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:-

* For Minimum Periods of one, three or five years and all Minimum Period Renewals see the applicable discounts stated in the Featurenet Contractual Information Part.

Featurenet Call-in is available on both UBC and Rental Based Networks.

On-net calls from Featurenet Call-In numbers are charged as follows. Minimum Period discounts do not apply to calls originating from Featurenet Call-In numbers.

OffNet calls are those public network calls made from FN5000 lines, FN1000 trunks, Hosted Voice Connect and Featurenet Call-In numbers. In rental based networks, calls made from FN5000 lines and FN1000 trunks to Featurenet Call-In numbers are also OffNet calls.

The feature can only be implemented or removed on a per customer basis, not a per line basis. Time Scale rates will apply to remove or add the feature.

There are a number of circumstances where ring back when free cannot be activated, e.g. access lines which are associated with MADN's, hunt groups, UCD groups, ACD groups, attendant consoles etc. Further information is available in the Featurenet Service Description.

The charge for the activation of RBWF will contribute to Call Commitment and will be included in the Volume Master call volume discount schemes. The charge is not subject to any other discounts.

Customers may choose to benefit from increased OffNet and OnNet call discounts in exchange for electing to commit to specific minimum average call spend levels across their network.

Featurenet Minutes contracts are applied in the following way:

• - Existing Access Line rentals are unchanged.
• - All access lines on a customers network benefit from the following specified discount levels.
• - All access lines on a customers network are subject to the per line commitment levels specified.
• - Any new lines added to a customers network while the minutes contract option is in force will automatically benefit from the same terms.
• - Minutes Contracts are subject to a 12 month Minimum Period. After this period customers may choose to revert to standard call commitment levels without reconcilliation charges. Customers who cease all of their Featurenet service before the minimum period has elapsed will be subject only to normal early termination charges (See Sub part titled pages 6 - 97 of this Part).
• - Existing Featurenet customers must have a least 6 months to run of their current Minimum Period to be eligible for 'Featurenet Minutes Contracts' .

For each Featurenet Access Line there is an associated commitment by the customer to meet a minimum level of call spend per line, averaged across the Customer's network. The quarterly call spend commitment level is calculated at the beginning of each quarter based on the number of lines in service on the first day of the quarter across all FN1000 and FN5000 access lines being rented by the customer. At the end of the quarter the total call spend is calculated for the customer (OnNet, Remote Break-Out and OffNet call charges, NNC rentals are all included in the call spend commitment calculations) and any short fall against the commitment level calculated at the beginning of the quarter is charged to a single account nominated by the customer.

For Minutes Contracts, as detailed below, this commitment covers spend on OnNet, Remote Break-Out, OffNet and/or NNC Rental charges.

Customers may choose to 'convert' their network to 'Minutes Contract' discounts at any time. Measurement of Minutes Contract Call commitment levels will commence following the first quarterly invoice after the customer has been converted to a Minutes Contract Option.

The level of commitment may vary, according to the type of Access Line, and is shown in the tables below.

For Minimum Periods of 3 or 5 years the appropriate discounts apply to the call commitment values shown below.

Customers may choose to benefit from increased OffNet and OnNet call discounts by selecting one of the Featurenet Call Volume Contracts. The schemes provide discounts based on spend thresholds on various types of calls.

There are two Volume Master Schemes which provide differing levels of call prices dependant on call commitment levels.

Volume Master contracts have a minimum 1 year term.

Volume Master Advantage - Provides specific call price rates subject to current call commitment levels on 21E tariff schemes.

Volume Master Premium - Provides enhanced call prices subject to increased call commitment levels.

Remote breakout calls from sites contracted on the schemes are treated as OffNet calls.

Customers may choose to contract their sites to a Call Volume Contract at any time. Call Volume Contract call pricing and measurement of call commitment levels will commence following the first quarterly invoice after the site has contracted to a Call Volume Contract.

N.B. These schemes cannot be used in association with Minutes Contracts, Corporate Lines tariffs or Local Organisation Lines.

For each Featurenet Access Line there is an associated commitment by the customer to meet a minimum level of call spend per line, averaged across the Customer's network. The quarterly call spend commitment level is calculated at the beginning of each quarter based on the number of lines in service on the first day of the quarter across all FN1000 and FN5000 access lines being rented by the customer. At the end of the quarter the total call spend is calculated for the customer (OnNet, Remote Break-Out and OffNet call charges, NNC rentals are all included in the call spend commitment calculations) and any short fall against the commitment level calculated at the beginning of the quarter is charged to a single account nominated by the customer.

For Call Volume Contracts, as detailed below, this commitment covers spend on OnNet, OffNet and /or NNC Rental charges.

For sites contracted to the Volume Master Advantage scheme current call commitment levels will remain in force.

For sites contracting to the Volume Master Premium scheme the call spend commitments detailed in the table below will apply.

For Minimum Periods of 3 or 5 years the appropriate discounts should be applied to the standard call commitment values and those shown below.
