Steve and the group:

It is still in the rules. Control has been broadened beyond a control 
radio to include fiber optic, telco, and wireline (to include internet). 
the radio can be any amateur frequency now, no longer required to be 
above 220 MHz.I believe you are referencing line (b):

§97.213 Telecommand of an amateur station.
An amateur station on or within 50 km of the Earth's surface may be 
under telecommand where:
(a) There is a radio or wireline control link between the control point 
and the station sufficient for the control operator to perform his/her 
duties. If radio, the control link must use an auxiliary station. A 
control link using a fiber optic cable or another telecommunication 
service is considered wireline.
(b) Provisions are incorporated to limit transmission by the station to 
a period of no more than 3 minutes in the event of malfunction in the 
control link.
(c) The station is protected against making, willfully or negligently, 
unauthorized transmissions.
(d) A photocopy of the station license and a label with the name, 
address, and telephone number of the station licensee and at least one 
designated control operator is posted in a conspicuous place at the 
station location.
