Concepts and Principles of Operation 6 Physic al Inte rface The ISDN physical interface is a av ailable in two types, U and S/T. The S/T interface relies on a external device called NT1 to connect th e user equipment to the ISDN line. The S/T interface is used in most parts of the world.
Concepts and Principles of Operation 7 Directory numbers A directory number is th e address or tele phone number for t he ISDN line ass igned by your ISD N service provider or t elephone com pany. The number of directory nu mbers allocated depends on which Servi ce Provider you are using.
Concepts and Principles of Operation 8 Service type Number of channels DA64 One B-channel DA128 Two B ch annels Data Communication Serv ices Two widel y used i nter -net work ing mecha nis ms are bri d ging a nd ro uting. Br i dgi ng o ffer s a straightforward method of interconnectin g network segments.
Concepts and Principles of Operation 9 Intern et and Intranet Connection Profil es Hypertec ISD N 10T Router m aintains two conn ection profiles one for Intern et and the oth er for Intranet. The Intern et co nnection b y def inition is for users to reach Internet, the Intranet connection is made betw een two offices.
Concepts and Principles of Operation 10 You can s et Hypertec Router IP ad dresses to be ' un-num bered' or ‘num bered’. B y setting it to “ un- numbered”, you can route IP over a link betw een two devices withou t assigning IP addresses to the ISDN interfaces.
Concepts and Principles of Operation 11 IPX IPX is th e protocol used by Novel N et ware as the network l ayer protocol. Nove l IPX also uses Routing Information Protocol (RIP) for routin g protocol. The IPX address con sists of tw o parts: a 4- byt e network number, an d a 6- byte node num ber.
Concepts and Principles of Operation 12 RIP Novel IPX also uses Routing Inform ation Protocol (R IP) as a rout ing protocol . Although i t is simil arly name d to the IP equiv alent, it uses a di fferent protocol . IPX RIP broa dcasts packet s to the netw ork every 60 secon ds to inform other IPX routers or servers about its network.
Concepts and Principles of Operation 13 Hypertec ISDN 10T Ro uter to negotiate for either PA P o r CH AP authentication protoco l wh iche ver the remote end prefers . Multili nk PPP The PPP Multilink Protocol (RFC 1717) is a stan dards based extension of the PPP (Poin t-to- Point Protocol) standard.
Concepts and Principles of Operation 14 Dial on Dem and When the ISDN router receiv es packets from the Ethernet and decides to rou te packets to the WAN interface, an ISDN call is automatically made to the remote en d, followed b y the PPP negotiation.
Concepts and Principles of Operation 15 diagram, traff ic decreases temporarily before in creasing again. Because bandwidth requ irements can change sudden ly like this, the second B-channel waits for a period of time before closing dow n. In the above diagram, this value has been set to 5 seconds.
Concepts and Principles of Operation 16 packets are to be filtered or for warded. If no access list is speci fied, all valid packet s will be forwarded.
Concepts and Principles of Operation 17 DHCP Managing IP addresses in an organization is often a h eadache for the MIS staffs. To ease the IP add ress manage ment, the D ynamic Hos t Con fi gur atio n P ro t oco l (DHC P ) is i nvented by IE T F. D HCP protocol w orks in a client server configurati on.
Concepts and Principles of Operation 18 You must tell your serv ice provider how you need the line conf igured for data, voice and other optional services. Your service provider needs to tell you: • the ISDN service and switch type • the ISDN directory (or ph one) numbers • associated Service Profile Iden tifiers (SPIDs) (if required).
Concepts and Principles of Operation 19 Provis ioning the ISD N Line To make sure that you get the correct ISDN serv ice for the Hyperte Router, you must tell your service provider how you need the ISDN line provisione d.
Concepts and Principles of Operation 20 Solutio n Sets Solution Sets have bee n created to correspond to a particular customer application. T he Solution Sets appropriate to the Hy pertec Router are: Solution Set ISDN Service Work at Hom e 3a Provides v oice on one B ch annel and data on the other B chan nel.
Concepts and Principles of Operation 21 Using Specific Sw itch P arameter s Your service provider may require specific details about the para meters for the switc h you are connected to.
Concepts and Principles of Operation 22 When conn ecting to AT&T 5ESS C ustom, you are prov ided with one telephone num ber (directory number). If y ou only need to connect one analog device (say a telephone) then one number is all that is required, but if you have two analog devices then you will need to subscribe to MSN.
Configur a 23 from a web brow ser are delivered to a software m odule called EasyWeb, which translates the HTTP requests into SNMP reques ts and forwards them to the Hypertec ISDN 10T Router. The ISDN router returns the SNMP responses to the EasyWeb which in turn translates them back into HTTP responses and forwards th em back to the browser.

Turn the power off and on again, observe the alarm (ALM) LED During power-up self-test, the AL M LED flash es.
Troubleshooting 63 4. Monitor the status of the D channel LED When you are connected to a live ISDN line, the D channel LED will be lit or flashing. If the D channel LED remains off, it indicates that no ISDN si gnal present. It is likely that there is a poor conn ection to the local telephone company.
Troubleshooting 64 8. If your are unable to comm unicate with the router through NMS.
