Indicates whether this converter is the local unit plugged into the managed rack, or its remote counterpart at the far end of the HDSL link. Admins use this to distinguish which end of a point-to-point HDSL pair a given row's status and configuration data describes, since the local and remote units of the same link appear as separate rows. When troubleshooting a link, an admin checks both the row where mdmPosition is local(1) and the paired row where it's remote(2) to compare status at each end.
