Transmit PLCP Overhead Data

(TPOH[4:1]). TPOH[4:1] is valid when the

FRMRONLY bit in the S/UNI-QJET

Configuration 1 registers is logic 0.

TPOH[4:1] contains the PLCP path

overhead octets (Zn, F1, B1, G1, M1, M2,

and C1) which may be inserted in the

transmit PLCP frame. The octet data on

TPOH[4:1] is shifted in order from the

most significant bit (bit 1) to the least

significant bit (bit 8). TPOH[4:1] is

sampled on the rising edge of

TPOHCLK[4:1].

Framer Transmit Data (TDATI[4:1]).

TDATI[4:1] contains the serial data to be

transmitted when the S/UNI-QJET is

configured as a DS3, E3, or J2 framer

device for non-ATM applications by setting

the FRMRONLY bit in the S/UNI-QJET

Configuration 1 Register. TDATI[4:1] is

sampled on the rising edge of TICLK[4:1] if

the TXGAPEN register bit in the

S/UNI-QJET Configuration 2 register is

logic 0. If TXGAPEN is logic 1, then

TDATI[4:1] is sampled on the falling edge

of TGAPCLK[4:1].

Transmit Path Overhead Frame Position

(TPOHFP[4:1]). TPOHFP[4:1] is valid

when the FRMRONLY bit in the

S/UNI-QJET Configuration 1 Registers is

logic 0. The TPOHFP[4:1] output locates

the individual PLCP path overhead bits in

the transmit overhead data stream,

TPOH[4:1]. TPOHFP[4:1] is logic 1 while

bit 1 (the most significant bit) of the path

user channel octet (F1) is present in the

TPOH[4:1] stream. TPOHFP[4:1] is

updated on the falling edge of

TPOHCLK[4:1].
