Abstract :
Describes the LT-1 connector which has been designed to provide an economical means of terminating analog transmission facilities on the No.4ESS, a digital toll switching machine. It performs a bilateral conversion between two 12-channel analog group signals in the 60-108-kHz band and a 24-channel digital digroup at 1.544 Mbits/s. In addition, signaling information in the form of a 2600-Hz tone must be converted to the digital format. The connector has been implemented with conventional per circuit technology but achieves savings compared to back-to-back channel banks.
