scope:

This standard provides the signaling requirements associated with analog voicegrade switched access lines that use loop-start and ground-start signaling. In this standard, the public switched network is referred to as the Network and the customer premises cabling and equipment is referred to as the Customer Installation (CI).

The interface between the Network and the CI is referred to as the Network Interface (NI). The NI is the same as the demarcation point defined in TIA-968-A, Technical Requirements for Connection of Terminal Equipment to the Telephone Network (formerly known as FCC Part 68).

The network applies two basic types of loop-start and ground-start signals at the NI:

♦ Normal telecommunications system voltages and currents.

♦ Voltages and currents due to maintenance activities.

The normal signals are specified in this standard. Maintenance signals are described in Annex A. Abnormal voltages and currents that are the result of the environment (e.g., induced voltages and currents, or lightning) are not covered in this standard.

This standard covers only those characteristics of loop-start and ground-start switched access line interfaces that are used by the network and the CI to establish calls using the public switched network. Other signals produced by supplementary features that are either associated with or independent of the basic signaling interfaces covered by this standard may appear at the NI. Examples of supplementary features directly associated with loop-start or ground-start signaling are line-side answer supervision, distinctive alerting, calling number delivery, calling name delivery, and visual message waiting indication. Meter reading is an example of a supplementary feature that is independent of the basic interfaces described in this standard. The characteristics of some supplementary features are contained in the following American National Standards:

♦ T1.401.01-2000 (R2005), Network to Customer Installation Interfaces - Analog Switched Access Lines Using Loop-Start or Ground-Start Signaling with the Line-Side Answer Supervision Feature.1

♦ T1.401.02-2000 (R2005), Network-to-Customer Installation Interface - Analog Voicegrade Switched Access Lines with Distinctive Ringing Features.1

♦ T1.401.03-1998 (R2005), Network-to-Customer Installation Interfaces - Analog Voicegrade Switched Access Lines with the Calling Number Delivery, Calling Name Delivery, or Visual Message- Waiting Indicator Feature.1

♦ T1.401.04-2000 (R2005), Network to Customer Installation Interfaces - Analog Voicegrade Switched Access Lines with the Call Waiting, Distinctive Call Waiting, or Calling Identity Delivery on Call Waiting Feature.1

♦ T1.401.05-2000 (R2005), Network-to-Customer Installation Interfaces - Analog Voicegrade Switched Access Lines with Network-Implemented Coin-Operated Payphone Feature.1

This standard does not cover party-line service or the CI-provided loop-start supervision associated with Private Branch Exchange (PBX) off-premises station lines. The characteristics of CI-provided loop-start supervision are contained in T1.407-1997 (R2006), Network-to-Customer Installation Interface - Analog Voicegrade Special Access Lines with Customer Installation-Provided Loop-Start Supervision.

At the time of publication, the editions of the American National Standards indicated above were valid. All standards are subject to revision and readers are encouraged to investigate the possibility of using the most recent edition of the standards indicated above.

Tariffs, contracts, or regulatory acts in various jurisdictions may contain additional or more stringent requirements than those in this standard.

Purpose

The purpose of this standard is to assist manufacturers and users of equipment used in the network or of products to be connected to the network to understand the characteristics of carrier networks when loop-start or ground-start signaling is used on analog switched access lines. The interface requirements in this standard may be useful in minimizing incompatibility problems although this standard is not intended to be an equipment specification.
