CEPT interface
For the Conference of European Postal Communications (CEPT) interface,
the connection to the external digital carrier is through the NT5K85 DTI
cable assembly. It converts the 120 ohms D-connector to 75 ohms coaxial
cable. The impedance is switch set. The switch-settings table at the end
of this chapter describes the options. See
Table 332 "2 MB DTI switch
options" (page 788) .
If a coaxial interface is required, use NT5K85 in conjunction with the
NTBK05.
