Use the following information to connect a Tieline codec to a Musicam CDQ Prima codec.

 

Programming the CDQ Prima for a Mono Connection

Select a mono profile in the Prima codec for the connection:

 

1.Press the “SDIAL” button on the front panel of the codec.

2.When “ID NUM” is displayed press “8” and then press "Enter" using the down arrow.

3.“MPEG2/64K:QS” will be displayed briefly followed by “WORKING”.

4.“OK” will be displayed momentarily and then the LCD screen will return to the default screen and be programmed for:

•A Mono connection.

•64Kbps Bit-Rate.

•48K Sample Rate.

•MPEG Layer 2 algorithm.

8.Use the "Enter" button and select the switch type for the country you are in. Check with your Telco for the correct setting if you are unsure. Note: During Tieline tests we used the internal "NI1" setting for the USA.

9.Use the "Enter" button and keypad to enter the "SPID 1" and "SPID 2" numbers if required.

10.Use the "Enter" button and keypad to enter the "ID 1" and "ID 2" (Directory/MSN) numbers if required.

11.The codec should now be configured.

3.“Zephyr/128K:QS” will be displayed briefly followed by “WORKING”.

4.“OK” will be displayed momentarily and then the LCD screen will return to the screen displayed prior to programming. The codec is now programmed for:

• A Joint Stereo connection.

•128Kbps Bit-Rate.

•48K Sample Rate.

•2 ISDN B Channels

•Decoder Independent – Yes

5.Press the right arrow on the "Enter" button and navigate to "Interface". Push the down arrow on the "Enter" button to select this menu.

6.Use the "Enter" button and navigate to the type of interface you are using. Note: During Tieline tests we used an "Internal TA".

10.Use the "Enter" button and keypad to enter the "ID 1" and "ID 2" (Directory/MSN) numbers if required.

11.The codec should now be configured.

Configuring the Tieline Codec to Connect to the CDQ Prima

1.Press the HOME home button button to return to the Home screen and select Connect > ISDN.

2.Navigate to Setup and press the Ok button button.

3.Select Session Type [Sessionless] > Select Dial Route [None] > Number of B Channels [Choose 1B (mono) or 2B (stereo)] > Algorithm [Choose MP2 Mono or MP2 J-Stereo (Note: select 48kHz sample rate for MP2 algorithms)].

4. Navigate to a Destination (e.g. Dest 1 or Dest 2) and press the Ok button button to select each one in turn. Enter the number for each B channel you want to dial and press the Ok button button, then select which B channel will dial using that number and press the Ok button button.

5.Navigate down to Auto Reconnect and press the Ok button button to toggle between Enabled and Disabled. Note: This is normally enabled on the dialing codec only.

9.Configure the following settings:

•Accept > Voice and Data

•Network > Check with your Telco (EU-ETSI in Australia; Europe & most countries outside North America; [US Nat] is the most common in the US, but check with your Telco).

•Line Type > Check with your Telco and select either Point-to-Multi (point-to-multipoint) or Point-to--Point (point-to-point).

•DN/MSN > Enter the "SPID" and "DN" numbers if required in your region, e.g. a SPID is normally required in the US.

10. Navigate up to Apply Settings and press the Ok button button.

 

Dialing from the Tieline Codec

Program Dialing

1.If you have saved the ISDN program as previously instructed, press the HOME home button button to return to the Home screen and select Connect > Programs.

2.Select the saved program you want to load and press the Ok button button.

3.Select Load and press the Ok button button to load the program.

4.Press the CONNECT connect button button to dial the ISDN program connections.

2.Press the Ok button button to dial using the settings previously entered.

 

After dialing successfully “FRAMED” should illuminate on the CDQ Prima screen. Tieline codecs also support 32kHz sampling.

 

information2

Important Note: Configure ISDN Answer Config settings in the codec before attempting to dial from the Equinox to the Tieline codec. Select the following settings in the Tieline codec in one of the Configs (see ISDN Answering Configuration for more detail):

•May bond.

•Sessionless.

•Algorithm: MP2 Mono, MP2 J-Stereo.

•Sample Rate: 48kHz

Making a Mono Call from the CDQ Prima Codec

1.Press the "Dial" button on the front panel of the codec.

2.Navigate right using the "Enter" button and select "1".

3.Enter the number to dial using the numeric keypad.

4.Press the "Enter" button (bottom arrow) and the screen will briefly display "Working", then "Connect" and then the green "Framed" light should illuminate on the front panel.

 

Making a Stereo Call from the CDQ Prima Codec

1.Press the "Dial" button on the front panel of the codec.

2.Use the "Enter" button and select "Both".

3.Enter the first number to dial using the numeric keypad.

4.Press the "Enter" button (bottom arrow) and the screen will briefly display "Dialling line 1" and then "Connect".

5.Enter the second number to dial using the numeric keypad and press the "Enter" button (bottom arrow).

6.The screen will briefly display "Dialling line 2", then "Connect" and then the green "Framed" light should illuminate on the front panel.

 

 

information2

Important Note:

When connecting in stereo, the Prima expects both B channel dials to occur within 5 seconds. This can be performed by the Tieline codec.

 

It has also been noted that the CDQ Prima codec will not connect if no audio is present when dialing. It may connect Prima > Tieline, but not Tieline > Prima. If audio is present, the codec should connect and stay connected even if audio is removed subsequently. The J-Stereo light on the Prima may also flash when in this mode.

 

Ideally, have audio connected when dialing and the codec will frame immediately after the first dial and then dial the second B channel quickly afterwards.
