Technical content
The 4 wire interface between Sub- scriber Terminals and the Network Ter- mination has been standardized by CCITT recommendation I.430. It uses a passive bus which provides separate receive and transmit loops operating at 192 Kbits/s. Two versions of TPW3852 have been designed and approved for use with the following devices: TEW3852 Siemens PEB2080 PEB2081 PEB2085 PEB2086 AMD Am79C30A TPW3852-4 Mitel MT8930A, -B, -C MT8931B, -C (See schematic below for correct connec- tions.)
