Transmit DS3/E3/J2 Overhead Insertion
(TOHINS[4:1]). TOHINS[4:1] controls the
insertion of the DS3, E3, or J2 overhead
bits from the TOH[4:1] input. When
TOHINS[4:1] is high, the associated
overhead bit in the TOH[4:1] stream is
inserted in the transmitted DS3, E3, or J2
frame. When TOHINS[4:1] is low, the DS3,
E3, or J2 overhead bit is generated and
inserted internally. TOHINS[4:1] is
sampled on the rising edge of
K2
M4
R1
TOHCLK[4:1]. If TOHINS[4:1] is a logic 1,
the TOH[4:1] input has precedence over
the internal datalink transmitter, or any
internal register bit setting.
