Standards Compliance


This appendix lists the relevant technical and compliance specifications for Release 4 of the Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830 PNNI controllers, PNNI, and ATM switched virtual circuits in the following sections:

PNNI Compliance

ATM Signaling Compliance

Processor Switching Module Specifications

UNI 4.0

AINI 3.0 and 3.1


Note This appendix is not a comprehensive list of all the standards that are supported on the Release 4 PXM45 and PXM1E based switch. To verify the support of a specific standard that is not listed in this appendix, please contact your Cisco account representative.


PNNI Compliance

The PXM45 and PXM1E based PNNI routing software was designed to be compliant with 1 below. The software supports robust topology convergence, dynamic and QoS based routing in hierarchical ATM networks with scalability from small to very large networks.

Other specifications to which the PNNI routing conforms are as follows:

1. ATM Forum, "PNNI Specification Version 1.0," af-pnni-0055.000, March 1996

2. ATM Forum, "PNNI V1.0 Errata and PICS," af-pnni-0081.000, March 1997

3. ATM Forum, "Interim Inter-switch Signaling Protocol (IISP) Specification Version 1.0," af-pnni-0026.000, December 1994

4. AINI

5. PNNI v2.0 draft

6. Path and Connection Trace
