摘要： A network interface device (NID) and associated printed circuit board is provided that includes metallic die cast housing and doors configured so that one of the doors, when closed, physically separates service provider circuitry from the customer premise equipment (CPE) side connections on a circuit card within the NID so that an end-customer may access the CPE side connections while the service provider circuitry remains secured from end-customer access. Moreover, the metallic housing provides increased physical strength and tamper resistance, including improved heat dissipation properties to radiate internal heat build-up more efficiently. The NID may be configured to provide insertable interface cards to permit flexibility in service provisioning and includes options for a type-200 T1 module, a type-400 T1 module, a type-200 high bit rate Digital Subscriber Line (HDSL) module, a type-400 HDSL module or an ISDN module.
