CN8223 General Description
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.
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.
