Scenario 1: Small Single Site

The diagram below illustrates some of the connection possibilites for a small, single-site setup. The configuration shown below could typically handle up to 5 simultaneous calls on a single ADSL Max line, or 12 simultaneous calls on a single ADSL2+ line (less if sharing the bandwidth with other applications and dependent on the distance to the local exchange).

In this scenario an existing broadband line is used to carry the voice traffic.

Phones can be a mix of hardware IP phones and/or software phones running on a PC. Legacy analogue phones can also connect via an ATA.

A wireless laptop can also be used where no existing telephone or data wiring exists e.g. warehouses, garages, temporary offices etc.

Organisations adopting this configuration can consolidate all their voice and data traffic on to a single ADSL line. Any other dedicated telephone lines in use can be retired to achieve a significant cost saving. The analogue line supplying the ADSL can be used as a traditional fax line, or as a backup should the Internet connection go down.
