Introduction
The DELIC and VIP chipset realizes multiple ISDN S/T and UPN interfaces together with controller functionality typically needed in PBX or Central Office systems. This functionality comprises voice channel handling, signaling control, layer-1 control, and even signal processing tasks.
Moreover it provides a programmable master/slave clock generator with 2 PLLs, an universal µP interface and a DMA interface.

DELIC-LC Key Features
DELIC-LC is optimized for line card applications:
• One IOM-2000 interface supporting three VIPs i.e. up to 24 ISDN channels
• Two IOM-2 (GCI) ports (configurable as PCM ports) supporting up to 16 ISDN channels or 32 analog subscribers
• Four PCM ports with up to 4 x 2.048 Mbit/s (4 x 32 TS) or 2 x 4.096 Mbit/s or 1 x 8.192 Mbit/s
• Switching matrix 256 x 256 TS (8-bit switching)
• 24 HDLC controllers assignable to any D- or B-channel (at 16 kbit/s or 64 kbit/s)
• Serial communication controller: high-speed signaling channel for 2.048 Mbit/s
• General purpose I/O ports
• Standard multiplexed and de-multiplexed µP interface: Infineon, Intel, Motorola
• Programmable PLL based Master/Slave clock generator, providing all system clocks from a single 16.384 MHz crystal source
• JTAG compliant test interface
• single 3.3 V power supply, 5 V tolerant inputs

DELIC-PB Key Features
    Compared to the DELIC-LC, having a fixed functionality, the DELIC-PB provides a high degree of flexibility (in terms of selected number of ports or channels). Additionally it features computing power for typical DSP-oriented PBX tasks like conferencing, DTMF etc.
    A Microsoft Windows based configuration tool, the Configurator, enables to generate an application specific functionality. Its features are mainly determined by the firmware of the integrated telecom DSP.
