ICTVÑIngress CLP Transparency Value
This bit determines the value that should be written to a cellÕs header if the ICTEÑIngress CLP Transparency Enable bit is set.
See Section 6 for details.
ICTEÑIngress CLP Transparency Enable
This bit determines whether CLP should be copied to the IOCLPÑIngress Overhead CLP bit and whether the ICTVÑIngress
CLP Transparency Value bit should be written to the cell header CLP. See Section 6 for details.
0 = The ingress header CLP bit is not touched.
1 = CLP should be copied from the cell header to the ingress switch parameters. The ICTVÑIngress CLP Transparency
Value bit should be written to the cell header CLP.
CIMEÑConnection Ingress Marking Enable
This bit enables marking of cells which are received in the ingress. See Section 5.4.3 for details.
0 = Marking of cells which are received in the ingress is disabled.
1 = Marking of cells which are received in the ingress is enabled.
12.2. CONTEXT PARAMETERS TABLE
Some bits have been added, and some bit deÞnitons have been updated in the Egress Parameters Word and the Ingress
Parameters Word. These bits are in bold.

EP6RÑEgress PTI 6 Remove
When this bit is set and the CRRP-VC RM cell removal point is set, then an egress cell whose PTI = 6 is removed, provided
that the connection is a VC connection.
EP7RÑEgress PTI 7 Remove
When this bit is set and the RRP-RM cell removal point is set, then an egress cell whose PTI = 7 is removed, provided that the
connection is a VC connection.
EEOTÑEgress End-to-End OAM Termination
When this bit is set, the egress ßow is treated as the terminating point of the OAM end-to-end cell ßow for the connection.
Additionally, if the CRRPÑVC RM Cell Removal Point bit is reset, then cells with PTI = 6 or 7 are removed at this point.

IP6RÑIngress PTI 6 Remove
When this bit is set and the RRP-RM Cell Removal Point is set, then an ingress cell whose PTI = 6 is removed, provided that
the connection is a VC connection.
IP7RÑIngress PTI 7 Remove
When this bit is set and the RRP-RM Cell Removal Point is set, then an ingress cell whose PTI = 7 is removed, provided that
the connection is a VC connection.
IEOTÑIngress End-to-End OAM Termination
When this bit is set, the ingress ßow is treated as the terminating point of the OAM end-to-end cell ßow for the connection.
Additionally, if the CRRPÑVC RM Cell Removal Point bit is reset, then cells which belong to a VC connection and whose PTI =
6 or 7 are removed at this point.
