A VRS (Voice Response System) is a computer system that is called using
|
|
a normal DTMF (Dual-Tone Multi-Frequency) telephone and interacted with
|
|
by speaking or by pressing buttons on the telephone keypad.
|
|
|
|
This article will discuss three such systems which are used by LLC Local
|
|
Loop Carriers (LLCs) to maintain the Public Switched Telephone Network
|
|
(PSTN). The systems are:

Introduction
|
|
~~~~~~~~~~~~
|
|
|
|
The Harris Corporation's DATU Loop Conditioning System combines a full
|
|
range of advanced features with unmatched versatility to help maximize
|
|
field testing and conditioning capabilities. The DATU system extends the
|
|
field technicians testing capabilities of subscriber lines through the
|
|
non-metallic environment of a pair gain system.
|
|
|
|
DATU is a printed wiring card that employs micro-processor control of
|
|
test functions and provides voice prompting. The card is installed in
|
|
the Metallic Facility Terminal (MFT) frame and connected through a
|
|
No-Test trunk to a switching facility. It may be used with most types of
|
|
Central Offices (CO) including SXS, Crossbar, ESS and DMS.
|
|
|
|
The DATU system can include the Pair Gain Applique (PGA) II, located
|
|
with the DATU system at the CO, and the Metallic Access Unit (MAU),
|
|
which is mounted within a remote terminal.
|
|
|
|
PGA units allow testing of subscriber lines being served through an
|
|
SLC-96 pair gain system. The PGA provides an interface between the DATU
|
|
and a Pair Gain Control Unit. The DATU will transmit tones to assist in
|
|
determining the status of the carrier channel. When a subscriber line is
|
|
being served by a pair-gain-system and the DATU is used to test it, a
|
|
warble tone is heard. The warble tone is followed by either a single
|
|
one-second tone, two one-second tones, or three one-second tones. This
|
|
indicates either a single party channel, multi party channel or a coin
|
|
channel. The absence of a tone indicates trouble with the channel or
|
|
channel equipment.
|
|
|
|
|
|
Features
|
|
~~~~~~~~
|
|
|
|
AUDIO MONITOR - The subscriber line may be monitored for up to 10
|
|
minutes, after which time the DATU disconnects from the No-Test trunk.
|
|
Audio Monitor may be used on either busy or idle lines. Traffic on a
|
|
busy line will be audible but unintelligible. The Audio Monitor Mode may
|
|
be exited before the end of the 10 minute period by selecting an
|
|
appropriate test function.
|
|
|
|
OPEN LINE - Opens subscriber line by removing battery and ground.
|
|
|
|
SHORT LINE - A metallic short is placed across the tip and ring of the
|
|
subscriber line.
|
|
|
|
SHORT TO GROUND - A metallic connection between tip, ring, and ground.
|
|
This feature is not available on a busy line.
|
|
|
|
TIP TO GROUND - A metallic connection between tip and ground with the
|
|
ring open.
|
|
|
|
RING TO GROUND - A metallic connection between ring and ground with the
|
|
tip open.
|
|
|
|
HIGH LEVEL TEST TONE - A high level 577Hz metallic-tracing tone,
|
|
interrupted four times per second, for identity purposes. The High Level
|
|
Test Tone is not available on a busy line.
|
|
|
|
HIGH LEVEL TONE ON TIP - Test tone is placed only on the tip side of the
|
|
line, with the ring side grounded.
|
|
|
|
HIGH LEVEL TONE ON RING - Test tone is placed only on the ring side of
|
|
the line, with the tip side grounded.
|
|
|
|
LOW LEVEL TEST TONE - A low level 577Hz simplex-tracing tone,
|
|
interrupted four times per second, for identity purposes. The Low Level
|
|
Test Tone may be applied even if the line under test is busy, and it
|
|
will not disturb traffic on that line. Note that on some No.5 ESS
|
|
switches, Simplex tone may not transmit.
|
|
|
|
SINGLE LINE ACCESS - Allows conditioning functions on the same line used
|
|
to access the DATU system.
|
|
|
|
HOLD - Used to continue a line preparation function after disconnecting
|
|
from the system's access line.
|
|
|
|
FORCED DISCONNECT - Allows the technician to disconnect from the system
|
|
at any time by dialing ##.
|
|
|
|
ADMINISTRATIVE - Password protection for both user and administrator
|
|
modes of access. System usage counters and timers are accessible through
|
|
interactive voice response.

|
|
|
|
|
|
Small Office Loop Testing System (SOLTS) is a system used by telephone
|
|
company field repair personnel to test a phone line from any touch-tone
|
|
telephone.
|
|
|
|
When dialing a SOLTS number, the first prompt is:
|
|
|
|
~Please enter ID, terminate with #~
|
|
|
|
SOLTS allows 30 seconds to enter a correct ID, then prompts:
|
|
|
|
~Please enter line number and press #~
|
|
|
|
SOLTS allows 60 seconds to enter a line number, then prompts:
|
|
|
|
~Select mode, for help enter 0~
|
|
|
|
SOLTS allows 60 seconds to choose one of six options:
|
|
|
|
|
|
Enter:
|
|
|
|
1) Interactive Testing
|
|
2) Calling on test line
|
|
3) Retrieve results
|
|
8) Hang up
|
|
9) Enter line number
|
|
0) Help
|
|
|
|
|
|
Option one allows testing the telephone line connected to the number
|
|
entered in step two above. Option two tests the line the technician is
|
|
calling from. Option three is used to retrieve the results generated
|
|
using options one and two. Option eight disconnects from the system.
|
|
Option nine allows a new line number to be entered for testing. Option
|
|
zero accesses on-line help.

When calling FAST, the first prompt is a request for a security code.
|
|
The security code is usually the employee badge number. After the
|
|
security code is entered and the # key is pressed, FAST will prompt for
|
|
the password. The password is usually 4-7 digits long and usually
|
|
expires every 30 days. The default password is usually the security
|
|
code. After the password is entered and the # key is pressed the FAST
|
|
New Notices and Features are played.
|
|
|
|
After all of that, the FAST Main Menu is made available:

Voice Response Systems can be a great deal of fun, and they can be
|
|
safely accessed from a public telephone. Don't play with these from
|
|
home. VRSs are a great way to hack without using a computer.
