2.8 Network Transmission and Synchronization Plans (L.38.1.1(h))L.38.1.1(h) Network transmission and synchronization plans for the various services.

Network synchronization, the communication timing within and between networks, plays

a critical role as high-speed communication networks span the globe. Sprint is particularly

well suited to handle the Government’s demand for worldwide data transmission because of

our 100 percent digital, fiber-optic network in the U.S.—the ideal transmission medium for

high-speed data transmission.

Digital network synchronization, as implemented on the Sprint network, assures that the

network will transport data end-to-end and interconnect with other networks with no, or

minimal, degradation. The benefits of Sprint synchronization include transmission clarity,



virtually error-free operation, and survivability using Digital Cross-connect System (DCS)

devices.

Sprint uses either a LORAN (long range navigation) or a GPS (Global Positioning

Satellite) Primary Reference Source at all of our nodes and switch sites to provide the

Government with state of the art plesiochronous synchronization. Plesiochronous

synchronization is a false synchronization that allows network independent synchronization

at each

location.XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXAs the first U.S. carrier to

provide 100 percent fiber-optic transport with plesiochronous synchronization, Sprint

provides Stratum 1 timing sources at different network nodes rather than one centralized

source. The plesiochronous technique does not experience the timing degradation of long

timing distribution links. This synchronization method is also uniquely suitable to a total

fiber-optic network because of the automatic reconfiguration capability provided by diverse

fiber links from a node to different Stratum 1 clocks, which are provided via Loran-C

systems. The Loran-C system, maintained by the U.S. Coast Guard, is a low-frequency

terrestrial radio navigation system. It operates from 90 to 100 kHz, with a carrier frequency

of 100 kHz. Because these low frequency radio waves follow the earth’s curvature, they are

both stable and unaffected by the ionosphere. Loran-C transmissions are referenced to

Cesium Beam frequency standards (Stratum 1) and are Universal Time Coordinated (UTC).

The benefits of the Loran-C synchronization method are assured through multiple redundant

Stratum 1 primary reference sources.

The GPS system uses atomic clocks mounted inside satellites for distributing UCT

(Universal Coordinated Time) timing. These satellites then transmit timing beacons that

cover broad areas of the earth. Originally developed for military use, GPS has recently been

made available for commercial applications.






XX

Sprint will also provide timing to Government Furnished Equipment (GFE) for digital

User to Network Interfaces (UNIs) when the access is provided by Sprint. The Government

should derive timing from these digital UNIs by setting the GFE to derive timing from the

network. The GFE will synchronize the transmit path to the receive path, thus insuring

integrity of synchronization across digital networks.

For analog UNIs, Sprint can not provide timing to GFE. Analog UNIs do not require

digital timing. Examples of analog UNI applications are telephones served by a 4kHz UNI

and analog modems of speeds to 33.6 kbps.

For any type of Switched Circuit access originating or terminating through the PSTN,

including PRI and BRI, the Government should derive timing on digital interfaces from their

access provider. This is the best commercial practice, and is fully supported by

Interexchange Carriers, Local Exchange Carriers, foreign Postal Telephone & Telegraph

companies, and most Competitive Local Exchange Carriers.

If the Government orders Class 1 dedicated access from a provider other than Sprint, the

Government must derive timing from that access provider. LECs and CLECs do not

synchronize their networks from Sprint. Generally, they provide their own synchronization

within their network, similar to Sprint’s synchronization plan. The Government should assess

the synchronization plan for these access providers to ensure they are properly synchronized

and capable of supplying digital timing. In addition, the Government will be responsible for

resolving timing errors at Sprint’s POPs where Class 1 access terminates. The Government

should understand Sprint is not responsible for timing problems on end-to-end service where

the access facilities are not ordered through Sprint.

Sprint, through its account teams, will assist the Government in devising a

synchronization plan for Agency networks. In complex networks, a logical plan to ensure

digital integrity takes planning and dialog between Sprint and the Government.



2.9 Approach for Incorporating Services (L.38.1.1(i))L.38.1.1(i) Approach for incorporating into the Offeror’s Network, at some future time, the emerging services listed in Section C.2.8 that

the offeror believes are likely to become commercially available in the time frame covered by this acquisition including discussion of

potential problems and proposed solutions.

Increased demand for communications services is converging from three sources: radio/

TV, data, and telephony. To meet the associated demand on network resources of these

emerging services, Sprint’s forward-thinking engineers are working with their customers to

meet their current and projected needs for transmission facilities. XXXXXXXXXXXX






XXXXXXXXXXXX













XXXXXXXXXX



These worlds are also highly dynamic. Services appear overnight and ramp up at

astronomical rates, new technologies create new services with unpredictable demands on

specific network resources. Since Sprint maintains its leadership position in planning for and

implementing emerging services, we are well positioned to customize these services for the

Government and provide the network resources to support them as well.
































































SONET enables the Sprint network to transport large amounts of bandwidth at

unprecedented speeds, while providing a flexible platform for expanding services.





































































XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX



Sprint will ensure all emerging services will interoperate seamlessly with FTS2001

services. Sprint will partner with the Government to test interoperability of emerging

services and features. This testing will incorporate all aspects of the service, from service

ordering to billing.



XXXXXXXXXXXXXXXXXXXXXXXXXXXX

Sprint has a long history of successfully migrating customers, including Government

customers, to new technologies, systems, and services. In 1987, Sprint laid the cornerstone of

its advanced broadband network strategy with the migration of traffic from an analog

microwave transmission system to a digital fiber based backbone. In 1988, Sprint

successfully implemented Signaling System 7 on its network. The company went on to

introduce SONET transmission, then SONET rings, the DINA platform for toll-free services,

and the migration to a commercial billing platform (IPS) for its commercial accounts. Sprint

also has introduced numerous back-office systems for customer support. These industry-

leading changes have been acknowledged by telecommunications experts, including

significant accolades such as the naming of Sprint Chief Technology Officer Marty Kaplan

as 1997 Technologist of the Year, and Sprint as Data Communications magazine’s 1998 data

leader.

2.10 Approach for Adapting to meet Government’s Service Requirements (L.38.1.1(j))L.38.1.1(j) Approach for adapting the offeror’s network and services to meet the Government’s evolving service requirements.

Sprint serves an extremely diverse client base. Customers range from large Federal

agencies with complex telecommunications requirements to plain old telephone service

(POTS) to individual citizens. The common denominators among these customers are that

each has unique requirements and demands the latest technology. As a result, customers’

requirements frequently drive the direction of our telecommunications resource development.

For example, the international ATM market continues to expand due to the demands for

high-speed bandwidth by the

The interaction with our customers inherently required in the development and execution

of complex transport services provides Sprint a valuable, unique opportunity to understand

and anticipate Government customers’ telecommunications needs. Members of the Program

Life Cycle Teams (LCT), led by the Program and Account managers, are the key participants

in this ongoing interaction.



To maintain our sharp customer focus, Sprint personnel pursue effective opportunities to

interact with, provide resources to, listen to and understand our customers. We participate in

industry trade shows, consortium special interest groups, associations, discussion panels and

seminars, encouraging customers to share needs and ideas, asking questions, presenting our

solutions, and building relationships. Additionally, Sprint frequently polls its customer base

to determine its overall customer satisfaction.

Maintaining attentive relationships with our customers enables Sprint to pro-actively and

efficiently adapt our network and services to meet the Government’s evolving service

requirements. Thorough understanding of the scope and range of the Government’s evolving

requirements allows the maximum leverage of economies of scale and optimization and

customization of resources.An example is Sprint’s XXXXXXAccount Team, which assessed

the rapidly increasing demand for satellite services, enlisted a subcontractor to provide cost-

effective service to multiple accounts, optimized the required capital investment, and

provided XXXXXXXXXXX customers with the flexible, reasonably priced, high quality

satellite service they required.

Additionally, Account Teams participate in and influence corporate-wide initiatives to

ensure that Sprint will provide specific solutions for the Government’s future requirements.

Sprint’s National Integrated Services organization is assessing future Government

requirements for bundled local and long distance service in an effort to ensure that Sprint is

maintaining our position of leadership in the expanding telecommunications industry and

supporting legislation allowing open competition.

New products and services are introduced to customer and potential Government

customers via pilot programs and field trials, the results of which are linked back to business

and market development groups, shaping Sprint’s strategic direction. Sprint emphasizes

Government customer participation in leading edge focus groups both internal and external

to the organization. Additionally, Sprint account and Life Cycle teams engage in program

reviews with the Government, encouraging their input and sharing of ideas. All of these



techniques are used by Sprint to listen and learn from the Government, and to develop

Government-specific applications.

The importance and value of key products and service features to our Government

customers is specifically documented in their Requests for Proposal (RFPs). Life Cycle

Teams (LCTs) monitor, compare and evaluate RFPs to identify specific demand trends.

Additionally, LCTs and account managers maintain attentive relationships with the

Government. For example, we are providing our Government customers with training on the

new Federal Telecommunications legislation, encouraging discussion on strategies to

optimize the Government customers’ benefit from the changing market.Sprint continually

assesses the Government’s evolving service requirements and develops plans to integrate

these needs with our strategic product and business goals. Sprint’s pro-active approach to

adapting our network is evidenced by our role in driving Sprint’s ATM, Internet, Frame

Relay, and Managed Network Services, all of which were direct results of evolving

Government requirements.

2.11 Domestic and International Service Coverage (L.38.1.1(k))L.38.1.1(k) Discussion of the offeror’s ability to meet the domestic and international service coverage requirements including limitations in

current coverage (especially non-domestic dedicated access) and the offeror’s plans for increasing this coverage after contract award and

during the term of the contract, including explicit lists of where and when services and features will be offered.

Domestic Coverage

Sprint’s coverage of the mandatory services far exceeds the requirements. Sprint delivers

a variety of services over its all-fiber backbone network, including:

• DCS-based services

• Circuit Switched-based services

• Cell/Packet-based services



Sprint has XXXPOPs in all 196 LATAs. These POPs are connected by Sprint’s 26,000

route miles of fiber-optic network. Sprint is adding additional mileage, additional

POPs, and route diversity. XXXXXXXXXXXXXXXXX All mandatory services

required under FTS2001 will be provided at allXXXSprint POPs.Digital Cross-Connect

Switch (DCS) Service Delivery

The DCS is used in the Sprint network for DTS service as well as for the integration of

all Sprint services.

XTrunking of the DCS is provided in a non-hierarchical manner. InterMachine Trunk

(IMT) groups interconnect each switch with all other equivalent switches within the network

and provide monitoring for all DS0 and DS1 services.

Circuit Switch Service Delivery

Digital switching architecture is based on a redundant design concept. Each common

component of the digital switching equipment, including the centralized processor units, is

fully duplicated. If a hardware or software failure occurs, the system automatically switches

from the active to hot standby components.

X

X

X

XX

X

X

XWhile circuit switched services have typically been perceived as supporting voice traffic,

switched data is also supported on the Sprint network. Dial-up voice grade data transmission

is currently provided as a permissive service or function on Sprint’s network. The network is

compatible with all modems that are designed for voiceband telephone networks.

X

X



XFunctionally, Sprint’s switched network is neither a voice nor a data network, but rather

a digital transport platform for transmission of switched data services.No distinction is made

at the network level between voice, voice band data, and data transport.

Customers with T1 or channelized T-3 access extend the basic digital capability of the

fiber-optic network to their service locations. X

Signaling System 7 (SS7)

Sprint was the first long-distance carrier to implement Signaling System 7 (SS7)

nationwide and the first to connect with a local exchange carrier (BellSouth in May, 1991).

SS7 provides immediate benefits in terms of network performance, operational efficiencies,

call processing, and the ability to develop advanced features for our

customersXXXXXXXXXX

Signaling System 7 was developed from the Common Channel Signaling (CCS)

international standards recommendations set by the ITU Telecommunication Standardization

Sector (formerly CCITT), the international telephony standards organization.

CCS is based on the concept of “out-of-band” signaling, in which signaling is a data

communications function and has its own channels on the network separate from the call

transmission facilities. SS7 was determined to be strategically important for the following

reasons:

• SS7 takes full advantage of fiber-optic transmission technology and meets the

requirements of recent ITU Telecommunication Standardization Sector and North

American standards activity.

• SS7 is a high-speed, reliable data network designed to support the call set-up and

intelligent network needs of the Sprint network.

• SS7 is a basic block required for the Integrated Services Digital Network (ISDN),

and will make possible the addition of an abundance of new features and services

which depend upon SS7 technology. The variety of different services available with

digital networks could not be offered with transparent interconnection without the

use of common channel signaling. SS7 is the signaling system transport mechanism

for ISDN, which has been developed with the ultimate goal of combining all



communications services into a single network to which any customer has access

over common facilities. X

X

Packet-Based Service Delivery

Sprint’s PSS offering, based on the international standard X.25 protocol, is one of the

world’s largest public data networks (PDN). This service, SprintNet, provides an electronic

pipeline over which computers around the world exchange information at high speeds.

Dynamic alternate re-routing, built-in redundancy, and backup services ensure network

availability.

The network also reflects a commitment to using high speed (minimum 56/64 kbps)

digital circuits as the primary path wherever possible, taking full advantage of Sprint’s equity

in major international digital fiber-optic systems.

Dedicated connections between customer sites and the network are monitored to detect

local loop failures, and in the event of a failure, immediate steps are taken to begin remedial

action. SprintNet currently supports over 3,000 host connections and over 3.5 million

computer accesses per day.

The SprintNet PDN uses a combination of digital multiplexers and packet switches to

provide a backbone “data transport platform.” The intelligent portion of the PDN backbone

is derived from Sprint’s fiber-optic network and takes full advantage of its redundant ring

design. The T1 network is used to provide transport services for the SprintNetX.25 PDN. X

XInternational Coverage

Sprint has been formulating alliances, partnerships, and joint ventures on a global basis

since the early 1980s to better serve the needs of our growing base of multinational

customers. To this end, one of the most important partnerships in the telecommunications

industry was launched on February 1, 1996. Sprint, France Telecom, and Deutsche Telekom

developed a global partnership that provides superior and cost effective global

telecommunications services to business, consumer, and carrier markets worldwide. This

partnership became GlobalOne.

Key advantages to conducting international business with Sprint include:



• One Point-of-Contact - Locally based global account managers handle every aspect

of the Government’s international communications requirements, from designing the

service portfolio to answering billing questions.

• One Point-of-Support - 24 hours-a-day, 7 days-a-week, dedicated service agents

are ready to respond to any question or problem.

• One Global Network - State-of-the-art technology means optimum network

performance and availability.

The information systems infrastructure of GlobalOne supports multi-currency and

multilingual billing, consolidated billing and reporting, and global service management—as

befits a truly global company.

XXXXtechnical and customer service operating centers and the processes of Regional

Operating Groups and National Service Organizations are consistently managed to ensure

cost-effective internetworking service in accordance with centrally set GlobalOne standards.

All network and IT operations are conducted by the Regional Operating Groups. When

National Operators act as network extensions for GlobalOne, the maximum degree of

network oversight and integration is sought, to maintain the interworking of services

provided to our customers.

From the very beginning, Sprint through GlobalOne has been able to offer corporate

network services in more than 65 countries using over 1,200 points of presence. Within five

years, this presence will be extended to more than XXXX data nodes in XXX countries.

The Global One Partnership

This joint venture differs significantly from other alliances in many ways, including the

following:

• The charter is broader, covering networking requirements of global business,

consumer, and carrier markets.

• GlobalOne was created to provide a broad range of international services by

integrating the expertise of its three parent companies.



• Each of the three owners has an equal voice in determining the strategic direction of

the enterprise.

Taken separately, Sprint, France Telecom, and Deutsche Telekom already had significant

international and offshore operations aimed at serving the global requirements of medium,

large, and multinational corporations—as well as Government’s. These activities require

global product management, offshore implementation of end-to-end network platforms and

trouble resolution, and out-of-home-country sales and sales support. GlobalOne is the only

global alliance that operates as a single company providing these global platforms under one

roof.

Through this partnership with two of the world’s largest telecommunications companies,

Sprint has become a leader in providing global telecommunications. Sprint’s global presence

effectively addresses the Government’s present and future international telecommunications

needs.

Deutsche Telekom

Deutsche Telekom, with 1996 revenues of more than $(US)40.6 billion, is Europe’s

largest telecommunications operator with 40 million phone lines in service and the world’s

second largest generator of international telecommunications service revenue. As the

national operator of all switched voice, telex, and public telephone services, Deutsche

Telekom acts as the local and long-distance telecommunications provider for the unified

German Republic.

Deutsche Telekom offers a complete range of services and products, both nationally and

internationally, and is at the leading edge of some of the most important telecommunications

developments: ISDN, ATM, and Fiber-to-the-home. Deutsche Telekom has 3 million ISDN

lines in service and 16 million cable TV subscribers. Approximately 2.4 million homes are

currently passed by fiber-optic cable with plans for expansion during 1997 to 5.4 million

homes.

France Telecom



France Telecom, with 1995 revenues of more than $(US)29.6 billion, is Europe’s second

largest carrier and the world’s fourth largest telecommunications provider with 32 million

telephone lines in service. As the national operator of all switched voice, telex, and public

telephone services in France, France Telecom acts as both the local and long-distance

telecommunications provider.

In addition to local and long-distance switched voice, France Telecom provides

businesses and consumers with the full range of voice, data, video, wireless, and cable

television services. France Telecom has been active in the foreign telecommunications

markets for decades and has acquired substantial global experience offering basic telephone

and value-added services. The company is a significant force in the development of

telecommunications networks in several countries.

2.12 International Carriers and Service Providers Performance Standards (L.38.1.1(l))L.38.1.1(l) Discussion of the performance standards associated with the international carriers and service providers the offeror proposes

to use.

Sprint has expanded the reach of our domestic 100 percent fiber-optic network with a

comprehensive array of international facilities designed to offer the Government the highest

XThe Sprint Government Services Division sales and engineering teams will develop

customized solutions that exceed the Governments performance requirements and also

minimize the Governments costs. Every solution will be evaluated based upon traffic

pattern, traffic volume, as well as usage duration. Sprint will minimize the Governments

costs by conducting engineering trade-off studies to determine how to minimize access

charges.

2.14 Approach to Achieve IPS Interoperability (L.38.1.1(o))L.38.1.1(n) Approach to achieve IPS interoperability (see Section L.38.1.3.4).

Sprint will provide interoperability of IPS with Internet and the Federal Government IP

networks through existing connectivity with every Network Access Point (NAP) for Internet

and with both Federal Internet Exchange (FIX) points for the Federal Government IP

networks. These FIXes are located at Moffit Field, CA, and College Park, MD. After

contract award, Sprint will coordinate with the Federal Networking Council for

interconnection standards.

XThe Internet is essentially multiple networks that are linked. The links between

networks are called interconnect points and are gateways between networks, (like Sprint

Internet Access Service), to other National Service Providers (NSPs). The network of

internetworked Internet Service Providers (ISPs), through high-speed interconnect points,

forms the backbone of the Internet. Sprint Internet Access Service continues to maintain as

many Internet Service Provider interconnect points as are reasonably required.X
