• Priori ty level 4 (P4) —You need information or assistance concerning Cisco product capabilities,

product installation, or basic product configuration.

• Priori ty level 3 (P3) —Your network pe rformance is degraded. Network functionality is noticeably

impaired, but most business operations continue.

• Priori ty level 2 (P2) —Your production network is severely degraded, affecting significant aspects

of business operations. No workaround is available.

• Priority level 1 (P1)—Your product ion n et w ork is d own , a nd a c rit ica l im pac t to b us ine ss op erat io ns

gateways. No te that th e l at ter r eq u ir es u s e of C isco IOS rel ease 1 2.2(2)XB o r lat er.

This chapter provides a brief profile of the Cisco AS5350 and Cisco AS5400 universal gateway hardware compon ents and fu ncti onalit y , det ails how to us e the Ci sco IOS command-line interf ace (CL I), and describes how to upgrade your Cisco IOS software:

The Cisco AS5350 and Cisco AS5400 universal gateways are ve rsatile data and voic e communications platform s t hat pr o vide t he fu nc tions of a gat e w ay, router , and di gita l mode ms i n a s ing le mod ul ar c has sis.

The gateways are intended for Internet service providers (ISPs), telecommunications carriers, and other service providers that offer managed Internet connections, and also medium to large sites that provide both digital and an al og ac ces s to u s er s o n an en ter p r ise ne two r k.

Basic Ha rdwar e Architecture

Note The cards that reside in the AS5350 and AS5400 chassis, sometimes referred to as dial feature cards

(DFC), ar e of two ty pe s: tr unk cards , whic h pro vid e a n E1, T1, or T3 inte rf ace , and un i v ers al po rt c ards , which host the universal digital signal processors (DSPs) that dynamically handle voice, dial, and fax calls.

Figure 1-1 shows the following:

• Client m o de m s and Int egr at ed Serv ice s D ig it al Networ k ( IS D N ) r outers dial into the ga teway

through the public switched telephone network (PSTN).

• Analog Point-to-Point Protocol (PPP) calls connect to modems inside the gateway.

• Each mode m inside the gateway provides a corresponding TT Y line and asynchronous inte rface for

terminating character and packet mode services.

• Asynchronous interfa ces clone their configurations from a group-async interface.

• Synchronous PPP calls connect to serial interface channels (for example, Se2/0:1 and Se2/0:2).

• Synchronous interfa ces clone their configurations from a dialer interface.

One analog PPP call uses the following resources:

• One T1 DS0 channel

• One chan n el i n a TDM bus

• One integ ra ted modem

• One TTY line

• One asynchronous interface

One synchronous PPP call uses the following resources:

• One T1 DS0 channel

• One serial interface channel

Exploring the Cisc oIOS File System

The Cisc o IOS F i le System (I FS ) f eat ure provides a single in ter fa ce to the following:

Understan di ng C om man d Modes

Y ou need to use many different command modes to configure the gateway. Each command mode restricts you to a subset of commands.

Tip If you are having trouble ente ring a command, check the prompt, and then enter the question mark (?)

for a list of available commands. You might be in the wrong command mode or us ing the wrong syntax.

In the fol lowin g example, no ti ce h ow th e prompt ch an g es a ft er ea ch co mm a nd t o in di cat e a new command mode:

The last message is normal and does not in dicate a n error. Press Return to get the Router> prompt.

Note You can press Ctrl-Z at any time to im med i ately retu r n to en ab le m o de ( Router#), instead of entering

exit, wh ic h return s y o u t o the previo us m o de .
