5VF TIMS Module
1 VF TIMS Module
The SSMTT-6B module is a VF TIMS (Voice Frequency - Trans-
mission Impairment Measurement Set) designed for testing,installation, and maintenance of 2 and 4 wire voice circuits. Itsupports the voiceband frequency range from 20 Hz to 20 kHz.Basic TIMS measurements include:
Level/frequency
Noise with tone measurement 3-tone slope or programmable frequency sweep generation
3-level impulse noise measurement
In addition to basic TIMS measurements, the module also sup-ports 2-wire signaling for loop-start, DID (Direct Inward Dial), andGround Start. In addition DID + GS has PBX/CO with DP, DTMF,
MF dialing, and talk/listen capabilities.
For more application details, see Section 3of this Users Man-ual.
This module can be used with the full family of MTT and xDSL
test sets, however there may be minor screen differences betweenthe color and b & w models. This Users Manual uses the color
screens for illustrative purposes.
Note: The standard Sunrise Telecom AC adaptor may generatelow frequency noise which affects the frequency testing results.For this reason we recommend that during VF TIMS measure-
ment the battery or the Sunrise Telecom AC adapter, SS138Ebe used.
1.1 LEDsThe module does not use any LEDs for reporting on circuit condi-tions. It does however indicate its use by the MODULE LED.
1.2 Module Connector Panel

The module has the following ports:
HANDSET
Connect a standard handset using an RJ-9 connector. It is used
for talk/listen functions.
2W/4W
The 2W/4W port is a 6-pin RJ-11 connector. The center two pins (3& 4) are used in 2-wire mode. In a 4-wire mode running in normal
operation, the center pins (3 & 4) are used for transmitting andpins 2 & 5 are used for receiving. Pin 6 is ground.

NOISE: Measure the background noise on a cable pair. To
perform this measurement, there must be a quiet terminationor open at the end of the cable pair.
SNR: Signal-to-Noise Ratio is a ratio of the quality of the signalwith noise compared to the noise. This measurement must beperformed with a test tone, typically 1004 Hz.
PI: Power Inuence: Noise to ground.
NOISE FILTER
Options: C-MESG (F1), 3.4K (F2), D (F3)
Determine the type of filter used for the measurement.
C-MESG: C-Message weighs frequencies between 600 Hzand 3 kHz most heavily. It, therefore, measures noise in the
frequency spectrum most noticeable to the human ear. Thismeasurement is called metallic noise.
3.4K: This weighs frequencies above 3.4 kHz most heavily.
D: Also known as the CCITT0.41 Channel Bank Filter, weightsnoise or impulse noise as it relates to VF data or fax trans-
mission. The 3 dB bandwidth extends from 300 Hz to 3,400Hz approximating the transmission spectrum of a 28.8/V.34
modem. This filter is composed of a 300 Hz high pass filtercascaded with a 3.4 kHz low-pass lter. Both the analog anddigital realizations are shown in the following gure:

NOTCH FILTERThis line indicates if the filter is enabled or disabled. Its state is
determined by the MEASURE TYPE choice.
When ready, press ENTER. The following is reported:
RX FREQUENCY: Measured frequency in Hz. Only in NOISEand SNR measurements.
RX LEVEL: Measured in terms of dBm. A dBm unit measures thedecibels relative to 1 mW of power (across the selected imped-
ance). Only in NOISE and SNR measurements.
NOISE: Measured in terms of dBrn (decibels relative to noise). 0dBrn=-90 dBm. Only in NOISE and SNR measurements.
SNR: Signal-to-Noise Ratio is measured in terms of pure decibels(dB). Only in SNR measurements.
POWER INFLUENCE: Measured only in PI measurements. This is
a noise measurement taken with respect to ground to determinenoise from sources such as power lines.

2.5.2 Impulse Noise
This feature detects impulse noise spikes on the signal andkeeps a running count of the number of impulse events over time.
Impulse noise is dened as a random pulse whose amplitude issignificantly higher than that of background noise. IEEE defines
impulse noise as any burst of noise that produces a voltage ex-ceeding the rms value of the background or quantizing noise by
more than 12 dB [IEEE 743-1995].

pass lter cascaded with a 3.4 kHz low-pass lter. Both theanalog and digital realizations are shown in Figure 15.
DEAD TIMERange: 10 ms to 255 ms
This is the measurement delay after the test set detects the initial
impulse. Dead Time begins as soon as the test set detects theinitial impulse. It resumes measuring events after the dead timehas elapsed. This prevents the test set from measuring the same
impulse noise spike multiple times.

THRESHOLD (LOW)Range: 30 dBrn to 90 dBrn
Dene the lower threshold value for an impulse noise event. When
the test set detects noise above this threshold, the test set recordsit as an impulse noise event.
THRESHOLD SPREADRange: 2 to 6 dB
Set the difference between the Low, Middle, and High event
counts. In the top left screen in Figure 16, THRESHOLD (LOW)is set for 30 dBrn; this is the low count. The spread value is setfor 5. Therefore, the low count refers to any noise between 30 and
35; the middle count refers to any noise between 35 and 40. Highrefers to anything above 40 dBrn.
TEST TIME
CONT (Continuous) is the only option.NOTCH FILTEROptions: ON (F1), OFF (F2)
Choose whether to use this lter during the measurement.
When ready, press ENTER to start and refer to the right screenshown in Figure 16.
ET: Elapsed Time since ENTER was pressed.
RT: Remaining Time displays CONT, since this is the only option
for the TEST TIME setting.
The noise for HIGH, MID, and LOW is reported in dBrn. The fol-lowing counters provide the impulse noise results:
HIGH: Number of impulse noise spikes detected whose level falls
within the high value (above HIGH).
MID: Number of impulse noise spikes detected whose level fallswithin the middle value (in between MID and HIGH).
LOW: Number of impulse noise spikes detected whose level fallswithin the low value (in between LOW and MID).
The following F-keys are available:
CLEAR (F1): Resets all counters to zero. The test continues
running.
STORE(F4): Press to save the results. See Section 2.9.
When finished, press ESC.
