How Carrier Access Billing Came To Be
Before divestiture in 1983, a
flat amount per call was allotted to the non-Bell companies as part of their
settlement for provision of service to the end-user. This flat compensation
did not take into consideration the type of facilities provisioned to the
specific end-user, the distance the traffic had to travel to the POI, the
length of the call, and/or the route traveled. Because divestiture invalidated
the previous settlement structure, and because of the increasing number and
complexity of the services that LECs (Local Exchange Carriers) provide, there
had to be a way of appropriately compensating the local telephone company for
providing facilities to the user.
Thus, as part of the Modified Final Judgment of 1983, the Federal
Communications Commission mandated access charges. One of those access charges
is the Carrier Access Charge to long distance companies that connect to the
LEC network. This charge enables local telephone companies (LECs) to partially
recover the cost of the “local loop,” which refers to the the outside
telephone wires, underground conduit, telephone poles, and other facilities
that link each telephone customer to the telephone network. (LECs also assess
flat monthly charges to the end users.)
The original model for an access tariff was written by a group of staff from
AT&T to take criteria such as switching, the traffic route, tandem
functions, and minutes of use into consideration for local compensation, as
well as other, more technical data. The Access documents were written and
revised a number of times before their final release in 1983. On January 1,
1984, the right to bill for access was mandated.
