An apparatus used to interface to a communications network is provided. Specifically, the apparatus is for placement in a network interface device (NID). An interface module that may be used as a splitter and balun for telephone and data services is also provided. The interface module may include a housing containing a pivotal rearward extending portion, in which a bottom of the pivotal rearward extending portion is above a bottom of an adjacent portion of the housing providing an open region below the bottom of the pivotal rearward extending portion, at least one wire extending from a front portion of the housing and connecting a balanced pair of telephone wires from the telephone company to the customer premises, and a coaxial connector disposed on a side of the pivotal rearward extending portion.

In signal-splitting equipment for multiple subscribers, circuitry is disposed on a signal-splitter card which connects with a back plane providing physical support and electrical connection to other splitter cards and to distant sites, as well as to an interface with a system conducting automatic testing of DSL circuits. Each splitter card also carries a separate relay card with signal-routing relay circuitry, the relay card being affixed by means of a switching connector having bypass circuitry which ensures normal communication of DSL signals and audio signals in the event that a relay card is disconnected from its signal-splitter card. During a testing of the equipment, the system operates the relays of the relay cards of the respective signal-splitter cards for a connection of test equipment to various equipment associated with a specific subscriber.

An arrangement of plural filter circuits on a single card, and interconnection and mouthing of numerous cards on a single rack to facilitate maintenance, is provided for use in a telco. In each of the filter circuits, there is a first plurality of inductors connected in series in a first leg of a balanced line configuration of filter, a second plurality of inductors connected in series in a second leg of the balanced line configuration of filter, and a plurality of capacitors connected as cross branches between terminals of the inductors. A substrate supports the capacitors and the inductors, wherein each of the inductors is a toroidally wound inductor comprising a toroidal core of magnetic saturation inhibiting material. The saturation inhibiting core material allows reduction in size of a cross-sectional dimension of the core to approximately the cross-sectional dimension of one of the capacitors. For telco equipment, a set of connectors is mounted in a back plane of an enclosure for receiving the cards, and a plurality of bypass switches are disposed in the set of connectors for bypassing voice signals around corresponding ones of the cards. The bypass switches are placed in a state of conduction upon removal of a corresponding one of the cards from the set of connectors.
