Sample Monitor Full T1 Test

Use this test mode to monitor live data on the T1 line without affecting service. The simplest hookup for monitoring does not require the test set Tx outputs to be connected. In some cases, you may connect the Tx outputs to the T1 circuit. For those cases, the Tx primary and secondary transmitted signals are regenerated from the received signal on the corresponding line.
 In this example, you use the monitor test mode to test performance without disrupting service on a T1 circuit. During this test, the source of the signal from far end can be either live data or pattern data from a second test set. This mode is very similar to End-to-End Hard Loop mode, with the exception that the signal present on the Primary Tx jack is a buffered replica of the signal present on the Primary Rx jack. When monitor jacks are not available, this feature allows the technician to break into a live T1 and pass that signal through the test set, thereby keeping the circuit in-service. This is useful for monitoring long-term statistics of a T1 circuit.
To Preform a Monitor Full T1 BERT Test

Step
 		Notes
1
 		Connect the BSTS to the DSX panel
 		Refer to the Measurement Guide
2
 		[Mode]
3
 		[Backhaul]
4
 		[T1 Analyzer]
5
 		[Get Started/ Test Mode]
6
 		Setup monitoring.
  1. [Monitor]
  2. [Monitor Full T1]
Choose this to monitor performance of a full T1 Circuit.
7
 		Setup auto configuration.
  1. [Auto Config]
  2. [Primary Auto Config]
Causes the test set to analyze the incoming T1 signal and align the setup choices to that signal.
8
 		[Back]
 		Shifts focus back to the main mode selection buttons.
9
 		[Setup]
 		Select this to display a list of setup choices that pertain to this test mode.
10
 		Setup the Rx Input.
  1. [Setup]
  2. [Rx Input]
  3. [Terminate]
This assumes the test set is connected into a jack that interrupts the T1 circuit.
Note: If you are connected to a monitor port, select [Monitor] instead of [Terminate].
11
 		Setup line code.
  1. [Line Code]
  2. [B8ZS]
This assumes the circuit is designed for B8ZS.
12
 		Setup framing.
  1. [Framing]
  2. [ESF]
This assumes that the circuit has been designed for ESF.
13
 		Select a pattern.
  1. [Pattern]
  2. Use the up and down buttons to select.
  3. QRSS
  4. [Select]
Set to the pattern sent by the far end.
14
 		Setup Tx clock.
  1. [Tx Clock]
  2. [Internal]
This selection is not applicable in Monitor mode because the Primary Tx signal is a buffered replica of the signal applied to the Primary Rx jack and is not affected by this setting. This is the default selection after test set preset.
15
 		Setup the Tx LBO.
  1. [Tx LBO]
  2. [0 dB]
This is a typical level found at the customer demarcation point.
16
 		Setup the slip reference.
  1. [Slip Ref]
  2. [None]
Disables the frame slip measurement.
17
 		Setup the second Tx.
  1. [Second Tx]
  2. [AIS]
Use the default condition.
18
 		[Display]
 		Enables the [Display] options on the buttons on the right.
19
 		Setup the display.
  1. [Display]
  2. [Status]
  3. [Pri]
Enables the [Display] options on the buttons on the right. Activates only the Primary Status pane. The inactive channel should be deactivated to stop the display of invalid measurements.
20
 		Setup the alarms.
  1. [Alarms]
  2. [Pri]
This selection causes the Alarm pane to toggle between Primary and Secondary. Use this selection to observe the Primary Results in the Alarm Panel.
21
 		Setup the results display.
  1. [Results]
  2. Use the up and down arrows to select.
  3. Make a selection.
  4. [Select]
Make a selection based on the need of the application.
22
 		[Control]
 		The selection enables several soft keys on the right that control choices specific to each test mode.
23
 		Select a pattern.
  1. [Pattern]
  2. Use the up and down buttons to select.
  3. QRSS
  4. [Select]
Select a pattern.
