`Facilitate An overly pompous way to say "to make easy” or
`"to make it happen."
`imprecisely defined word that means
`Fauilities A stupid,
`anything and everything. To me it sounds like toilets‘. But its
`not. it can mean the equipment and services which make up a
`telecom system. it can mean offices, factories, and/or build-
`ing.
`It can be anywhere you choose to put telecom things.
`Oops,
`l nearly said telecom facilities. So "facilities" means
`practically anything you want it to mean so long as it covers
`a sufficiently broad variety of “things” which you haven't got
`a convenient name for. "Facilities" sounds better than things,
`especially ifyou want to sound pompous.
`Facilities Administration And Control A PBX fea-
`ture which allows you, the subscriber, to assign to your users
`features and privileges like authorization codes, restriction
`levels and calling privileges.
`Faxilities Assurance Reports This feature allows a
`subscriber to get an audit trail of the referrals produced by the
`automatic circuit assurance feature of some PBXs. The audit
`trail will
`identify the trunk circuit,
`the time of referral, the
`nature of the problem and if a test was performed, the out-
`come of the test.
`Facilities Based Carrier A carrier which owns most of
`its own facilities (i.e., stuff), such as switching equipment and
`transmission lines.
`Facilities based end to end.
`There are three benefits to being a facilities based carrier
`Cheap, roll out new features fast, network integrity.
`facililties based end to end
`lLECs (incumbent Local Exchange Carriers) such as Bell
`Atlantic, BellSouth, Citizens Communications, GTE and SEC
`fit this definition.
`incumbent lXCs (lnterexchange Carriers)
`such as AT&T, MCI Worldcom and Sprint also fit this defini-
`tion. The major facilities—based lXCs have switching offices,
`or POPs (Points OF Presence) in all service areas of the coun—
`try and provide both originating and terminating service
`nationwide. Major facilities—based carriers sell their services
`to business and residential users and to other carriers which
`resell those services. Non facilities—based long distance car-
`riers are known as switchless resellers. To be recognized as a
`CLEC (Competitive Local Exchange Carrier) by most local
`regulatory authorities and to receive reciprocal compensation
`from the local
`ILEC, you must, at minimum, own a central
`office switch; thus you must be a facilities based carrier.
`There’s probably not one single carrier — local,long distance
`or international — in the entire North America that is 100%
`facilities based these days. Everyone seems to be renting
`some facilities — usually lines — from someone else. The
`most facilities based would be the lLECs. The least facilities
`based would be the CLECs (Competitive LECs). They tend to
`resell local loops from the local lLEC which they terminate in
`their switching centers. See also CLEC, lLEC, lXC and POP.

`Remote Access Device RAD. Typically a remote access
`device (also called a Remote Access Server) is a piece of com-
`puter hardware which sits on a corporate LAN and into which
`employees dial to get access to their files and their email. Remote
`access devices are also used by commercial service providers,
`such as lnternet Access Providers (lSPs) to allow their customers
`access into their networks. For longer explanatiolns, see also
`Remote Access Server and Universal Edge Server.
`Remote Access Server RAS. A remote access server
`(also called a Remote Access Device or in a bigger version, a
`Remote Access Concentrator) is a piece of computer hard-
`ware which sits on a corporate LAN and into which employ-
`ees dial on the public switched telephone network to get
`access to their email and to software and data on the corpo-
`rate IAN (e.g. status on customer orders). Remote access
`servers are also used by commercial service providers, such
`as Internet Access Providers (lSPs) to allow their customers
`access into their networks. Remote Access Servers are typi-
`cally measured by how many simultaneous dial—in users (on
`analog or digital lines) they can handle and whether they can
`work with cheaper digital circuits, such as T-1 and E-1 con-
`nections. See also Remote Access Concentrator and
`Universal Edge Server.
`Remote Access Services Software that enable distant
`PCs and workstations to get into a Remote Access Server to
`get to software and data on a corporate LAN. Remote access
`services are provided through modems, analog telephones or
`digital
`ISDN lines. Remote access services is For a much
`longer explanation, see Remote Access (Ref: Hands—0n
`Networking Essentials, M.J. Palmer, Course Technology,
`Cambridge, MA, 1998, p.293)
`Remote Access To PBX Services Allows a user outside
`the PBX to access the PBX by dialing it over a normal phone
`line. You dial the number.
`It answers. It may or may not say
`anything. It mayjust give you dial tone. You now punch in an
`authorization code. If your code is acceptable, the PBX gives
`you another dial tone. That dial tone is effectively the one all
`users within the PBX get. Once you have this dial tone, you
`can dial another extension, jump on the company's WATS net-
`work, get
`into the dictation unit, access its voice mail, or
`whatever. Suffice, you are inside the PBX. You can do what-
`ever anyone else inside the PBX can do.
`Remote Adapted Routing The adaptation of backbone
`routing techniques that take into account; slow—line commu-
`nications links,
`intermittent connections, security, charity
`chatty routing protocols, management, and user ergonomics.
`Remote Batch Processing Processing in a computer
`system in which batch programs and batch data are entered
`from a remote terminal or a remote PC (personal computer)
`over phone lines.
`Remote Bridge A bridge between two or more similar
`networks on remote sites. Dial up or leased lines typically
`require a local bridge or gateway and a remote bridge or
`gateway an each end, in order to network.
`Remote Call Forwarding RCE This is a neat service. It
`allows a customer to have a local telephone number in a dis-
`tant city. Every time someone calls that number, that call is
`forwarded to you in your city. Remote call forwarding is very
`much like call forwarding on a local residential line, except
`that you have no phone, no office and no physical presence in
`that distant city. Remote Call Forwarding exists purely in the
`central office. You can also think of it as measured Foreign
`Exchange. Companies buy Remote Call Forwarding for three
`reasons: 1. To encourage distant customers to call them by
