Packet Switching

US: The FCC defines packet switching as the function (including the necessary electronics, such as routers and Digital Subscriber Line Access Multiplexers (DSLAMs)) of routing individual data units, or 'packets,' over a network based on address or other routing information contained in the packets themselves.

Pay-Per-Call Services

US: Also commonly known as '900 services,' pay-per-call services offer telephone callers a variety of recorded and interactive information and entertainment programs that carry charges greater than, or in addition to, the charge for transmitting the call, and are available through 900 numbers. (See also '900' Telephone Service)

 
 

Pay Phone Service Providers (PSP)

US: Independent and local exchange carriers who provide pay phone services, usually in public areas. In the '96 Act `payphone service' is defined as the provision of public or semi-public pay telephones, the provision of inmate telephone service in correctional institutions, and any ancillary services. [See also CI '96 Act Reference I(151)(276)(d)]

PEG (Public, Educational, Governmental) Access (PEG)

US: A provision of the Communications Act of 1934 that permits local cable television franchising authorities to establish requirements in a cable TV franchise for the designation or use of channel capacity for public, educational, or governmental use. [See Communications Act of 1934, Section 611 (Cable Channels for Public, Educational, or Governmental Use).]

 
 

Pen register

US: A device used in law enforcement that captures call-identifying information for numbers dialed from the facility that is the subject of lawful interception (i.e. outgoing calls).

PIC-Change Charge (Pre-subscribed Interexchange Carrier-Change Charge)

US: A fee that local telephone companies charge a customer when the customer decides to change the long distance telephone company to which he or she is pre-subscribed. The FCC established a $5.00 cap for this charge in 1984 and began a review of its policies on the PIC-change charge in March 2002 (see US Rep 32, III.A).

 

Play or Pay

US: The "play or pay" system, adopted by the State of New York, is a system in which new entrants who interconnect with the incumbent local exchange carrier agree to serve all customers in their self-defined service areas ("players") potentially paying a substantially lower interconnection rate than those that serve only selected customers ("payers") who are liable to pay additional interconnection rates or contribution charges. (CC Docket 96-98)

 

Point of Presence (POP)

US: An IXC (interexchange carrier) switching facility located within the local exchange area of an incumbent local exchange carrier (ILEC) through which interexchange traffic is routed to and from the IXC's end customer over the local facilities of the LEC. Point of presence also refers to the facilities of a competing local carrier located within the local exchange area of an ILEC.

 
 

Pole Attachment

US: Any attachment by a cable television system or provider of telecommunications service to a pole, duct, conduit, or right-of-way owned or controlled by a utility. (Communications Act of 1934, as amended - 47 U.S.C. 224(a)(4))

Pre-Ordering and Ordering

US: In the context of operations support systems (OSS) used by incumbents local exchange carriers to provide information and services to competitive entrants, pre-ordering and ordering includes the exchange of information between the carriers about: current or proposed customer products and services; or unbundled network elements, or some combination thereof. This information includes loop qualification information, such as the composition of the loop material, including but not limited to: fiber optics or copper; the existence, location and type of any electronic or other equipment on the loop, including but not limited to, digital loop carrier or other remote concentration devices, feeder-distribution interfaces; the loop length, including the length and location of each type of transmission media; the wire gauge(s) of the loop; and the electrical parameters of the loop, which may determine the suitability of the loop for various technologies.

Presubscribed Interexchange Carrier (PIC)

US: The interexchange carrier selected by a telephone subscriber as the primary long distance company whose network is directly accessed by the subscriber when dialing "1" plus the area code and telephone number of the called party. Once selected, subscribers may "dial around" the PIC by using the carrier access code of another interexchange carrier on a call-by-call basis.

 
 

Pre-subscribed Interexchange Carrier-Change Charge (PIC-Change Charge)

US: A fee that local telephone companies charge a customer when the customer decides to change the long distance telephone company to which he or she is pre-subscribed. The FCC established a $5.00 cap for this charge in 1984 and began a review of its policies on the PIC-change charge in March 2002 (see US Rep 32, III.A).

Presubscribed Interexchange Carrier Charge (PICC)

US: Prior to its elimination by the FCC in May 2000 as part of a broader access charge reform package (see US Rep 21, II.B.), the PICC was a flat-rate, per-line access charge assessed by local exchange carriers (LECs) on a subscriber's presubscribed interexchange carrier (PIC) that goes to the LEC to defray that part of the cost of a subscriber's local loop assigned to the interstate jurisdiction and not recovered by the end-user subscriber line charge (SLC). Where an end user declines to select a PIC, the PIC charge will be assessed on the end user. The PICC was first established by the FCC in its May 1997 Access Charge Order to replace over time the per-minute carrier common line charge (CCLC), which is considered inefficient because it recovers a fixed (loop) cost from a usage-sensitive charge. The PICC took effect on January 1, 1998. [See also Access Charges, CCLC, PIC, SLC]

Price Cap Regulation

A form of rate (price) regulation that permits rates to increase by no more than the "price cap index," or PCI, a measure of general inflation minus an "X-Factor" that largely reflects a reasonable productivity target. The higher the X-Factor, the more downward pressure price cap regulation applies to rates. Traditionally, the X-Factor represented the amount by which carrier productivity had historically exceeded productivity in the economy generally. In 1990, the FCC adopted mandatory price cap regulation for the Bell Operating Companies and GTE for calculating access charges to be paid to them by long distance carriers and subscribers for use of the local network to originate and terminate long distance calls. When the FCC reformed its access charge rules in May 2000 (see US Rep 21, II.B.) it decided that the X-factor used by ILECs to calculate access charges would no longer be based on assumed growth in productivity, but would be deliberately set to reduce access charges at a certain pace. Smaller local exchange carriers remain under rate-of-return regulation but may elect to be governed by price cap regulation.
The price cap rules divide incumbent LEC services among four baskets, with each basket being subject to a separate price cap index (PCI). Price cap ILECs serve more than 92 percent of the total subscriber lines in the country, accounting for approximately 91 percent of the revenues. (See also Access Charges and Rate-of-Return Regulation)

Private Branch Exchange (PBX)

US: A multi-line electronic telephone switching exchange located on the premises of the customer that acts as a branch of the telephone company's local central office for the private use of the customer. Compare Centrex, which is the use of the switching system at the local central office as if it were a PBX.

Private Carrier

US: In general, a private carrier is a service provider who may choose its clients on an individual basis, determining in each particular case whether and on what terms to serve, and may design its system to meet its own communications needs rather than those of its customers.

The terms and conditions of a carrier's particular service and the way it holds itself out to the public are the key determinants as to whether a carrier is a 'common' or 'private' carrier.

A 'common carrier' must provide a service indifferently to all potential customers, and that service must enable customers to transmit intelligence of their own design and choosing. A 'private carrier' has no such obligations.

Indicative of private carriage are: (1) lack of a legal compulsion to serve the public indiscriminately; (2) insignificant carrier market power; (3) medium-to-long range service contracts that ensure a relatively stable clientele, and (4) contracts tailored to the particular needs of the carrier's customers.

Unlike common carriers, private carriers are not required to secure authorization from the FCC to provide their services under Section 214 (Extension of Lines) of the Communications Act of 1934, as amended. (see also Common Carrier)

Proportionate Return Requirement

US: One of three principal components of the FCC's international settlements policy (ISP) which requires U.S. carriers to receive from a foreign country the same share of inbound IMTS traffic to the U.S. as they send outbound to that country. (IMTS is international message telephone service)

US: An advisory committee sponsored by the FCC and the National Telecommunications and Information Administration (NTIA) of the US Department of Commerce which was established to provide advice and recommendations regarding the specific communications needs of public safety agencies. PSWAC was established in the wake of the Budget Act of 1993 in which the US Congress required the FCC to develop a framework to ensure that public safety communications needs are met through the year 2010.

 
 


 

Public Telecommunications Network Interconnectivity

US: As used in the Telecommunications Act of 1996, the term `public telecommunications network interconnectivity' means the ability of two or more public telecommunications networks used to provide telecommunications service to communicate and exchange information without degeneration, and to interact in concert with one another. [See also CI '96 Act Reference I(101)(256)(d)]
