421 * Country code first byte, then manufacturer is last two bytes. See T.35.
422 * Apparently Germany issued some manufacturer codes before the two-byte
423 * standard was accepted, and so some few German manufacturers are
424 * identified by a single manufacturer byte.
425 *
426 * T.30 5.3.6.2.7 (2003) states that the NSF FIF is transmitted
427 * in MSB2LSB order. Revisions of T.30 prior to 2003 did not
428 * contain explicit specification as to the transmit bit order.
429 * (Although it did otherwise state that all HDLC frame data should
430 * be in MSB order except as noted.) Because CSI, TSI, and other
431 * prologue frames were in LSB order by way of an exception to the
432 * general rule (T.30 5.3.6.2.4-11) many manufacturers assumed that
433 * NSF should also be in LSB order. Consequently there will be
434 * some country-code "masquerading" as a terminal may use the
435 * proper country-code, but with an inverted bit order.
436 *
437 * Thus, country code x61 (Korea) turns into x86 (Papua New Guinea),
438 * code xB5 (USA) turns into xAD (Tunisia), code x26 (China) turns
439 * into x64 (Lebanon), code x04 (Germany) turns into x20 (Canada),
440 * and code x3D (France) turns into xBC (Vietnam).
441 *
442 * For the most part it should be safe to identify a manufacturer
443 * both with the MSB and LSB ordered bits, as the "masqueraded" country
444 * is likely to not be actively assigning T.38 manufacturer codes.
445 * However, some manufacturers (e.g. Microsoft) may use MSB for the
446 * country code and LSB for the rest of the NSF, and so basically this
447 * table must be verified and corrected against actual real-world
448 * results.
