Document Number TR-NWT-000335
Issue Number 03
Issue Date May 1993

    ABSTRACT: Voice Grade (VG) Special Access Services extend from an End-User Network Interface (EU-NI) to an Interexchange Carrier (IC) Point Of Termination (IC-POT), or from one IC-POT to another IC-POT in the same Local Access and Transport Area (LATA). There are twelve VG Special Access Services with predefined service features, transmission specifications, and interfaces, but a customer may also construct a Voice Grade Customized (VGC) service from option lists of transmission specifications and compatible interface combinations. IntraLATA Private Line Services (IPLS's) are applicable between two end-users' customer-provided terminal equipment and are wholly contained in one LATA.

    This Technical Reference (TR) describes VG Special Access Services and IPLS offered by Local Exchange Carriers to their customers. The TR provides the view of Telcordia on generic technical requirements, distinguishes between service features, and defines valid interfaces for the services described. The document describes VG Special Access Services and IPLS in sufficient technical detail to permit a customer to select an appropriate configuration for incorporation into an end-to-end communications channel.

    TR-NWT-000335 replaced TR-TSY-000335 and PUB-62501.
