| Dial |
To
Place A Call On A Switched Network. The term "dial" is obsolete
- based on rotary dial phones and electromechanical relay switches
(which are nearly non-existent in modern telephone systems.)
Touch Tone service recognizes dual tones that are generated
as each telephone key is pressed. Where Touch Tone service is
not available, telephones and switches electronically "pulse"
signals that emulate the older rotary dial telephones. The terms
"place" a call or "originate" a call are more accurate than
"dial". |
| Dial
Tone |

at a central office, a dial tone signal is sent to the originating
caller on a switched network to indicate that the switch is

| Digital |
A
device or method that uses discrete variations in voltage, frequency,
amplitude, location, etc. to encode, process, or carry binary
(zero or one) signals for sound, video, computer data or other
information. For example, a digital clock displays the time
as discrete numeric values, rather than angular displacement
of analog hands. Digital communications technology generally
permits higher speeds of transmission with a lower error rate
than can be achieved with analog technology. When analog signals
are received and amplified at each repeater station, any noise
is also amplified. A digital signal, however, is detected and
regenerated (not amplified). Unlike amplification, any noise
(less than a valid signal) is eliminated by digital regeneration. |
| Directory
Assistance - DA |

the telephone number(s) they wish to call. |
| Equal
Access |
(AT&T
Divestiture - 1982 Modified Final Judgement) The provision of
one-plus capability to interLATA competitors of AT&T. Customers
should be able to reach the carrier of their choice by dialing
1+ the long-distance number. The MFJ and the FCC require local
exchange carriers to provide equal access (most central offices
now have this capability). Equal Access may also refer to a
more generic concept under which the BOCs must provide access
services to AT&T's competitors that are equivalent to those
provided to AT&T. |
