EMERs by Equipment Name.

Notes:

   1. For a general background to the EMER numbering system, see "EMERs - A
 Valuable Resource" on this web site.
   2. In the EMERs below, "x" stands for the Part Number.
   3. This list is a compilation of those EMERs which would, today, have been
 included in the three sections,
      Telecommunications, Communications Installations and Test and Measurement.
