Product Summary
The PEB2054N (Extended PCM Interface Controller) is a highly integrated controller circuit optimized for analog and ISDN line card and central switches applications. The PEB2054N provides the circuitry necessary to manage up to 32 digital (ISDN or proprietary) or 64 analog subscribers. The PEB2054N is dedicated to switch PCM data between two serial interfaces, the system interface (PCM interface) and the configurable interface (CFI). The PEB2054N performs non-blocking time and space switching for up to 128 channels.
