/*
* Country code first byte, then manufacturer is last two bytes. See T.35.
* Apparently Germany issued some manufacturer codes before the two-byte
* standard was accepted, and so some few German manufacturers are
* identified by a single manufacturer byte.
*
* T.30 5.3.6.2.7 (2003) states that the NSF FIF is transmitted
* in MSB2LSB order. Revisions of T.30 prior to 2003 did not
* contain explicit specification as to the transmit bit order.
* (Although it did otherwise state that all HDLC frame data should
* be in MSB order except as noted.) Because CSI, TSI, and other
* prologue frames were in LSB order by way of an exception to the
* general rule (T.30 5.3.6.2.4-11) many manufacturers assumed that
* NSF should also be in LSB order. Consequently there will be
* some country-code "masquerading" as a terminal may use the
* proper country-code, but with an inverted bit order.
*
* Thus, country code x61 (Korea) turns into x86 (Papua New Guinea),
* code xB5 (USA) turns into xAD (Tunisia), code x26 (China) turns
* into x64 (Lebanon), code x04 (Germany) turns into x20 (Canada),
* and code x3D (France) turns into xBC (Vietnam).
*
* For the most part it should be safe to identify a manufacturer
* both with the MSB and LSB ordered bits, as the "masqueraded" country
* is likely to not be actively assigning T.38 manufacturer codes.
* However, some manufacturers (e.g. Microsoft) may use MSB for the
* country code and LSB for the rest of the NSF, and so basically this
* table must be verified and corrected against actual real-world
* results.
