TOHINS[1]

Input

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

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.
