Remote Office 9150 description

Optional DSP application modules

DSPs convert voice and fax into digital data for transport over the IP and

PSTNs. Initially, the Remote Office 9150 unit ships with the ability to support

up to eight simultaneous calls through a DSP that is built into the Remote Office

9150 unit's motherboard. To add support for up to 32 simultaneous calls, you

must install DSP application modules. Up to three DSP application modules are

supported. Each module provides up to eight more simultaneous calls.

In addition, you can configure the Remote Office 9150 unit for blocking with

only enough modules to support the maximum number of simultaneous calls.

For example, a Remote Office 9150 unit that is equipped with a single DSP

application module supports 16 simultaneous calls, for a ratio of 2:1 blocking.

For more details, see "Planning for future growth" on page 79.
