Module: Nortel-MsCarrier-MscPassport-AtmCoreMIB

OID (symbolic): Nortel-MsCarrier-MscPassport-AtmCoreMIB::mscAtmIfVptVccTmAbrAcrDecreaseTimeFactor

OID (numeric): 1.3.6.1.4.1.562.36.2.1.114.9.20.7.2.110.1.18

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-only

Description: This attribute indicates the Allowed Cell Rate Decrease Time Factor (ADTF) parameter for this connection.

ADTF is the time interval permitted between sending forward Resource Management (RM) cells before the Allowed Cell Rate (ACR) is decreased to initialCellRate. In other words, if the source does not transit a forward RM cell for the period specified by adtf, it reduces its ACR to the value of its initialCellRate.

For nailed-up connections, this attribute is determined by the provisioned value of the acrDecreaseTimeFactor attribute. For signalled connections, it is indicated in the ABR Additional Parameters Information Element.
