atmTrunkingBrVccCuTimer
Module: ACMIB
OID (symbolic): ACMIB::atmTrunkingBrVccCuTimer
OID (numeric): 1.3.6.1.4.1.1751.2.18.28.4.1.44
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: CuTimer represents combined use timer, is set to zero such that every ATM cell transmitted contains one, and only one, AAL2 packet, and the first octet of the AAL2 packet header follows immediately after the Start Field in the ATM cell payload. If the AAL2 packet payload is less than 44 octets, the remainder of the ATM cell payload following the end of the AAL2 packet shall be filled with zeros as padding. Each increment of CuTimer means 5ms more to wait. And cuTimer default value 4 means to wait 20ms before the ATM cell is sent out.
What is atmTrunkingBrVccCuTimer?
This OID sets the Combined Use Timer (range 0-8) that determines how ATM cells package AAL2 voice/data packets, where 0 means one AAL2 packet per ATM cell. Engineers tune this parameter to balance cell packing efficiency against latency—higher values pack more data per cell but add buffering delay. For example, setting it to 0 ensures low latency for voice by keeping each cell focused on one packet, while setting it to 4 allows more payload per cell for better trunk utilization.
