Cisco MGX 8000 Series Multiservice Switch
Broadband ATM Switching Module
The Cisco MGX® 8000 Series Multiservice Switch Broadband ATM Switching Module (AXSM) can be used with the Cisco MGX 8850 PXM-45 or the Cisco MGX 8950 Multiservice Switches to deliver broadband connectivity from T3/E3 up to OC-48c/STM 16 speeds.
The class of service (Cos) queue architecture of the Cisco AXSM offers the industry's most advanced and reliable multiservice networking features. These features include Private Network-Network Interface (PNNI), switched virtual circuit/path (SVC/SVP), soft permanent virtual circuit/path (SPVC/SPVP), and Multiprotocol Label Switching (MPLS).
AXSM Ports
•
16 x T3/E3
•16 x OC-3c/STM-1
•4 x OC-12c/STM-4
•1 x OC-48c/STM-16
Key Features
•Each port is configurable for either trunk or access applications
•Each OC-48c/STM-16 delivers fully non-blocking, full-duplex through-put
•Up to 16 ATM service classes are supported
•Carrier-class implementation of standards-based PNNI, SVC/SVP and MPLS services are supported
•Large cell buffers (one million cell) help to maximize "goodput" performance during congestion
•Dynamically allocated buffers depending on connection resource needs, thereby optimizing use of system resources
•High reliability with hot-standby 1:1 AXSM card redundancy, 1:1 and 1+1 line redundancy using automatic protection switching (APS)
Key Applications
•Broadband aggregation
