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.

The controller part, DELIC, is available in two different versions:

• DELIC-LC (PEB 20570) is a line card controller providing voice channel switching,

multiple HDLC and layer-1 control for up to three VIPs (24 ISDN channels). Other

transceiver ICs (32 analog or 16 digital channels) may additionally be connected via

IOM-2/GCI interface.

• DELIC-PB (PEB 20571) additionally provides a programmable telecom DSP

including program and data RAM. This DSP can be used for layer-1 control, protocol

support and signal processing. The flexibility gained by the programmability allows

Infineon to offer different application specific solutions with the same silicon just by

software configuration.

A configuration tool assists the user in finding a valid system configuration. Even more

customer specific DSP-routines can be integrated with the assistance of Infineon.

The transceiver part, VIP, is available in two different versions:

• VIP PEB 20590 is the first (8 channel) ISDN transceiver that implements multiple UPN

and S/T interfaces within one device. The user can decide by programming in which

mode a desired channel shall work.

A total of 8 channels are provided for layer-1 subscriber or trunk line characteristic.

The VIP is programmed by the DELIC via the IOM-2000 interface. VIP’s eight

channels are programmable in the following maximum partitioning between UPN and

S/T channels:

combination of UPN S/T interface (i.e. each of the 8 channels may be programmed to

S/T or UPN mode)
