Lab 4.2.1 Configuring ISDN BRI (U-Interface)

This lab assumes that a router with an ISDN BRI U interface is available. An Adtran Atlas550 ISDN emulator is used to simulate the switch/ISDN cloud. If an ISDN router is not available, review the lab and perform as many, non-interface commands as possible. Cable a network similar to the one in the diagram above. Any router that meets the interface requirements displayed on the above diagram may be used. This includes the following and any of their possible combinations: | Cisco SrsTEMS Lab 4.2.1 Configuring ISDN BRI U-lnterface Router Router Enable Secret Passwords FastEthernet 0 Address BRI 0 Adtran Designation Name Password Subnet Mask address Connection Router Ottawa class cisco 192.168 14.1 24 NA BRI 1 Straight-through cable Serial cable Console rollover Crossover cable Objective Configure an ISDN router to make a successful connection to a local ISDN switch.

Please refer to the chart at the end of the lab to correctly identify the interface identifiers to be used based on the equipment in the lab. The configuration output used in this lab is produced from 1721 series routers. Any other router used may produce slightly different output. Conduct the following steps on each router unless specifically instructed otherwise. Start a HyperTerminal session as. Note Refer to the erase and reload instructions at the end of this lab. Perform those steps on all routers in this lab assignment before continuing. Step 1 Configure the routers Configure all of the following according to the chart The hostname The console The virtual terminal The enable passwords If there is a problem completing this refer to the Network Address Translation NAT configuration lab. Step 2 Verifying the ISDN BRI switch type a. Not all ISDN switch types are the same worldwide and the first step is to .
