CPM5

Data Corruption on SDMA Flyby

Date Added: 5/30/2000

Description: The data of an SDMA write, which follows a SDMA flyby read in the local bus

may be corrupted.

Workaround: None

System Number: 1720

Fix Plan: Rev A

0K40A

CPM6

Erroneous Report of Overrun on FCC

Date Added: 5/30/2000

Description: Spurious overrun indications on the FCC may occur in the following cases:

1.

After a stop transmit command is issued.

2.

Following a CTS lost condition.

3.

Late collision under ethernet.

Workaround: None

System Number: 1746

Fix Plan: Rev A

0K40A

CPM7

Erroneous Report of Overrun With Fast Ethernet

Date Added: 5/30/2000

Description: If the CRS (carrier sense) signal is negated while fast ethernet frame is transmitted,

an overrun error may occur and the FCC may have to be reset.

Workaround: None

System Number: 1752

Fix Plan: Rev A

0K40A

CPM8

Error on Transmit On Demand Register

Date Added: 5/30/2000

Description: The TODR mechanism may freeze serial channels.

Workaround: Do not use TODR.

System Number: 2484

Fix Plan: Rev A

CPM9

Erroneous Reception of ATM Cell

Date Added: 5/30/2000

Description: Under certain conditions, an ATM receiver may receive cells of PHYs which were

not addressed for it. Details of the condition:

•

ATM receiver in UTOPIA slave mode.

•

FIFO full condition occurred (this happens only when the transmitter vio-

lates the UTOPIA standard requirements: transmits data without CLAV).

•

Transmitter changed selected PHY number.

•

FIFO full condition ended (CPM read some data from FIFO).

Workaround: Use different VPI/VCI for different PHYs or expect the cells to be discarded by

higher-level protocol software.
