PEB20550規(guī)格書詳情
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.
Features
Switching (EPIC?-1)
? Non-blocking switch for 32 digital (e.g. ISDN) or 64 voice subscribers
– Bandwidth 16, 32, or 64 kbit/s
– Two consecutive 64-bit/s channels can be switched as a single 128-kbit/s channel
? Freely programmable time slot assignment for all subscribers
? Synchronous μP-access to two selected channels
? Two types of serial interfaces independently programmable over a wide data range (128 - 8192 kbit/s)
– PCM-interface
Tristate control signals for external drivers
Programmable clock shift
Single or double data clock
– Configurable interface
Configurable for IOM-, SLD- and PCM-applications
High degree of flexibility for datastream adaption
Programmable clockshift
Single or double data clock
Handling of Layer-1 Functions (EPIC?-1)
? Change detection for C/I-channel (IOM-configuration) or feature control (SLD-configuration)
? Additional last-look logic for feature control (SLD-configuration)
? Buffered monitor (IOM-configuration) or signaling channel (SLD-configuration)
Handling of Layer-2 Functions (SACCO)
? Two independent full duplex HDLC-channels
– Serial interface
Data rate up to 4 Mbit/s
Independent time slot assignment for each channel with programmable time slot
length (1-256 bits)
Support of bus configuration with collision resolution
Continuous transmission of 1 to 32 bytes possible
– Protocol support
Auto-mode, fully compatible to PEB 2050 (PBC) protocol
Non-auto mode, address recognition capability
Transparent mode, HDLC-framing only
Extended transparent mode, fully transparent without HDLC-framing
– 64-bytes FIFO’s per HDLC-channel and direction
D-channel Multiplexing (D-channel arbiter)
? Serving of multiple subscribers with one HDLC-controller
? Full duplex signaling protocols (e.g. LAPD or proprietary) supported
? Programmable priority scheme
? Broadcast transmission
Line Card Glue Logic
? Power-up reset generator
? Watchdog timer
? Parallel ports (8-bit input, 4-bit I/O)
Boundary Scan Support
? Fully IEEE 1149.1 compatible
? 32-bit device identification register
Bus Interface
? Siemens/Intel or Motorola type μP-interface
? 8-bit demultiplexed bus interface
? FIFO-access interrupt or DMA controlled
