Place FTTP

The Place FTTP command automatically places a network interface device (NID) on each address found within the FTTP boundary and places a drop cable from that NID to the associated network access point (NAP). When selecting the Place FTTP dropdown in the Placement section of the Fiber tab, the following commands will be available:

Clicking the Place FTTP icon will open the Fiber To The Premise dialog which allows the user to define the NID (node) type, the drop cable, XSection, etc. of the drops which are placed while designing with this utility:

Select a Node Type. This device, usually called a NID, is placed on the side of the home for each address.
Select the Address Status for the Fiber drop.
Select a Drop Cable & Length. The drop is placed between the NID and the NAP.
Select a Xsection to be used with fiber cables.
Select the Fiber Quantity needed to feed each NID.
Select the Splice Type used to connect the NID and NAP.
Select the Drop Name to be used on the drops. (Address, or NAP name, or Both)
Select the boundary to execute the FTTP fiber design procedure.

Note: The FTTP Utility requires the following 8 conditions be met:

Link to strand must be on.
Addresses must be linked to the housecounts.
Housecounts must be linked to the poles/peds/enclosures. (When using Duct, housecounts and addresses must be manually placed. Enclosures act as poles/peds.)
The NAP must have capacity for the number of addresses it is feeding.
There must be an existing ‘FTTP boundary’.
There must be an LCC device within the fiber route. (Not necessarily in the boundary, but connected.)
There must be fibers dropped off at each NAP (for the drops) and all fibers must be connected all the way back to the LCC.
Addresses must be posted before running the FTTP utility. (All features inside the boundary should be posted.)

If no drops are being drawn from the NAP to the NIDs n the FTTP module, and the following error displays:

‘No drops processed due to lack of capacity’

…make sure that each splice which will be used as a NAP has the ‘NAP’ checkbox checked in the spec file definition for that splice. (Create a NAP4, a NAP8, NAP12 etc. and you will have the correct NAP to lay out for the exact number of addresses that will be connected).

Note: A designer CAN use NAPs with a defined capacity larger than the number of addresses it is feeding, but NOT a NAP with a defined capacity of LESS than the number of addresses it feeds.

Note: Any address that has a customer record will not be processed. If the FTTP utility was run previously, and the drops were deleted, those addresses would all have customer records and would not process. Those customer records would need to be deleted by deleting the address and placing it back in and then the FTTP utility could be executed again to process those addresses.

Note: See the instructions under the Fiber Modify/Delete section of the OpenComms Designer manual to use the FTTP delete command.
