No. 175

There are 5 charging steps for inter-zone charging, as shown below:

There are exceptions to this Step A to Step E principle for monthly transmission charges. The exceptions are:

• Loop Signalling Circuits (L1)—see section 5.5.
• Programme Circuits (P1 only)—see section 5.6.
• Telegraph Circuits (T1-T2)—see section 5.7.

Of these, only T1 and T2 leased-circuit services are available to new customers.

5.1.5 Alteration and Reconfiguration Charges

There are one-off charges for each alteration when a customer requests the alteration, reconfiguring or removal of leased circuits.

External removal of a circuit is defined as the moving of a circuit from one of a customer's premises to another.

Internal removal is defined as the moving of a circuit within the same premises.

Charges will be applied where alteration or reconfiguring of circuits requires a visit to a customer's premises. These charges will be negotiated between the Regional Operating Companies (ROCs) and their customers.

5.1.6 Other Charges

There are charges for the temporary lease of circuits, and for costs associated with the reconnection of circuits after disconnection.

There are also charges for special conditioning requirements and other services—see the appropriate subsections within this section (National Leased-Circuit Services) for details about these services and their charges.

5.2 Analogue Leased Circuits

The basic analogue leased-circuit service available from Telecom for new connections is a 2-wire unconditioned voice-grade circuit, operating between 300 and 3400 Hz.

The charges associated with this service are listed in sections 5.3 (Voice-Circuit Service) and 5.4 (Analogue Data Service). There are extra charges for enhancements to this basic service, and these are listed as Other Charges in sections 5.3.6 and 5.4.6.

5.2.1 Monthly Transmission Charges for Analogue Leased Circuits.

Transmission charges for analogue leased circuits are a combination of the Step A to Step E rates which were detailed in section 5.1.4. In general, this means:

• Junction charges apply to circuits or portions of circuits between exchanges in a local calling area.
• Step A rates apply to circuits or portions of circuits between local calling areas within a Tariff Zone.
• Step B to Step E rates apply to circuits or portions of circuits between Tariff Zones.

Additionally:

• Circuits between adjacent local-calling areas are charged at the Step A rate. This applies whether circuits are in the same tariff zones, or in different tariff zones. Junction charges may also apply.
• Circuits between non-adjacent local-calling areas (within a tariff zone) are charged twice the Step A rate. Junction charges may also apply.
• Circuits between tariff zones which do not involve adjacent local-calling areas are charged at the Step B to Step E rates, in addition to any junction or Step A rates which may apply to the intra-zone portions of the circuit.
• Where circuits terminate off exchanges other than the Tariff Zone Centre, some combination of Step A rates will apply, in addition to any inter-zone tariffs which may apply. Junction charges may also apply.

Exceptions to the above occur where demand has been sufficiently high to justify the installation of direct circuits. The exceptions are as follows:
