Description
ADTRAN Total Reach DDS HECI D4OIKW98AA
The ADTRAN Total Reach OCU-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 Total Reach DDS-DP unit, the Total Reach OCU-R converts the 2-wire Total Reach signal to the traditional 4-wire DDS signal for presentation to the customer. The Total Reach OCU-R is an auto-rate adaptive digital network interface located at the customer premises point of demarcation. The OCU-R will deliver a standard four-wire signal up to 18 kft beyond the OCU-R. Both customer and network interfaces are equipped with outside plant lightning protection. The customer interface is capable of receiving signals attenuated to –45 dB at the NyQuist frequency of four-wire AMI DDS. In addition to terminating the 2-wire extended range signal, the Total Reach OCU-R functions as a regenerative loopback device supporting Telco generated testing. The Total Reach OCU-R unit is available in T200 mechanics, and may be optioned for 0 dB or -10 dB output toward the customer. Features:
- Two-wire deployment
