4.2 Definitions
4.2.1 Carrier
Refer to the Telecommunjcapons Act 1997.
4.2.2 Customer Equipment
Refer to the Telecommun,cahons Act 1997.
4.2.3 Facility
Refer to Section 374(2) of the TeIecommuntca1ons Act 1997
4.2.4 Line Port
A port on CE for connection to the Metallic Local Loop.
4.2.5 Line Terminating Equipment
Une terminating equipment incorporates circuitry that applies an online condition to the PSTN line. CE incorporating this functionality may be associated with the line as:
(a) the only line terminating equipment connected to a line, to provide the sole termination of that line: or
(b) one or more parallel items of line terminating equipment. one or all of which can be used to terminate the line: or
(C) one of a number of items of line terminating equipment, which can be used alternatively to terminate the line. e.g. for
alternative voice/data applications.
4.2.6 Metallic local loop
Metallic twisted pair communications wire in a carrier’s network that provides connectivity between a customer’s premises and equipment in a Telecommunications Network.
4.2.7 Off-hook See On-line.
4.2.8 On-line
The state of the Line Terminating equipment when ii nas an electrical configuration that causes the current in the basic network loop to be at its maximum steady-state value. Can also be described as ‘off-hook’.
4.2.9 Pub’ic Switched Telephone Network (PSTN)
That part of the Telecommunications Network which enables any customer to establish a connection (or voice frequency communication with any other customer either automatically or with operator assistance.
Note: The PSTN has a nominal transmisson bandwidth of 3 kHz.
4.2.10 Ring-in/Loop-out PSTN line
