2.2 ESN108

The ESN108 is a small Fast Ethernet

Layer-2 aggregation switch developed for

the EDA solution. It is used for

concentrating the data traffic upwards in

the network.

The ESN108 switch is equipped with 8

electrical 100Mbps Fast Ethernet ports,

and two redundant Small Form-factor

Pluggable (SFP) optical modules with 100/1000 Mbps (Single Mode Fiber,

Dual Fiber) intended to be used for the uplink. It is also possible to use one

of the electrical ports as an uplink.

The switch can supply Power over Ethernet to EDA nodes, which are

connected to the electrical ports.

The ESN108 can be mounted on rods or U-shaped back mount frames.

The switch can be managed through any Ethernet port, using PEM and the

Local Craft Tool (LCT).

2.3 EXN104

The EXN104 is a small managed Fast

Ethernet to E1 or T1 converter

developed for EDA rollout where no

Ethernet uplink is available. Up to four

E1 or T1 lines can be used in parallel.

This is a cost-effective solution for

transporting the Ethernet traffic through vacant E1 lines using the EXN104.
