Various aspects of apparatuses and methods for enabling a subscriber premise network interface device (NID) to facilitate communication services including digitally derived voice services to be facilitated between a central office and a subscriber premise are disclosed herein. In accordance with one embodiment of the disclosures herein, such a method includes facilitating a downstream DSL voice channel transmission process at a subscriber premise Network Interface Device (NID) and facilitating an upstream DSL voice channel transmission process at the subscriber premise NID. The downstream DSL voice channel transmission process facilitates converting a voice component of a downstream DSL data stream to a corresponding downstream analog voice signal. The upstream DSL voice channel transmission process facilitates converting an upstream analog voice signal to an upstream voice component of an upstream DSL data stream.

Facilitating digital subscriber line services via a subscriber premise network interface device

A method for a system including a plurality of encoders each for receiving a first signal and encoding to generate a respective second signal for sending to a respective subscriber, comprising receiving, in each encoder, the first signal from a first source, while testing a signal path between a second source and the encoders, the first source on a first assembly, the second source on a second assembly, and each encoder on a respective third assembly, while each encoder is receiving the first signal from the first source, receiving, in each encoder, a third signal from the second source, generating, from each encoder, a fourth signal based on the third signal, the fourth signal being a redundancy signal and receiving and examining the fourth signal at the second source and subsequently receiving the first signal from the second source.

Communication system having enhanced reliability

A system and method for enhancing reliability in a communication system. In the system and method, redundant signal paths are continuously tested to determine if any faults are present while the operating signal paths are in use. If any faults are present in the redundant signal paths, they can be addressed while the operating circuits are still in use. This minimizes the chance that a switch from an operating signal path to a redundant signal path because of a fault in the operating circuit will result in downtime.

System and method for ensuring operations of redundant signal paths in a communication system

A method and apparatus for controlling command line transfer to a network element. The method and apparatus allow for transfer of command lines such as command lines in the Transaction Language 1 syntax, to a designated network element based upon a wait duration as well as based upon the maximum number of outstanding command lines for which acknowledgement has not yet been received from the network element to whom the command line was directed. As long as the maximum number of outstanding unacknowledged command lines is less than the maximum number set, command lines are transferred to the network element after waiting an amount of time equal to the wait duration. The overall result is that command lines can be directed to network elements with assurance that the commands will be properly executed by the network element. Furthermore, the network element can, to the extent that the command line causes a change in an equipment database associated thereto, appropriately modify the equipment database in the network element and cause such information to be transferred to an overall equipment database containing similar information for all network elements under the control of a network management system.

Method and apparatus for controlling command line transfer to a network

A line unit, used in a line shelf having a line shelf processor and common logic, is provided with an EEPROM device for storing information relative to the line unit. The stored information includes line unit type identification codes, auto provisioning data, gain and equalization adjustment data and signaling translation tables. The data contained within the EEPROM may be utilized by the line shelf processor to provide automatic initialization and provisioning of the line unit when first inserted into the line shelf, and automatic signaling translation so that line unit signaling becomes compatible with a transmission facility connected to the line shelf. The need for factory preset resistors installed in the line unit may be eliminated by storing within the EEPROM a required gain setting.
