Hi Kent:

The schematic for the MK-456A retransmission cable CX-4656 is on page 59 of 112
in TM 11-5820-398-12.pdf that is online at ETM/LOGSTA.  The MK-456A includes a
capability for inserting a handset in the center of the cable to both monitor
and send messages and this adds some complication.  There is also a lot of EMI
suppression by means of chokes and caps.
A-><- A = ground
B -> D (with some attenuation)
C <- E
D <- B (with some attenuation)
E -> C

73,
