SONETS Technical Summary

SONETS is a Networx service that enables Agencies to build optical transport networks that are high bandwidth, with a high level of reliability and traffic isolation. These transport networks are built using facilities from the contractor's optical backbones. SONETS provides proactive performance monitoring and enables self-healing functions with robust network management.

SONET is the U.S. standard for fiber optic synchronous transmission rates from 51.84 Mbps (OC-1) to beyond 13.27 Gbps (OC-256). The International Telecommunications Union version of the standard is the Synchronous Digital Hierarchy (SDH), which begins at 155 Mbps. SONETS is capable of interoperating with SDH in CONUS by providing gateway functions to transport SDH traffic over a SONET infrastructure.

The diagram below illustrates a CONUS wide optical transport network built over a contractor's optical backbone that interconnects Agency's headquarters with branch offices. The Agency's optical network depicted is able to deliver bandwidth via electrical User to Network Interfaces (UNIs) i.e. DS1, DS3, E1, E3 and optical carrier (OC) interfaces i.e. OC-3 up to OC-192.

The contractor's optical backbone in the example below is built by multiple SONET rings designed with two different protection methods (e.g., UPSR, BLSR). The core rings use Bidirectional Switched Ring (BLSR) protection and the metro/access rings uses Unidirectional Path Switched Ring (UPSR) protection. The protection methods define the amount of bandwidth allocated for protection and the number of fibers used for interconnection.

Example SONETS Implementation

SONETS may be ordered in Metro areas or long haul CONUS wide, with OCONUS and Non-Domestic locations optional to offer. As specified in Section C.2.5.2.1.3 of the Networx contracts, the Agency can order SONETS that will connect to and interoperate with:

• Government specified terminations (e.g., Service Delivery point (SDP)-to-SDP, Point of Presence (POP)-to-POP).
• All other networks including other Networx contractors networks where industry standards are used.

General

Basic SONETS is a point-to-point bi-directional, single link service. Private networks with more complex topologies such as rings and mesh can also be provided with Next Generation SONETS capabilities.

SONETS transport technologies have evolved from a strict Time Division Multiplexing (TDM) channel allocation to more flexible bandwidth allocation methods provided by Next Generation SONET technologies. These include Link Adjustment Capacity Scheme (LCAS), Generic Framing Procedure (GFP) and Virtual Concatenation (VCAT). Basic SONET has always enabled Agencies to interconnect dissimilar networks such as Asynchronous Transfer Mode (ATM), Frame Relay (FR), and IP. However, with the additional protocols supported by Next Gen SONET (LCAS, GFP and VCAT), bandwidth efficiency has been considerably improved.

SONETS Technical Capabilities

Agencies subscribing to SONETS may opt for a single connection point-to-point which will be a dedicated connection between two sites with a dedicated, built-in protection channel that will not be used by any other customer's traffic. The Networx contractors support other network topologies such as rings and mesh. More detailed descriptions of SONETS capabilities are provided in Section C.2.5.2.1.4 of the Networx contracts.

SONETS Features

SONETS features that may be orderable are detailed in Section C.2.5.2.2.1 of the Networx contracts and are listed below:

• Bandwidth On Demand (BoD - Optional to offer).
• Channelization (SONET interfaces to Agency CPE that seamlessly interface with the Contractor's SONET network for data transport).
• Dedicated Metro Ring.
• DS1 Rate Synchronization Services (Optional to offer).
• Equipment Protection1:1 and 1+1 - CPE (Protection to user network interfaces at the SDP, where the protection channel is bridged to a failed working channel).
• Network Protection.
• Framing for Electrical Interfaces.
• Geographic Diversity protection.
• Local and Remote Node Multiplexing.

Each Networx contractor may provide variations or alternatives to the offering and pricing for SONETS. The specific details can be found within each Contractors Networx contract files and pricing notes for SONETS.

For more information on the general SONETS specifications and requirements, please refer to Section C.2.5.2 of the Networx contract for technical specifications and Section B.2.5.2 for pricing.

SONETS Price Basics

SONETS is highly reliable transport that provides proactive performance monitoring thus preventing single and multiple failures, and further enables self-healing functions and robust network management. SONETS is a service that was not offered on the original FTS2001 contracts. SONETS is available as:

• Fixed Bandwidth (FB): Transport based on a fixed amount of bandwidth
• Bandwidth-on-Demand (BoD): Transport based on measured bandwidth usage (BoD is optional for Networx contractors. It is currently not offered but may be offered in the future.)

The MRC for transport consists of a fixed component plus a distance-dependent (per mile) component. The mileage charge for SONETS transport is based on the total mileage between the contractor's designated connecting POPs for any two customer locations. CONUS-to-CONUS distance is calculated using the distance formula:

• Distance (miles) = ROUNDUP(SQRT(((V1-V2)^2+(H1-H2)^2)/10),0)
  
• Where (V1, H1) and (V2, H2) are the V and H coordinates of the locations, respectively

Distance involving OCONUS or non-domestic locations is calculated using airline miles. Note: The Networx Pricer automatically calculates the distance when given the originating and terminating locations.

Price components required for full end-to-end service for Domestic and Non-Domestic FB SONETS:

• SONETS Transport monthly recurring charge with a fixed component and charge per mile.
• DAA Originating and Terminating Wireline Access (MRC) and (NRC)
• Features ordered as needed by the Agency
  • Channelization
  • Dedicated Metro Ring is priced on an Individual Case Basis (ICB). CLINs with ICB prices are not available in the unit pricer
  • Equipment Protection 1:1 - CPE
  • Equipment Protection 1+1 - CPE
  • Equipment protection - Network Side
  • Framing for Electrical Interfaces
  • Geographic Diverse protection
  • Local and Remote Node Multiplexing
• Service Enabling Devices (SEDs) may be required to implement SONETS. [Please note that SEDs under Networx replace the FTS2001 User-to-Network Interfaces and Access Adaptation Functions (UNIs/AAFs). SEDs may differ between Networx providers. The pricing structure for SEDs provides for either a one-time payment or monthly term payments for purchase, plus a NRC for installation and a MRC for maintenance.]
