Remote administration 
 
You can administer multiple HiPath 3000/5000 systems from a central service center via PPP (point-to-point protocol). Each HiPath 3000/5000 is addressed via its PSTN (public switching telephone network) interface.
You must enter a router call number (DID number) for every PSTN interface in the service center for external access to HiPath 3000/5000. This call number is not the number previously used for administration via integrated digital modem (B channel) or integrated analog modem (IMODN).
You can establish a connection between the service center and HiPath 3000/5000 using either the integrated digital modem (B channel) or the integrated analog modem (IMODN). Data is exchanged in both cases using Point-to-Point-Protocols (PPP).
If the connection is established via callback, HiPath 3000/5000 first of all denies a connection request from the service center (HiPath 3000/5000 Manager E). A callback is then set up to the service center's calling party number transferred via the PSTN connection's D channel.

SIRA Environment  
In a SIRA (Secured Infrastructure for Remote Access) environment, HiPath 3000 can be monitored and administered via a secure connection. Among other things, virtual terminal servers, specific service applications (e.g., HiPath 3000/5000 Manager E), and database servers are part of a SIRA environment.
HiPath 3000/5000 Manager E offers a CAPI interface (Common ISDN Application Programming Interface) for remote administration via ISDN. In a SIRA environment, HiPath 3000/5000 Manager E runs on a Windows terminal server and can establish connections to multiple specified controllers (Bintec® routers) via the ISDN interface ("Remote Multi-CAPI" feature). If the callback function is active in HiPath 3000/5000, a callback to the defined controller in the service center on the second B channel to the ISDN multiple subscriber number is performed after the connection request has been rejected.
