Channels T-7 through T-14 are sub-band channels and are not used for normal television channel distribution. These channels are used for sending video back to the cable television headend, such as by public-access television stations on a cable tv system.
Cable channels 2 through 13 operate on the same frequencies as broadcast television (the VHF band).
Channels 100 to 125 can be used by analog cable systems, but frequency allocation is often inconsistent and not all televisions and VCRs can pick them up.
Digital cable channels are often numbered starting at 100 or 200, but these are virtual channel numbers and do not correspond to particular frequencies.

In North America, terrestrial television is broadcast on designated channels numbered 2 through 69.
Traditionally, the frequencies are divided into two sections, the very high frequency (VHF) band and the ultra high frequency (UHF) band, but in reality, the VHF band is further subdivided into two more sections, VHF-Lo (band I) and VHF-Hi (band III).
Channels 14 through 19 are used for two-way radio in major cities, intended for use on a non-interference basis, although the transition to digital television (DTV) has caused problems in certain instances when a previously unused channel has begun to be used for DTV broadcasts.
