Sample Configuration

Multipoint

Figure G-2 shows a sample configuration for multipoint applications.

TMp control modems can accept mixed inbound rates from tributary modems. For example, one inbound link may be configured for 14.4 kbps while another link experiencing line impairments may be configured for 9.6 kbps. The following control/tributary rate combinations are allowed: control at 19.2 kbps, tributaries at 14.4 or 9.6 kbps; control at 14.4 kbps, tributaries at 14.4 or 9.6 kbps; control at 9.6 kbps, tributaries at 9.6 or 7.2 kbps; control at 7.2 kbps, tributaries at 7.2 or 4.8 kbps; control at 4.8 kbps, tributaries at 4.8 or 2.4 kbps; control at 2.4 kbps, tributaries at 2.4 kbps. Tributary rates will never exceed control rates. If tributary and control rates are equal, reducing the control rate will automatically reduce the tributary rate.
