86CHAPTER 7: ADVANCED CONFIGURATION OF PORTS AND PATHS

Configuring Dial-Up over PPP with Modems or TAs

ISDN TAs

This section describes two dial-up scenarios:

■Scenario 1: Single Destination per Port

■Scenario 2: Multiple Destinations

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.

Start here

Set the normal bandwidth for ports 5 and 6:

SETDefault !5 -PORT NORMalBandwidth = 128

SETDefault !6 -PORT NORMalBandwidth = 28.8

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

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

Syntax: ADD !<port> -PORT DialNoList "<phone no>" [Baud = <rate> (1.2–16000)] [Type = Modem Bri Sw56] [Pos = <number>]
