Members

dwVersion

Version number. The recommended range is 0 - 2; 2 is the default setting.

dwIws

Inter-working function (IWF) to the device window size. The recommended range for versions 0 and 1 is 0 - 61; 61 is the default setting. The range for version 2 is 0 - 480; 240 is the default setting. For more information about the related CELLXXX structures, see GSM specification 07.07 "Digital cellular telecommunications system (Phase 2+); AT command set for GSM Mobile Equipment (ME)." For more information about IWF, see Remarks.

dwMws

MS to IWF window size. The recommended range for versions 0 and 1 is 0 - 61; 61 is the default setting. The range for version 2 is 0 - 480; 240 is the default setting.

dwAckTimer

Acknowledgement timer [T1] in milliseconds. The recommended range is 380+; 500 is the default setting.

dwRetransmitAttempts

Retransmit attempts [N2]. The recommended range is >0; 6 is the default setting.

dwResequenceTimer

Resequence timer [T4] in milliseconds. The recommended range is >25; if dwVersionis 1 then is 30 is the default setting for 14.5 kilobit full rate, if dwVersionis 2 then 50 is the default setting for 14.5 kilobit full rate.

Remarks

Inter-working function (IWF) is a component in a system that connects two different types of networks (such as frame relay and ATM) and enables endpoints attached to one network to communicate with endpoints attached to the other network. The TSP does not set defaults; however, recommended values are given. An application may use lineGetDevConfigto determine the current settings.
