T1 over video

When WHTM-TV-Harrisburg, Pennsylvania decided to transmit in digital audio, its station transmission link (STL) needed modification. In order to meet the need of sending stereo right and left audio, SAP audio, PRO audio, and ENG telemetry from the studio to a microwave transmitter, WHTM-TV needed 4 to 6 subcarriers on its STL. Intraplex manufactures digital T1 multiplexers and audio, voice and data modules. WHTM-TV uses a microwave signal that only uses part of the baseboard signal. Intraplex allows it to add audio, voice, and data channels into the remaining baseboard signal by multiplexing. WHTM was impressed with the product and the support service of Intraplex.
