86 CHAPTER 7: ADVANCED CONFIGURATION OF PORTS AND PATHS
Configuring Dial-Up
over PPP with
Modems or TAs
This section describes two dial-up scenarios:
■ Scenario 1: Single Destination per Port
■ Scenario 2: Multiple Destinations
ISDN TAs If you are using both B channels together for a 128 Kbps connection,
each TA used at each end of the connection must support the same B
channel aggregation protocol: Multilink PPP or bonding.
You cannot use each B channel independently on an external ISDN TA.
Scenario 1: Single Destination per Port
This scenario shows a model 44x bridge/router connecting to one
destination on each serial port.

Create the dial number list for ports 5 and 6:
ADD !5 -PORT DialNoList "1-408-555-7000" Baud = 128 Type = Bri
ADD !6 -PORT DialNoList "1-510-555-9876" Baud = 28.8 Type = Modem
Set the normal bandwidth for ports 5 and 6:
SETDefault !5 -PORT NORMalBandwidth = 128
SETDefault !6 -PORT NORMalBandwidth = 28.8
