The Transmit Connect Select registers control the source of transmit path for each channel.
TSEL[4:0]:
PROCM:
TXEN:
Channel #0 to #7 Transmit Connect Select
The transmit cross connect select (TSEL[4:0]) determines the source of transmit path for
the channel. When TXEN is low, the TSEL[4:0] is ignored. When TXEN is high,
TSEL[4:0] specifies the source channel for the Transmit Path Processor (TPOP) of the
channel. TSEL[4:0] equal to 0 to 7 specify the channels in the S/UNI-8x155. TSEL[4:0]
equal to 16 to 23 specify the receive APS links (bridge function). Note that TSEL[4:0]
values 8 to 15 and 24 to 31 are unused channels and are not supported.
The transmit APS protection mode select (PROCM) configures the channel for protection or
working operation. When PROCM is set low, the channel’s receive path is sent over the
transmit APS link (channel is operating as a protection link). When PROCM is set high, the
channel’s transmit path is set over the transmit APS link (channel path is being bridged to
another channel).
The transmit cross connect enable (TXEN) controls when a channel’s Transmit Path
Processor (TPOP) can cross connect with another channel’s path. When TXEN is low, the
channel operates normally. When TXEN is high, the channel cross connect is enabled.
