Description
The ADTRAN Total Reach DDS-R is a span-powered
termination unit designed to deliver data rates up to 64
kbps and provide testing functionality at the customer
premises. Used in combination with the TROCU DP
unit, the Total Reach DDS-R converts the 2-wire Total
Reach signal to the traditional 4-wire DDS signal for
presentation to the customer.
NOTE
The Total Reach DDS-R unit must be used with
an appropriate Total Reach TROCU DP unit.
The Total Reach DDS-R is an auto-rate adaptive
digital network interface at the customer premises
point-of-demarcation. In addition to terminating the
2-wire extended range signal, the Total Reach DDS-R
functions as a regenerative loopback device supporting
Telco-generated testing. The Total Reach DDS-R is
available in the T200 mechanics and can be optioned
for 0 or -10 dB output toward the customer.
