5.13 Dedicated Voice Services

Telecom’s Dedicated Voice Services provide a dedicated circuit linking two locations together for voice traffic. The ends of the circuit can either both be situated within the same local calling area (for example both ends in the Wellington local calling area) or they can be in different local calling areas (for example one end in the Wellington local calling area and the other in the Auckland local calling area).

The specific voice services are

• PBX Tieline Service (see section 5.13.2)
• Metrolink Service (see section 5.13.3)
• Distant and Remote PBX Extension Services (see section 5.13.4)
• Shoutdown/Ringdown Service (see section 5.13.5)

A range of access options and interfaces is available for these services, including a purely digital interface for PBX Tielines and Metrolink Service — Digital Voice Access (see section 5.13.1). The following information on Digital Voice Access (section 5.13.1) applies to all PBX Tielines and Metrolink Service circuits.

5.13.1 Digital Voice Access

Digital Voice Access (also known as Fractional E1) is an access option which enables a range of Telecom Network Services to be provided via a single 2 Mbit/s digital interface. As Digital Voice Access is an access option only, it is only sold in conjunction with another Telecom network service. There are no transmission or usage charges associated with Digital Voice Access as these are charged in conjunction with individual network services.

Public Switched Telephone Network (PSTN) Access via Digital Voice Access

Standard PSTN telephone trunks can be provided in conjunction with other Dedicated Voice Services over a Digital Voice Access. PSTN access is from the central exchanges in the main centres.

These exchanges are:

• Airedale Street
• Mayoral Drive
• Remuera
• Hamilton Central
• Frankton (from late 1992)
• Palmerston North
• Wellington Central
• Courtenay Place
• Lower Hutt
• Christchurch
• Riccarton
• Dunedin (from late 1992)

PSTN access is only available when provided in conjunction with other Dedicated Voice Services. See Sections 5.13.2 to 5.13.5.

The usual charges and conditions for the Digital Voice Access apply (see below), and the access charge per PSTN trunk is the same as the standard line rental charge for business customers (see Section 1.3.1 Business Rates). Charges for other PSTN services also apply (see Sections 1 and 2).

Installation Charges

The installation charge is independent of the number of 64 kbit/s channels involved in the link to the customer. The installation charge for a circuit up to 2 km from the local exchange is based on the actual costs involved, but will not exceed a predetermined maximum charge.

• Maximum charge per end of link... $7500.00

For installing access circuits further than 2 km from the local exchange, there will be an additional charge to the customer. This charge will be determined by the local Telecom Regional Operating Company and will be based on the costs of providing the link.

• Charge, per channel, for additional channels added to an existing Digital Voice Access... $150.00

Note:
No additional installation charges are charged for channels configured with the initial installation of the Digital Voice Access.

Monthly Access Charges

Access charges for Digital Voice Access are composed of three charges.

• Charge for the Digital Voice Access service delivery point at a customer’s premises... $500.00
