- The
TN790B is very similar to the TN790. The circuit pack is
designed to handle errors that are associated with the EM-BUS
and is required for use of the C-LAN (TN799) and NetPkt (TN794)
circuit packs in R7 and later.
- Circuit
packet level replacement for the TN786B/CPP1 combination
- Does
not support a mezzanine board for memory expansion (no CPP1 circuit
pack is used)
- Provides
a performance increase over the TN 786B/CPP1 combination
- RISC
processor at 40 MHZ includes all of the functions of the TN786B
processor as well as providing an operating system base more common
with R7r
- Diagnostics
for the TN790 are enhanced over earlier systems
- Compatible
with the processor interface circuit pack (TN765), the PACCON
circuit pack (TN778), the NETCON circuit pack (TN777B), and the
duplication interface circuit pack (TN772)
