In one embodiment, a cable distribution system includes a head end connected to a plurality of customer devices through a transmission network that includes a remote fiber node that converts digital data to analog data suitable for said plurality of customer devices. The remote fiber node includes a processor. The remote fiber node resetting software applications of a control plane of the remote fiber node in a manner free from impacting providing services to the customers as a result of resetting software applications. The remote fiber node executing the reset software applications.

Reset system for a remote physical device

A cable distribution system that includes a head end connected to a plurality of customer devices through a transmission network that includes a remote fiber node that converts digital data to analog data suitable for the plurality of customer devices. The remote fiber node includes a processor. The remote fiber node receives a software image containing (i) a hardware image, (ii) a primary boot loader, (iii) a kernel, (iv) a software dataplane for a dataplane, and (v) software applications for a control plane. Based upon the file name of the software image selectively using at least some of (i) a hardware image, (ii) a primary boot loader, (iii) a kernel, (iv) a software dataplane for a dataplane, and (v) software applications for a control plane, in resetting the remote physical device.

Present disclosure describes the techniques for regaining synchronization between the RPD and the PTP server, without resetting RPD, in the event of run time-phase jump experienced at RPD. To do so, said technique discloses identifying a run time phase jump event at a remote Physical device (RPD) and initiating an Upstream Channel Descriptor (UCD) refresh procedure to reconnect the RPD with Precision Time Protocol (PTP) server.

Techniques for allocating channel frequencies in remote physical device. The channel frequencies are sorted in a predefined order, wherein each channel frequency has a symbol rate. Further, the channel frequencies are grouped into one or more channel groups, wherein each channel group comprises one or more channel frequencies. The one or more channel groups are prioritized from highest priority to lowest priority. Further, the one or more channel frequencies are allocated starting from highest priority channel group to largest size window based on available slots in the largest size window and till a difference between last channel frequency and first channel frequency falls within frequency span limit of the largest size window. Further, prioritizing and allocating are repeated till remaining one or more channel frequencies of the one or more channel groups are allocated to next available windows or the next available windows are exhausted.
