STC-2

The Tesira STC-2 is a modular telephone interface card for use with Tesira SERVER and SERVER-IO devices. The STC-2 allows a Tesira system to connect directly to up to two standard analog telephone lines. Being more than just a normal "hybrid," each channel includes line-echo cancellation, noise suppression, caller ID decoding, ring detection/validation, DTMF decoding, and call progress tone decoding.

There is two versions of the STC-2, Version 1 and Version 2. The version of card can be identified by the text on the rear plate. Version one will indicate 'STC-2' and version 2 will indicate STC-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 STC-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 Telephone Interface Component Object. Each STC Input is also able the be associated with the DTMF Decode and Dialer blocks.
