NOTE

The TRDDS-R must be used with an appropriate Total Reach dataport unit.

1. GENERAL

This practice provides installation and maintenance procedures for the ADTRAN TRDDS-R Total Reach¨ All Rate DDS Termination Unit. Figure 1 is an illustration of the ADTRAN TRDDS-R Unit.

The ADTRAN TRDDS-R is a span-powered termination unit designed to deliver data rates up to 64 kbps and provide testing functionality. Used in combination with a Total Reach dataport unit, the TRDDS-R converts the two-wire Total Reach signal to the traditional four-wire DDS signal for presentation to the customer.

The TRDDS-R is an auto-rate adaptive digital network interface typically located at the customer premises point-of- demarcation. The TRDDS-R will deliver a standard four- wire DDS signal up to 18 kft beyond the TRDDS-R. Both customer and network interfaces are equipped with outside plant lightning protection. The customer interface is capable of receiving signals attenuated to -45dB at the Nyquist frequency of four-wire AMI DDS. In addition to terminating the two-wire extended range signal, the TRDDS- R functions as a regenerative loopback device supporting Telco-generated testing. The TRDDS-R unit is available in T200 mechanics, and may be optioned for 0 or Ð10 dB output toward the customer. Figure 2 illustrates the Total Reach DDS Circuit Diagram.
