DS0 Termination

The DS0 Termination object describes a DS0 connection that runs over a DS1 line.

This object is pre-configured (configuration information is delivered with the NE), and you cannot create or delete it.

Each DS0 Termination object is a child of either a DS1 Over DS3 Port object or a Physical DS1 Port object.

Object-Specific Actions
The tone generation and detection actions are visible only if the grandparent Adaptor object is a PB4000, PB4500, or PB5000 Adaptor. These actions do not appear on a VP3500 Integrated Softswitch or MG3500 Media Gateway.
Start DS0 test tone generation If this DS0 is not in use, the DS0 starts to generate a test tone. To configure the test tone generated, see the Tone generation test fields. This action is disabled when the DS0 is already generating a test tone. The tone has a frequency of 1004 Hz.
Stop DS0 test tone generation This action stops the DS0 generating a test tone. This action is disabled when the DS0 is not generating a test tone.
Start DS0 test tone detection If this DS0 is not in use, the DS0 starts to listen for a test tone. To view the results of this test, see the Tone detection test fields. This action is disabled when the DS0 is already listening for a test tone.
Stop DS0 test tone detection This action stops the DS0 listening for a test tone. This action is disabled when the DS0 is not listening for a test tone.

Description
Timeslot Read only The timeslot on the TDM port that this termination uses.
In use by Read only Specifies which termination protocol, if any, is currently being used on this timeslot. Values:
  • ISUP
  • Line
  • MTP2
  • IVR
  • ATM
  • BITS
  • IAD Management
  • E and M
  • E and M wink start
  • RTP
  • LAPD
  • ISDN
  • Clear Channel
Tone generation test - status Read only This field is visible only if the grandparent Adaptor object is a PB4000, PB4500, or PB5000 Adaptor. This field does not appear on a VP3500 Integrated Softswitch or MG3500 Media Gateway. Specifies whether this DS0 is currently generating a test tone. Values:
  • Generating tone
  • No test in progress
  • Last tone generation failed
To change the test status, you must use the actions on this object: start DS0 test tone generation and stop DS0 test tone generation.
Tone generation test - test failure log correlator Read only This field is visible only if Tone generation test - status is visible and set to Last tone generation failed. Identifier of the informational log containing details of the event that caused the last tone generation test to fail.
Tone generation test - level Read only / Change This field is visible only if the grandparent Adaptor object is a PB4000, PB4500, or PB5000 Adaptor. This field does not appear on a VP3500 Integrated Softswitch or MG3500 Media Gateway.
  • When a tone generation test is in progress (Tone generation test - status is set to Generating tone), this field is read only and specifies the dBm level of the test in progress.
  • When a tone generation test is not in progress, this field can be changed to set the dBm level for your next test on this DS0.
Range: -16 to 0 dBM.
Tone detection test - status Read only This field is visible only if the grandparent Adaptor object is a PB4000, PB4500, or PB5000 Adaptor. This field does not appear on a VP3500 Integrated Softswitch or MG3500 Media Gateway. Specifies whether this DS0 is currently listening for a test tone. Values:
  • Tone detected
  • Waiting for tone
    A test is in progress, but no tone has yet been detected.
  • No test in progress
  • Last tone detection test failed
To change the test status, you must use the actions on this object: start DS0 test tone detection and stop DS0 test tone detection.
Tone detection test - test failure log correlator Read only This field is visible only if Tone detection test - status is visible and set to Last tone detection test failed. Identifier of the informational log containing details of the event that caused the last tone detection test to fail.
Tone detection test - level Read only This field is visible only if Tone detection test - status is set to Tone detected. Specifies the dBm level of the tone that has been detected during the current test, with an accuracy of +/- 0.5dBm. Range: -45dBm - 0dBm
Tone detection test - frequency Read only This field is visible only if Tone detection test - status is set to Tone detected. Specifies the frequency (in Hz) of the tone that has been detected during the current test, with an accuracy of +/- 3Hz.
