Network Interfaces - Demand-dial - Options Tab

Applies To: Windows Server 2008

Dialog box element Description

Demand dial

Specifies that an idle time disconnect setting is used for nonpermanent dial-up connections.

Idle time before hanging up

Lists the available time periods for the idle time setting. The remote router that is called also has an idle time setting, which may be smaller than the setting here. In that case, the remote router will disconnect an idle connection before the time you set here.

Persistent connection

Specifies that the demand-dial connection is always in a connected state. The connection is established when the Routing and Remote Access service is started and is never disconnected by the calling router.

Redial attempts

Type the number of times to automatically redial the phone number. You can also click the arrows to select the number of redial attempts.

Average redial intervals

Lists the available time periods to wait between redial attempts.


Click to configure callback settings.

PPP Settings

Dialog box element Description

Enable LCP extensions

Specifies whether Link Control Protocol (LCP) extensions are enabled. LCP extensions may cause problems when you call servers with older PPP software. If consistent problems occur, clear the check box.

If you clear the check box, LCP cannot send Time-Remaining and Identification packets and request callback during the LCP negotiation of PPP.

Enable software compression

Specifies whether software compression is enabled.

Network Connections offers software data compression in addition to support for modem compression. Therefore, you do not have to turn on modem compression to benefit from faster throughput.

Negotiate multi-link for single link connections

Specifies whether Multilink negotiation is enabled for a single link connection. If your remote access server supports this feature, you may notice improved audio quality. If you enable this option, you may not be able to connect to other remote access servers.
