ECE Lt Router Figure 3 1 Router in an ISDN Network BRI Leased Line Operation for Germany For BRI service in Germany the router allows you to support a permanent point to point ISDN connection over a B channel without having to use the D channel to dial the call This connection operates like a leased line This option is useful when ISDN service providers do not use the D channel Leased line operation supports PPP Bay Networks Standard and Frame Relay protocols Site Manager allows you to select leased line operation when you configure the application mode for your BRI interface Refer to Chapter 4 for more information BRI Subaddresses The ITU T specifies that the same S T interface can have eight different TE devices for example routers However the service provider may assign only one phone number for the customer side of the local loop To determine the specific destination of the call the router uses a subaddress Each router has an assigned subaddress for which it will accept calls The subaddress must be part of the incoming call setup message sent to the router Based on the subaddress the router determines if the call is intended for it If not it ignores the call 3 4 Implementation Notes BRI Floating B Service for the AN and ANH If your ISDN service provider only offers 2B D service the floating B option for the AN and ANH enables you to use only one

35. Figure 3 8 Implementation Notes These features are particularly beneficial for bandwidth on demand configurations where the router activates additional switched lines to relieve congestion over a primary line You should always select PPP multilink when you configure bandwidth on demand circuits When you enable multilink you can group a set of lines between two routers into a single bundle which can consist of up to four links of different speeds Each bundle belongs to a separate circuit Multilink distributes traffic over each logical line in a bundle in an amount roughly proportional to the effective bandwidth of the link The router sending information divides the outbound traffic among all the lines in the bundle keeping each packet intact Once data reaches the destination router multilink resequences packets arriving on different lines Figure 3 8 shows how multilink and bandwidth on demand work together In this figure you configure one router as the congestion monitor This router monitors traffic volume over the primary line If the monitor router detects congestion it brings up an additional line in this case an ISDN B channel If the traffic is still heavy the monitor router brings up additional channels until congestion is relieved Multilink Multilink and Bandwidth on Demand Operation For more information about PPP multilink see Configuring PPP Services 3 25 Configuring Dial

Services Protocol Prioritization When you configure your router you can prioritize the traffic sent across a synchronous line interface by using protocol prioritization Being able to prioritize traffic is important for your time sensitive applications For example a user at Router A participating in a Telnet session with Router B requires a more immediate response than does a user at Router A performing a file transfer with Router B When you configure a bandwidth on demand circuit the router automatically enables protocol prioritization on the primary and secondary line because PPP requires priority for control messages Note Do not configure protocol prioritization for bandwidth on demand circuits running PPP multilink For more information about protocol prioritization see Configuring Traffic Filters and Protocol Prioritization Defining the Role of the Router in the Network Bandwidth on demand circuits are point to point connections For each circuit you must designate a router at one end of the connection as the congestion monitor The congestion monitor checks the congestion of the lines in a multilink bundle If this router discovers congestion it activates secondary lines The router at the other end of the connection the nonmonitor router does not have the authority to activate a secondary line It is important to define the role of each router on the link to avoid both routers bringing up a second line simultaneously
