Keeping with the current trend of full integration IP and broadband, OPNET Technologies presents the high density, high capacity MSAN system shelf (MSA) of ULC-1000AN MSAN. The MSA system is a member of ULC-1000AN MSAN product series. It can be configured to deploy a wide range of voice and data applications, to subscribers over a copper wire-line network infrastructure. Combined the MSA and MSC shelves in one integrated MSAN system, ULC-1000AN MSAN fully supports all TDM-based, ATM-based and IP-based services in a single platform.

The MSA system shelf is equipped with 20G non-blocking backplane, and 1 Gbps per service slot, failover-enabled for Central Process Unit (CPUM2) and Media Gateway Unit (MGUM), dual power inputs and various high port density multi-purpose line cards. With comprehensive IP-centric firmware features, the MSA system is a high-density, high-capacity system that facilitates Telecom Operators to deliver high-quality residential or business user services, satisfying its current and future infrastructural requirements of reliability, flexibility and scalability. The MSA system shelf is an 11.1 U-height chassis-based MSAN system, it contains 15 vertical service slots, four half sized CPU/MGU slots, user panel and FAN unit on top. The Central Process Unit, CPUM2, control card with 6G grouping uplink is designed to plug into CPU-slots. Two Gigabit Ethernet optical ports are available on each CPUM2 card. The Media Gateway Unit, MGUM, VoIP protocol processing card is designed to plug into MGU-slots.

The 15-service slots are available for equipping various line cards. The variety of line cards are including: 48-port ADSL2+ line cards (with or without built-in splitter) that provide subscribers with asymmetric transmission bandwidth up to 24 Mbps/2.4 Mbps; 24-port SHDSL line cards with symmetric transmission bandwidth of 4.096 Mbps (2-wire); 24-port VDSL2 line cards (with or without built-in splitter) that offer up high-speed connectivity per port over copper wires 48-ports POTS line card provides telephone service. The designed of MSA shelf is also taking account of the further technology evolution such as GE-PON and EFM-G.SHDSL. The MSA system provides various management methods: local console port, Web-based, Telnet and SNMP v1/v2-based EMS. The management functions include Alarm and Status Surveillance, Configuration management, Performance management, Fault management and Security management. The EMS allows multiple administrative accounts with 3-level access privileges.

Accounts with the first-level privilege have full access to all management objects. Second-level accounts have similar access rights except creating new administrative accounts, while the third-level accounts are granted read-only access rights to the management objects. The EMS also provides view-based management that partial objects can be defined and accessed for customization and security reasons. In addition, Cluster Management enables multiple MSAN administration with single/master IP address, northbound interface is optional equipped in EMS to interoperate with external OSS systems.
