5. The Point to Point Protocol PPP is the de facto standard as the link encapsulation protocol for Internet Access PPP consists of a suite of protocols including LCP PAP CHAP IPCP and other related protocols Link Control Protocol LCP is used to negotiate the link parameters such as what authentication protocol to use LCP is specified in RFC 1570 Password Authentication Protocol PAP and Challenge Authentication Protocol CHAP are used to inform the remote site eg ISP about which router is connecting to it CHAP and PAP are specified in RFC 1334 IPCP is used to negotiate IP specific parameters such IP address IPCP is specified in RFC 1332 PAP CHAP When a CHAP authentication connection to the ISP is attempted the remote router or access server sends a CHAP packet to HyperRoute The CHAP packet challenges Hypertec Router to respond The challenge packet consists of an ID a random number and the host name of the remote router The required response consists of an encrypted version of the ID a secret password and the random number of the local name When the remote router or access server receives the response it verifies the secret password by performing the same encryption operation as indicated in the response and looking up the required host user name Hypertec Router and the remote router must agree on the identical secret passwords By transmitting this response the secret password is never transmitted in clear text preventin

When connecting to AT amp T SESS Custom you are provided with one telephone number directory number If you 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 This will allow you to differentiate between the two analog devices and direct calls to the correct device When connecting to National ISDN 1 you are provided with two telephone numbers directory numbers The Hypertec Router can differentiate between voice and data calls This means one telephone number can be assigned to say the telephone and the call will be directed to the correct device automatically and the other directory number assigned to say the fax machine There is no requirement for extra MSN service in this case Terminal Types When connecting to an AT amp T switch you may need to specify a terminal type to the service provider as part of the ISDN provisioning This is a letter that defines the type of device you are connecting to For the Hypertec Router the correct Terminal Type is A Information from your Service Provider Directory numbers and SPIDs In return for providing the ordering information your service provider will provide you with Directory Number s and SPID s SPIDs are not provided for the AT amp T Custom service A Directory Number is simply the address or ISDN telephone number for the ISDN line assigned by the service pro

10. Host Configuration Protocol DHCP is invented by IETF DHCP protocol works in a client server configuration One or more DHCP servers may be installed in the network A workstation running DHCP client software eg Windows 95 when configured to request IP addresses from the network will send a DHCP request to the network asking for IP address assignment In addition to assigning the IP address the DHCP server can also provide other TCP IP configuration data such as IP sub net mask default gateway IP address DNS server IP address s Hypertec ISDN 10T Router with DHCP enabled can function as a DHCP server Voice Communication Service Voice Preemption If you pick up a phone while a 2 channel data call Multilink PPP bundle is active the Hypertec Router drops one of its data links to service the voice call unless the preemption is configured as disabled An AT amp T SESS switch limitation prevents users of AT amp T Customer Multi point or Point to Point service from receiving voice calls when both data channels are in use Outgoing calls are not affected by this switch limitation because they are controlled locally at the Hypertec Router If you are using AT amp T Multi point or Point to Point service and you want to make sure that voice calls are received you should configure the link encapsulation protocol to PPP for both Internet and Intranet profile However this limits the Hypertec Router to 1 channel data calls so each data call can

12. Not all ISDN routers or access servers accept packet fragmentation To guarantee compatibility the Hypertec Router sends packets in round robin over the Multilink PPP Hypertec ISDN 10T Router can be configured to accept both round robin and fragmented packets There is a possibility of packet out of sequence when sending and receiving packet in round robin fashion Hypertec ISDN 10T Router will re order the packets when compression is enabled This will minimize the history reset request caused by the packet out of sequence The diagram above illustrates how packet fragmentation changes the way packets are transmitted between two routes When packets are send in round robin packets are sent whole across the B channels 13 Concepts and Principles of Operation Dial on Demand When the ISDN router receives packets from the Ethernet and decides to route packets to the WAN interface an ISDN call is automatically made to the remote end followed by the PPP negotiation The PPP connection to the remote router is triggered automatically by the LAN traffic without user intervention On the other hand when the traffic activity over the connection become idle for a certain period the ISDN router automatically releases the ISDN PPP connection Bandwidth on Demand If Multilink PPP is enabled the router will bring up the second B channel when the traffic activity on the first PPP channel passes beyond a certain threshold for a certain period as spe

P is the routing protocol For Intranet access IPX and bridging for other protocols e g NETBIOS may be needed occasionally Bridging A bridge automatically learns addresses of all active stations on its Local Area Network LAN It examines all the packets on the LAN reading their source and destination addresses and does not forward those packets which are intended for a local destination while forwarding all others across the WAN to the next LAN This means that traffic that is intended only for the local segment does not cross the bridge However there are some packets which a bridge must forward across the WAN to all parts of the network such as broadcasts multicasts and packets with unknown destinations to the bridge The broadcast and multicast transmission or transmission to an unknown destination may initiate an ISDN call Every ISDN call costs money Bridging is not recommended unless absolutely necessary Routing Routing is moving user data traffic across the inter network from source to destination based on the network layer address Along the way at least one intermediate router is typically encountered Routing and bridging is designed to accomplish precisely the same purpose The primary difference between the two is that bridging occurs at Layer 2 the link layer of the OSI reference model while routing occurs at Layer 3 the network layer This distinction provides routing and bridging with different information to use i
