Description
The TR OCU DP can interoperate over the carrier system with another TR OCU DP, DS0 DP,
TR DDS-DP, 1/0 DCS, or switch. The TR OCU DP can be located in an end office, hub office,
intermediate office, or Digital Loop Carrier (refer to

Figure 2. Total Reach DDS Circuit Diagram
The TR OCU DP occupies a single channel position in a WECO ® -compatible D4 channel bank,
AT&T ® SLC-96 terminal, or an ADTRAN ACT 1900/2300 channel bank, providing 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 TR OCU DP span-powers the remote TR DDS-R located at the customer premises. The TR
DDS-R converts the 2-wire signal to the traditional 4-wire Alternate Mark Inversion (AMI)
signal for transmission to the customer.
