ADTRAN targets network convergence with Advanced Services Architecture

Taking aim at the inefficiency of managing different networks for different services, ADTRAN, Inc. has unveiled its Advanced Services Architecture concept. The architecture is optimized to deliver a mix of residential, enterprise, and mobile backhaul services over a common network, including the provision of service management and network automation. The result is an approach that obviates the need for the deployment of overlay networks to offer new service types, ADTRAN says.

The new architecture leverages ADTRAN’s traditional strength in multi-service access platforms (MSAPs). Major elements of the Advanced Services Architecture include:

• Network automation and services management via web-based services APIs to simplify end-to-end provisioning of FTTP, FTTN, and Carrier Ethernet services, while abstracting service layer functions to support the transition to SDN and NFV environments. Integrated service assurance tools enable operators to manage and monitor subscriber SLAs, ADTRAN says.
• MSAPs optimized for both ANSI and ETSI markets, including a compact, edge-optimized MSAN for remote cabinet and building basement aggregation for a full range of services access modules. The line also includes a high-capacity, centralized aggregation platform for larger cabinet and central office applications.
• High-density, non-blocking fiber aggregation for 1G and GPON service delivery with non-blocking backplane connectivity. High-capacity switch fabrics for support of non-blocking access to service modules and up to 80G of network uplink capacity are part of the line.
• A range of network termination equipment and customer premises equipment that include broadband-optimized gateways, ONTs, and ONUs to support zero-touch activation of enterprise services, small cell backhaul, and multi-dwelling unit (MDU) locations.
• Integrated packet optical aggregation and transport. Network and subscriber interfaces include DWDM, 10G, and OTN, which will support both data center and mobile backhaul connectivity.
• Support of VDSL2 and system-level vectoring to support 100 Mbps and greater residential/small cell and 800 Mbps enterprise service delivery over copper. The architecture also supports EoCu and EoTDM aggregation and gateway systems.
• The ability to accommodate TDM transition in three applications: via an integrated voice gateway to migrate from TDM to VoIP architectures for voice transformation in FTTx and switch collapse applications; via an integrated TDM gateway for migration of TDM services onto an all-Ethernet network; and via ADTRAN’s IPBG portfolio to support IP telephony.
  

“All service segments in the wireline network are converging towards a future-state that consists of high-capacity, SLA-based Ethernet and wavelength services that can be delivered at any point in the network with rapid service activation.” said Robert Conger, director, product management, ADTRAN Carrier Networks Division. “The ADTRAN Advanced Services Architecture is enabling our customers to address this industry transition in a way that is truly delivering on the promise of consolidating and integrating business, residential and mobile backhaul service delivery onto a single network.”

ADTRAN will roll out the Advanced Service Architecture via upgrades to current platforms, including the flagship Total Access 5000, as well as the introduction of new systems. In fact, concurrently with the announcement of the new architecture, the company also unveiled the Total Access 5004, a small form factor MSAP designed to provide broadband access in low-density and “hard to reach” service areas. The 2 RU platform is designed for space-constrained cabinet retrofits and small remote terminal applications. It is configured to support a wide number of services and applications, including:

• Fiber-to-the-premises (FTTP) for VoIP, IPTV, and business Ethernet services via provision of 32 GPON OLT ports or 96 point-to-point Ethernet ports
• Fiber-to-the-node (FTTN) with support of board-, system- and multi-system level VDSL2 vectoring that can transition to FTTP
  10G packet optical edge applications for aggregation and transport of high-bandwidth services via thirty-two 10 Gigabit Ethernet or OTN ports
• MEF-certified Carrier Ethernet services delivery over fiber or copper
• Mobile backhaul with simultaneous support of large installation 10GbE urban 4G-Advanced cell towers or remote radio heads (RRHs) over CPRI, OTN, or WDM, as well as small or metrocell backhaul over GPON, bonded SHDSL, or vectored VDSL2.
