Description

The TSA 6000 is a powerful Telephone and Terminal Adaptor System Analyzer. It is comprised of 2 parts. The Hardware component, either a TSA 6000 tm which is a stand alone unit that captures the signals to on-board Flash memory or a TSA 6000 - USB which uses a full speed usb interface and captures the signals directly to a personal computer. The TSA 6000 and TSA 6000 USB are easy to use and knowledge of telephony or Caller ID is not required. For the TSA 6000, data is transferred to a host PC for analysis by the TSA 6000 Software via the serial port or on board V.90 modem. Once the data is transferred, pressing a single button will completely analyze the captured signal. The Software component has many features for viewing and manipulating the captured signal including FFT and filtering functions. The TSA 6000 is valuable for trouble shooting CPE, Network, DLC or CO problems.

The TSA 6000 completely analyzes and trouble shoots the analog side of VoIP and Set Top Box / Cable modem terminal adaptors.

The TSA 6000 and TSA 6000 - USB are FCC, CSA C/US and CE certified.

Software

The following examples illustrate some features of the TSA 6000 analysis software. The display is divided into two main areas; the upper portion is the AC coupled signal and the lower portion displays the low frequency or DC coupled signal. Once the signal is analyzed all detected signals are displayed in the "hit line" along the top of each window. The hit line is context senstive and will display more information as you zoom. For example, you can zoom in on an FSK signal until you see the bit level information including individual start, stop, stuffed mark and data bits.

1. Type 1 Caller ID with 10dB Twist

Type 1 Caller ID with 10dB Twist

Signal capture of a Type 1 (on hook) FSK Caller ID transmission preceded by power ringing. The FSK has 10dB of twist.

2. Type 1 Caller ID with 10dB Twist FSK Details Window

Double clicking any of the detected signals that are identified in the hit line will bring up a dialog box of parametric information. In this case the FSK dialog box indicates the 10dB of FSK twist on the signal.

3. Type 2 Caller ID Transmission with EIU Check

Type 2 Caller ID Transmission with EIU Check

Signal capture of a Type 2 (off hook) FSK Caller ID transmission with the CPE going on hook after the CAS tone to do an EIU (Extension in Use) check.

4. Type 2 Caller ID Zoomed In View of FSK Signalling

Zooming on the FSK portion of the signal displays the Caller ID format down to the bit level. In this case you can see the start, stop and data bits. There were no framing errors or stuffed mark bits in this signal.

5. Type 2 Caller ID Transmission with Multiple OSI

Type 2 Caller ID Transmission with Multiple OSI

Signal capture of a Type 2 (off hook) FSK Caller ID transmission with CO (central office) generated OSI's (open switch intervals) The DC coupled channel identifies the periods where the battery voltage is removed as OSI's. There was an OSI preceding the SAS tone and following the FSK transmission.

6. CAS Tone Details Window

Double clicking the CAS hit shows that the CAS tone had a 10dB twist. The high frequency tone at 2750Hz was right near the TIA specication limit of -32dBm. The FFT shows that there were no significant interference tones present.

CAS Tone Details Window

7. CAS Tone FFT Window

CAS Tone FFT Window

Double clicking the CAS hit and pressing the FFT button displays a Hanning windowed FFT and shows that the CAS tone had a 10dB twist. The high frequency tone at 2750Hz was right near the TIA specication limit of -32dBm. The FFT shows that there were no significant interference tones present.

8. FSK Details Window with Multiple Impairments

Double clicking the FSK hit shows that the FSK had a low baud rate (1188bps) and Mark frequency (1140Hz) and a high Space frequency (2278Hz) and an FSK twist of -2.1dB. The red box clearly identifies signal that are out of specification. In this case the Mark frequency is out of specification.

9. Zoomed In View of FSK Signalling with Stuffed Mark

Zoomed In View of FSK Signalling with Stuffed Mark

Signal capture of a low level FSK transmission with stuffed mark. This zoomed image shows the stuffed mark between each byte of data.

10. FSK Details Window of FSK with Stuffed Mark

Double clicking on the FSK hit shows that the FSK transmission level was -42.1dBm and that there was stuffed mark present. There was no signal dropout in the channel seizure or mark premable.

11. Outgoing Call with Stutter Dialtone

Outgoing Call with Stutter Dialtone

Signal capture of an outbound call with SDT (stutter dialtone) In this case the DC coupled channel shows the line condition as it transitions from idle to terminated and back to idle state. The AC channel displayes the SDT presented on the line, followed by DTMF dialing and ringback tone.

12. FSK Transmission with Large 60 Hz Noise Component

Signal capture of an FSK Caller ID transmission with a strong 60Hz noise component. In this case the FSK is modulated by the 60Hz tone.

13. FSK Transmission with Large 60 Hz Noise Low Pass Filter View

FSK Transmission with Large 60 Hz Noise Low Pass Filter View

The powerful TSA software allows the data to be manipulated after a signal is captured. This image shows the same data above with a low pass filter applied. The 60Hz noise is now plainly evident.

14. FSK Transmission with Large 60 Hz Noise Band Pass Filter View

Shows the same signal with a bandpass filter applied. The FSK can now be plainly viewed without the interference tone. This is useful to determine if the data portion of the signal is within specification independant of the interference tone.

Hardware

TSA 6000

Signals can be easily captured using a single Start/Stop button. There are also advanced triggering functions for capturing signals. All signals on the telephone line are recorded. This includes signals such as On hook transistions, Offhook transitions, OSI's, Line Reversals, Call Waiting extension in use checks, Voice, DTMF, Call Progress tones, FSK for Caller ID, CAS, SAS, DTAS and any other voice band signal.

The TSA uses multiple 16 bit Analog to Digital converters and a lossless compression scheme to minimize file size. Files are stored locally on a 256Mbit FLASH. Files that have been captured are listed in the File menu and can be played back locally.

Files are transferred to the TSA software via the serial port or the V.90 modem.

The TSA has a VoiceNote feature that allows an "audio tag" to be attached to any data file. This is useful for recording particulars of any data. The VoiceNote is transferred to the TSA software along with the data file and can be played back locally or on the PC. This eliminates the need to transfer hastily written notes from a trouble site to the point of analysis. VoiceNotes also provide permanent records of where the file was recorded, what the suspected problem was and what equipment was being tested.

TSA 6000 - USB

Designed in part by customer feedback, the TSA 6000 - USB is a compact budget sensitive version of the original TSA 6000 tm. By taking advantage of new technology, the cost was reduced without leaving behind any of the features that made the original TSA 6000 tm the most sought after line capturing equipment on the market.

Still included is the full Telephone Signal Analyzer software. Enhanced to work with the full speed usb unit you no longer wait to transfer captures between the unit as all captures are transfered automatically as they are recorded.


Accessories

The custom TSA 6000 thermo-formed, high-density polyethylene shipping containers meet the Air Transport Association's(ATA) Specification 300, Category 1 requirements. The TSA 6000 professional travel cases have a 2" thick lining of polyurethane foam cushioning on all sides, top, and bottom as well as a hinged lid.

Other features include tongue-and-groove valance, rubber gaskets to seal out dirt and moisture, full length heavy-duty piano hinges, quarter-turn military-style latches, spring-loaded handles and all cases can be padlocked.
