ICs For Communications

The PEF20550 (Extended Line Card Controller) is a highly integrated controller circuit optimized for line card and key system applications. It combines all functional blocks necessary to manage up to 32 digital (ISDN or proprietary) or 64 Analog subscribers. The switching and layer-1 control capability of the EPIC-1 (PEB 2055) constitutes a major functional block of the ELIC. For layer-2 support, two independent Special Application Communication Controllers (SACCO) are available. One typically handles the Communication with the group controller, the other is used to serve the subscriber terminals. A D-channel arbiter is employed to multiplex the HDLC controller between multiple subscribers while maintaining full duplex signaling protocols (e.g. LAPD). By Infineon Technologies Corporation
