Preliminary PM73124 AAL1gator™-4
4 Link CES/DBCES AAL1 SAR
• Queues are added by making entries
into an add queue FIFO to minimize
queue activation overhead.
RECEIVE SECTION
• Provides per-VC configuration of time
slots allocated, partial cell size,
sequence number processing options,
cell delay variation tolerance buffer
depth, maximum buffer depth.
• Supports Fast Sequence Number
processing and Robust Sequence
Number processing.
TYPICAL APPLICATIONS
INTEGRATED ACCESS DEVICE
GENERAL
• Provides a microprocessor interface
for configuration, management, and
statistics gathering.
• Provides single maskable, open-
collector interrupt with master interrupt
register to facilitate processing for
AAL1, RAM and UTOPIA exceptions.
