Element Management

The AAC family supports local and remote access via in-band or out-of-band connections. All products include an embedded SNMP agent and standard and enterprise MIBs, compatible with SNMP-based management systems. You can also Telnet to the devices via the Ethernet port on the Integrated System Controller or an in-band ATM/Frame Relay connection. The native user interface is menu driven, making port and connection configuration quick and easy.

Traffic Management

You can maximize the utilization of expensive wide-area bandwidth with AAC traffic management features. The Enhanced Shaping Cell Protocol Module performs traffic shaping on a per-VC and per-VP basis, ensuring that traffic meets the rates contracted with your carrier. This prevents cell discard and retransmissions, improving the overall use of available bandwidth. Connections exit the module through a weighted-fair queuing (WFQ) mechanism that ensures each connection gets scheduled bandwidth, even in the presence of congestion. The system uses early-packet discard (EPD) to reduce congestion quickly and to maximize network utilization.

Other AAC modules increase bandwidth utilization by reallocating idle CBR bandwidth. The Octal CES module monitors the CAS voice on/off hook status and V.35/CBR handshake signals. When a

connection goes idle, the system can terminate the cell stream so that the bandwidth can be used by other VBR connections.

Performance Monitoring

AAC systems collect extensive statistics, including port and cell utilization, cell and packet discard, and physical line errors. You can view the information in table or graphical form. With this information you can monitor network performance, anticipate growth in bandwidth requirements and trouble- shoot problems in both the local and wide area networks. The products also support a full range of loopbacks including line, local, and payload. In OC-3/STM-1 networks, you can insert BIP and AIS errors to test sections of that link.

Standards Compliance

AAC products comply with the relevant standards of the ATM Forum, ITU-T, Bellcore/Telcordia, the Frame Relay Forum, and the SMDS Interest Group. This alleviates compatibility issues in multi-vendor networks and reduces the risks associated with pro- prietary solutions.

ATM Forum specification compliance includes ATM UNI 3.0 and 3.1; Traffic Management 4.0 with support for CBR, rt-VBR, nrt-VBR and UBR QoS categories; Circuit Emulation Services 2.0 with support for structured or unstructured CES; and Inverse Multiplexing for ATM (IMA) 1.1/1.0
