3. Application examples:
3.1. Traditional PCM application
The default factory status of RC3000 is without any configuration. All user-boards
support automatic recognition and voice channel allocation. In figure 1, the same
extension slots in the two devices use the same timeslots. In simple application, with
proper user-board the devices can start to work without any configuration. In this case
RC3000 does not use its function of cross connect and add/drop voice channel, this is
same as traditional single E1 PCM30 device that for point-to-point connection.
RC3000-2E1, RC3000-2E1 (ADM), RC3000-4E1, RC3000-OPT all can be used in this
way.
3.2. Automatic ADM application
RC3000-2E1 (ADM) has the ADM function, and figure 2 is a typical application:
