Revision History
This document has been revised to incorporate the
response to the loopback pushbutton function of the
DDS-R ACE remote unit, and add reference to false
latching loopback prevention at 64 kbps.
Description
The ADTRAN Series 5 Total Reach DDS-DP is a
functional replacement for the SLC
®
Series 5 OCU
DP, CLEI 5SCU48, delivering data at rates up to 64
kbps using a single copper pair. Used in combination
with the DDS-R termination unit, the Series 5

DDS-DP can accommodate extended loop lengths,
eliminating the need for DDS repeaters. The Series 5
DDS-DP span powers the DDS-R located at the
customer premises. The DDS-R converts the 2-wire
signal to the traditional 4-wire Alternate Mark
Inversion (AMI) signal for presentation to the
customer.
The DDS-DP occupies a single channel position in the
AT&T
®
SLC Series 5 or Series 5 compatible channel
bank. It provides the interface between a DS0 time
slot of the T-carrier data stream and the 2-wire
metallic loop extending to the customer premises. The
Series 5 Total Reach DDS-DP will interoperate over
the carrier system with another DDS-DP, OCU DP,
DS0 DP, 1/0 DCS, or switch and can be located in an
end office, hub office, intermediate office, or Digital
Loop Carrier (
Figure 2
). The 2-wire loop is
connected using the odd pair Tip (pin 31) and Ring
(pin 32) on the Series 5 backplane.
NOTE
The Series 5 Total Reach DDS-DP must be used
with an appropriate DDS-R unit.
