    ABSTRACT: This document replaces TA-NWT-001250.

    GR-1250, Generic Requirements for Synchronous Optical Network (SONET) File Transfer, Issue 2, replaces Issue 1.

    Synchronous Optical Network (SONET) Network Elements (NEs) can use the SONET Operations Communications Network in a standardized way
    for network management. Two management applications that are enhanced by the use of File Transfer protocol are software download and
    memory restoration processes. In the past, software download for transport NEs has usually been done locally, with an operator loading
    the software from a medium such as a floppy disk.

    Typically, a new generic will also require a corresponding hardware change, and, therefore, a craft dispatch. Digital Cross-Connects
    (DCSs) can have line-by-line configuration table changes made automatically by an Operations System (OS). Backups are done locally to
    nonvolatile memory, and remotely on a command-by-command basis. There are several problems with these methods. Line-by-line
    configuration table downloads and command-by-command backups are inherently slow. Nonvolatile memory is not sufficient to provide
    backup if the NE is physically lost (as in a fire or flood, for example).

    On a going forward basis, newer NEs may store only software load identifiers and generic identifiers in local memory; the backup
    copy may be stored separately. As more and more intelligent network elements are deployed, software download and remote backup of these
    NEs will consume proportionately more network provider resources. Use of a file transfer protocol such as the Open Systems
    Interconnection (OSI) File Transfer, Access, and Management (FTAM) protocol for SONET NEs can help alleviate these problems.

    This GR includes the Telcordia view of proposed generic requirements for the support of FTAM in SONET NEs.

    Issue 2 shows the coupling between this GR and related requirements in GR-253. Issue 2 also adds new requirements for using the
    FTP file transfer protocol to provide SONET file transfer applications (see Section 3.3). Issue 2 also provides additional details with
    respect to the CMISE information models required (Section 3.4), and also considers requirements that apply when using the TL1
    Interactive Class protocol (Section 3.5).

    When using GR-1250, you may need to refer to GR-253, GR-1042, SIF-011, SIF-022, and/or ISO 8571. You may also want to refer
    to GR-472, GR-836, GR-2915, GR-2963, and/or SIF-025.
