segmentation VCC table entry.
The host allocates a region of SAR SEG-shared memory for the segmentation
VCC table at system initialization, based on the maximum number of connections
and the maximum number of ABR connections. The host informs the SAR of the
location of the table through the internal base register, SEG_VBASE
(SEG_VCCB).
entries in the table. The host describes the SEG VCC by initializing the SEG VCC
table entry including the SCH_STATE portions of the assigned VCC. The
VCC_INDEX, defined as the offset into the table in 10-word increments,
uniquely identifies a segmentation channel. In all communication between the
SAR and the host, a VCC_INDEX field specifies a VCC.
The VCC table entry contains generic information common to all traffic
Once a table has been established, the host assigns segmentation VCCs to
