Administration of Plus Products via PPP |
Definition |
| You can use HiPath 3000 to administer Plus Products from a central service center. HiPath 3000 merely provides the transmission medium for this. The actual Plus Product administration is performed via special software programs, such as pcANYWHERE. |
| HiPath 3000 is addressed from the service center via its PSTN (public switching telephone network) interface. The Plus Products connected to a LAN can be reached via the HiPath 3000's LAN interface. HiPath 3000 In this case, acts like a router. |
| You must enter a router call number (DID number) for every PSTN interface in the service center for external access to HiPath 3000. |
|

|
| You can establish a connection between the Plus Product and the service center via the integrated digital modem (B channel) or the integrated analog modem (IMODC). The point-to-point protocol (PPP) is used in both cases for data exchange. |
|
Access Mechanism |
| A list of up to twenty remote structures controls access from the service center to the customer LAN and vice versa. Each remote structure contains the following information: |
| • | The IP address of the service center (= PSTN partner in the service center) for setting up connections from the customer LAN to the service center and for the automatic transmission of error messages (SNMP traps). |
| • | The DID number (part of the numbering plans) for direct identification of this remote structure. |
| • | Up to five PSTN remote numbers marked as incoming (for identifying the remote structure - when dialing the router call number) and/or outgoing (for use as callback address). |
| • | Short hold mode yes/no |
| - | If "Short hold = yes" is selected, an inactive PSTN connection is set up after a configured time (short hold time). If there are new data packets to be transmitted, the connection is set up once again (transparent for the user). This mechanism is also known as background connection setup or cleardown. Costs are only incurred when the line is actually used. |
| - | If "Short hold = No" is selected, a PSTN connection remains permanently active until the end criterion is received. |
| • | Short hold (sec.) This parameter describes the length of time in seconds after which an inactive PSTN connection is cleared down. |
| • | Callbk Yes/No |
| - | If "Callbk = Yes" is selected, a connection request is first of all denied. Then the first station number marked as outgoing in the remote structure found is called back. Three attempts are made to set up the connection, then the next outgoing station number is used. The system stops trying to set up the callback after three unsuccessful attempts. |
| - | If "Callbk = No" is selected, the connection is set up immediately. |
| • | Remote analog modem If you select "Yes", the V.34 protocol in the B channel is used for an outgoing connection via the ISDN line. |
| • | IP mapping Yes/No If a number of different customers have the same IP address, you can use address mapping to achieve unique IP address assignment in the various customer LANs. |
| - | If "IP mapping = Yes" is selected, you can map an IP address which is assigned to multiple customers to a unique "virtual" IP address. You can perform IP mapping for up to twenty address entries. |
| Examples: IP data transfer from the customer LAN to the service center via the PSTN interface: IP customer LAN is transformed by HiPath 3000 into an IP virtual LAN. IP data transfer from the service center to the customer LAN via the PSTN interface: IP virtual LAN is transformed by HiPath 3000 into an IP customer LAN. |
| - | If "IP mapping = no" is selected, IP address mapping is not available. |
| • | Security mechanisms for connection setup Use the PAP (PPP authentication protocol) and/or CHAP (challenge-handshake authentication protocol) to determine whether, |
| - | the Plus Product (client) must be authenticated at HiPath 3000 (host) or |
| - | the HiPath 3000 (host) must be authenticated at the Plus Product (client). |
| Authentication is based on the user ID and the password. |
