Telecommunications Service Providers: A Guide

The major difference among carriers is whether they arewireless or wireline operators. Some carriers specialize inone service, but many wireline companies overlap in thatthey have units or subsidiaries that operate in the wirelessmarket. These companies are grouped in the wireline cate-gory, since that still forms the primary component of theirbusiness. The wireless companies can be further dividedbetween those providing mobile telephony and those offer-ing paging services. Some wireless providers offer bothmobile telephony and paging.

We have put telecommunications service providers into oneof seven categories, and in some cases more than one cate-gory. Throughout the world, the names of the categoriesmay differ, but the fundamental qualities of those inhabitingthat realm of the telecom market are the same. The sevencategories are: incumbent local exchange carrier, incumbentlong distance carrier, competitive local exchange carrier,long haul fiber provider, competitive international carrier,wireless phone carrier, and paging services companies.

Incumbent carriers are those that have been in the marketfor a long period of time. Typically, they were monopolylicensed and often run by the state. This is changing asthese state-owned incumbents are privatized and regulatorsloosen their monopolistic hold.

The incumbents can be further divided between local ex-change carriers and long distance carriers. Incumbent localexchange carriers (ILECs) held (and, in some cases, stillhold) the dominant position in the local calling market. Inmost markets, this dominant position is being eroded by theentrance of competitors. Like the dominant local players,the incumbent long distance carriers once (and often still do)held a dominant or monopolistic position. Long distancecarriers, regardless of whether they are incumbents or not,are considered to be interexchange carriers (IXCs). Unlessthey simply resell another IXC’s lines, interexchange carri-ers own the switching and transmission equipment (fiberoptic cables, microwave towers, multiplexing equipment,and switches) that carry long distance calls. In many mar-kets, the state-run monopoly in the local market is the samestate-run monopoly in the long distance market. Both localand long distance incumbents are being threatened by whatwe have termed alternative carriers.

Alternative carriers are the new entrants to the telecom mar-kets. Through deregulation, or the breakup of monopolyplayers, potential profit opportunities have been opened up.New entrants have seized upon this opportunity and are en-tering the global telecom markets. The rapidity with whichthey are entering varies across regions, depending on theregulatory status of the market. Alternative carriers have

typically entered the telecom markets in one of three areas:local, long distance, or international long distance.

Competitive local exchange carriers (CLECs) are new en-trants in the local market, directly challenging the incum-bent local provider. They mount a challenge typicallythrough one of three strategies. First, a local competitormay simply resell the incumbent’s service. Resale typicallyresults in slim margins. In addition, the reseller is depend-ent on the incumbent. Second, a local competitor may in-stall some of its own equipment, giving it slightly highermargins and a bit more independence from the incumbent.Third, a local competitor may build out its own facilities.This strategy requires a great deal of capital expenditures,but offers the greatest margins and independence from theincumbent carrier.

Another type of alternative carrier is the long haul fiber pro-vider in the long distance market. Fiber providers challengethe incumbent long distance providers by constructing their

own lines. Fiber providers may simply lay fiber optic linesand sell them to interexchange carriers, they may lay linesand resell service from IXCs, or they may lay lines and offertheir own service over these lines. The huge growth in datatraffic has caused an explosion in the long haul fiber pro-vider market, as competitors rush to meet demand expecta-tions.

The third type of alternative carrier is the competitive inter-national carrier. These competitors challenge the traditionalinternational long distance companies (which are usually thelargest of the incumbent domestic long distance carriers).Typically, competitive international carriers run lines be-tween countries or continents. Like the long haul fiber pro-viders, competitive international carriers may simply sell thefiber they have installed, or they may offer telephone serv-ice over their lines. When offering service, they typicallymake their profit from the tariff differentials between coun-tries.

Access Charge: Fee paid by long distance carriers to localtelephone companies for use of local facilities; amount paidby telephone subscribers to obtain access to local networks.

Access Line: Circuit between a subscriber and a switchingcenter.

Active: Using electricity for generation or regeneration ofsignals. See “passive.”

ADSL (Asymmetric Digital Subscriber Line): A memberof the digital subscriber line family of copper loop enhanc-ing technologies (see “DSL”), ADSL is asymmetric, mean-ing that it provides faster transmission rates downstreamthan upstream. It is therefore well suited to fast Internetaccess, where requests for Web pages and e-mail sent gen-erally require less bandwidth than the receipt of multimediaand Web pages. ADSL is not well suited for business appli-cations that require symmetric communication, such asvideoconferencing and two-way file transfer.

Adjacent Channel Interference: Refers to interferencecaused by the energy from a transmitting channel spillingover into an adjacent channel.

Advanced Intelligent Network (AIN): An advanced ar-chitecture for a telephone network. Its foundations are builton the evolution of computer-based switches and SignalingSystem 7.

Alert: Constant 10 KHz signaling tone sent on the reversevoice channel (by the mobile), in an analog conversation,while the mobile phone is ringing.

All-optical networks: Networks that are entirely optical,and therefore avoid the cost and time delays inherent inconverting optical signals to electric signals and vice versa.

Alphanumeric: A message or other type of readout con-taining both letters (“alphas”) and numbers (“numerics”). Incellular, “alphanumeric memory dial” is a special type ofdial-from-memory option that displays both the name of theindividual and that individual’s phone number on the cellu-lar phone handset.

Alternate Access Carriers: Local exchange carriers indirect competition with the regional Bell operating compa-nies (RBOCs). Normally found only in the larger metro-politan areas.

Alternative Operator Services: Operator services pro-vided by an authorized company other than a local exchangecarrier, regional Bell operating company, or AT&T.

AM (Amplitude Modulation): The simplest carriermodulation technique, where the radio frequency carrier’samplitude envelope is modulated.

AMPS: Advanced mobile phone system. The current ana-log cellular FM system in North America. It uses 30 KHzchannels, and signaling is done superaudio.

Analog: The traditional method of modulating radio signalsso that they can carry information. Analog signals aremeasured by their frequency, or, the number of times persecond that an electromagnetic wave swings back and forthin a complete cycle. The higher the speed/frequency, themore cycles of waves are completed in a period of time.This speed is measured in hertz (Hz).

ARPU (Average Revenue Per User): A primary elementof valuation and analysis of wireless companies. It reflectsthe average amount of revenue generated by each sub-scriber.

Asynchronous Transmission: Mode of data communica-tions transmission in which time intervals between trans-mitted characters may be of unequal length.

number identification (ANI) information from carrier tocarrier, or from carrier to customer.

Packet Switching: The method used to transmit data ondata networks. Unlike the public switched telephone net-work, packet-switched networks do not reserve a circuitbetween end points. Instead, they break up messages orfiles into many small packets. Each message packet maytake a different route from origin to destination, travelingalong network circuits that are shared with packets fromother messages.

Passive: without using electricity. Passive components in-clude splitters and isolators. A key goal of the fiber opticindustry is to increase penetration of passive components,because they do not require power, are reliable, and arefaster than active components because they stay within theoptical realm.

PBX (Private Branch Exchange): A switching systemwithin an office building that allows calls from outside to berouted directly to the individual instead of through a centralnumber.

PDM (Packet Division Multiplexing): Different applica-tions are assigned to different packets within the messageframe, instead of different time slots, as with TDM.

RADSL automatically adjusts line speed based on thecondition of the line. In areas where there is a large vari-ance in the distance between the central office and the sub-scriber, RADSL helps to provide a more consistent servicefor subscribers.

RBOCS (Regional Bell Operating Companies): Localexchange carriers. The seven regional Bell operating com-panies formed as a result of the breakup of AT&T. EachRBOC was granted a distinct geographic territory, or localaccess transport area (LATA), in which they could operate.Ameritech, Bell Atlantic, BellSouth, NYNEX, Pacific Tele-sis, Southwestern Bell Communications (SBC), and U.S.West retained the Bell logo and the right to sell local andtoll calling within the LATA.

SDH (Sychronous Digital Hierarchy): A set of fiber opticcommunication standards, similar to SONET but establishedby the ITU (International Telecommunication Union).

SONET (Synchronous Optical NETwork): A fiber opticcommunications standard established by the American Na-tional Standards Institute (ANSI) that covers multiple datatransfer rates from 51.84 Mbps to 13.22 Gbps. It defines aphysical interface, optical line rates known as Optical Car-rier (OC) signals, frame format, and an OAM&P (opera-tions, administration, maintenance, and provisioning) proto-col.

Special Access Services: The lease of private dedicatedtelecommunications lines or “circuits” along the network ofa LEC or a CAP, to which lines or circuits run from the longdistance carrier’s point of presence.

TDMA (Time Division Multiple Access): A form of mul-tiplexing in which different packets of data are assigned todifferent time slots, allowing for much greater transmissionspeeds.

Telecommunications Act of 1996: The primary focus ofthis legislation is laying out guidelines for opening up com-petition in the local market.

Telecommunications Relay Service (TRS): Provideshearing-impaired individuals the ability to communicatewith others via 800 access using a telephone or terminal.

Telco: A telephone company.

TCP (Transmission Control Protocol): Data applicationprotocol used on the Internet to automatically retransmitpackets that are lost during transmission.

Total Service Resale: A strategy used to enter the localmarket. It is the resale of all of the incumbent’s services.The competitive entrant uses none of its own equipment;rather, it relies entirely on the incumbent — typically, oneof the RBOCs. The competitor leases the lines that theRBOC already has in place. Since it leases a large numberof these lines, it receives a discount from the RBOCs, whichis passed on to customers.

Trunk: Group of circuits that carry call traffic in and out ofthe switch.

Trunk Line: Interexchange carrier lines that carry trafficbetween their points of presence.

Unbundled Access: As laid out in the Telecom Act of1996, unbundled access allows competitors to purchase onlythe pieces of the regional Bell operating companies’ net-work services that they need to provide local service.

The USFis funded primarily by monthly customer fees charged tolong distance carriers and local carriers in more urban areas.The Federal Communications Commission administers thefund, distributing funds on a monthly basis based on thecost of providing local service. The FCC has committed tothis methodology until 2001.

Universal Service Subsidies: Government-granted subsi-dies for providing rural service.

Upstream Transmission: The transmission from a con-sumer’s home or office to the network.

Value-Added Network (VAN): Data transmission networkthat routes messages according to available paths. Assuresthat messages are received as sent; provides user security,high-speed transmission, and conferencing among terminals.

VDSL (Very high rate Digital Subscriber Line): A mem-ber of the DSL family of copper loop enhancing technolo-gies (see “DSL”), VDSL is envisaged as the fastest coppertransmission technology for the local loop. While VDSLprotocols have yet to be standardized, it is likely that VDSL

will be symmetric and suitable only for shorter distancesthan ADSL (asymmetric digital subscriber line). VDSL,ADSL, and FTTH will likely coexist with each other andcable modems as broadband access technologies.

Virtual Collocation: An alternative to physical collocationin which the CAPs connect their equipment to the LECs’facilities from a remote location and request that the LECinstall the necessary electronics in its central office, which isthen leased by the LEC to the CAP for charges generallyhigher than the charges for physical collocation.

VPN (Virtual Private Network): A private network deliv-ered over a service provider’s shared infrastructure.

Voice Grade Equivalent Circuit: One DS-0. One voicegrade equivalent circuit is equal to 64 kilobits of bandwidth.
