Note that when a T-carrier system is used as in North America, robbed bit signaling can mean that a DS0 channel carried over that system is not an error-free bit-stream.
This is equivalent to using a non-linear ADC as in a T-carrier telephone system that implements A-law or μ-law companding.
T-carrier spans are terminated, originally one per card but in later models usually two, in Digital Line Trunk Units (DLTU) which concentrate their DS0 channels into the TSI.
When carried over copper wire, this is the well-known T-carrier system, with T1 and T3 corresponding to DS1 and DS3, respectively.
Comparison of T-carrier and E-carrier Note 1: The DS designations are used in connection with the North American hierarchy only.
Frame Relay can run on fractional T-1 or full T-carrier system carriers (outside the Americas, E1 or full E-carrier ).
