Apparatus and method are provided which map E1 signals into a logical space of a predetermined number of DS1 signals. 24 selected DS0 signals that are part of each E1 signal are mapped into the space of one DS1 signal in the logical space. The remaining eight DS0 signals of every three E1 signal are then interleavingly mapped into the space of one DS1 signal in the logical space. Depending on the defined logical space, additional E1 signals are mapped into the logical space in the same manner until the predetermined number of DS1 signal spaces in the defined logical space are filled.

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).

A telecommunication system (10) includes one or more subscribers (24) that provide telecommunication traffic in an upstream direction to a D4 channel bank (26). The D4 channel bank provides network interface signals having a first signaling protocol format to a cross-connect (18) over a telecommunication link (28). The cross-connect (18) includes a signaling protocol converter (30) that converts network interface signals having the first signaling protocol format into network interface signals with a second signaling protocol format. The cross-connect (18) passes the network interface signals with the second signaling protocol format to a local digital switch (20) over any of multiple telecommunication links (22a-22n). In a downstream direction from the local digital switch (20) to the subscribers (24), the signaling protocol converter (30) converts from the second signaling protocol format to the first signaling protocol format. In this manner, devices with differing signal protocol formats may communication with each other.

Apparatus for redundancy circuit protection includes a controller (20), a plurality of circuits (22) coupled to the controller (20), and a redundancy switch (50) coupled between the plurality of circuits (22) and a network. The redundancy switch (50) is adapted for connecting or disconnecting selected ones of the plurality of circuits (22) to or from the network. In addition, a predetermined number of spare circuits (52) with similar functionality as the plurality of circuits (22) are coupled to the high density bank control unit (20), so that the redundancy switch (50) may connect or disconnect selected ones of the predetermined number of spare circuits (52) to the network and establish a transmission path from the controller (20) through the selected spare circuits (52) to the network.
