This read-only enumerated value indicates whether this modem entry represents the locally managed unit plugged into the rack, local, or its far-end counterpart, remote. Admins use it to distinguish the two ends of a fiber link within the same table, since many attributes such as clock source, data rate, and framing apply per-end and a remote unit's settings often mirror or depend on the local one. For example, mdmPosition=local(1) marks the modem physically installed in the managed rack, while a linked entry with mdmPosition=remote(2) represents the modem at the far end of the fiber run.
