RAD’s Network Management Solutions Enable Incumbent Vietnamese Carrier to Efficiently Control Service Provisioning throughout the Country
VTN, the largest carrier in Vietnam, owns and operates the nation's backbone network, which connects 64 provinces via three sub-networks: VTN-1, with its network operations center (NOC) in Hanoi; VTN-2, servicing the Ho Chi Minh City area in the south; and VTN- 3, controlled via Da Nang. In addition to providing inter-province connectivity to local carriers, VTN delivers business services to banks, corporations, and small to medium enterprises (SMEs), including virtual private networks (VPN), leased lines, voice, and video conferencing. “VTN has deployed over 10,000 units of RAD’s multiservice access platforms (MAP) and Last Mile products to deliver these services,” described Namson Tran, Managing Director of NTCOM VN, RAD’s distribution partner in Vietnam, which supplied the devices and oversaw their implementation. The installed base includes a wide range of CPE (customer premises equipment), aggregation nodes and network edge devices.
“The large variety of products and services, as well as the vast geographical area they cover, can't be operated and administered without a carrier-grade network management system that provides effective control up to the customer premises,” continued Tran, “which is why VTN has selected RAD's RADview-EMS (element management system) to achieve these goals.”
Advanced FCAPS Functionalities
RADview-EMS is a Java-based, carrier-class element management system for Windows and UNIX environments. It manages RAD’s TDM and next-generation devices using distributed client/server architecture and features advanced FCAPS (Fault, Configuration, Accounting, Performance, and Security) capabilities, accessible via a Web- or SNMPbased agent. Providing visual network representation with an intuitive GUI, RADview-EMS allows easy configuration, troubleshooting, diagnostics, and statistics collection by remote VTN operators.
Each of VTN’s three sub-network centers in Hanoi, Ho Chi Minh City and Da Nang is equipped with a RADview-EMS platform to autonomously manage VTN-1, 2 and 3, respectively. This includes remote provisioning and fault monitoring throughout the network. The three RADview NMS stations are interconnected to allow complete visibility across VTN’s footprint; management authorization for each station, however, is restricted to its respective sub-network. Within the sub-network domains, RADview platforms allow VTN NOC personnel to define access levels for individual network elements according to menus, IP address range and other criteria.

Ensuring Service Continuity and Disaster Recovery
As the sole supplier of the telecom network services that connect the nation's provinces, VTN requires a high degree of protection to ensure service resiliency in the event of network failures. Luckily, RADview-EMS features enhanced support for business continuity and disaster recovery (DR). Each of the three RADview NMS stations serves as a backup system for the other two, with metro-level as well as local backup capabilities. RADview- EMS's Backup and Restore functions enable an efficient changeover from the main NMS to a redundant station without affecting the service. “Not only does RADview ensure seamless operations,” said Ofer Rachman, General Manager, RAD Far East Ltd., “it also saves VTN the cost of additional DR software tools and expensive storage equipment.”
“VTN is consistently pleased with the quality of RAD products and the level of support they offer for both current and future needs,” concluded Tran. "The RADview NMS, for example, is already equipped with a range of northbound API (application programming interface) channels, so that when VTN decides to integrate it with its OSS (operations support systems), there's no need to upgrade the entire system.”

Incorporating TC-PAM technology for extending the transmission range, the SHDSL modems enable carriers to cost-effectively reach more users with copper lines at higher data rates over longer distances in the First Mile. The devices address the data transmission and Ethernet extension needs of enterprise users. Typical users include municipalities, utilities, corporate connectivity, and cellular backhaul providers.
The point-to-multipoint devices can broadcast any traffic combination from a single input to numerous destinations and provide non-blocking cross connect for up to 120 lines. The DXC family modular digital cross-connect units support E1/T1 conversion, inverse multiplexing, signaling monitoring, grooming of fractional traffic, and transmission of T1 circuits over E1 lines.
The Megaplex-2100 and Megaplex-2104 are especially suitable for use as economical, compact remote multiservice nodes for utilities and transportation. In addition, the Megaplex-2100 and Megaplex-2104 are ideal for small to mid-size business entities, providing mixed data and voice services for both business and residential customers. They can be deployed at the carrier’s point-of-presence in the exchange, as well as at a remote distribution node, such as in an office building’s basement.
The Optimux-1551 combines the high capacity associated with SDH/SONET add/drop multiplexers (ADMs) with the simplicity and low cost of a terminal multiplexer to significantly reduce OpEx and CapEx. Extending point-to-point services over coax or fiber to remote locations, the Optimux allows service providers to increase their customer reach, while avoiding the cost and complexity associated with deploying high-end ADMs. Furthermore, the Optimux-1551 eliminates the need for deploying PDH multiplexers at customer sites by consolidating traffic at the edge of the SDH/SONET network. This enables service providers to save the cost of fiber deployment and multiple ports on the ADM.
The RADview features a network element manager, end-to-end service manager for Carrier Ethernet services, performance monitoring portal for ongoing monitoring of Ethernet and IP services, D-NFV orchestrator for virtual machines and application services at the customer edge, and a network planner for resource optimization and capacity planning.
Featuring client/server architecture with multi-user support, RADview provides intuitive graphic representation of network clouds, links, nodes, end-to-end services, and network status indication. Fully ITU-T FCAPS compliant, it offers security management supporting user access profiles and allowing network partitioning.
