- 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:
-
- . DATU
- . SOLTS
- . FAST

- 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.
-

- + +
- + (SOLTS) +
- +----------------------------------+
-
-
- 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

- 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.

- 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.

- 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.
