Abstract: A plurality of data blocks are encrypted in accordance with an encryption scheme that transforms a data block into an encrypted data block by: performing a bit modification operation on the data block using one or more logic blocks generated for the data block to thereby generate a first intermediate state data block; performing a bit remapping operation on the first intermediate state data block using at least one encryption screen to thereby generate a second intermediate state data block; and performing a bit modification operation on the second intermediate state data block using one or more logic blocks generated for the data block to thereby generate the encrypted data block. The encrypted data blocks may then be decrypted in accordance with a decryption scheme that applies at least one decryption screen and the same logic blocks that were used in the encryption scheme.

Abstract: A splitter card having integral test access devices. The splitter card allows test access to be readily provided at any location where splitter cards are typically mounted (e.g., a splitter chassis).

Abstract: A splitter card including a circuit board on which line, data and voice connectors are mounted. The connectors include contacts electrically connected to termination posts that extend through the circuit board such that ends of the termination posts are exposed. A plurality of splitters are connected to the circuit board for splitting composite signals into voice and data signals. The circuit board includes conductive paths for directing composite signals from the line connector to the splitters, for directing voice signals from the splitters to the voice connectors, and for directing data signals from the splitters to the data connectors. Dielectric insulator members are connected to the circuit board to cover the exposed ends of the termination posts.

Abstract: A front access splitter assembly that fully supports lifeline POTS and lifeline ISDN (Integrated Services Digital Network) service requirements is shown and described in this disclosure.

Abstract: A cable management bracket for a telecommunications rack. The bracket includes an elongated member having a length sized to extend across a width of the rack. A plurality of fingers project outwardly from the elongated member. The fingers are spaced apart along the length of the elongated member. Gaps sized to receive telecommunications cables are positioned between the fingers. Bend radius limiters are preferably connected to the fingers to prevent cables passing through the gaps from being bent beyond predetermined bend radius requirements.

Abstract: A protective panel for use in a splitter chassis is described in this disclosure. The protective panel is configured to at least partially cover a splitter card that would otherwise be exposed but for the presence of the panel.

Abstract: A telecommunications splitter assembly. The assembly includes a chassis in which a plurality of vertically spaced-apart splitter cards are mounted. A card-retaining bracket is fastened to an open end of the chassis to retain the cards within the chassis. The card-retaining bracket includes card support structures that extend beneath the cards to inhibit the cards from bowing.
