1220010L2 (ADTRAN)

ADTRAN offers a UBR1TE-V product that may be deployed in the adjacent to customer position to provide transport for DDS/Frame Relay services with an ADTRAN IDSL-OCO-R. This allows pair savings over traditional DDS deployment on local loops up to 18kft of mixed gauge wire. The IDSL OCU-R is used to terminate the U-interface at the customer's premises provided by the UBR1TE V and to convert the 2 wire ISDN signal to a 4 wire AMI DDS signal for presentation to the customer. Together, the UBR1TE V and IDSL OCU-R allow testing over the ISDN transport network to be performed with traditional DDS methods. In this mode UBR1TE V's may be placed in tandem and function as DSO DP's while the IDSL OCU-R functions as an OCU.
