    RIP over WAN links. The active route is advertised by Hypertec Router via RIP (if enabled) on its LAN interface. For the Hypertec ISDN router, the default route created by the system is automatically set toward Internet remote router. Users need to enter static route entries only when there are multiple subnets at the Intranet remote end.

  • Page 17: Dynamic Ip Address Assignment

    You can set Hypertec Router IP addresses to be 'un-numbered' or ‘numbered’. By setting it to “un- numbered”, you can route IP over a link between two devices without assigning IP addresses to the ISDN interfaces. This allows you to save valuable IP address space. There are situations where a traditional “numbered”...

  • Page 18: Ipx Address

    If a Netware server is not locally connected to the client’s network, the router connecting to the client’s network is responsible for responding to the “find nearest server” request. A router such as Hypertec ISDN 10T Router learns of the existence of a remote server by manual configuration, and through Service Advertising Protocol (SAP).

  • Page 19: Ipx Spoofing

    Netware Servers such as file servers use SAP protocols to advertise their service throughout the network. A router such as Hypertec ISDN 10T Router listens to the SAP packets from servers to learn what services are available in the local network. Routers also exchange SAP packets so that the router can learn what services are available at the remote networks.

  • Page 20: Multilink Ppp

    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 means that the volume of data has reached the percentage value that you have set on “1->2 util”. You can configure Hypertec Router to wait for a set length of time before bringing the second B-channel into operation. In this case, data volume must exceed 80% volume for a certain length of time, as in “ave interval”...

  • Page 22: Data Compression

    Calling Line Identification (directory number) of the device which has just called you, or the Calling Line Identification (CLID) may not be passed to the Hypertec Router . You may want to disable CLID authentication, instead, use the Challenge-Handshake Authentication Protocol (CHAP) for additional security if these circumstances apply.
  • Page 23 It is convenient in the sense that, the users don’t have to change the private legacy IP addressed already in use. In order for the outside world to access the TCP/IP servers on the LAN, the Hypertec Router allows a list of internal IP addresses to be associated with FTP, Telnet, HTTP, and Email servers. Traffic destined for the list servers are forwarded to the specified IP addresses.

    EZ-ISDN codes mirror some of the Capability Packages described previously. They are another method of ordering the correct ISDN service. In addition, to simplify the process of provisioning an ISDN line, the Hypertec Router complies with and is registered against EZ ISDN-1. You should ask your ISDN service provider for EZ ISDN-1 provisioning.

  • Page 28: Multiple Subscriber Numbering (Msn)

    MSN allows multiple telephone numbers to be assigned to a single BRI connection. This allows you to assign specific numbers to specific devices. For the Hypertec Router, there will be one LAN connected and one or two analog devices (e.g. telephone, fax). It is possible to give each device a separate number through multiple subscriber numbering, allowing calls to be routed to the correct analog device.
