General Information
Introduction
®
The PSB 2186 ISAC
-S TE implements the four-wire S/T interface used to link voice/data
terminals to an ISDN.
The PSB 2186 combines the functions of the S-Bus Interface Circuit (SBC: PEB 2080) and the
ISDN Communications Controller (ICC: PEB 2070) on one chip.
The component switches B- and D-channels between the S/T and the ISDN Oriented Modular
®
(IOM
) interfaces, the latter being a standard backplane interface for the ISDN-basic access.
The device provides all electrical and logical functions of the S/T interface, such as: activation/
deactivation, mode dependent timing recovery and D-channel access and priority control.
The HDLC packets of the ISDN D-channel are handled by the ISAC-S which interfaces them
to the associated microcontroller. In one of its operating modes the device offers high level
support of layer-2 functions of the LAPD protocol.
The ISAC-S is a CMOS device, available in a P-DIP-40, P-LCC-44, P-MQFP-64 package. It
operates from a single + 5 V supply and features a power-down state with very low power
consumption.
