Carrier Ethernet is a fundamental element of the Cisco® Evolved Programmable Network (EPN). This is a proven end-to-end network solution for video, mobile, and cloud, which can help customers increase revenue opportunities while reducing costs. It helps service providers develop a truly integrated, multidirectional network infrastructure in which all elements, from the core to the edge, access, aggregation, and data center, are intelligently linked and orchestrated to work together.
Over the years, fiber-based access has proven to be a cost-effective way to reach customer premises to deliver managed business and residential services. The Cisco ME 4600 Series Optical Line Terminal (OLT) portfolio offers an exceptionally broad and scalable solution that gives network service providers a flexible and cost-effective approach for optical fiber access solutions over active or passive optical network architectures.
The Cisco ME 4600 Series Multiservice Optical Access Platform includes reliable modular OLT devices specifically designed for optical fiber network infrastructures in either point-to-point (P2P) or point-to-multipoint (P2MP) topologies. Ethernet or passive optical network (PON) technologies like Gigabit PON (GPON) are supported. Next-generation PON technologies like XG-PON1 (10GPON) and NG-PON2 (TWDM PON) will also be supported by the same Cisco ME 4600 Series OLT. The Cisco ME 4600 Series OLT can support any FTTx scenario, covering fiber-to-the-home (FTTH), fiber-to-the-building (FTTB), fiber-to-the-curb (FTTC), fiber-to-the-cell (FTTc), and fiber-to-the-business (FTTb).
Figure 1. Cisco ME 4600 Series OLT
Cisco offers a comprehensive portfolio for passive optical fiber access networks. The Cisco ME 4600 Series OLT solution is based on ITU-T Recommendation G.984.x (GPON) and G.988.x (OMCI). The same network equipment solution allows service providers to evolve toward next-generation PON architectures as defined by the ITU-T Recommendations G.987.x (XG-PON1) and G.989.x (NG-PON2) for both central office and customer premises.
For the central office, the Cisco ME 4600 Series Multiservice Optical Access Platform portfolio is based on a flexible and scalable architecture. Cisco offers the best-of-class solutions in the market designed to evolve easily, from rural and low-density multidwelling unit (MDU) scenarios, using only 8 Gigabit Ethernet and 8 GPON port equipment (Cisco ME 4601 OLT, shown in Figure 1), up to urban and extremely high density, using 768 Gigabit Ethernet and 256 GPON port equipment (Cisco ME 4620 OLT, shown in Figure1). Cisco ME 4600 Series OLT equipment also implements the features required for residential, business, and enterprise services to be provisioned on an end-to-end basis, with appropriate service-level agreements (SLAs), thus allowing required bit rates to be reserved for each dedicated client's needs.
The Cisco ME 4600 Series OLT is a reliable high-availability system that uses common-element 1+1 protection for power, control, switching, and processing, with load balancing link aggregation groups (LAG) and Link Aggregation Control Protocol (LACP) at the uplink interfaces. Ethernet ring protection switching (ERPS) mechanisms based on ITU-T G.8032 are available for access-network upper-layer interconnection. For the client side, Type B protection for GPON ports is available according to ITU-T Recommendation G.984.x. From a security perspective, the Cisco ME 4600 Series OLT supports features that help prevent denial of service (DoS) attacks and fake customer Trojan mechanisms, including Access Control Lists (ACLs), MAC duplication prevention, MAC and IP spoofing prevention, broadcast rate control, and user isolation.

Major Applications
The massive growth in demand for high-bitrate connectivity to support the consumption of multimedia data is driving the need for new technologies in both business and consumer markets. Specifically, the growth in video traffic at home and at work, along with the growing trend towards cloud-based computing delivered across multiple, varied devices, is pushing both fixed and mobile operators in both developed and emerging markets to roll-out FTTP services.
Residential Services
The Cisco ME 4600 Series OLT supports residential broadband aggregation for delivering multiplay services over optical fiber access networks. Designed to support thousands of subscribers from a single OLT, the Cisco ME 4600 Series OLT offers multiple deployment and provisioning models, including 1:1 and N:1 VLAN configurations with quality of service (QoS), resulting in a greatly enhanced broadband user experience. The feature-rich Cisco ME 4600 Series OLT supports a variety of broadband video applications, including RF overlay, IPTV, and video on demand (VoD), with support for IP multicast (IGMPv2/v3 and MLDv2) and Dynamic Host Configuration Protocol (DHCP) Relay Agent (DHCP Option 82 for IPv4 and DHCP Options 18/37 for IPv6). These features enhance and extend the Cisco IP Next-Generation Network (NGN) architecture to the residential environment.
Business Services
The Cisco ME 4600 Series OLT is built to meet service provider requirements for Carrier Ethernet aggregation and transparent LAN services. The Cisco ME 4600 Series OLT offers service flexibility and delivers Layer 2 transport for advanced Layer 2 and Layer 3 VPN and business services, including circuit emulation services (CES) to transport time-division multiplexing (TDM) traffic over packet networks with appropriate clocking, synchronization, and timing features. VLAN translation and promotion features with the required QoS complement the comprehensive functions needed to interconnect business branches over a P2P or P2MP network topology.
Mobile Backhaul Services
With the growing demand on mobile backhaul networks to support third-generation (3G) and fourth-generation (4G) services, PON and Gigabit Ethernet have become the most common options for backhaul. Deployed as a pre-aggregation platform for mobile backhaul, the Cisco ME 4600 Series OLT can aggregate cell sites and serve as a transport solution for Radio Access Network (RAN) backhaul traffic. The Cisco ME 4600 Series OLT provides the timing services required in today's converged access networks by offering integrated support for the Building Integrated Timing Supply (BITS), 10 MHz, 1 pulse per second (1PPS), and time of day (TOD) interfaces. The Cisco ME Series 4600 OLT also supports synchronous Ethernet (SyncE) and IEEE-1588 functionalities, and it can act as the source for network clocking for TDM, SDH and SONET, SyncE, and GPS interfaces. In addition to the timing services, the Cisco ME 4600 Series OLT offers a compact option that can also be deployed in small and harsh environments, due to its shallow depth and qualification for extended temperature ranges.

Cisco ME 4600 Series OLT Features
To meet the growing demand for higher bitrate, service providers require an FTTP solution that is cost effective, easy to deploy and manage, scales well from an aggregation standpoint, and provides the means to offer both end-user and wholesale service models. The explosion in data traffic on both fixed and mobile networks is creating new challenges for all service providers, and Cisco can offer competitive advantages through the adoption of the latest in FTTP solutions.
The Cisco ME 4600 Series OLT helps service providers deploy next-generation optical access networks with improved margins, by reducing costs, increasing revenue streams, and supporting new, higher-value business and residential multimedia services. These improvements can be achieved with the following product features:
• Higher maximum switching capacity (8.6 Tbps) and switching capacity per slot (up to 120 Gbps): This saves service providers' capital expenditures (CapEx), because the chassis will not need to be replaced when they deploy next-generation PON technologies (XG-PON1 and NG-PON2).
• Higher port density per rack unit (up to 256 GPON ports or 768 Gigabit Ethernet ports per 13 RU): This supports more ONTs per chassis, with more competitive and effective CapEx per port.
• Service-focused provisioning: This provides an easy-to-use management interface and helps reduce operating expenses (OpEx). The Cisco ME 4600 Series portfolio makes it very simple and easy to provision High-speed Internet, voice, video, and TV services through all types of management interfaces (CLI, web user interface, and EMS Agora-NG). The fact that the system abstracts lower level access technology capabilities from the operator is an important advantage for reducing management costs and implementation time.
• Cisco end-to-end solution: This helps reduce OpEx, and service providers can benefit from interoperability with other Cisco aggregation, edge, and core products.
• Cisco Prime™ Carrier Management integration: Service providers who already use or are planning to use Cisco Prime Carrier and its management components (Prime Central, Prime Network, and Prime Performance) for other Cisco aggregation, edge, or core products can also benefit from it for managing the Cisco ME 4600 Series products as part of the same unified management solution.
