The Receive Connect Select registers controls the source of receive path for each channel.
RSEL[4:0]:
RXEN:
Channel #0 to #7 Receive Connect Select
The receive cross connect select (RSEL[4:0]) determines the source of receive path for the
channel. When RXEN is low, the RSEL[4:0] is ignored. When RXEN is high, RSEL[4:0]
specifies the source channel for the Receive Path Processor (RPOP) of the channel.
RSEL[4:0] equal to 0 to 7 specify the channels in the S/UNI-8x155. RSEL[4:0] equal to 16
to 23 specify the receive APS links (protect function). Note that RSEL[4:0] values 8 to 15
and 24 to 31 are unused channels and are not supported.
The receive cross connect enable (RXEN) controls when a channel’s Receive Path
Processor (RPOP) can cross connect with another channel’s path. When RXEN is low, the
channel operates normally. When RXEN is high, the channel cross connect is enabled.
