IWE8, V3.4
PXB 4219E, PXB 4220E, PXB 4221E
Functional Description
3
Functional Description
All functional parts of the device are implemented in hardware. Configuration of the
functional blocks has to be done by software via the micro controller interface.
The IWE8 provides two independent data paths for upstream, towards the ATM network,
and downstream, from the ATM network, direction. For dedicated functional tests
loopbacks between both are available.
Each of the 8 ports connected to the data path works independent from the others. It can
be switched to ATM or AAL mode and provides access to the E1/T1 Framer at different
framer interface protocols.
