Sample Monitor Full E1 Test

This example shows how to monitor an E1 circuit without disrupting service. During this test the source of signal from the 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 E1 and pass that signal through the test set, thereby keeping the circuit in-service. This is useful for monitoring long-term statistics of an E1 circuit.
To Preform a Sample Monitoring Procedure

Step
 		Notes
1
 		[Mode]
2
 		[Backhaul]
3
 		[E1 Analyzer]
4
 		[Get Started/ Test Mode]
5
 		Setup monitoring.
  1. [Monitor]
  2. [Monitor Full E1]
Use this test mode to monitor live data on the E1 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 E1 circuit. For those cases, the Tx primary and secondary transmitted signals are regenerated from the received signal on the corresponding line.
 Choose [Monitor Full E1] to monitor performance of a full E1 Circuit.
6
 		Setup auto configuration.
  1. [Auto Config]
  2. [Start Primary Auto Config]
Causes the test set to analyze the incoming E1 signal and to align the setup choices to that signal.
7
 		[Back]
 		Shifts focus back to the main mode selection buttons.
8
 		Setup the Rx Input.
  1. [Setup]
  2. [Rx Input]
  3. [Terminate]
This assumes the test set is connected into a jack that interrupts the E1 circuit.
Note: If you are connected to a monitor port, select [Monitor] instead of [Terminate].
9
 		Setup line code.
  1. [Line Code]
  2. [HDB3]
This assumes the circuit is designed for HDB3.
10
 		Setup framing.
  1. [Framing]
  2. [PCM31 + CRC4]
This assumes that the circuit has been designed for PCM31 + CRC4.
11
 		Setup pattern.
  1. [Pattern]
  2. [QRSS]
Set to the pattern sent by the far end.
12
 		Setup Tx Pattern.
  1. [Tx Pattern]
  2. [Normal]

13
 		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.
 Internal is the default selection after test set Preset.
14
 		[More 1 of 2]
 		Displays further options. Choose [More 2 of 2] to return to the previous list of options.
15
 		Setup the slip reference.
  1. [Slip Ref]
  2. [None]
Disables the frame slip measurement.
16
 		Setup the second Tx.
  1. [Second Tx]
  2. [AIS]
Use the default condition.
17
 		[Display/Sound]
 		Enables the [Display] options on the buttons on the right.
18
 		Setup the status display.
  1. [Status]
  2. [Pri]
Activates only the Primary Status pane. The inactive channel should be deactivated to cease the display of invalid measurements.
19
 		Setup alarms.
  1. [Alarms]
  2. [Pri]
This selection causes the Alarm pane to toggle between Primary and Secondary.
 Use the Pri selection to observe the Primary Results in the Alarm Panel.
20
 		Setup the results display.
  1. [Results]
  2. Use the up and down buttons to move to the desired choice.
  3. [Select]
Enables a list of results information that can be displayed in the Results pane. Make a selection based on the need of the application.
