TPW3852 Datasheet PDF

ISDN S-Bus The 4 wire interface between Subscriber Terminals and the Network Termination 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: Input/Output Transformer TEW3852 Siemens PEB2080 PEB2081 PEB2085 PEB2086 AMD Am79C30A MT8930A, -B, -C MT8931B, -C TPW3852 TPW3852-4 Mitel (See schematic below for correct connections.)
