Module: Nortel-MsCarrier-MscPassport-TdmaIwfMIB

OID (symbolic): Nortel-MsCarrier-MscPassport-TdmaIwfMIB::mscTdmaBcV42T1AckTimeouts

OID (numeric): 1.3.6.1.4.1.562.36.2.1.136.8.11.1.6

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: This attribute counts the total number of times that the T401 timer has timed out within a data call. If this timer times-out frequently, the operator may need to adjust the provisioned parameter T401 acknowledgment timer to a larger time amount, since every time that V.42 sends out a frame it sets the T401 timer to wait for the peer's acknowledgment of the frame. When the timer times-out and no acknowledgment has been received, the V.42 sends the same frame to its peer. The counter wraps when it exceeds the maximum value.

What is mscTdmaBcV42T1AckTimeouts?

A wrapping counter of how many times the T401 acknowledgment timer expired during this data call without receiving an acknowledgment, triggering a frame retransmission each time. The MIB itself suggests that frequent timeouts here mean the operator should consider raising the provisioned T401 acknowledgment timer value to better match actual round-trip conditions on this link.
