Data channel rates are typically 2.4 or 9.6 kbit/s. There
are three standard transmission bit rates of 256, 512 and
1024 kbit/s with three different interfaces over which the
data can be transported. These are shown below. Some
countries also use non-standard rates. 285X can provide
all of these three interfaces, with IB5 and IB6 as options,
and Bit Error Rate Testing can be carried out. However,
there is no provision for framed Eurocom, nor for encryption.
Encryption can normally be turned off on the EUROCOM
equipment for test purposes.
