Using utorate Renegotiation, it dynamically adjusts operating rates to compensate for switched network line impairments, for superior performance, even over P circuits that may vary in quality. You can use the public network to support high speed applications (e.g., remote L or nternet access) that in the past would have required more reliable, but often less economical, dedicated links. 6FH#QG#)H[LH#&RQQHFWLYLW\ he SC ual V.34 modem is a 7-inch by 9.5-inch (178 mm by 41 mm) printed circuit card that conforms to GC s SpectraComm format (Figure 1). s part of the Spectra- Comm family of products, S-compliant SC ual V.34 installs in any GC shelf or enclosure: the -slot SC000 shelf or, for higher density applications, the 16-slot SC5000 shelf. For standalone, non-s CP applications, the modem installs just as easily in the single-slot Spectra- Comm or C standalone enclosures. his Spectra- Commonality makes a manageable, scalable environment that accommodates your network s needs.

%XLW0LQ#6HFXULW\#)HWXUHV SpectraComm V.34 modems supply a variety of built-in security features for dial-in users. With the built-in Stead- Fast Handshake Security enabled in SC V.34 modems at both the originating and answering sites. s part of its handshake, the answering GC modem sends the originating GC modem a cell password that must have been previously stored in both modems. GC's SteadFast Handshake Security is hacker-proof and will not permit unknown modems to communicate (Figure ). With the built-in SteadFast n-line Password security, the SC V.34 modem is configured with stored cell passwords (Figure ) to respond to dial-in users as follows: With Callback Security, after accepting the online password, the modem disconnects and calls back the originating modem. With Roving Callback, after accepting the online password, the V.34 modem prompts the caller for a callback phone number. With Cell Callback, after accepting the online password, the modem prompts the caller for a memory cell number, disconnects the call and then places a return call using the phone number stored in that cell. SWLRQ#$XWKHQWLFWLRQ#)#(QFU\SWLRQ GC modems can employ RUS (Remote uthentication for ial-n Users) to authenticate users from a secure and centralized database of RUS usernames, passwords and challenges. RUS uthentication will accept, challenge and reject dial-in users via secure RUS servers. he RUS ccounting feature offers call tracking and billing information. With the S ncryption option, the modem encrypts async data sent across the communications facility via a dialup or leased line connection. wo GC modems optioned for data encryption are required at either end of the link. he modems perform all data encrypt/decrypt functions without burdening customers' applications, and without the need of purchasing additional hardware.

SWLRQ#6HFXUH#$FFHVV#&RQWUR he Secure ccess Controller (SC) system consists of secure servers and a factory--optioned GC V.34 modem that authenticate remote users attempting to access protected network equipment, such as switches, routers, multiplexers, etc. he uthentication Server generates the private key exchanged by the modem and server, and the public key exchanged by the modem and remote user s client software. ach connection sets up a secure tunnel that passes S-encrypted data to the authorized user. When a user terminates a management session, the Secure ccess odem requests a connection to the uthentication Server to obtain another new private key, thus preventing further access from the previous remote user or intruders. he Secure ccess odem is user-configured via extended commands typed at one of its management interfaces (elnet via the SC, the SC craft port, or a terminal connected to the modem s connector). Figure 3 demonstrates a typical network configuration and the authentication sequence that occurs when a remote user attempts a management connection to protected network equipment. $XWKHQWLFWLRQ#6HXHQFH 1. he Secure ccess odem obtains a new private key from the uthentication Server via a secure tunnel at every powerup, reset, key timeout, or session end.. Remote users make a connection to the uthentication Server through the P via a modem. he remote user employs client software to request a connection to the Secure ccess odem. his involves contacting the uthentication Server to check the user's and password, and then initiating a client software connection with the requested Secure ccess odem. nce the remote user is authenticated as a trusted user, the uthentication Server transfers the necessary connection data and a public key to the client software and disconnects from the user. 3. he client software then calls the Secure ccess modem and performs a public key exchange over a secure tunnel via the P. 4. he authorized user is allowed encrypted and authenticated management access to the appropriate protected network equipment using S data encryption.
