Overview
The PEB 20550 (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).
Additionally, typical line card glue logic functions such as a power-up reset generator, a
watchdog timer and two parallel ports are integrated.
The ELIC is implemented in a Siemens advanced 1.0-µm CMOS-technology and
manufactured in a P-MQFP-80-1 package.
The ELIC is a member of a new chip family supporting D-channel multiplexing on the line
card and in the subscriber terminal. This concept allows an highly economical
implementation of digital subscriber lines.
