CPM117

False Address Compression

Date Added: 11/05/2004

Description: If there are active AAL0 channels and a CRC-10 error has been received, VP-level

address compression might have false results, which could lead to one of the following:

•

Wrong calculation of a VP pointer address

•

Cells might be falsely discarded as misinserted cells

•

Misidentification of misinserted cells (in CUAB mode) This is a statistical error, which is

conditional on the reception of AAL0 cells with a CRC-10 error. The probability of false

address compression is directly correlated with higher CPM bit rate and longer system bus

latency.

While the false address compression is possible only if there are active AAL0 channels, it may

have an impact on all AAL types. However, it cannot occur unless AAL0 cells with CRC-10 error

have been received beforehand.

Workaround: Use the microcode patch supplied by Freescale.

Aborted HDLC Frame Followed by a Good Frame

Date Added: 7/11/2004

Description: When an aborted HDLC frame is followed by a good frame, the receive data buffer

may contain the data of the aborted frame followed by the data of the good frame.

Workaround: Use the microcode patch provided by Freescale.

Ethernet Collision Occurs on the Line 125 Clocks after TX_EN Assertion

Date Added: 7/11/2004

Description: When an ethernet collision occurs on the line 125 clocks after TX_EN assertion,

late collision will be reported even though this is only 63 bytes into the frame instead of 64. When

a collision occurs 124 cycles after TX_EN assertion, no event is reported, the TxBD is not closed,

and transmission halts. Retransmission behavior is correct for collisions occurring between asser-

tion of TX_EN and 123 clocks.

Workaround: Use the microcode patch provided by Freescale.

SS7_OPT[FISU_PAD] parameter has no effect on the number of flags between FISUs

Date Added: 12/22/2004

Description: The SS7_OPT[FISU_PAD] parameter has no effect on the number of flags be-

tween FISUs. Regardless of the value of this field, one flag will be present between back-to-back

FISUs.

Workaround: Use the latest SS7 microcode package provided by Freescale.

System Number: 18767

Fix Plan: None at this time.
