Delayed activation is TL1 feature that facilitates command execution at pre-defined date/time

Need for delayed activation

It is common for NOC personnel to run large tasks during lean hours - E.g. Provisioning a thousand subscribers in a batch. The delayed activation feature allows operators to specify the date & time of execution of this task.  

How delayed activation works 

NEs store the TL1 commands (only those with delayed activation) in a message pending buffer. The agent executes these commands at the specified date/time (date/time is specified in each command). It also sends a response message on completion of the operation. 

Delayed activation parameters 

[ON=]  - ON represents the ORDER NUMBER. It is a numeric value assigned by you.  The NE to internally identify the delayed input message uses this number. 
[DATE=]  - DATE represents the exact date at which the delayed activation should occur. It takes the following format  <yy>- <mm > - <dd> 
[TIME=] - TIME represents the exact time at which the delayed activation should occur. It takes the following format:  <hh> - <mm> - <ss> 

How to set the delayed activation parameters in a TL1 command

Any TL1 command takes the following format:
<command code> <TID: AID: CTAG:general block> <payload block> .

You have to specify the three delayed activation parameters in the general block. 

Example:The following command ENT-CRS-STS1:TID:STS-3-2,STS-4-3:44:1, ,, : ; creates a cross connect between two channels, STS-3-2 and STS-4-3. To set the delayed activation parameters for this command, refer the table below
 

Delayed Activation at	Command
23:00 hrs same day	ENT-CRS-STS1:TID:STS-3-2,STS-4-3:44:210198, , 23-00-00, : ;
on dec 06, 2002	ENT-CRS-STS1:TID:STS-3-2,STS-4-3:44:210198,0212-06 , , : ;
23:00 hrs on dec06th2002	ENT-CRS-STS1:TID:STS-3-2,STS-4-3:44:210198,0212-06,23-00-00, : ;

where, 210198 indicates ORDER NUMBER, 23:00:00 indicates time, 0212-06 indicates date.

How to retrieve pending commands 

To retrieve the TL1 commands with delayed activation , which are stored in the NE, the following command can be used
RTRV-DA::[ALL|ORDNUM]:<ctag>::TTYPE ,TTIMEGE, TTIMELE;

The NE will retrieve all the pending delayed activation commands if you specify ALL in the retrieve message. To retrieve specific commands from the NE specify the ORDER NUMBER of those commands in the retrieve message. After retrieval of the commands, you can make necessary changes in that command and re-send if necessary. 

How to activate pending commands 

You can activate a pending command manually by sending a TL1 command. The command for activating the pending messages takes the following format.
ACT-DA::[ALL|ORDNUM]:<ctag>::;

By specifying ALL you activate all the pending commands. To activate specific pending commands, specify the exact ORDER NUMBER of the commands.
