Summary of AUSM Features
The ATM Universal Service Modules (AUSM) include the following features:
• ATM UNI with high port-density for the CPE—with AUSMs in all 8 service module slots, an
MGX 8230 shelf can support up to 64 individual T1 or E1 lines. An individual card set can support
1000 data connections and 16 management connections.
• Inverse multiplexing for ATM (IMA) that complies with ATM Forum v3.0 and v3.1—the 8-port
AUSM can provide N x T1 or N x E1 logical ports up to maximum rates of 12 Mbps for T1 or
16 Mbps for E1.
• Classes of Service—CBR, ABR, non-real-time VBR, real-time VBR, and UBR with per-VC
queuing on ingress and multiple Class-of-Service queues on egress. ABR includes support of both
ForeSight ABR and standard ABR (TM 4.0 compliant).
• Statistics collection.
• Virtual path connections (VPCs).
• Network synchronization derived from one of its lines.
• Bit error rate test (BERT) functionality with loop back pattern generation and verification on
individual lines or logical port. For a description of the BERT functions, see the section titled “Bit
Error Rate Testing Through an MGX-SRM-3T3.”
• 1:N redundancy through the optional MGX-SRM-3T3/C card.
• Automatic card-restore.
• SNMP and TFTP to support card and connection management.
• Resource partitions for individual network control applications.
