A device input unit, used by system administrators of this device for input traffic counters.

Usage: For example, a disk drive might use 'mediaBlock'.

Usage: Thanks to XCMI WG members for stimulating the following discussion. There are three reasonable ways for using the 'xcmHrDevTraffic[Input|Output]Unit' objects: a) 'read-only' and set up by the management agent according to the sole appropriate (fixed) units at time of row creation; b) 'write-once' by the management station, at time of row creation (possibly selecting from among several possible valid units); and c) 'write-many' by the management station (to dynamically request the management agent to 'convert' the 'xcmHrDevTraffic[Input|Output]Count' objects into the appropriate units). Conforming implementations need NOT support more than one of the above three scenarios.

Usage: 'mediaImage' - SHOULD be used ONLY for softcopy INPUT page images (scan, copy, fax, etc.). 'mediaImpression' - SHOULD be used ONLY for hardcopy OUTPUT page impressions (print, copy, fax, etc.) 'mediaSheet' - SHOULD be used ONLY for hardcopy OUTPUT and does NOT always equal output pages (e.g., duplex or N-up printing).
