10.33. Hotline/Off-Hook Recall

The hotline feature automatically sets up VOICE and DTE connections immediately via initial seizure to a preset destination assigned in the HOTLN AMO.

Assign memory
```
ADD-DIMSU:TYPE=USER,HOTDEST=<number>;
```

Assign a hotline destination

ADD-HOTLN:TYPE=HOTDEST,HTLNIDX=<number>,
DEST=<number>;

Activate the feature:
```
CHA-FEASU:TYPE=A,CM=HOTRCL;
```

Assign the hotline destination to a station

CHA-SDAT:STNO=<number>,TYPE=DATA1,
HOTIDX=<number>;

Assign the attribute HOT for service voice to a station by either assigning it switchable to a COS of the station (toggling between a COS with attribute HOT and one without HOT is possible - COS1/COS2 of the station):
```
CHA-COSSU:TYPE=COS,COS=<number>,
AVCE=HOT; (for VOICE)
```
or assigning it fixed (COS with AVCE=HOT is not necessary in that case):
```
CHA-SDAT:STNO=<number>,TYPE=ATTRIBUT,AATTR=HOT;
```
Assign the attribute HOT for service DTE to a COS of the station (toggling between a COS with attribute OFHKRC and one without OFHKRC):
```
CHA-COSSU:TYPE=COS,COS=<number>,ADTE=HOT; 
```
The off-hook recall feature automatically sets up a connection to a preset destination assigned in the HOTLN AMO if either no digits are dialled, or only an incomplete digit sequence is dialled within a preset time. For AnaTe stations, the connection is also set up after time-out of busy tone from A-B disconnection of one party or after time-out of busy tone after dialing an Out of Service destination. This feature is provided for the VOICE service only.
Assign memory
```
ADD-DIMSU:TYPE=USER,HOTDEST=<number>;
```

Assign an off-hook recall destination

ADD-HOTLN:TYPE=OFRCDEST,HTLNIDX=<number>,
DEST=<number>;

Activate the feature:
```
CHA-FEASU:TYPE=A,CM=HOTRCL;
```
Change the time for automatic connection setup in AMO DTIM2:
Digital phones:

CHA-DTIM2:TYPEDH=GEN,ANATN1=10; 10 seconds is default value.

Analog phones:

CHA-DTIM2:TYPEDH=GEN,DTNT1=10; 10 seconds is default value

IMPORTANT:

The parameter ANATN1 or DTNT1 is also used to configure the dial supervision time (i.e. the maximum time allowed between lifting the handset and dialing a number). If the maximum time allowed is exceeded, "Timeout" appears on the display.

Assign the off-hook recall destination to a station

CHA-SDAT:STNO=<number>,TYPE=DATA1,
HOTIDX=<number>;

Assign the attribute OFHKRC to a station by either assigning it switchable to a COS of the station (toggling between a COS with attribute OFHKRC and one without OFHKRC is possible - COS1/COS2 of the station):
```
CHA-COSSU:TYPE=COS,COS=<number>,
AVCE=OFHKRC;
```
or assigning it fixed (COS with AVCE=OFHKRC is not necessary in that case):
```
CHA-SDAT:STNO=<number>,TYPE=ATTRIBUT,
AATTR=OFHKRC;
```
