STo7
Power Supply Ground
. Nominally 0 volts.
2
Positive Power Supply.
Nominally 5 volts.
3
Serial, 32 Channel, 2.048 Mb/s Link 7 (Output Type 3)
. Only channels 9 - 31 are
available for user data transfer (1.474 Mb/s). Channels 0 - 8 (0.576 Mb/s) are reserved
for access to fiber overhead information. Output is active only when the receiver
detects the synchronization pattern on RxDATA input stream; output is high impedance
during loss of synchronization.
4
DOUT8K0
Asynchronous 8 kHz Signal 0 (Output Type 3).
Sourced from the far-end DIN8K0
input.
5
DOUT8K1
Asynchronous 8 kHz Signal 1 (Output Type 3).
Sourced from the far-end DIN8K1
input.
6
C20o
20.48 MHz Clock (Output Type 3).
Derived from transmit PLL 40.96 MHz clock divided
by 2 (see pin 18). Made available for system use.
7
NC
No Internal Connection.
8
FBADDR7
Frame Buffer RAM Address Bit 7 (Output Type 2).
9
STo6A
Serial, 32 Channel, 2.048 Mb/s Link 6A (Output Type 3).
Output is active only when
the receiver detects the synchronization pattern on RxDATA input stream; output is high
impedance during loss of synchronization.
