Installation Summary

1. Visit windowsupdate.microsoft.com to ensure you have the

latest USB drivers available from Microsoft.

2. Connect inputs 1-16 via the Amphenol connector. Each line uses a single twisted pair of wires. Confirm connections and check wiring.

3. Power-up the logger. Use the buttons on the right to select each line. Make a test call on each line. Use the speaker to monitor while adjusting the recording level using the buttons on the left. The slider controls speaker volume only. Adjust recording levels using the keypad arrows. Confirm sound quality. Peak levels should measure below +3dBm. Excessively high input levels cause distortion.

4. Power up the PC. Insert the CD to install the logging application as described below. Don’t connect the USB cable quite yet.

5. After the recording application is loaded, attach the USB cable. Connect directly to a primary 480Mbps USB 2.0 or 3.0 port, not to a hub. Once attached, the USB configuration on this PC should not be changed. Windows will load drivers and the application will need to be restarted if the logger is moved to a different USB port. Note: A 480Mbps+ port is required. Long cables and USB extenders are not recommended. 11Mpbs USB

1.1/2.0 ports won’t work.

6. Select a target SSD or disk array to store recordings. Confirm available disk space. Map a network drive on the workstations used for playback. Use Windows permissions to limit access to authorized users.

7. Determine if you’re connected to “wet loops” or dry lines. See below for more information. Select a separate recording trigger mode, either VOX or LOOPSTART for each type of line. In VOX mode, set a trigger level for each line.

8. Install accessory software. Load Call Investigator or Evidence Builder call cataloging utilities as required on playback workstations. Install Real Time Player for remote monitoring. Install Call Detail Recorder to record SMDR, ANI, or ALI from RS-232 sources.

Power and USB Connections

Verify the input voltage is 90-240VAC. Plug the IEC power cord in to power up the logger. Use the internal monitoring speaker as an aid to identifying and connecting inputs, but don’t connect the USB cable until – after- software installation is completed.

Front Panel Operation

Adjusting recording levels using the front panel is very important. Recording quality depends on proper level settings. Excessive gain causes “clipping” distortion. Switching Auto Level on does not preclude level adjustment because the programmable gain amplifier and level booster are connected before the ALC. The Level Boost and manual level settings work in unison. If levels are set too high, distortion will occur, even with Auto Level enabled.

Level Boost should be enabled only for handsets and microphones with very low input levels (ie. below -20dBm). To reset all level settings to defaults, press and hold the up/ down channel buttons simultaneously.

You can record from…

1. an outside analog line.

2. an analog port on a PBX (such as a voicemail port).

3. an analog extension or speakerphone.

4. any handset, headset, or analog accessory jack

5. microphones or other analog audio sources

To record VoIP phones, tap an outside analog line, handset, or analog accessory jack on the back of the phone. ISDN and Ethernet are not analog audio signals. To record proprietary formats like Nortel ISDN extensions, you can use D/A converter designed specifically for your PBX. DLI carries T1/PRI loggers for direct digital recording of outside lines. PRI loggers are often used in VoIP systems with PRI connections.

DLI 16 CHANNEL LOGGER

Wet Loops vs. Dry Lines

A voltmeter is helpful in determining if your inputs are “wet loops” or dry lines. Wet loops typically carry -48V DC when measured off-hook. Wet loops are used to connect to your telecom provider, to your PBX, or to analog phone extensions. Dry lines such as headsets, radios, microphones and speakers carry audio, but no DC signaling voltage.

After you’ve determined a line type (either wet-loop or dry line), select a recording trigger: either Loop Start or VOX. Outside wet loops and inside analog extensions normally use Loop Start signaling. All dry lines use VOX signaling to trigger recording.

VOX Recording for Dry Lines

To bridge a dry line using Voice Operated Switch (VOX):

 Note: VOX mode is used for dry lines (lines that do not carry

signaling voltage). Examples are handset connections, headsets, radios, microphones and speakers.

 Use a punch-down block, handset Y connector, breakout box, or

RJ-11 octopus cable to connect each line (two twisted wires) to the logger. Each of the logger inputs connects in “bridge” fashion across the existing wiring.

 Verify that the line audio level is within telecom specifications.

Peak level should not exceed +3dBm. Gain controls should be set so that recording levels do not exceed 0dBm. Use Level Boost only if the input level is below -20dBm. If the VU meter peaks, the line level is too high. Reduce it using the manual gain controls, turn off Level Boost, and/or switch Auto Level on.

 Use Level Boost for handsets, microphones, and low-level

signals only.

 Rename the line label by clicking on the line name. Type the

new name and press Enter. For example, a handset tap or analog extension connected to LINE 01 might be renamed “Support Desk.”

 Set the line configuration mode to VOX by clicking on the line

mode.

there are hundreds of D/A converters available. Be sure to purchase one that matches your station sets. DLI carries some Algo products.

Recording Consent and Warning Tones

Many states require the consent of two parties prior to recording. In locations where there is “no reasonable expectation of privacy”, such as 911 PSAPs and prisons, consent is not normally required. Most PBXs can be easily set up to provide a warning such as, “Your call may be monitored and recorded for quality assurance...” DLI manufactures optional record tone generators which inject a periodic warning tone on outside analog POTS lines or extensions. DLI can’t offer legal advice or information on admissibility of recordings, so check with your attorney to confirm compliance with state and local laws prior to recording.

Recording File Format

Audio files are recorded using the industry standard -law (pronounced “mew-law”) format. Files are grouped in directories, with each channel and date corresponding to a single directory. The line name corresponds to the recording directory name, and can be changed. File names are sorted by start time in ascending order. All time values are standard 24-hour military time. A separate subdirectory is created for each day. The following example shows how the time and date stamps are directly coded into the file names:

Channel Day File Name

Directory Subdirectory

LINE01 20130403 212450da.au

Path: Recording_Directory/LINE01/20130403/212450da.au

In this example, a call arriving on line one, on April 3rd, 2013 was recorded, starting at 21 hours, 24 minutes, and 50 seconds (9:24:50PM). -law files are recorded at a 64kbps=8KBps data rate, so there is no audio quality loss due to compression. The length of each file is directly proportional to the length of the call. Windows Media Player displays the exact elapsed recording time.

DLI 16 CHANNEL LOGGER

 Set the VOX trigger threshold to a level slightly above the noise

floor (background noise level) of each line.

Loop Start Recording for Wet Loops

To bridge a wet loop line using Loop Start (LPS):

 Note: Loop Start mode is used only for “wet loop” analog lines,

such as analog extensions and outside POTS lines. Measure the idle DC voltage on the line to confirm that 48VDC is present on a wet loop.

 Verify that audio input levels are within standard telecom

specifications. Peak level should not exceed +3dBm. Gain controls should be set so that recording levels do not exceed 0dBm. Disable Level Boost for wet loops.

 Using a punch-down block, breakout box, or octopus cable to

connect each outside line to the logger. Each line is a two wire pair. Each of the logger inputs connects in “bridge” fashion across the existing wiring.

 Verify audio quality using the speaker on the logger. If the audio

sounds distorted, the recording level may be set too high. Turn it down or select Auto Level.

 Rename the line label by clicking on the line name. Type the

new name and press Enter. For example, an outside wet line connected to “LINE 01” might be renamed “(408) 330-5599”.

 Set the line mode to LPS by clicking on the line mode.

Connecting Radios

Manufacturers use a wide variety of radio connectors, so you’ll first need to locate a mating connector. After that, it’s a simple two-wire connection from the receiver to the logger. You can directly bridge across the speaker, headset, or ear bud at levels up to +3dBm. Levels higher than that will cause clipping distortion. If you are bridging a loudspeaker, turn the level down or add a series resistor to attenuate the signal. Connect to a pair of input pins on the logger. A punch down block is usually the most convenient way to mix radio and phone lines.

Page 10

DLI 16 CHANNEL LOGGER

If you’re connecting a radio transceiver, and you’d like to record both the transmitted and received audio in the same recording file, you’ll need a 4-wire to 2-wire converter. DLI builds custom military intercom and radio loggers as well as specialized recorders for military and E-911/P25 applications.

Setting the Record Level

Recording levels can be controlled from the front panel using a membrane keypad: Use the up/down arrows to select a channel, then use the arrows on the left side to the logger to adjust the recording level. The slider-bar and speaker help verify audio quality.

It’s important to set the recording level correctly. Low levels are hard to hear. High levels cause distortion in the recordings, making it difficult or impossible to decode Caller-ID or DTMF. This distortion is known as “clipping”. Set each line so the VU meter never quite reaches the red peak bars during normal recording. If you’re unsure, start by setting the gain to 0dBm, turn Level Boost off and select Auto Level.

To reset all level settings to defaults, press and hold both the up and down channel selection buttons simultaneously.

Setting VOX Trigger Level and Timeout

To use VOX mode, first adjust the recording level to avoid clipping as described above. Once the recording level is set correctly, hang up the line and adjust the VOX trigger level about 6dB above the noise floor. The VOX trigger level is the threshold at which recording will begin. In other words, when the logger “hears” a sound louder than the VOX trigger level, it will start to record. On a line with background noise, you’ll need a higher trigger level.

Recording will continue until silence is detected for a period of time. This period of time is called the VOX timeout. Start with a timeout of 30 seconds for phone calls, and 10 seconds for radios. Listen to the

DLI 16 CHANNEL LOGGER

D/A Converters

D/A stands for Digital-to-Analog. D/A converters or “DACs” install between digital lines (usually station sets) and an audio logger. D/A converters work by converting the signal stream from a digital station set into the standard analog format used in an audio logger. They are available in single and multi-channel versions.

Since there is no "standard" for proprietary digital station set interconnects and line formats, D/A converters are best purchased from the manufacturer of the PBX. PBX manufacturers often call these “recording adapters”.

Multi-channel D/A converters are available as stand-alone units or PCI cards. These cards are sold by Dialogic (now Intel), Algo, and others. Every proprietary phone switch uses a unique non-standard format, so

Balanced vs. Unbalanced Lines

Balanced lines are lines use to cancel noise. In balanced phone lines, two wires are twisted together so that each wire picks up the same amount of noise. At the receiving end, the noise is subtracted, and the resulting output is the sent audio, minus the noise. A balanced line becomes "unbalanced" when unintentional leakage to ground occurs. Unbalancing a phone line causes noise. This can be a result of

poor insulation somewhere along the line, or a bad connection. The problem is often worse in the winter, when outside lines are wet and leakage to ground occurs along the line.

Audio is transmitted down relatively short unbalanced lines using coaxial shielding. This shielding prevents electromagnetic noise from affecting a single wire. The inputs to all DLI loggers are balanced lines. These inputs may be connected directly to unbalanced (ie. Coaxial) lines, and the ground may be connected to either side of the logger input. In other words, either of the logger input lines (known as Ring and Tip) can be grounded.

DLI 16 CHANNEL LOGGER

recordings, and then adjust the timeout value to your liking. An excessively long timeout setting will combine multiple calls into a single file. An excessively short setting will cause calls to break apart into multiple recording files during periods of silence.

The VOX trigger level is adjusted by sliding the white arrowhead above the VU meter bar graph.

VOX trigger level settings do not apply to lines operating in the LOOPSTART, Continuous, or Complex modes.

When operating the logger in VOX mode, two settings are vital: VOX TIMEOUT and VOX TRIGGER LEVEL. Set the VOX trigger level slightly above the noise floor (ambient noise) on the line when the phone is onhook. If you change the recording level using the keypad on the front of

the logger, you may need to readjust the VOX trigger level in the app.

Unused Lines

Logger inputs are sensitive. Unused lines may record noise coupled from adjacent wiring, or produce feedback or hum in the speaker when Level Boost is enabled. Set unused lines OFF in the application, turn the gain down on unused lines, or terminate the wiring. A ground lug is provided on the rear panel of the logger. You may wire this to a good ground connection to prevent noise from entering via the power cord.

Software Setup and Installation

Inserting the driver CD and allowing setup.exe permission will spawn an installer shell. Start by installing recording software on the machine that will be attached to the USB cable.

Click on the photo of the logger and click Install Selected… to begin installation. The USB cable should still be disconnected at this point.

If you haven’t updated Windows recently, we recommend a visit to windowsupdate.microsoft.com to obtain the latest USB host drivers before installing the logging software. If you’re running automatic updates, you should be OK. After updating, insert the logger installation CD into your CD-ROM drive. For a smooth installation, don’t connect the logger USB cable until you have completed installing the software drivers.

security and fire alarm systems that provide exchange to alarm reporting devices.

In an RJ-31x installation, the phone line is wired in series through the RJ31X; from there, tip and ring pass through the dialer. A normally closed relay opens if the alarm is activated, seizing the circuit for alarm use, while temporarily disconnecting lower priority equipment (such as a house phone) to prevent disruption of the dialing sequence.

The most common RJ-31x installation is an 8-position, non-keyed miniature jack with shorting bars across terminals 1-4 and 5-8. Inserting the modular plug lifts the contact wires away from the shorting bars, extending the tip and ring circuit to the series leads going into the alarm device. The audio logger connects to pins 4 and 5 of the jack in a "bridging" configuration. When the plug is removed from the jack, metal tabs inside the RJ-31X provide direct connection of tip and ring back to the other locations, bypassing the alarm device. This design lets the dialer control the line for exclusive use when in alarm mode. It also helps isolate defective or improperly wired equipment by disconnecting the RJ31x plug to route tip and ring directly to lower priority equipment. In some 911 installations, a dispatch console will be rerouted to a backup console by connecting the backup console to the "house phone" connections on pins 1 and 8. Always connect the logger to the OUTSIDE (Socket Side) of the FIRST jack socket, pins 4 & 5.

Some technicians may install a "shortcut" or de-populated four-terminal version of the dialer jack. In the shortcut dialer jack, the jumpered terminals (which supervise the presence of the plug) are missing. This "shortcut" jack can't detect the presence of the modular plug. It is best to install a fully populated RJ-31X jack, and properly connect all terminals. All RJ-31 X jacks should be installed in front of any other jacks in the system so that when an alarm occurs, automatic dialing will take priority and seize the line, leaving all other phones disconnected.

RJ-45, RJ-61 and T568 Jack Connection

Although it's not technically correct, the term "RJ-45" is now used to refer to any standard 8 pin jack in telephony or networking applications. Although originally designed for analog audio, RJ-45 jacks are now most commonly used in Ethernet applications. Eight pin jacks can carry four analog circuits. An Ethernet jack can’t be connected to an analog input. Listed below are the correct color codes for 8-pin telecom and Ethernet jacks.

Alarm and security companies use a special type of jack, called an RJ31x. It is an "exclusion type" dialer jack. It is typically a Leviton style 8 pin jack with an internal switch. Similar wiring may be done on KT-66 or W110 punch down blocks with bridging clips. Each 66 block handles 3 lines of RJ-31x wiring configuration, and all the pin order matches the order of the RJ-31x jack pins. The first jack connects to pins 1-8, the second to pins 9-16, and the third to pins 17-24. This type of wiring is commonly encountered in commercial alarm installations, fire alarms, elevators, and 911 dispatch consoles. RJ-31X jacks are required for

To connect an RJ-21X to an RJ-11 jack, you can use either a rack mount patch panel with 24 RJ-11 jacks, or a "harmonica" or "octopus". An Octopus cord has a single 50 pin AMP connector (RJ-21X type) on one end, and 24 RJ-11 type plugs on the other end. Another useful connector is an RJ-21 “Tap” or “Y” cable. These optional parts and cables are available directly from DLI and through telecom dealers.

RJ-12 Handset Jack and AUX jack Connection

A handset jack is a small 4 pin connector which carries the speaker and microphone signals between a telephone and handset. Many phones including most Cisco VoIP phones have an AUX connector which provides analog audio output to a headset or logger. This is a good place to bridge an audio logger, since both incoming calls and intercom conversations for a single extension may be recorded at this point. The default VOX and ALC settings will work fine with the typical handset level with the Gain Boost setting enabled. To record from a handset, “backhaul” the audio to the logger via either a “Y” connector, and AUX jack, or make the connection within the phone itself. This can be done with an unused pair on an existing cable. Smaller handset jacks won’t make a reliable connection in larger RJ-11 jacks. Y connectors for the smaller handset RJ-12 plugs, and cables with RJ-11 to RJ-12 jacks are available from DLI.

The connector itself is sometimes called an “AMP”, “CHAMP”, "blue ribbon", or "gray phone" connector. RJ-21 connectors are polarized (male and female) to prevent an installer from accidentally connecting an internal extension to outside lines (or vice versa). Although the keying is designed to prevent inverted installation, it is possible to force a plastic connector on in reverse.

Pins 1 (ring) and 26 (tip) are considered position 1. Pins 2 (ring) and 27 (tip) are position 2 on thru twenty five pairs. Typically, only 24 pairs are used (48 wires). Your 16 channel logger uses only the first 16 pairs (32 wires). The last pair on pins 25 and 50 (slate-violet and violet-slate color) should be left as a spare pair. The spare pair keeps you from having to run a whole new cable if a single pair fails elsewhere. DLI Loggers use this pair as an earth ground connection. The logger can be directly connected to most RJ-21x jacks via an Amphenol cable.

RJ-21 Color Code

RJ-21 cables follow the color code standard used in all telecom wiring: Line 1 is the blue & white pair, Line 2 is orange & white pair, etc. as shown.

The logger pinout complies with this telecom standard, but pins 17-24 and pins 42-49 (lines 17

to 24) are not connected.

The 25th pair provides an earth ground connection.

When mounted correctly, a KT-66 block will have line 1 on the uppermost pair, and line 25 on the bottom of the block.

Logger Input and RJ-21X Connection / Color Codes

Typical RJ-21 Audio Logger Mating Connector

An RJ-21 cable is a standardized phone cable uses 50 wires to transmit up to 25 channels of digital or analog data. It is called an RJ-21x when it is used as a "demarc" or attachment point for telcom equipment. The "demarc" attachment point is commonly referred to as a "Network Interface Device". An RJ-21X can be attached to a standard KT-66 or 110 type punchdown block, and is typically installed by the phone company. In many installations, the customer is responsible for all wiring

after the RJ-21X, and the phone company is responsible for all wiring before the RJ-21X. The circuits on an RJ-21X are provided on

numbered tip and ring positions on a miniature 50 pin connector of the "AMP" type. These are very common connectors used on PBX, KSU, PBC, and distribution frames.

Storage path is the final selection. We recommend you use a separate hard disk or disk array for file storage. Keeping your audio files on a separate drive will increase performance and reliability. If the disk selected doesn’t have adequate space, a warning message appears.

At this point, you’re ready to start the installation… If you receive subsequent security warnings from Windows, allow the system to install drivers. After the installation is completed, it’s finally time connect the USB cable to the logger. Power-up and attach the logger. Make sure the factory USB cable is used. Connect directly to the host computer, not through a USB hub.

If the recording application couldn’t detect the logger, this warning appears. Check power and USB cabling. Power-up and attach the logger. Make sure the factory USB cable is attached.

Once the application and drivers are properly loaded and the logger is recognized, this screen appears:

Note that the level meters are low and uncolored. The application is not recording at this point. When recording is not triggered, the VU meter bars appear “grayed out”. While recording, the bars indicate the VU level recorded in the file.

How do I connect the logger to a PBX?

There are three basic ways to link your logger to the outside world:

Record from incoming lines.

This method records from the outside party’s perspective. The recording will follow the caller as he is transferred through the PBX. Incoming lines are commonly recorded for quality assurance. For agent analysis or 911 call center recording, a console output or handset tap is usually a better connection point. When recording from incoming lines, the level of the calling and answering voices may differ. For a more balanced recording level, use a handset connection or console output, or enable Auto Level.

Tap the handsets, AUX jack, dispatch console, or analog station sets.

This method allows you to hear the recording from the agent’s perspective. If you are recording in an E-911 dispatch environment, this connection will listen-in from the dispatcher’s perspective. Recordings made from these connections will typically include the phone conversation, radio dispatch, etc. You will record everything the agent or dispatcher hears. Most consoles have a dedicated recording output. Handset taps may be connected to any phone, including VoIP extensions. When recording from a handset, Caller-ID won’t be included in the audio stream, but it may be logged using SMDR.

Connect to a PBX port.

This is a common method of connecting a logger in large installations (100+ channels). One advantage of this connection scheme is that the PBX can be used to switch the recorder to a large number of lines. Another is that the logger can be switched to any recorder outside trunk or inside extension. Think of this method as “conferencing in” the logger with either an outside caller or an inside extension. This method requires familiarity with PBX programming.

Remote Level Adjustment

For remote maintenance, a level adjustment utility is provided. Select either ALC (Automatic Level Control) which is equivalent to pressing Auto Level on the front panel, or use the slider for a fixed gain level. Press Apply to commit changes. Level settings are stored in the logger itself.

Recording SMDR, ANI, and ALI Streams

ANI, ALI, or SMDR data streams may be logged using our call detail recorder utility. This utility logs up to 8 RS-232 serial ports simultaneously. Download CDR from: digital-loggers.com/CDR.exe

When lines are active (recording), the audio level is displayed in color on a bar graph like this:

This is the main user-interface screen which includes a graphical VU meter and several other elements. There are several mouse shortcuts on this screen. The most important are:

Clicking on Line Number

Clicking the line number spawns a window displaying the recording files for that line. Files are organized in daily directories. Click on the file to play it. This is a simple shortcut to play files.

Left Clicking on Line Name

Clicking on the line name allows you to change it. The recording directory name will also change. Press Enter to commit the change.

Right-Clicking on Line Mode

Clicking on line mode, ie. VOX allows you to select one of the five recording modes described below:

Sliding (dragging) the VOX Trigger Level

The VOX trigger level is the minumim sound level that will start recording in the Voice Operated Switch (VOX) recording mode. To adjust this level in real-time, slide the arrowhead on the VU meter located to the right of the line name. The VU meter is colored gray when recording is stopped. When recording is started, the VU meter is colorized. To properly adjust this level, hang up all phones and turn off all input sources. Check the VU meter level. The level shown with phones “on hook” is called the noise floor. Start with the VU trigger level about 10dBm above the noise floor. Make test recordings. Adjust the level higher or lower as necessary. The period of silence after which recording is terminated is called the VOX timeout. This time value may be adjusted on the line settings page.

Network Real Time Player

To play a call recording, simply click on the recording file. This plays a recording, but not in real time.

Remote users with access privileges may prefer to monitor calls in real time via LAN or WAN connections using this application.

A Real Time Player application is provided on the distribution CD. It’s downloadable from: digital-loggers.com/RTP.exe

To remotely monitor calls, load the Real Time Player application on a workstation. Click Options. Use the browse button to select a source directory with archived or incoming calls. Live calls are highlighted. Select a call and press Play, or press Live to continuously monitor calls as they come in. Windows security may be used to selectively control access to specific lines.

Evidence Builder Playback App

Evidence Builder Software is a powerful program used to locate and analyze recordings. Load this on a workstation and point it at the recording directories to analyze incoming calls, create call lists, sort calls, and search by DTMF or Caller-ID. It also has unique abilities like spreadsheet export, and the ability to add spoken audio time and date stamps to recording files. You can easily concatenate multiple files and launch audio editing programs from Evidence Builder.

To catalog files on a remote server, first create a path to the shared recording directory. Be sure to use proper security. Map this to a drive letter on your workstation.

Next, choose the Catalog Files From Hard Drive button and select the top recording directory. The screen display can be customized by in the Preferences menu. Click Help link for more detailed usage.

Logger Configuration Page

Clicking the Logger Configuration icon brings you to this page:

To adjust the settings for each line, first click on the line name. The settings for that line appear in the right window pane. The default settings are good for most installations, but the recording trigger mode often needs to be adjusted. Five modes are available:

Disable

DLI 16 CHANNEL LOGGER

Prevents recording for this line. Select this for unused lines.

VOX

Starts and stops recordings automatically based on the sound level on that line. Use this setting for all dry lines, such as radios and handsets. In VOX mode, you will need to adjust the VOX Trigger Level to start recording at a trigger level specified in dBm.

Continuous

Use this always-recording setting to record a line 24x7.

LoopStart

Select loop start for wet lines. This mode monitors the DC voltage on the line to determine if a phone is off-hook.

Complex

Complex mode is used for wet lines and will “pre-record” when sound is detected prior to a phone going “off hook”. It’s useful for catching callerID on wet lines. Caller ID is normally transmitted between the first and second ring.

Pre-Record Time

Selecting a pre-recording time will include audio before the VOX or Loop Start trigger was detected. This is useful for recording Caller ID (CID).

Trim Silence

By definition, a VOX controlled recorder will not stop recording until a period of silence occurs. To trim this silence data from the end of a recording file, select a trim level in dBm using the Trim Silence setting.

DTMF Settings

DTMF settings do not normally need to be changed if input levels are set correctly. If you must increase recording gain to the point at which clipping distortion occurs, these settings will need to be reduced.

Most other settings are self-explanatory. Be sure to click the “SAVE” button to commit changes. Feel free to contact us at (408) 330-5599 with questions and suggestions.

Using the Logging Application

Click on the DLI Audio Logger icon to start the application. The main screen appears:

The recording mode for each line, ie VOX, LOOPSTART (abbreviated LPS) or OFF is displayed to the left of the line name. The recording level for each line appears decimal and color bar graph format when that line is recording.

Adjust the gain controls so that the highest levels (ie. dialing) peak at around 0dBm. Setting the level too high will cause distortion and prevent touch tones and Caller-ID from being properly decoded.

Click on the line name to explore the recordings for that line.

DLI 16 CHANNEL LOGGER

Line Name

Choose “PSAP Desk 1” or a similar useful extension name if you have a channel assigned to a single speech path in your PBX. If you have a particular phone number assigned to that timeslot, it may be useful to include the number in the line name, such as “DLI Main Hunt Group (408) 330-5599”. If you are recording from an outside trunk, a separate program will allow you to search by Caller-ID or DTMF signaling after recording. Since this Line Name will be used as a recording directory,

be careful not to include disallowed characters, such as “/” “,” or “\”.

Maximum Megabytes

The logger can automatically delete old calls to conserve the amount of disk space used by each channel. This setting controls the maximum amount of disk space used by each channel. When disk space is low and this threshold setting is reached, oldest calls are automatically deleted to free disk space. To turn this feature off, set this field to “0”. If you specify a maximum, the logger will check disk space periodically. If recording size exceeds your setting, the logger will automatically delete files starting with the oldest day. The logger will continue deleting calls until disk usage reaches the setting. It’s important to set this so that the total space used does not exceed the available disk space. You may want to run the logger for a few days, and then evaluate the usage on a line-by-line basis.

Enable Call Analysis

If Caller-ID (CID) and touch tone dialing (DTMF) tones are present in the recordings, the logger can analyze the audio to extract this information. Having the number dialed makes it easier to organize and find calls. CID is a paid subscription service in most areas. CID is not available on a handset connection, or if a phone is answered before the second ring. Enable analysis to decode these tones.

USB Serial Driver Installation

If you have successfully installed the recording application before connecting the logger, skip this section. If you connected the USB cable –before- installing the software, Windows will guide you through a USB serial driver installation process. We suggest you cancel this process, disconnect the logger and install the driver CD, but here is the procedure for manual installation:

If you have already started the process, you’ll need an internet connection to load the driver. Choose the Search option first.
