Async to Sync PPP Connection
Increasingly, Internet Service Providers (ISPs) are offering their services
through dial-up ISDN lines for higher data bandwidth demands.
Equipment used at the service providers location is usually an ISDN
router or Remote Access Server, whichunlike terminal adapters (TAs)
lacks asynchronous capability. For that reason, ISDN TAs that support
only V.120 or other async protocols will not work with the router-based
servers at the ISP site.
The support of async-to-sync PPP conversion permits the PC Card to
connect to your router-based ISPs with the incorporation of TCP/IP
software packages. Furthermore, Multi-Link PPP protocol permits a 128
Kbps ISDN connection when applications are bandwidth critical.
Set the Single-Link PPP mode as follows:
AT!Z=9 Set async-to-sync PPP conversion mode
AT&N0=0 Set Single-Link mode
Set the Multi-Link PPP (MLPPP) mode as follows:
AT!Z= Set async-to-sync PPP conversion mode
AT&N0=1 Set Multi-Link mode
To enable async-to-sync PPP conversion protocol with the Configuration
Utility:
1. In the Configuration Utilty, click the COM Port Setting tab.
2. Then select PPP.
