CTE in RPC Mode (SDV)
As shown in
, the Encryption and Edge QAM pieces are
nominally separated in the SDV architecture. Therefore, as demonstrated in the
preceding graphic, the Network Encryptor is positioned to perform the encryption.
The APEX1000 receives already encrypted SPTSs at its input, and routes them to the
appropriate output according to the RPC control. This encryption procedure may also be
performed at the edge level through the APEX1000 using CTE.
