OPERATION
The following sections detail the operation of the TEMx28 Mapper.
BUS INTERFACE MODES
Each channel in the TEMx28 Mapper supports the following SONET/SDH bus modes of operation:
Drop Mode
In the drop mode of operation, TU/VTs from both the A and B buses are monitored, and a TU/VT is terminated
from either the A or B Drop bus to the receive output, without a return path in the transmit direction to the A and
B add buses.
Add Mode
In the add mode of operation, TU/VTs are monitored from the A or B Drop buses without a receive output, but
a path in the transmit direction for either A or B add buses is provided.
Single Unidirectional Ring Mode
In the single unidirectional ring mode of operation, a TU/VT is dropped from the A (or B) Drop bus, with the
return path the A (or B) Add bus. The other drop bus monitors the VT/TU. Timing for the TU/VT to be added to
the A (or B) Add bus is derived from either the A (or B) Drop bus, or from the A (or B) Add bus.
Multiplexer Mode
In the multiplexer mode of operation, a TU/VT is dropped from the A (or B) Drop bus, with the return path the B
(or A) Add bus. The other drop bus monitors the VT/TU. Timing for the TU/VT to be added to the A (or B) Add
bus is derived from either the A (or B) Drop bus, or from the A (or B) Add bus.
Dual Unidirectional Ring Mode
In the dual unidirectional ring mode of operation, a TU/VT is dropped from the A (or B) Drop bus, with the
return path both the A and B Add buses. The other drop bus monitors the VT/TU. Timing for the TU/VT to be
added to the A (or B) Add bus is derived from either the A (or B) Drop bus, or from the A (or B) Add bus.
