ATM Universal Service Module
The eight-port ATM Universal Service Module (MGX-AUSM/B-8T1 and MGX-AUSM/B-E1) is a
multipurpose card set with eight T1 or E1 lines that support:
• ATM UNI with high port-density for the CPE—with AUSMs in all 24 service module slots, an
MGX 8850 switch can support up to 192 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, VBR, ABR, and UBR with per-VC queuing on ingress and multiple
class-of-service queues on egress.
• Statistics collection.
• Virtual path connections (VPCs).
• Network synchronization derived from one of its lines.
• Bit error rate test (BERT) functionality with loopback 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 for through the optional MGX-SRM-3T3/B card.
• Automatic card-restore.
• SNMP and TFTP to support card and connection management.
• Resource partitions for individual network control applications.
