Farallon Communications 412 Manual Do Utilizador

The Netopia ISDN Modem suppor ts Multilink PPP, which can link the 
two ISDN B channels and allow a maximum digital connection of 
128 Kbps. Multilink PPP is enabled by default.

If want to use Multilink PPP, make sure:

■

Multilink PPP is turned on in the Netopia ISDN Modem.

■

The serial por t of your PC or Macintosh computer suppor ts a 
data transmission rate of at least 115.2 Kbps and you’ve set 
the por t speed in your communications software to the 
maximum available data rate.

■

Both the telephone company ser vice and the Internet Ser vice 
Provider (ISP) or LAN dial-in ser vice suppor t two B channel 
connections. 

■

Both you and the destination you are calling are using software 
that suppor ts PPP, such as Dial-Up Networking in Windows 95 
or InterPPP and FreePPP in the Macintosh operating system.

The following registers control Multilink PPP and are set by your 
configuration software:

■

S register 80 enables or disables Multilink PPP operation

■

S registers 82 and 83 control Multilink configuration

■

S register 70 controls Dynamic Bandwidth Allocation (DBA) in 
Multilink mode

By default, the Netopia ISDN Modem dials the same number for 
both Multilink PPP channels. If the destination requires a different 
telephone number to establish a second Multilink PPP channel, then 
you must include this second telephone number in the dial string. 
The ampersand character (&) is used to dial two telephone 
numbers: for example, ATD19085557891 & 19085555555

Note: If you are using a Macintosh computer and a Model 411 
Netopia ISDN Modem, star t up the ISDN Setup application and 
enter the second telephone number (DN) in the Second DN field in 
the Advanced window. (For more information,
