T1 is the basic physical layer protocol used by the Digital Signal level 1(DS1)
multiplexing method in North America. A T1 interface operates at a bit rate of 1.544
Mbps and can support 24 DS0 channels. Supported DS1 standards include:
ANSI TI.107, TI.102
GR 499-core, GR 253-core
AT&T Pub 54014
ITU G.751, G.703
