AT&T American Telephone & Telegraph
IPP Independent Payphone Provider
LEC Local Exchange Carrier (i.e. Bell Atlantic)
CLEC Competing Local Exchange Carrier
ILEC Incumbent Local Exchange Carrier
IXC Inter Exchange Carrier (I.e. Sprint, AT&T)
COCOT Company Owned Coin Operated Telephone
LD Long Distance (Usually 1+NPA+NPX-XXXX)

0++ Dialing 0, +Phone#, +Credit Card #
0- Dialing 0, and waiting for a live operator
NPA Number Plan Area (a.k.a. Area Code)
NPX Number Plan Exchange
NANP North Atlantic Numbering Plan (all these new
area codes, and confusing dialing patterns) This
is due to all the Pager, Fax, Cellular, and Internet
access lines being added. One paging company
can burn up a whole exchange in a month!
101XXXX The latest dialing patterns for Long Distance
companies. It is not "ten-ten-321", but is
actually "one-zero-one-0321) The original
10XXX (XXX being the carriers id) was not enough
to provide access for new companies entering the
market, so it needed to be expanded.
CAN The enclosure around the payphone!
NID Network Interface Device. That gray box your
phone line comes from.
MPOE Minimum Point Of Entry. Since the LECs are all
damaged we IPPs entered the payphone market,
they charge to put the "NID" where we want it.
MPOE basically means, the easiest, and least
work
needed to install the phone line.
ISDN Integrated Services Digital Network.
This is a digital telephone line, with a 64KBsec
or 128KBsec data rate. Great for internet surfers,
and are now relatively cheap! They can be dial-up
or always-on! You can also have up to two analog
ports for incoming voice calls, very versatile!
T-1 This a 1.5MBsec digital line, still costly, and mainly
for servers. A switch is used to split the T-1 into
a total of 24 separate analog lines.
DSL Digital Subscriber Line. Much faster then the
ISDN line, up to 1.5Mbit, and some places claim
7Mbit. In some cases, these lines are cheaper
than an ISDN line.
ADSL Asymmetric Digital Subscriber Line
