4 Configuring Ethernet Services
The completely isolated data services of two users at a station must be transported to another
station.
4.4.2 Signal Flow and Timeslot Allocation
Ethernet services are received from an external port, encapsulated through an internal port, and
mapped to the SDH network for transparent transmission. In this way, the node communicates
with a remote node.
4.4.3 Configuration Process
The Ethernet transparent transmission boards support only EPL services. The EPL are already
created by default and hence you need not configure the Ethernet transparent transmission boards
on the U2000.

The two branches of user A that are located at NE1 and NE3 need to communicate with
each other over Ethernet. A 10 Mbit/s bandwidth is required.
The two branches of user B that are located at NE1 and NE3 need to communicate with
each other over Ethernet. A 20 Mbit/s bandwidth is required.
The services of user A must be isolated from the services of user B.
The Ethernet equipment of user A and user B provides 100 Mbit/s Ethernet ports of which
the working mode is auto-negotiation, and does not support VLANs.
