5.2.1
The UTOPIA Receive Downstream Interface is identical to the UTOPIA Receive
Upstream Interface as described in
Standard Exceeding UTOPIA Feature
To support system architectures that require a bandwidth overprovisioning from the
backplane, the URXD can be operated up to 60 MHz which corresponds to a data rate
of 795 Mbit/s received from the backplane. This provides an overprovisioning factor of
1.32 to OC12 data rate on the line side as described in
5.2.2
The UTOPIA Transmit Upstream Interface is identical to the UTOPIA Transmit
Downstream Interface as described in
5.2.3
The UTOPIA Port/Address mapping (Backplane side) is identical to the UTOPIA Port/
Address Mapping as described in
5.2.4
The functional timing is compatible to ATMF UTOPIA Level 2 standard [4] and ATMF
UTOPIA Level 1 standard [3] respectively.
Remark 1
The ABM-3G UTOPIA Interfaces in master mode always introduce at least 1 idle clock
between transmission or reception of subsequent ATM cells.
Remark 2
The ABM-3G UTOPIA Interfaces in Level 1 Slave Mode do not support constant active
enable signals UTXENBi/URXENBi (i = {D(Downstream); U(Upstream)}).
The enable signals must be deasserted with each cell cycle.
5.2.5
The UTOPIA Polling scheme (Backplane side) is identical to the UTOPIA Polling scheme
as described in
