ABSTRACT: This document provides the Telcordia view of generic technical requirements for Voice Grade Special Access (VGSA) Services and
IntraLATA Private Line Services (IPLS) offered by Local Exchange Carriers (LECs) to their customers.
The document distinguishes between service features, defines valid interfaces for the services described, and provides transmission
performance parameter limits used when assessing the quality of the channel over which the service is delivered. The services
described are presented in sufficient technical detail to help a customer to select an appropriate configuration for incorporation into
an end-to-end communications channel.
The transmission requirements and limits provided are applicable to the portion of the circuit contained on the network side of the
network interface (NI) or point of termination (POT). The NI and the POT are the physical points of demarcation between the LEC
facility and the customer's facility that establish the technical interface and division of responsibility. The document is not
intended to provide specific ordering information. Customers must interface with their service provider to determine which options and
configurations are available in their respective area of operations.
