*Calling Card Secrets*
This is an actual document from BELL LABS and is presented by P-80 systems and
is presented in its entirety!!!
CARD-READING PUBLIC STATIONS REQUIREMENTS
Bell Communications Research, Inc.
1. This document describes generic requirements for card-reading public
telephone stations. These stations will be deployed by a Bell Operating Company
(BOC) primarily to provide customers having magnetic-stripe cards with easier
access to both BOC and inter-LATA carrier (IC) facilities.
A BOC Card-Reading Public Station (alternatively referred to as "station") is
intended to work similarly to a current Charge-a-Call station with features
added to read a magnetic-stripe card and conveniently select an IC. The BOCs
expect to issue Calling Cards for use in making intra-LATA toll and local calls
over the BOC networks, and inter-LATA calls over any carrier capable of
accepting a Calling Card number. Similarly, calls billed via Commercial Credit
Cards (CCC) would be possible if the involved BOC or IC were able to accept
them.
1.1 Outline of Document
Section 1.2 describes the scope of the document. The general operation of the
station is described in section 1.3.
Section 2 specifies the requirements for a card-reading public telephone
station. Section 2.1 sets the requirements for card presentation, including how
and when the card should be presented, and what the station should do if the
presentation of the card differs from that required.
Section 2.2 specifies the requirements for signaling by the customer. This
includes acceptable dialed destination numbers, methods of selection of the IC,
and anti-fraud features of the station.
Section 2.3 specifies the requirements on how the station will interface with
the end (local) office. The features of the line and electrical characteristics
are described.
Section 2.4 describes the interface between the station and the IC or a
processor. This includes description of the access environment and what the
station should do to help set up calls.
Section 2.5 specifies the physical characteristics of the station. Section 3
contains requirements pertaining to the support that the supplier should
provide for these stations.
1.2 Scope of Document
This document provides functional requirements for a card-reading, non-coin
public station. The requirements are intended to describe what the station does
in its various interactions with the customer, the local office, and the
carrier of choice or an associated processor. The requirements also describe
the physical environment in which the station operates. This document is not
intended to dictate how given functions are specifically realized.
Card reading transactions described here are limited to magnetic-stripe card
technology and cover only those actions required to set up and properly bill a
call. These requirements are generally limited to the station itself. Actions
by other facilities to provide public calling via credit cards are included
only insofar as they relate to pertinent station functions.
This document contains requirements primarily concerning public stations, card
reading, and carrier selection. The station should also meet requirements
specified by the FCC Rules regarding registration of telephone sets (Part 68),
FCC Rules regarding radiated emissions (Part 15), requirements concerning the
normal station to network interface, and requirements concerning abnormal
conditions on the local loop.
Human factors of the station and the related service have not been, for the
most part, specifically addressed. Good human factors design, however, is
crucial to a successful product, and underlies many of the requirements.
1.3 General Operation of the Station
This document describes a station similar to Charge-a-Call stations, with
features added to read a magnetic-stripe card and conveniently select an IC to
handle the call. This station needs to provide four basic functions:
Voice-band transmission and reception,
Addressing the far end party,
Selection of a carrier,
Relaying appro
