The Softel
SE3048 is a 2U rack mounted unit designed to provide
up to 16 TV lines of teletext data compliant with
EBU, WST and CCIR specifications for the transmission
of teletext pages and data broadcast.
The SE3048
is offered by Softel on both Vortex and Cyclone teletext
management systems as the output device for teletext
broadcast, and is designed to hold a copy of the teletext
