Signal name Pin # Type(I/O) Signal description
TX_E1_DATA 126 I TRANSMIT E1 DATA: Local orderwire channel data byte
(E1) to be inserted by the HDMP-3001 into the outgoing
SONET data stream.
TX_E2_DATA 127 I TRANSMIT E2 DATA: Express orderwire channel data byte
(E2) to be inserted by the HDMP-3001 into the outgoing
SONET data stream.
TX_F1_DATA 128 I TRANSMIT F1 DATA: Maintenance channel data byte (F1)
to be inserted by the HDMP-3001 into the outgoing SONET
data stream.
TX_E1E2F1_CLK 129 O TRANSMIT E1/E2/F1 DATA REFERENCE CLOCK: A 64 kHz clock
reference output for E1/E2/F1 data to be inserted by the
HDMP-3001 into the outgoing SONET data stream.
TX_LDCC_DATA 123 I TRANSMIT LINE DCC DATA: Input for the Line Data
Communications Channel (DCC) to be inserted by the HDMP-3001
into the outgoing SONET data stream.
TX_LDCC_CLK 124 O TRANSMIT LINE DCC REFERENCE CLOCK: A 576 kHz clock
reference for Line DCC data to be inserted by the
HDMP-3001 into the outgoing SONET data stream. The
TX_LDCC_DATA inputs are sampled on the falling edge of
TX_LDCC_CLK.
TX_SDCC_DATA 117 I TRANSMIT SECTION DCC DATA: Input for the Section
Data Communications Channel (DCC) to be inserted into the
outgoing SONET data stream from the HDMP-3001.
TX_SDCC_CLK 118 O TRANSMIT SECTION DCC REFERENCE CLOCK:
A 192 kHz clock reference for Section DCC data to be inserted
by the HDMP-3001 into the outgoing SONET data stream. The
TX_SDCC_DATA inputs are sampled on the falling edge of
TX_LDCC_CLK.
TX_8K_CLK 132 O 8kHz TRANSMIT CLOCK: A general purpose 8kHz
buffered clock derived from TX_SONETCLK which may be
used for external clock reference purposes.
