TDAT042G5 Device Advisory
for Version 1 and 1A of the Device
Advisory
May 2001
Data Engine (DE) (continued)
DE3. ATM Transmit Count of Idle Cells
For ATM mode in the transmit direction, all cells are currently counted, including the idle cells. Only the cells con-
taining data should be counted.
Workaround
No workaround is available for this condition.
Corrective Action
This condition will be addressed in version 1A of the device.
DE4. Channel Provisioning
When using the device in STS-3/STM-1 and STS-12/STM-4 modes with either PPP, CRC, or HDLC, egress config-
uration registers 0x1016, 0x1017, 0x1018, and sequencer cell state register 0x1036 of all four channels must be
provisioned, even if a channel is not being used.
Workaround
Provision all four transmit DE channels. Set DE egress configuration registers and the sequencer cell state register
as shown in Table 2.
