Central Site of a Multi-site Configuration
8-2
Issue 1 January 1997
Overview
In a multi-site configuration, the Central Site performs the collection and processing of
SMDR from every site it includes.
SMDR is handled at each site by either a direct connection from the site’s MERLIN
LEGEND communications system into the Central Site’s PC, or indirectly, from another
PC running MERLIN LEGEND Reporter or from a PSU (these “call collectors”
themselves receive SMDR directly from the site’s MERLIN LEGEND communications
system).
The figure below illustrates how this works.

1.
As a phone call is placed or received at a site, it is routed through the MERLIN
LEGEND communications system to its final destination.
2.
The communications system prepares an electronic record of the transaction. If it is
on a remote site, its “call collector” — a PSU or another PC — saves the output until
the Central Site can retrieve it.
3.
At the Central Site, all remote sites have been added to its database. At this point,
the Call Collection Interface for each individual site regulates its own polling
schedule, then starts the actual transmission, and finally translates the call records.
4.
The call records from each site are processed according to each site’s databases,
then they are stored under individual site directories.
5.
At report time, the Central Site selects which sites it wants to include in reports, then
runs the reports.
