VERSA Technology develops the high density, high capacity MSAN system shelves of VX-2000HDx MSAN to meet the market trend and customer requirement. MSA, MSB and MSG are members of VX-2000HDx MSAN product series. Those can be configured to deploy a wide range of voice, data and vide applications, to subscribers over copper or fiber wire-line network infrastructure. Combined with the legacy existing MSC shelves in one integrated MSAN system, VX-2000HDx MSAN fully supports all TDM-based, ATM-based and IP-based services in a single platform.

Those high density MSA/B/G shelves are equipped with non-blocking data connection backplane, providing 2 Giga-bits data rate for each service slot, failover-enabled for Central Process Unit (CPUM2, CPUC or CPUCG) and VoIP Media Gateway Unit (MGUM), dual power inputs and various high port density multi-purpose line cards. With comprehensive IP-centric firmware features, MSA/B/G system are 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/B/G are high density chassis-based MSAN systems. MSA shelf contains 15 service slots, and MSB shelf contains 8 service slots. Both shelves also have four half sized common unit slots to support 1+1 redundancy, user panel and FAN unit. MSG shelf contains 4 service slots, two half sized common unit slots, user panel and FAN unit. The Central Process Unit, which equipped with number of Gigabit Ethernet (GE) ports for grouping uplinks, is designed to plug into CPU-slots (C1 and/or C2). The Media Gateway Unit, MGUM, is VoIP protocol processing card, and be designed to plug into MGU-slots (M1 and/or M2). Service slots are available for equipping various service line cards. The variety of service 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 VDSL2 line cards (with or without built-in splitter) that offer high-speed connectivity (100/50 or 100/100 Mbps) over copper wires.

72/48 ports POTS FXS line card provides telephone service.

4-ports GPON OLT line card provides FTTx high speed broadband service.

The designed of those system shelves are also taking account of the technology evolution such as IEEE Ethernet PON and EFM-G.SHDSL.

VX-2000HDx MSAN system supports various management methods: local console port, Web-based, Telnet and SNMP v1/v2-based EMS. The management functions include, Configuration management (CM), Performance management (PM), Alarm and Status Surveillance Fault management (FM) and Security management (sM). 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.

The VX-2000HDx MSAN system has a very versatile and integrated design well-fit for most application scenarios in access network and comply to latest relevant ITU-T and IEEE standards, which include following services:

*Various of Service Type

- POTS (packtized VoIP)

- Payphone (packtized VoIP)

- ISDN (PRI and BRI) (ISDN over IP)

- ADSL, ADSLS2, ADSL2+

- SHDSL (2-wire / 4-wire)

*Applications

- H.248/MGCP/SIP Access Gateway (AG)/Media Gateway (MG)

- IP based Digital Subscriber Line Access Multiplexer (IP-DSLAM)

- Multi-Service Access Network System (MSAN)

- Passive Optical Network (PON)

VX-2000HDx MSAN High Density Equipment Shelves

The MSA shelf contains a backplane with 15 line card slots, the MSB shelf contains a backplane with 8 line card slots, and the MSG shelf contains a backplane with 4 line card slots. All MSA/B/G backplanes have a TDM bus for VoIP applications and a dual IP stars connection (for 1+1 redundancy) from the switch fabric card (CPUM2/CPUC/CPUCG) to each line card slot. The bandwidth from the CPU switch fabric slot to each line card slot is two gigabit per second bandwidth, which is sufficient for all foreseeable applications.

All MSA/B/G systems are best suited for high density broadband applications and suited for VoIP applications and multi-service broadband applications as well.

 MSA/B/G Backplane Connections

The MSA/B/G and the legacy MSC (CBA-C) shelves can be linked together to optimize performance and cost for different applications. A single network management system, VERSAView, is used to manage all shelves in the same MSAN system from the same connection point of any shelf type.
