Network Interface Device 2.7.1 The NID is defined as any means of interconnection of the End User’s customer premises wiring to BellSouth’s distribution plant, such as a cross-connect device used for that purpose. The NID is a single line termination device or that portion of a multiple line termination device required to terminate a single line or circuit at the premises. The NID features two independent xxxxxxxx or divisions that separate the service provider’s network from the End User’s premises wiring. Each chamber or division contains the appropriate connection points or posts to which the service provider and the End User each make their connections. The NID provides a protective ground connection and is capable of terminating cables such as twisted pair cable.
