AAL for Proprietary Traffic
The CN8236 incorporates an AAL0 traffic class for both segmentation and
reassembly, which acts as an AAL level for proprietary use. Several options for
packetization are implemented.
Optional Local Processing of ATM Management Traffic
The CN8236’s Local Processor Interface allows for an optional local processor to
direct segmentation and reassembly of ATM management level traffic, such as
Operations and Maintenance (OAM) cells, Performance Monitoring (PM) cells,
signalling, and Interim Local Management Interface (ILMI) traffic. This
off-loads network control traffic from the host, thereby focusing host processing
power on the user application.
Internal SNMP MIB Counters
CN8236 has three internal counters that measure cells received, cells discarded,
and AAL5 PDUs discarded (to meet ILMI and RFC1695 requirements).
CompactPCI Hot Swap
Circuity and I/O have been added in to functionally comply with the CompactPCI
Hot Swap Specification (PICMG 2.1 R1.0). Refer to sections 7.2 and 3.1.8 of the
specification for details of the Hot Swap operation. The HSWITCH* input
indicates the state of the handle switch. A logic low indicates that the handle is
locked, whereas a logic high indicates that the handle is unlocked. The HLED*
output is a 12 mA open drain capable of driving an LED directly. A logic low
illuminates the LED. The HENUM* output is an 8 mA open drain in compliance
with the ENUM# signal defined in the CompactPCI specification.
