It is a [[User–network interface]] [[Integrated_Services_Digital_Network#Reference_points|reference point]] that is characterized by a four-wire, 144 [[kilobit|kbit]]/s (2B+D) user rate.<br /> <br /> Other characteristics of a T-interface are:<br /> * it accommodates the [[link access]] and [[transport layer]] function in the ISDN architecture<br /> * it is located at the user premises<br /> * it is distance sensitive to the servicing [[Network termination 1]]<br /> * it functions in a manner similar to that of the [[Channel service unit]]s (CSUs) and the [[Data service unit]]s (DSUs).&lt;ref name=&quot;FS1037C&quot;&gt;{{FS1037C}}&lt;/ref&gt;<br /> <br /> The T interface is electrically equivalent to the [[S interface]], and the two are jointly referred to as the S/T interface.&lt;ref name=&quot;ralphb&quot;&gt;{{cite web |url=http://www.ralphb.net/ISDN/ifaces.html |title=ISDN Tutorial: Interfaces |last=Becker |first=Ralph |work=ralphb.net |access-date=2014-01-22 |date=2006-12-05}}&lt;/ref&gt;<br /> <br /> ==See also==<br /> * [[R interface]]<br /> * [[S interface]]<br /> * [[U interface]]<br /> <br /> ==References==<br /> {{Reflist}}<br /> <br /> [[Category:Networking hardware]]<br /> [[Category:Integrated Services Digital Network]]<br /> <br /> <br /> {{compu-hardware-stub}}</div>
