Network Interface Device (NID) 2.7.1 The NID is defined as any means of interconnection of end-user 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 customer-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.
