QPC551 Radio Paging Trunk card
Signal duration on the 18-pair faceplate
Binary value (.1 second)
Note: This switch determines the length of time a signal stays on the 18-pair data bus. The time
is set in binary to the nearest tenth second. For example, to keep data on the bus for 5 seconds,
the switch settings total 50 by closing S1.2, S1.5, and S1.6.
Signal duration and pause time
Binary value (.1 second)
Note: This switch determines the time data must stay on the 18-pair data bus plus the pause
time between the removal of data and the reappearance of subsequent data. The time is set in
binary to the nearest tenth second. For example, to keep data on the bus for 5 seconds and have
a pause time of 3.2 seconds, the switch settings should total 82 by closing S2.2, S2.5, and S2.7.
