when the last switch-extension is removed.
The IP DSLAM can be connected to the ELN220 through the optical uplink
port of the ESN108 switch.
The Fast Ethernet (FE) to E1/T1 converter can be used to install EDA at
small remote sites through the E1 or T1 lines.
All the nodes are managed by the ECN as embedded nodes.
The 6 combinations of embedded nodes shown in the illustration can be
connected to any port of the ECN. The EXN104 converter on the remote
site will in some cases (2, 4 and 6) need a power node to supply the nec-
essary power. The power node EPN102 is illustrated below. When the
ESN108 switch is used remotely to aggregate the EXN104 converter (com-
bination 6) it can supply both the upstream and downstream converters
with power through the Ethernet cables. As indicated below the ESN108 is
connected to the uplink EXN104 through the electrical port 8, which must
be configured in the ESN108 in order to supply power through the uplink
port 8. The configuration is done through the command line interface of the
ESN108 or the ECN.
Note: Please note that the EDA 2.2 R1A release does not support daisy
chaining a mixture of ELN220 and ESN310.
