### Description

```asn1
gsmCsV42T400DetectTimer OBJECT-TYPE 
SYNTAX FixedPoint2 (75..254) 
ACCESS read-write 
STATUS mandatory 
DESCRIPTION 
"This attribute specifies the maximum amount of time that the IWF 
waits for an Originator Detection Pattern (ODP) or Answerer 
Detection Pattern (ADP). ODP/ADP is a series of special bit 
patterns used during the call setup procedures. 
If the IWF is the Originator of the call, it starts sending ODP 
patterns and waits for an ADP for the duration of T400 milliseconds 
from the answerer at call setup time. 
If the IWF is the Answerer of the call, it waits for an ODP for T400 
seconds from the originator and if it receives during that time it 
sends an ADP pattern to the originator at the call setup time. Since 
both sides operate with different values of T400 timer, a higher 
value increases the chance of a successful call setup. 
Changes to this attribute do not effect existing calls."
