General Information

The ISAR PSB 7110, ISDN Data Access Controller forms an advanced solution for ISDN applications communicating with remote ISDN as well as analog terminals. The ISAR is designed for applications on PC- or workstation platforms, but can also be used in ISDN/analog combining terminals.

It integrates two data formatting units which support binary framing, HDLC and ASYNC, which is an asynchronous data formatting according to ITU-T V.14. The data from the formatting units is than input data to a fax/modem modulation or V.110 or transparent framing towards the IOM-2 timeslots.

特性 Features

* Two universal formatter supporting ASYNC (ITU-T V.14), HDLC and binary framing of data for B-channel applications

* Bit rate adaptation according to V.110 for both B-channels (except during datamodem modulation)

* IOM-2 terminal mode (1.536 MHz), line card mode (4 MHz)

* Fax/Modemmodulation up to 14400 bps (V.32 bis, V.17) including fallback modes

* DTMF generation / detection

* 61 byte FIFO per direction for host interface communication

* External memory interface to connect external SRAM with a size of 32K x 16 for program and data

* Mailbox interface for host communication

* 3.6V power supply with separate 5V supply for interface pins

* Thin QFP-package

* Advanced CMOS technology
