Function

RPOHFP

Output

170

The receive path overhead frame position

(RPOHFP) signal may be used to locate the

individual receive path overhead bits in the path

overhead data stream, RPOH. RPOHFP is logic

one while bit 1 (the most significant bit) of the path

trace byte (J1) is present in the RPOH stream.

RPOHFP is updated on the falling edge of

RPOHCLK.

RSDCLK

Output

156

The receive section DCC clock (RSDCLK) is a

192 kHz clock used to update the RSD output.

RSDCLK is generated by gapping a 216 kHz

clock.

RSD

Output

157

The receive section DCC (RSD) signal contains

the serial section data communications channel

(D1, D2, D3) extracted from the receive stream.

RSD is updated on the falling edge of RSDCLK.

RLDCLK

Output

158

The receive line DCC clock (RLDCLK) is a 576

kHz clock used to update the RLD output.

RLDCLK is generated by gapping a 2.16 MHz

clock.

RLD

Output

159

The receive line DCC (RLD) signal contains the

serial line data communications channel (D4 -

D12) extracted from the receive stream. RLD is

updated on the falling edge of RLDCLK.

ROWCLK

Output

155

The receive orderwire clock (ROWCLK) is a 64

kHz clock used to update the RSOW, RSUC, and

RLOW outputs. ROWCLK is generated by

gapping a 72 kHz clock.

RSOW

Output

163

The receive section orderwire (RSOW) signal

contains the section orderwire channel (E1)

extracted from the receive stream. RSOW is

updated on the falling edge of ROWCLK.
