Every great movie franchise has at least three installments (think The Naked Gun), and so too does every great series on Logical Circuit Provisioning. So it is with extreme heartbreak and unbelievable anguish that we conclude this trilogy — a trilogy described by some as “the decade’s must-read” and by others as “bold” and “breathtaking”.

Based on the fan mail received, we know you have been touched deeply by both Having Fun with Logical Circuit Provisioning and Having (Even More) Fun with Logical Circuit Provisioning. We can only hope that this conclusion lives up to the high bar we set in the previous two entries.

In the first article, we demonstrated how to provision a new circuit. In the second article, we demonstrated how to reprovision an existing circuit. So we know that the basics work. But does it really save time? We recently deployed the Logical Circuit Provisioning customization to a large client for testing. We wanted the “subject matter experts” to judge for themselves how much time was saved.

In the case study below, we will reprovision circuit 5606.01.

This is a logical circuit that holds 22 DS0s and traverses through four systems: COJC-A, CRAG-O12, ERIE-DN1, and FOPS-O48.

We will be changing the channel slot that this circuit is designated to on COJC-A. It is currently on OC012-003-01-00, as shown in the screenshot below.

(Note that we have intentionally skipped a couple of steps to conserve space. If you’re unsure how we got here, just go back to the second article in this series.)

The original circuit, 5606.01, had a status of Inservice. For any status other than Reserved, the original circuit (5606.01) must be archived and then reprovisioned with a new circuit ID (5606.02). Right now, 5606.02 is currently on OC012-003-01-00. The field technicians need to put it on OC012-003-07-00. This is the third STS, seventh VT slot — in the screenshot above, it is six spots below the current location.

The problem we solved is that it’s difficult, and very time-consuming, to reprovision each of the 22 “child” logical circuits slotted within the 5606.02 circuit. Our application allows an engineer to easily move the “parent circuit” to the new position, and all of the “child” circuit’s designators will be moved along with it on the COJC-A system.

To make the move, we select the system. Note that when we do, the VT dropbox is enabled.

If we select a value of 7 from the VT dropdown and click the Update button, the channel designator is moved to the new slot. The real time-saver here is all of the DS0s provisioned within the 5606.02 logical circuit have been automatically moved along with it, eliminating the need to reprovision these circuits individually.

The final step is to save the circuit.

After that, we can search for circuit 5606.02 using the Logical Circuit Search tool:

If we select the circuit and click the Load Circuit button, the Logical Circuit Manager window appears. Note that the highlighted area in the screenshot below shows the new designator OC012-003-07-00.

It’s just that easy, and just that awesome! What would normally take a couple of hours now takes a couple of seconds.
