BSR status poll vector

Last Updated : Jan 31, 2013 |

To collect information from the remote server, the consider location 2 adjust-by 30 command in the primary vector places an ISDN call, known as a status poll, to the status poll vector on the server at location 2. The following example shows a status poll vector on the remote server used for the purpose.

BSR example of status poll vector on remote Communication Manager

1. consider split  2    pri m   adjust-by 0
2. consider split 11    pri m   adjust-by 0
3. reply-best

The status poll retrieves and returns information to the origin server. The call is not connected to the status poll VDN.

The vector compares splits 2 and 11, identifies the best split and sends the information back to server 1 with the reply-best command. Note that the adjust-by command can be used on the remote server to adjust the EWT returned by either of the splits. When EWT adjustments are applied at both the origin and remote servers, the two adjustments are added at the origin server.

The consider command is ISDN neutral and does not return answer supervision. The status poll call drops after vector processing executes the reply-best step, but the ISDN DISCONNECT message returned to server 1 contains the information from the best split considered at location 2. Once the remote server returns the necessary information, the consider series in the primary vector on server 1 can continue at the next vector step.

Caution:

Do not use the status poll vectors to poll other servers. Status poll vectors compare resources only on the server where the vector resides. Status poll vectors must always end with a reply-best command. Do not use a busy or disconnect command.

Note:

Multisite BSR includes mechanisms that automatically limit the number of status poll calls that can be placed over the network when such calls are unlikely to yield better service for the caller.
