Section 13.1.2. Announcement Unit for Greeting Text and General Text

13.1.2. Announcement Unit for Greeting Text and General Text

If announcements are required for incoming CO trunk calls as well, 2 announcement units must be connected: one unit for the company greeting, and the second one for the announcement. To make sure that a line to the unit with the announcement text is free after the greeting, 2 trunk groups are assigned for the announcement unit: one group which is seized only internally and one group which is seized externally after the greeting text. The code for external and internal seizure is the same, but it leads to different digit analysis results in the dial plan for different CPSs.

Assign an announcement unit for greeting text

Assign a TMOM module

AD-BCSU:MTYPE=PER,LTU=number,SLOT=number,
PARTNO=string;

Assign identical code for greeting and announcement text

AD-WABE:CD=key-num,DAR=ANSCO; 

AD-WABE:CD=key-num,DAR=ANSINT;

Add class of trunk
```
AD-COT:PAR=NTON; 
```
Add class of parameter
```
AD-COP:PAR=SACK&LSUP;  
```
Add trunk group
```
AD-BUEND:NO=number; 
```

Add trunk circuit

AD-TSCSU:COTNO=number,DEV=ANS,COPNO=number; 

EINR-TSCSU:COTNR=number,BUNR=number,GER=ANSEA,
COPNR=number,SUPV=SUPV2,ACKT=SZACK2;

Assign a route for the greeting text unit. The CPSs must be specified, since the code leads to different digit analysis results in the DPLN.
```
AD-RICHT:TYPE=CD,CD=key-num,CPS=6,SVC=VCE,
TGRP1=number,CPAR=ANN; 
```
Set timers (seconds)
```
CHA-DTIM1:TYPEDH=TCOM,RASTA= *1),RECAMDLY= *2.; 
```
*1. Set time for text length in seconds (must be longer than the greeting text).

*2. Time for waiting for start of greeting text in seconds (must be approximately as long as the greeting text). A ringing tone is sent until the text begins. If the timer expires before zero passage, i.e. the set time is too short, the connection is released.

Assign an announcement unit for announcement text (after greeting text)

The configuration data, class of trunk and class of line parameters are assigned as for the greeting text unit.

Assign two trunk groups

AD-BUEND:TGRP=zz,NO=number; 

AD-BUEND:TGRP=yy,NO=number;

Assign the trunk circuits (as many as required)

AD-TSCSU:NO=number,COTNO=number,TGRP=number,
DEV=RA,COPNO=number,SUPV=SUPV2,ACKT=SZACK2;

Assign a route to the announcement unit
The trunks are assigned to the two trunk groups. The CPS values must be specified as follows.
```
AD-RICHT:TYPE=CD,CD=key-num,CPS=5&8&9,SVC=VCE,
TGRP1=zz,CPAR=RATGRP,TGRP2=yy ,CPAR=NONE; 
(CPS 10&11&12 are only for tie-traffic.)
```
Set timers (seconds)
```
CHA-DTIM1:TYPEDH=TCOM,RATX= *.; 
```
*) The time must be set so that it is twice as long as the announcement text. If several announcement units are used, the longest text must be used as a reference.
