Product Details

Description

Features:

The DOC provides all necessary features for building
PBX (Privat Branch eXchange) systems and Line
Cards.
• In the PBX mode (Figure 2-1), the DOC provides:
6 fully usable IOM-2 (GCI) interfaces and thus it can control up to 48 ISDN or 96 analog subscribers.
4 PCM highways with 128 time-slots in total.
• In the Line Card mode (Figure 2-3), the DOC provides:
2 fully usable IOM-2 interfaces with 16 IOM-2 subframes (2 * 8) and
2 limited IOM-2 interfaces, as two DSP ports are connected, and thus it can control 16 to 24 ISDN (or 32 to 48 analogue) subscribers.
4 PCM highways with 256 time-slots in total.
• Signaling via 8 assignable HDLC controllers, each with a 64-byte data FIFO for transmit and for receive direction.
2 HDLC controllers (SACCO-A) assignable to two of up to 48 ISDN subscribers at a time via two different D-channel Arbiters
4 HDLC controllers (SIDEC) assignable to any D-/B-channel in data upstream or data downstream direction on four IOM-2 interfaces.
2 HDLC controllers (SACCO-B) assignable to any time-slot in data upstream or data downstream direction of the four IOM-2 interfaces or the PCM highways. Optionally, both controllers can be used as stand alone HDLC controllers with up to 8.192 Mbit/s transfer rate. They support DMA operation.
• On-chip user programmable 16-bit Digital Signal Processor, OAK®, (with 20, 30 or up to 40 MIPS) with access to 64 time-slots (via one or two internal IOM-2 interfaces) for DTMF/Tone generation and recognition, conferencing, music-on-hold, modem emulation, etc.
1 K * 16-bit on-chip data memory (X)
512 * 16-bit on-chip data memory (Y)
DSP proprietary interface to an external memory:
* Program memory up to 56 K * 16-bit
* Data memory up to 32 K * 16-bit
On-chip program ROM (Boot) ~ 0.5 K * 16-bit
• a-/µ-law coding and decoding by hardware (on the fly)
• Firmware for DSP work load measurement (within every 125 µs frame)
• Protection against write into program memory using password
• µP-DSP communication via two Mail-Boxes
• On-chip emulation (OCEM®) for DSP program debugging
• 8-bit µP Interface compatible with Siemens/Intel bus schemes
• Programmable clock generator with built-in logic for Master and Slave configurations
• Watch-Dog timer
• Reset logic
• UART for V.24 Interface
• Multifunctional Input/Output Port configurable as a general I/O Port, DMA lines for SACCO-B0 or as additional UART lines for Modem connection
• Integrated Interrupt controller with vector generation and support for DOC cascading
• Interrupt vector handling compatible with Siemens/Intel/Motorola bus schemes
• Up to 4 external interrupt inputs (via the general I/O Port)
• JTAG Interface for on board tests
• Interface for HW and SW DSP evaluation (debugging)
• Advanced CMOS 0.5 µm technology
• 3.3-V and 5-V Power Supply in 5-V environment 3.3-V Power Supply in 3.3-V environment
• TTL driving capability, TTL and CMOS compatible inputs
• P-MQFP-160 package
