11.8.2 Receive DCC Port Interface
RSOH_DCC_Select
The index indicates the port, one per transmit line. The Transmit DCC Clocks DCCTXCLK1..4
have a constant frequency and depend on the configured mode, as indicated in following
table:
Note: Configuration of the Transmit DCC Port interface is done in the memory map of the
TOH Generator (see
DCC_Port_Enable setting. If the Transmit DCC Port is disabled, the Transmit Port Clock
DCCTXCLK output will be held low.
The Receive DCC ports are constant bit-rate ports that provide either the received RS DCC
bytes or the received MS from the incoming STM-4 or the four STM-1 frames. In STM-4
mode, only the first DCC Port is active.
Each Receive DCC port can be configured for RS DCC bytes or MS DCC bytes:
The Receive DCC Port consists of following leads:
The index indicates the port, one per receive line. The Receive DCC Clocks DCCRXCLK1..4
have a constant frequency and depend on the configured mode, as indicated in following
table:
Note: Configuration of the Receive DCC Port interface is done in the memory map of the
TOH and DCC Port (see
DCC_Port_Enable setting. If the Receive DCC Port is disabled, the Receive Port Clock
DCCRXCLK output will be held low.
