Notes on Figure 48:
1. The cross-wiring between the two punchdown blocks is not as straight-forward as Figure 48 may suggest. Wiring
is dependent on the telco line types and the system application.
2. In the Transmitter Key Type database set:
M68 = “On”
3. In the Transmitter Key Up Control database set:
RqstSgnlPlrty = “high”
Be sure to consult Table 12 before making a cable or cross-wiring the punchdown blocks. Also
refer to the
Model 68 Transmitter System Controller Operating and Installation Manual (Part
No. 025-9089) for details on connecting the unit to other radio station equipment.
