T1C (T1 Concatenated)

Corresponds to DS-1C (Digital Signal level One Concatenated) in the

North American digital hierarchy.T1C links together two T1s to run at a signaling rate of 3.152 Mbps in support of 48 DS-0 channels.T1C runs at twice the signaling rate and supports twice the number of channels as T1, but with the same repeater spacings as T1.T1C was not deployed widely and is considered obsolete. See also concatenation, DS-0, DS-1C, repeater, T1, and T-carrier.
