Object
This attribute is the name of the file with the RxMER data for a
specified CM at the CMTS that is to be downloaded using TFTP to the
PNM server. This value can only be changed while a test is not in
progress. An attempt to set this value while the value of
'docsPnmCmtsUsOfdmaRxMerMeasStatus' is 'busy' will return
'inconsistentValue'.
If the value of this object is the DEFVAL (empty string), then a
default filename value will be used. Otherwise the value set will be
used as the filename.
If a default filename value is used, it is generated as the test name
plus a unique CCAP identifier (either a loopback address (IPv4 or IPv6)
or FQDN), plus the 'epoch time'. The epoch time (also known as 'unix time')
is defined as the number of seconds that have elapsed since midnight
Coordinated Universal Time (UTC), Thursday, 1 January 1970.
Hence, the format would be:
PNMCcapRxMER_<Unique CCAP Identifier>_<epoch>
For example: PNMCcapRxMER_ccap1.boulder.cablelabs.com_1403405123
The data file is comprised of a header plus the Histogram Data. The header
is comprised of ordered fixed-length fields. Unless otherwise specified,
the header fields contain hex values that are right-justified within the
field. If necessary the field is left-padded with zero values.
Syntax of the file is as follows:
File Type set to '504E4D69' (without the quotes) 4 bytes
Capture Time 4 bytes
ifIndex 4 bytes
Unique CCAP ID 256 bytes
CM MAC Address 6 bytes
Number of Averages 2 bytes
PreEq On or Off 1 byte
Subcarrier zero center frequency 4 bytes
FirstActiveSubcarrierIndex 2 bytes
Subcarrier Spacing in kHz 1 byte
Length in bytes of RxMERData 4 bytes
