### Description

```asn1
gsmCsV42TxKwindowSize OBJECT-TYPE 
SYNTAX Unsigned32 (1..255) 
ACCESS read-write 
STATUS mandatory 
DESCRIPTION 
"This attribute specifies the maximum number of outstanding 
unacknowledged sequenced Information (I) frames from the IWF to 
the remote entity. The default value is 15 frames, and if this value is 
used then no Exchange Identification (XID) negotiations are 
required for txKwindowSize. If the value set for txKwindowSize is 
other than 15, then XID frames are exchanged to negotiate a value. 
The value provided for txKwindowSize sets up the bounds during 
XID negotiations. The IWF performs XID negotiations with this 
value as a minimum or maximum value. If a value greater than 15 is 
specified, then the IWF attempts to negotiate a value between 15 (as 
a minimum) and the given value (as a maximum). If a value less 
than 15 is specified, then the IWF attempts to negotiate for a value 
between the given value (as a minimum) and 15 (as a maximum). 
Any value can be specified as long at it is within the provisionable 
limits. However, a value equal to or close to the default is 
recommended. 
The negotiated value can be viewed in the component 
GsmIwfV42Op attribute txKwindowSize. Changes to this attribute do 
not effect existing calls."
