Program *10 provides two QSTU2, RSTU, KSTU2, RDSU, PSTU, or PESU ports to be assigned
to interface with central office E911 trunks.
E911 enhanced operation provides locator information to the responding agency to provide more
complete name and address information, including building, floor, etc. This is done by sending the
station number of the 911 caller to the E911 emergency center. This locator information is then
cross referenced with name/number/address data in the E911 central database, and the E911
operator receives the precise location along with the basic information.
The Strata DK14, DK40i and DK424 accomplishes this through a special interface between the
KSU and the CO. This special interface takes the station number information and sends it through
the public network in a format compatible with the central E911 database. This special interface is
required in addition to sending software within the Strata DK.
The required interface is an external device (Telident or Proctor) that interfaces to up to two
standard analog station ports.
