SONET/SDH TRANSPORT OVERHEAD TRANSCEIVER
Pin Name Pin Type Pin Function
No.
TOWCLK Output
3
The transmit order wire clock (TOWCLK) is a
64 kHz clock used to sample the TSOW, TSUC,
and TLOW inputs. TOWCLK is generated by
gapping a 72 kHz clock.
TSOW
Input
5
The transmit section order wire (TSOW) signal
contains the section order wire channel (E1)
inserted into the outgoing stream. The
TTOHEN input takes precedence over TSOW.
TSOW is sampled on the rising edge of
TOWCLK.
TSUC
Input
4
The transmit section user channel (TSUC)
signal contains the section user channel (F1)
inserted into the outgoing stream. The
TTOHEN input takes precedence over TSUC.
TSUC is sampled on the rising edge of
TOWCLK.
TLOW
Input
TLDCLK Output
TLD
Input
TAPSCLK Output
160 The transmit line order wire (TLOW) signal
contains the line order wire channel (E2)
inserted into the outgoing stream. The
TTOHEN input takes precedence over TLOW.
TLOW is updated on the rising edge of
TOWCLK.
1
The transmit line DCC clock (TLDCLK) is a 576
kHz clock used to sample the TLD input.
TLDCLK is generated by gapping a 2.16 MHz
clock.
2
The transmit line DCC (TLD) signal contains
the line data communications channel (D4 -
D12) inserted into the outgoing stream. The
TTOHEN input takes precedence over TLD.
TLD is sampled on the rising edge of TLDCLK.
157 The transmit automatic protection switch
channel clock (TAPSCLK) is a 128 kHz clock
used to sample the TAPS input. TAPSCLK is
generated by gapping a 144 kHz clock.
