Basic Setup | Link Type - Because ISDN has two B channels (64Kbps/per |
| channel), you can specify whether you would like to have |
| single B channel, two B channels or BOD (Bandwidth on |
| Demand). Four options are available: Link Disable, Dialup |
| 64Kbps, Dialup 128Kbps, Dialup BOD. |
PPPAuthentication - It specifies the PPP authentication method for PPP/MP connections. Normally you can set it to PAP/CHAP for better compatibility.
TCP Header Compression - VJ Compression: It is used for TCP/IP protocol header compression. Normally it is set to Yes to improve bandwidth utilization.
Idle Timeout - Because our ISDN link type is Dial On Demand, the connection will be initiated only when needed.
(BOD) Setupor MP). The parameters are only applied when you set the Link Type to Dialup BOD. The ISDN usually use one B channel to access the Internet or remote network when you choose the Dialup BOD link type. The router will use the parameters here to decide on when you activate/drop the additional B channel. Note that cps
High Water Mark and High Water Time - These parameters specify the situation in which the second channel will be activated. With the first connected channel, if its utilization exceeds the High Water Mark and such a channel is being used over the High Water Time, the additional channel will be activated. Thus, the total link speed will be 128kbps (two B channels).
Low Water Mark and Low Water Time - These parameters specify the situation in which the second channel will be dropped. In terms of the two B channels, if their utilization is under the Low Water Mark and these two channels are being used over the High Water Time, the additional channel will be dropped. As a result, the total link speed will be 64kbps (one B channel).
