Where there is more than one FN1000 / FN5000 site within the same charge group Local Networking allows calls between such sites in the same charge group on the standard FN5000 access tariff or FN1000 access tariff to be uncharged. Charges for this feature are included in Access charges outlined in this Part.

National Networking Channels (NNCs) are required in order for OnNet calls between sites in different charge groups on the standard FN5000 access or FN1000 access tariffs to be uncharged.

National Networking Channels between two Charge Groups are not available unless each Charge Group has at least one customer FN5000/FN1000 site (excluding Remote Break-In and Remote Break-Out). All Featurenet Sites in a Charge Group can share standard application NNCs for OnNet calls and Remote Break-out calls.

National Networking between two Charge Groups can be extended to another by ordering National Networking Channels from only one of the first two Charge Groups to the third Charge Group (i.e. it is not necessary to fully interconnect all three Charge Groups). Such extended networking can be used to connect up to four different Charge Groups by serial linking of three sets of National Networking Channels.

For explanation of Charge Group structures, see Section 2, Section Endnote

Overflow calls are calls which become OffNet because insufficient National Networking Channels or Featurenet 1000 Access Lines have been chosen to carry them OnNet. When a route of National Networking Channels is first set-up, the customer can opt for overflow or no overflow from that route (default is overflow).

Remote Break-Out is provided for calls to break-out onto the PSTN in the Charge Group in which break-out is required and to adjacent Charge Groups to the Break-Out Charge Group.

On rental based networks a remote break out call will use existing NNC capacity from originating to destination charge group, and will then be charged as a local Off-Net call. The appropriate Off-Net call discounts will apply as outlined below in Off-Net Call Charges.

* Subsequent additions of National Networking Channels to existing routes will not incur additional Remote Break-out set-up fees. Where Remote Break-Out is required from an NNG to a different NNG in the same Charge Group, no National Network Channels are required.

Not available with Rental Based Charging Options for networking.

On-Net calls made solely within a site are non-chargeable. On-Net calls made between sites (including small sites) are charged as follows:-
