PEF20550HV1.3 Product Details

The PEB 2055 (Extended PCM Interface Controller) is a highly integrated controller circuit optimized for analog and ISDN line card and central switches applications. The EPIC-1 provides the circuitry necessary to manage up to 32 digital (ISDN or proprietary) or 64 analog subscribersThe EPIC-1 is dedicated to switch PCM data between two serial interfaces, the system interface (PCM interface) and the configurable interface (CFI). The EPIC-1 performs non-blocking time and space switching for up to 128 channelsSince the system cost of the EPIC-1 is divided by the number of lines it controls, ar highly economical implementation of digital or analog subscriber lines can be performed The EPIC-S (PEB 2054) is a pin compatible device offering half the switching capacity of the EPIC-1. Therefore the EPIC-S is capable of handling up to 16 ISDN or 32 analog subscribers. It is programmable according to the EPIC-1 with respect of the pins not available.The EPIC is implemented in a Siemens advanced CMOS-technology and manufactured in a P-LCC-44-1 package.The EPIC is member of a chip family supporting a highly economical implementation of line cards and subscriber terminals.
