Product description

The merchandise described in your letter and attached literature are certain printed circuit assemblies for the Universal Modular Carrier (UMC) System 1000E. The UMC 1000E is a Digital Loop Carrier System designed to provide telephone subscriber services. This request covers five printed circuit assemblies: CPU - The Central processing Unit provides overall control of the UMC at both the LET (Local Exchange Terminal) and the RST (Remote Subscriber Terminal) nodes. The CPU controls call processing for the UMC system. It allocates time slots for subscriber who have gone off-hook, cancels time slots for terminated calls, relays provisioning information to and from subscriber interfaces and provides automatic concentration during span failures. mCPU - The Mini Central Processing Unit provides overall control of the UMC 1000 at the RST nodes. It controls call processing for the UMC 1000 system and its functioning is similar to the CPU described above. LPU - The Local Power Unit is the local AC power unit for a Remote Subscriber Cabinet. It provided -48 VDC rectification, charging up for backup batteries, and surge protection. mRPSU - The Mini Remote Power Supply Unit converts the -48 VDC local exchange battery input into + -5V, -32V, -52V and ring voltage required by the common central equipment and line cords located at the UMC 1000 RST. ADP - The AC Disconnect Panel is used with the Local Power Unit. It serves as an AC interconnect point for service entrance, battery heater thermostat and two pad connects with a dedicated breaker, and an AC interconnect to the LPU board.

CBP rationale

The applicable subheading for the CPU and mCPU printed circuit assemblies will be 8517.90.3600, Harmonized Tariff Schedule of the United States Annotated (HTSUSA), which provides for “Printed circuit assemblies: for telephonic apparatus: For switching or terminal apparatus (other than telephone sets). The applicable subheading for the LPU and mRPSU printed circuit assemblies, will be 8504.40.8500, Harmonized Tariff Schedule of the United States Annotated (HTSUSA), which provides for “Static convertors: For telecommunications apparatus. The applicable subheading for the ADP circuit assemblies, will be 8537.10.9070, Harmonized Tariff Schedule of the United States Annotated (HTSUSA), which provides for “Boards.
