Scenario 2: Using Both B Channels Together

If you need to connect to one location at 128 Kbps, use both B channels together.

The destination must be running Multilink PPP, either on the NETBuilder bridge/router with a built-in ISDN port or on the TA.

!3

!3.1 & !3.2 (paths)

B1 & B2: 128 K

1-408-555-1000

Both B channels connect to one destination.

Start here

Add path 3.2 to port 3:

ADD !3 -PORT PAths 3.2

Syntax: ADD !<port> -PORT PAths <connectorID.channelID> [,...]

Set the normal bandwidth for port 3:

SETDefault !3 -PORT NORMalBandwidth = 128

Syntax: SETDefault !<port> -PORT NORMalBandwidth = <kbps> (>=0)

Enable Multilink PPP on port 3:

SETDefault !3 -PPP MlpCONTrol = Enabled, NoFragment

Syntax: SETDefault !<port> -PPP MlpCONTrol = ([Enabled Disabled], [Fragment NoFragment])

Create the dial number list for port 3. If you have one phone number for your destination, enter the number twice with a letter after the second entry. If you have two numbers, enter each phone number:

ADD !3 -PORT DialNoList "1-408-555-1000" Baud = 64 Type = Bri ADD !3 -PORT DialNoList "1-408-555-1000a" Baud = 64 Type = Bri

Syntax: ADD !<port> -PORT DialNoList "<phone no>"

[Baud = <rate> (1.2–16000)] [Type = Modem Bri Sw56] [Pos = <number>]

Done

Scenario 3: Connecting to Multiple Destinations

If you need to connect to multiple destinations using one or both B channels, use a dial pool that contains all ISDN paths. The following scenarios show how a SuperStack II bridge/router using a dial pool can connect to three different locations.
