The Tesira SVC-2 is a modular Voice over Internet Protocol (VoIP) card for use with Tesira SERVER and SERVER-IO devices. The SVC-2 allows a Tesira system to connect directly to IP-based telephone systems.
There is two versions of the SVC-2, Version 1 and Version 2. The version of card can be identified by the text on the rear plate. Version one will indicate 'SVC-2' and version 2 will indicate SVC-2 v2. Version 1 cards are supported by all software and firmware versions, however version 2 of the card must be used with a minimum software and firmware of Tesira v3.2 or greater.
Up to 6 SVC-2 cards are supported by each Server I/O, regardless of the version of cards. Both card types can exist within the same device, as long as the software and firmware requirements are met.
The device is supported via software using the VoIP Phone Component Object. The VoIP card is also able the be associated with the DTMF Decode and Dialer blocks.
Telnet and HTTP access to the engineering diagnostic interface can be disabled in the software from within the VoIP Property Sheet.
