One day an out of work mimic(滑稽演员) is visiting the zoo and attempts to earn some money as a street performer. As soon as he starts to draw the crowd,a zoo keeper grabs him and drags him into his office. The zoo keeper explains to the mimic that the zoo's most popular attraction,a gorilla(大猩猩),has died suddenly and the keeper fears that attendance at the zoo will fall off. He offers the mimic a job to dress up as the gorilla until they can get another one. The mimic accepts.

So the next morning the mimic puts on the gorilla suit and enters the cage before the crowd comes. He discovers that it's a great job. He can sleep all he wants,play and make fun of people and he draws bigger crowds than he ever did as a mimic. However,eventually the crowds tire of him and he tires of just swinging on wires. He begins to notice that the people are paying more attention to the lion in the cage next to his. Not wanting to lose the attention of his audience,he climbs to the top of his cage,crawls across a partition(隔离物),and dangles from the top to the lion's cage. Of course,this makes the lion very angry,but the crowd loves it.

At the end of the day the zoo keeper comes and gives the mimic a raise for being such a good attraction. Well,this goes on for some time-the mimic keeps taunting the lion,the crowds grow larger,and his salary keeps going up. Then one terrible day when he is dangling over the angry lion he slips and falls. The mimic is terrified.

The lion gathers itself and prepares to attack. The mimic is so scared that he begins to run round and round the cage with the lion close behind. Finally,the mimic starts screaming and yelling,“Help me,help me!”But the lion is quick and attacks. The mimic soon finds himself flat on his back looking up at the angry lion and the lion says,“Shut up,you idiot!Do you want to get us both fired?”

ISDN的接口可以是PRI或BRI。ISDN的信道有两种类型:B和D。B信道主要是用来运送数据的工具,每个B信道拥有最大可达64kb/s的吞吐量,主要用于电路交换的数据通信,也可用于基于包交换的数据通信。D信道用来传输请求ISDN交换的信令。实际上, D信道提供一个到电信提供商中心局的本地回答,也可用于传送基于包交换的数据(如 X.25)。BRI是最典型的ISDN连接,并且是路由器上的一个本地ISDN接口,基本带宽是 2B+D。


在ISDN的BRI安装中,NT1(NT2)是一个重要的小设备,NT1类似于串行连接中用到的CSU/DSU,它是终接本地回路的设备(其实NT1就是一个将电话2线变4线的设备)。NT1至少有2个接口:一个S/T接口和一个U接口。S/T接口连到路由器的BRI接口上;U接口连接到ISP提供的插座上。许多具有BRI功能的Cisco路由器都有一个集成的NT1接口。这些接口都有一个BRIU标签,如果底板上没有这个特性,则接口会标BRIS/T,从而需要一个外部的NT1。这个本地的ISDN接口就是路由器的TE1接口。TE1终端适配卡专用于连接ISDN。
以下是路由器部分的配置清单:
Router(config)# ISDN switch-type basic-5ess
Router(config)# interface BRI0
Router(config-if)# ip add 192.168.10.1 255.255.255.0
Router(config-if)# encapsulation PPP
Router(config-if)# dialer idle-time out 1 80
Router(config-if)# dialer mapip 192.168.10.2 07314433018 (1)
Router(config-if)# dialer-group1
Router(config)# dialer-list protocol ip permit
