Description: This object is used to enable/disable the gateway to override the NSF(Non-Standard Facilities) code in the following T.30 signals: NSF, NSC (Non-Standard Facilities Command) and NSS (Non-Standard Facilities Set-up). The NSF code is overridden to prevent the group 3 fax machines from synchronizing with each other on the basis of a protocol other the ITU T-series recommendations. If this proprietary synchronization is prevented, the group 3 fax machines will synchronize to the standard T-series protocol. This action is necessary if the fax relay capability of the media gateway is limited to the T-series recommendations. As defined in T.35, the NSF code consists of a one-byte Country Code, a two-byte Terminal Provider Code (also called the Vendor Code), and a variable-length (up to 255 bytes) Terminal Provider-Oriented Code. If t38NSFOverride is enabled, the Country Code and Terminal Provider Code are overridden with the values of the t38NSFCountryCode and t38NSFVendorCode respectively, while the Terminal Provider-Oriented Code (which is a bit-map of manufacturer-specific capabilities) is set to all-zeros.
