ATM Transmitter/Receiver with UTOPIA Interface

The CN8223 ATM Transmitter/Receiver with UTOPIA Level 1 interface provides a

single-access ATM service termination for User-to-Network (UNI) and

Network-to-Network Interfacing (NNI) in conformance with ATM Forum UNI and NNI

Specification 94/0317; Bellcore Specifications TR-TSV-000772, TR-TSV-000773,

TR-NWT-000253, and T1S1/92-185; ITU Recommendations I.432, G.707, G.751,

G.832, and Q.921; and ETSI prETS 300 213 and 300 214. Both Customer Premise

Equipment (CPE) and switching system interface functions are provided. The CN8223

provides DS1, E1, DS3, E3, E4, STS-1, and STS-3c (and STM-1) ATM cell alignment

functions. The system interface is via a parallel FIFO port or UTOPIA interface. In

addition, the CN8223 terminates the operations and maintenance flows F1, F2, and F3.

The CN8223 provides four FIFO port interfaces and one UTOPIA interface. Each

receiver port can be programmed with a particular Virtual Channel Identifier/Virtual

Path Identifier (VCI/VPI) address for message routing. VCI/VPI pages can also be

selected via masking registers.

Distinguishing Features

•

Integrates 7 line framers with ATM

layer processing according to ATM

Forum UNI and NNI Specifications

•

UTOPIA Level 1 interface

Internal framers for DS3, E3 (G.751,

G.832), E4 (G.832), STS-1, STS-3c,

STM-1

•

PLCP and G.804 HEC cell alignment

for all data rates from 1.544 Mbps to

155 Mbps

Direct interface to TAXI^TMor external

T1/E1 framers

•

ATM and SMDS cell modes

4 FIFO ports with header screening,

formatting, and transmit priority

controls

The microprocessor can set control registers for insertion of selected header fields

by the transmitter on an individual port basis. The microprocessor can also control

insertion of all overhead and can insert errors in selected fields for test equipment

applications.
