Trilithic's Virtual Controller is used to replace channels at a cable systems' remote hubs-sites.

In conjunction with an EAS Channel Demodulator, Virtual Controller provides all the EAS signals available from the Trilithic primary controllers to replacement technology at remote locations. The Virtual Controller is a "slave" device to the controller located at the primary headend. The Virtual Controller is an addressable device (254 possible addresses), although this particular option is rarely used and is capable of ignoring instructions not specifically meant for it.

Due to "Must Carry" laws, local television and government stations are required to be available to the cable TV subscribers, and additionally, franchise agreements often require a Telephone Voice Access to be transmitted to local subscribers. This means that local channels and voice must be inserted at the hub-site locations. It does not however, alleviate the responsibility of the cable aystem to insert EAS messaging on these remote channels.

The Virtual Controller provides RS-232 data to an RS-232 to RS-485 converter located inside the EDS-1 product. This converter, in turn, provides data to an AFSK device also residing in the EDS-1. When data is fed to the AFSK device, along with the appropriate RS-232 control lines, the program audio on the EAS Channel is temporarily interrupted by a 9600 Baud audio carrier. This EAS channel audio is then simultaneously sent out to subscribers, and to the remote hub-Sites.
