Call Control Setup
Dial Retry - It specifies the dial retry counts per triggered
packet. A triggered packet is the packet whose destination is
outside the local network. The default setting is no dial retry.
If set to 5, for each triggered packet, the router will dial 5
times until it is connected to the ISP or remote access router.
Dial Delay Interval - It specifies the interval between dialup
retries. By default, the interval is 0 second.
Remote Activation – It can help users who would like to
access the server which is off the Internet in the head office.
To remotely make the server to be available on the Internet,
i.e. make the router in the head office activating its Internet
access either by dialing-up or starting broadband connection,
users can make a regular phone call (the number is set in the
Remote Activation field) to the router as signaling it for
activation. The phone call will be soon disconnected once the
router is on line.
Note that Dialing to a Single ISP should be
pre-configured properly.
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.
PPP Authentication - 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.
