A T1 line speed refers to the speed at which a T1 line is able to transfer data., often written in kilobytes per second. T1 lines these days see less use and have been replaced with fiber optics.
T1 line
The purpose of a line-side T1 is to directly connect two devices, using a T1, without going through a service provider. This is done in lieu of using analog circuits or if IP connectivity/trunking is not available. For example, a fax server can connect directly to a corporate PBX, via a line side T1, using a cross-over 2-pair, 22 AWG shielded twisted pair cable. This is a direct connection from the PBX's T1 card to the fax server's T1 card. Provisioning of the T1 circuit is done in both the PBX and the fax server to accommodate the medium (24 channels, robbed-bit signaling).
A T1 line provides you with 1.544Mbits per second, full duplex. Full duplex means that, you get the 1.544Mbps in up- and download direction. 1.544 Mbit per second equals 0.192MByte per second.
