Description of the EAN
28 1553-CNH 160 0787 Uen PA2 2005-09-23
• ESN108 – 8 port switch
• ELN220 – 24 optical switch
• ESN310 – 24 port switch
• ECN320/ESN310
• ECN330 switch
• EXN104 – FE to E1/T1 converter
• EDN312 and EDN110 – IP DSLAMS with 12 and 10 lines
• EPN102 – The Ethernet Power Node used together with the remote
EXN104
An access domain consist of more EANs as well as stand-alone IP
DSLAMs connected to for example an ESN310 switch.
The embedded nodes of the EAN are not shown, when the network topolgy
or inventory is viewed in the HP OpenView NNM or the PEM application
Network Configuration Manager (NCM). For example viewing the network
shown in
Figure 11 on page 29, will show only four elements: one EDN110,
one ESN310 and two EANs. Alarms coming from an embedded node will
be seen as if they come from the EAN (though identifying the embedded
node).
Viewing an EAN in the Status Manager in PEM will show all the embedded
nodes: ECN, a number of ESN108 and a number of IP DSLAMs and so on.
The status of each embedded node can be inspected, including single
ADSL lines status and properties.
The EDA System in
Figure 11 on page 29 shows two EANs and a stand-
alone solution based on the ESN310 switch. The EAN to the right shows a
combination of the ECN and the 8-port switch ESN108. Each ESN108 has
up to 8 IP DSLAMs, as for example the EDN312 IP DSLAMs. The EAN to
the left shows the IP DSLAMs connected directly to the ECN.
The topology is discussed in more details in the sections below.
