Abstract
An interface unit (12) for interfacing a digital loop carrier (16) to a digital cross-connect (14) comprises a control interface (22) coupled between the digital cross-connect (14) and digital loop carrier (16) for conversion and communication of control messages therebetween. A timing interface (32) is further coupled between the digital cross-connect (14) and digital loop carrier (16) for generally synchronizing the operations thereof. Further, a matrix interface (30) is coupled between the digital cross-connect (14) and digital loop carrier (16) for converting data rates and formats of data in the digital cross-connect (14) and digital loop carrier (16), so that network signals received by the digital loop carrier (16) are converted from a first format to a second format and communicated by the matrix interface (30) to the digital cross-connect (14) for cross-connection, and cross-connected data are converted from the second format to the first format and communicated to the digital loop carrier (16).
