### Description

```asn1
gsmCsV42T402AckDelayTimer OBJECT-TYPE 
SYNTAX FixedPoint2 (25..450) 
ACCESS read-write 
STATUS mandatory 
DESCRIPTION 
"This attribute specifies the maximum amount of time that the IWF 
may wait following the receipt of any frame requiring a reply before 
it initiates transmission of an appropriate reply in order to ensure 
that the reply frame is received by the remote error-correcting entity 
prior to expiration of the T401 timer of the remote error-correcting 
entity. Since information about the T402 timer is not carried in the 
Exchange Identification (XID) negotiations at call setup, both sides 
operate with different timer values. If this timer expires, then the 
reply that would have been returned prior to its expiration is not 
sent. The performance of the data link layer can be impacted by the 
value of this timer as retransmissions of frames occur on expiry of 
timer T401. For better performance, a value of t402AckDelayTimer 
(T402) equal to half the value of t401AckTimer (T401) is 
recommended. 
Changes to this attribute do not effect existing calls."
