4.2.7.8
Besides the standard ATM Forum service categories, other generic service classes can
be flexibly supported by the ABM-P.
Quality of service differentiation in terms of absolute and relative guarantees can be
achieved for any traffic stream that is segmentable into the ABM-P cell format.
4.2.8
Initialization of the AVT Context RAM entry is required for each ABR connection QID, to
initial values as indicated in the respective tables.
4.2.8.1
Enabled per traffic class together with Relative Rate Marking by setting ABRen=1. No
connection specific action required.
EFCI Marking must be globally enabled in the

4.2.9
After reset, the ERC unit automatically starts loading the firmware necessary for ABR-
ER and ABR-VS/VD from the external serial EEPROM via the SPI interface.
In either case, firmware download completion is indicated by status bit ‘FWDF’ (bit 15)
in register
microprocessor. At this time, the ERC will start to run the firmware initialization and self-
test routines. Completion of firmware initialization will be reported to the external
microprocessor by a message via the ERC microprocessor mailbox (ERCMB0=4000
