Functional Description of the UMT-C-KV
The interface between the EMTR-3-KV and the UMT-C-KV is an Inter-Integrated
Circuit (I
2
C) physical layer over which the Common Data Layer communications
format operates. The UMT-C-KV performs the gateway function of connecting the
EMTR-3-KV to the TWACS network. TWACS is able to read and write registers
as well as execute Opcodes on the EMTR-3-KV using gateway functionality. The
UMT-C-KV maintains a status indication of the EMTR-3-KV interface as well as
a summary of EMTR-3-KV reported failures. The EMTR-3-KV is optional and
may not be present on all UMT-C-KV units.
