The ISDN Single-Chip NT1 offers the most cost-effective solution
for the design of Network Termination Equipment. It has a flexible
interface, making it compatible with other NXP® ISDN components.
When combined with Our controller
family, the MC145576 becomes the heart of a powerful and
cost-effective Smart NT1 solution.
The MC145576 integrated NT1 fully complies with the appropriate
USA and European recommendations for the U-interface -- ANSI T1.601
1992, ETSI ETR 080, FT CS3211 in NT mode -- and the S/T-interface --
ITU I.430, ANSI T1.605, ETSI ETS 300 012 in NT mode.
The U-interface uses 2B1Q line coding. The device offers both GCI
and IDL/SCP interfaces for compatibility with previous designs based
upon the MC145574A S/T-Interface
Transceiver and the MC145572 U-Interface
Transceiver chip set. The SCP serial interface allows connection
to the extensive family of NXP controllers.
When combined with a member of the
MC68302 family of multiprotocol controllers, MC145484
PCM codec, and an analog line interface (SLIC), the MC145576
enables optimal design of a Smart NT1 or a Smart Terminal Adapter
(U-interface based TA with an S/T bus access). The same architecture
can be used with a second codec and SLIC to allow for a dual analog
