If you are looking for a backbone network that provides you with a way to accommodate additional capacity as your needs increase, AT&T Synchronous Optical Network (SONET) services may be just the solution. SONET offers you high-speed service for consolidating your voice, data, Ethernet and video traffic on one optical fiber access service and connect your existing applications to it. AT&T is an expert in providing SONET connectivity in metropolitan areas for organizations such as yours, with our data-intensive applications and currently more than 106,000 SONET nodes and 7.7 million fiber strand miles in the AT&T network. We have solutions to meet the growing demands of your backbone network capacity.
SONET has the power and capacity to fully integrate all your WAN traffic, making it an economical, enterprise-wide solution. We will help you determine the best configuration – with economics, simplicity, and future growth in mind – between SONET ring service or point-to-point. SONET lets you consolidate Ethernet, data, video, and voice traffic among your locations and AT&T central offices on a single, reliable platform. SONET can sustain as much as 9.95 gigabits per second (Gbps) of traffic, giving you the bandwidth to support your communications. SONET services are available in capacities that include OC-3, OC-12, OC-48 and OC-192. Think of a SONET ring as a customized network solution to support your data, video, and voice transport needs. The components of a SONET solution include the type of configuration and the level of bandwidth.
- Range of speeds and connectivity options
- Flexibility to carry your voice, data, imaging and video traffic
- Easily scale to meet your additional bandwidth requirements
- Minimal capital investment
- Lower cost per Mbps than digital
- With OPT-E-MAN
- Ability to customize your network to meet immediate operational needs
- Flexible and integrated add/drop multiplexing
- Customized network design to provide you with
- Redundancy built into the SONET equipment

Features & Options
SONET uses the following components:
Links/Local Channels – include interoffice facilities, the local loop, and alternate wire center. A link consists of two pairs of fiber optic transmission media connecting the nodes on the ring.
Access Ports/Channel Interfaces – at the central office and your facilities are the application handoffs to enter and exit the ring. Access ports come in a variety of bandwidths: DS1, DS3, OC-3, OC-3/c, OC-12, OC-12/c, OC-48, OC- 48/c, and various Ethernet interfaces.
Nodes – operate as the SONET add-drop multiplexer in a ring structure. Nodes are dedicated components located at the AT&T central office and your premises.
Optical Line Termination Equipment – forms a network interface (NI) for SONET OCN Point-to-Point service. This is the point where your network “plugs in” to the AT&T SONET service. Consequently, you get all the benefits of fiber optic technology while maintaining the same premises equipment, such as routers, PBXs, computers, and computers.
We offer you the following options with SONET:
SONET Ring Service – In ring configurations, we design, install, provision, and provide 24×7 network monitoring through one of our Network Operations Centers for every node in your network. We can also supply you with additional equipment and maintenance for your business network needs.
Ethernet over SONET – Ethernet over SONET (EoS) is Ethernet data mapped to a SONET payload and carried over a synchronous optical network. EoS contains minimal SONET payload, providing you the necessary bandwidth for LAN-to-LAN interconnection. We implement EoS through ingress and egress ports on Dedicated SONET Ring Service and SONET Ring Access Service.
The Ethernet interfaces include 100 BaseT (offering 50 Mbps and 100 Mbps) and 1000 BaseSX and LX (offering 50 Mbps, 150 Mbps, 600 Mbps, and 1000 Mbps). We will work with you to appropriately size and engineer your network to help ensure optimal performance. We will install, maintain, and monitor SONET carrying Ethernet traffic for you.
Ethernet over SONET Schematic With an Ethernet over SONET option, you can magnify the power of SONET by including Ethernet protocol data as well as other protocols (e.g., ATM, frame relay, DSx transmissions, etc.) on your network.
Point-to-Point SONET Service – With Point-to-Point SONET service, you receive full network design, installation, provisioning, and 24×7 network monitoring from fiber network handoff to fiber network handoff. Additionally, you can choose a fully-managed customer premises equipment (CPE) and maintenance plan to cover handoff points.
OCN Point-to-Point Service 1+1 Protection Point-to-Point 1+1 protection provides you with card-level protection at the AT&T wire centers.
