CELLRADIOLINKINFO (Windows Embedded CE 6.0)

1/6/2010

This structure contains radio link protocol settings. Radio link protocol is a link layer correction protocol that increases the perceived reliability of the air link.

Syntax

typedef struct cellradiolinkinfo_tag {
    DWORD dwVersion;
    DWORD dwIws;
    DWORD dwMws;
    DWORD dwAckTimer;
    DWORD dwRetransmitAttempts;
    DWORD dwResequenceTimer;
} CELLRADIOLINKINFO, *LPCELLRADIOLINKINFO;

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 dwVersion is 1 then is 30 is the default setting for 14.5 kilobit full rate, if dwVersion is 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 lineGetDevConfig to determine the current settings.
