Specify the bitmap options implemented in the transceiver as described in. The bits definition is: 5 RATE_SELECT is implemented NOTE: Lack of implemention does not indicate lack of simultaneous compliance with multiple standard rates. Compliance with particular standards should be determined from Transceiver Code. 4 TX_DISABLE is implemented and disables the serial output. 3 TX_FAULT signal implemented. (See SFP MSA) 2 Loss of Signal implemented, signal inverted from standard definition in SFP MSA. NOTE: This is not standard SFP/GBIC behavior and should be avoided, since non-interoperable behavior results. 1 Loss of Signal implemented, signal as defined in SFP MSA.
