Table 2.3.8-1 Call Proc I/O connector and signal assignment
Pin Signal Name Function
1 BER_DAT_IN Data input for BER measurement. Inputs da-
ta where the test terminal is demodulated at
TTL or CMOS level.
2 BER_DAT_OUT Outputs demodulation data at CMOS level.
3 DSUB15_RSV1 Reserved
4 DSUB15_RSV4 Reserved
5 (NC) Not connected
6 FRAME_TRG_
OUT The trigger signal output at frame cycle. It
outputs at CMOS level.
7 BER_CLK_IN Clock signal for BER measurement. Inputs
data clock where test terminal is demodulated
at TTL or CMOS level.
8 BER_CLK_OUT Outputs demodulation data clock at CMOS
level.
9 (NC) Not connected
10 (NC) Not connected
11 SYNC IN Inputs the synchronized signal from the master
side at LVCMOS level when two MD8470A
units are synchronous operated.
12 SYNC OUT
Outputs the synchronizing signal to the slave
side at LVCMOS level when two MD8470A
units are synchronized.
13 GND Grounding
14 DSUB15_RSV3 Reserved
15 (NC) Not connected
In addition, the MN8110B I/O adapter (sold separately) is provided as an
applicable part for these call processing ports.
The MN8110B is a unit that converts from a 15-pin Mini D-Sub connector
to a BNC connector. The input/output signal for the Call Proc Timing I/O
connector of the MD8470A can be input and output from the MN8110B
BNC connector by connecting the Call Proc I/O connector (15-pin Mini D-
Sub) on the MN8110B rear panel to the
Call Proc Timing I/O
connector of
the MD8470A using the connection cable supplied with the MN8110B.
