How to Perform Circuit Looping

Allows you to perform circuit looping on private circuits (Kilostream and Megastream) and view the status of applied loops after completing the Security Check.

Note: If you perform an Alarm Check on a private circuit via the:
§		Private Circuit Alarm Check on the Diagnostic menu,
		or the
§		Create Fault process,
and proceed to peform Circuit Looping on the same private circuit within ten minutes of the orginal Alarm Check, the Alarm Check for the circuit will not be automatically repeated as part of the Routing Diagram process.

The Security Check test ensures that only authorised personnel can perform circuit looping on external customer circuits.

How Perform the Security Check

The Security Check is applied when you first select Circuit Looping from the Diagnostic Menu Bar during your current eCo.Repair session.

Your Security Check takes the form of a Memorable Information test, where you have to enter three characters or numbers at a specified position within your Memorable Information.

You perform circuit looping by:

1.	Select from the three-drop down menus the characters in your Memorable Information which correspond to the number displayed above the drop down menus.

Note: The sequence of numbers displayed above the drop down menus are randomly generated.

Note: Your Memorable Information could be a word, for example, sunshine01, so the 2^rd, 6^th and 8^th characters would be u, i and e.

You can change your Memorable Information, see GETTING STARTED, how to CHOOSE SETTINGS, how to Choose Security Check Settings.

2.	Select the Continue button. The Looping Menu window will be displayed.

How to Perform Kilostream Circuit Looping

	2.		Selecting the Submit button.

The following window is displayed whilst validation takes place:

Validation ensures that the circuit you are trying to loop belongs in your inventory.
Both the Customer Name and the A and B End Addresses will be displayed. Also, if there is an open fault against the circuit the fault details will be displayed.
Looping is not permitted on circuits that have open faults raised against them unless the status is:
	§	Cleared fault waiting Customer Confirmation
	§	Cleared fault awaiting Closure.

If a Fault Exists: (looping NOT permitted)		If a Fault Exists: (looping permitted)
The following message is displayed:		The following window is displayed: After circuit validation: You have now started the looping process, for further details about applying a loop, proceed through this section.
Select the OK button.
And the Circuit Status and Circuit Details window is displayed: Select the Cancell button.

Notes:
1.	Please be aware it can take up to 2 minutes to apply a loop. If a loop fails a detailed error message will be displayed advisingyou whether or not to re-attempt to apply a loop.
2.	It is possible that a node displaying looping capabilities in eCoRepair does not support looping. When this event occurs, please read the following explanation.
		“The network architecture that supports network looping of wideband Local Exchange Equipment (LTEs) and Customer Sited Equipment (NTEs) is complex; and relies on BT’s network control systems communicating with a number of record systems:
		§	site location,
		§	circuit ownership,
		§	equipment type records.
		to successfully apply and remove a loop at the required location - all these systems must align.
		The looping capability for wideband is still relatively new and BT is working to improve its performance in terms of speed of response and success rate in applying loops. Currently it can take 2-minutes to apply a loop for both BT and eCoRepair customer with a success rate of about 60% of loops successfully applied. For the duration of the inter-working tests, please inform BY of any loops that fail to apply so these can be investigated.”

10.	Select the OK button. You will be returned to the Diagnostic Menu window.
