TCP Header Compression VJ Compression - It is used for TCP/IP protocol header compression. Normally it is set to None to improve bandwidth utilization.

Because our ISDN link type is “Dial On Demand”, the

 

connection will be initiated only when needed.

BOD stands for bandwidth-on-demand for Multiple-Link PPP

High Water Time

(ML-PPP or MP). High Water Mark/ High Water Time/

 

Low Water Mark/Low Water Time parameters are applied

 

when you set the Link Type to Dialup BOD. The ISDN

 

usually uses 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

 

(characters-per-second) measures the total link utilization.

 

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 These parameters specify the situation in which the second

Water Timechannel 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).

Note: If you are not sure whether your ISP can support BOD and/or ML-PPP’s features, please seek assistance from your ISP, local dealers or our website: support@draytek.com.

This function is used for G models only.

3.11.1 Basic Concepts

Over recent years, the market for wireless communications has enjoyed tremendous growth. Wireless technology now reaches or is capable of reaching virtually every location on the surface of the earth. Hundreds of millions of people exchange information every day via wireless communication products. The Vigor G model, a.k.a. Vigor wireless router, is designed for maximum flexibility and efficiency of a small office/home. Any authorized staff can bring a built-in WLAN client PDA or notebook into a meeting room for conference without laying a clot of LAN cable or drilling holes everywhere. Wireless LAN enables high mobility so WLAN users can simultaneously access all LAN facilities just like on a wired LAN as well as Internet access.

The Vigor wireless routers are equipped with a wireless LAN interface compliant with the standard IEEE 802.11g protocol. To boost its performance further, the Vigor Router is also
