Abstract

A directional terminal adapter has a housing and a reversible faceplate. Distribution cables of a cable network are connected to the housing and conduct downstream and upstream signals through the housing. Signals flow through the faceplate in a predetermined direction. Reversing the orientation of the faceplate with respect to the housing reverses the direction of flow of the upstream and downstream signals through the directional terminal adapter.

Claims

1. A directional terminal adapter for use in a cable network, the cable network having a plurality of distribution cables which carry both upstream and downstream signals, comprising:

a housing having a first receiver port and a second receiver port, each of which connects to one distribution cable;

a detachable faceplate which attaches to the housing, the faceplate having an exterior side and an interior side;

an upstream contact point on the interior side of the faceplate, the upstream contact point communicating upstream signals to one of the receiver ports when the faceplate is attached to the housing; and

the faceplate attaching to the housing in one of two orientations, the receiver port in communication with the upstream contact point being different between the orientations.

2. A directional terminal adapter as defined in claim 1, further comprising:

a downstream contact point on the interior side of the faceplate, the downstream contact point communicating downstream signals to a different receiver port than the receiver port receiving upstream signals from the upstream contact point when the faceplate is attached to the housing;

circuitry for processing signals attached to the interior side of the faceplate, the circuitry in communication with both the upstream contact point and the downstream contact point; and

wherein;

downstream signals from the receiver port in communication with the upstream contact point are routed through the circuitry to the downstream contact point and associated receiver port, and upstream signals from the receiver port in communication with the downstream contact point are routed through the circuitry to the upstream contact point and associated receiver port.

3. A directional terminal adapter as defined in claim 2, further comprising:

at least one coaxial connector attached to the exterior of the faceplate and in communication with the circuitry of the faceplate, and wherein;

upstream signals entering the circuitry from the at least one coaxial connector pass through the upstream contact point to the one of the receiver ports in communication with the upstream contact point and do not pass through the downstream contact point.

4. A directional terminal adapter as defined in claim 3, wherein the upstream and downstream contact points are spaced equidistant from the center of the faceplate, the adapter further comprising:

two conducting points attached inside the housing, each conducting point in communication with one of the receiver ports of the housing, the two conducting points spaced equidistant from the center of the housing, each of the two conducting points in conductivity with one of the contact points when the faceplate is attached to the housing, and wherein;

the one of the two contact points with which each of the conducting points is in conductivity is different between the first orientation and the second orientation of the faceplate with respect to the housing.

5. A directional terminal adapter as defined in claim 4, further comprising:

at least one insulating device which is attached to the housing and which electrically insulates at least one conducting point from the housing.

6. A directional terminal adapter as defined in claim 4, further comprising:

a bypass bar assembly within the housing which creates an electrical connection between the two conducting points when the faceplate is detached from the housing, the bypass bar assembly breaking the electrical connection it previously created when the faceplate is attached to the housing, and wherein;

signals traverse the bypass bar assembly between the two receiver ports to allow communications between the two receiver ports when the faceplate is detached from the housing.

7. A directional terminal adapter as defined in claim 2, further comprising:

a signal direction indication on the faceplate which indicates the direction of one of the downstream or upstream signal flow through the directional terminal adapter.

8. A method of reversing flow directions of both upstream and downstream signals conducted by cables through a directional terminal adapter in a cable network, the terminal adapter having a faceplate and directional circuitry which permits the upstream and downstream signals to flow in one respectively opposite relationship, the method comprising:

moving the faceplate from one orientation of attachment to the housing to another different orientation of attachment to reverse the flow directions of both the upstream and downstream signals in the cables; and

conducting the upstream and downstream signals from the cables through the directional circuitry in the one permitted flow relationship in either orientation of attachment of the faceplate.

9. A method as defined in claim 8, further comprising:

indicating the direction of signal flow of one of the downstream signals or the upstream signals on the faceplate in either orientation of attachment of the faceplate.

10. A method as defined in claim 8, wherein the faceplate comprises coaxial connectors for connecting subscriber cables between the directional terminal adapter and subscribers, the subscribers originating upstream signals which enter through the coaxial connectors, the method further comprising:

conducting the downstream signals from the directional circuitry to the coaxial connectors; and

conducting subscriber originated upstream signals from the subscriber through the coaxial connectors and to the directional circuitry to the cables in the same direction as the upstream signals.

11. A method as defined in claim 8, wherein the housing further includes a bypass assembly for conducting upstream and downstream signals through the housing between the cables and the faceplate is detachable from the housing, the method further comprising:

detaching the faceplate from the housing while moving the faceplate from one orientation to the other orientation;

activating the bypass assembly to conduct the upstream and downstream signals through the terminal adapter between the cables when the faceplate is detached from the housing; and

deactivating the bypass assembly when the faceplate is attached to the housing.
