Table 3-54 AVT Context Table: ABR-VS/VD Parameter Description
Parameter
Initial
Value
Comment
Config(6:0)
configure see Section 3.6.9.5 for mapping
TPi(15:0)
configure
Time Parameter corresponding to the Initial Cell
Rate (ICR); constant connection parameter; if the
SCAN detects the ADTF time-out it writes the TPi
value to the TPf field, i.e. it switches to ICR.
VCI/LCI(15:0)
configure cell header template: VCI/LCI of the ABR
connection (depends on LCI mapping)
VPI/LCI(11:0)
configure cell header template: VPI/LCI of the ABR
connection (depends on LCI mapping)
PTI(2:0)
configure
cell header template: value ignored by HW,
optionally in FW: if not 110 then discard RM cell
fragment
C
configure cell header template: CLP bit (=0)
MCRf*
configure Lower bound for VS ACR calculation
PCRf*
configure Upper bound for VS ACR calculation
RDF(3:0)
configure Rate Decrease Factor for VS ACR calculation
(given as right shift)
RIF(3:0)
configure Rate Increase Factor for VS ACR calculation
(given as right shift)
ADTF(9:0)
configure
ACR Decrease Time Factor (optional ABR
negotiation parameter, default 500 ms) for time-out
detection in SCAN
Flags(3:0)
0
reserved for internal use by IOP
F0
0
reserved for internal use by ABM-P core
EFCId
0
EFCI stored for downstream user cell
EFCIu
0
EFCI stored for upstream user cell
UDF1(7:0)
0
cell header template: UDF1 field (may contain part
of LCI, depends on LCI mapping)
UDF2(7:0)
0
cell header template: UDF2 field
CIb/NIb
0
CI/NI extracted from received BRM cells; used
together with ERb to calculate ACRf
