§  10.430   Character limit.

   A Participating CMS Provider must support transmission of an Alert
   Message that contains a maximum of 360 characters of alphanumeric text.
   If, however, some or all of a Participating CMS Provider's network
   infrastructure is technically incapable of supporting the transmission
   of a 360-character maximum Alert Message, then that Participating CMS
   Provider must support transmission of an Alert Message that contains a
   maximum of 90 characters of alphanumeric text on and only on those
   elements of its network incapable of supporting a 360 character Alert
   Message.
