5.5.7 Ring Number

The DAI-2 may need higher ring sensitivity if it is used with a UHF radio telephone (sometimes called a "ranch
phone"), a cellular-to-RJ11 adapter, or another device which generates a square wave ring signal. However, in
installations where there is a significant amount of "hum" on the telephone line, the ring sensitivity may need to be
lowered. This prevents the DAI-2 from interpreting the hum as a continuous ring. Ring sensitivity is programmed at
address 348.
When ring sensitivity is 0 the DAI-2 does not answer the telephone.
Value Ring Sensitivity
0 Does not answer
1 Least sensitive
2 Less sensitive
... (factory setting 5)
8 More sensitive
9 Most sensitive
+ Values above 9 default to 9
The DAI-2 normally detects when a telephone connection is cut off prematurely--before the hang-up command has
been given. This may occur if the telephone line “goes dead” or the operator hangs up the calling phone by accident.
While the pulse hang-up detection can be disabled by programming at address 360, it is recommended that you
carefully consider the possible consequences before changing this programming.
Value Pulse hang-up detection
0 Enabled--system will drop line automatically
1 Disabled--system will remain on-line if connection is dropped
+ Values above 1 default to 1
