EFAS is an innovative transport system designed for the next generation of access networks commonly known as Metro Ethernet.
In the networks scenario EFAS can
be used for:
Both scenarios require a new class of access terminals with mapping capabilities of legacy data streams (mainly E1) into Ethernet carriers (GbE).
EFAS main features
The EFAS system subrack interconnects via backplane all the units:
All the units have a fixed position in the subrack and are in-field replaceable.
Subrack mechanical dimensions:
45 (H) x 440 (W) x 235 (D) mm
PDH E1 Tributary Card
Two optional tributary cards providing each one 16x E1 interfaces for a total of 32x E1 channels.
The L2 Switch card provides the grooming of Ethernet traffic via two GbE interfaces.
