tdmaBcV42T1AckTimeouts

Module: Nortel-Magellan-Passport-TdmaIwfMIB

OID (symbolic): Nortel-Magellan-Passport-TdmaIwfMIB::tdmaBcV42T1AckTimeouts

OID (numeric): 1.3.6.1.4.1.562.2.4.1.136.8.11.1.6

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 tdmaBcV42T1AckTimeouts?

A Counter32 of how many times the T401 acknowledgment timer has expired during this data call. It wraps on overflow; if this happens frequently, the note in the MIB itself suggests the operator increase the provisioned T401 acknowledgment timer, since each timeout causes V.42 to resend the unacknowledged frame.
