Serial interface and T1 controller OSI model

Hello,

Where does the serial interface and T1 controller fall under the OSI model.  Also does the VWIC have several controllers and serial interfaces or is it one T1 controller per VWIC as well as serial interface?

A serial interface and the T1 controller are involved in sending physical signals over the wire so they are involved in layer 1 of the OSI model. The serial interface more so than the T1 controller are involved in encapsulating the data for transmission over the wire so they are involved in layer 2 of the OSI model. The serial interface and the T1 controller do not do any processing (or have any understanding)of IP addressing so they are not involved in layer 3 or any other higher layers of the OSI model.
