Planning for Remote Gateway 9150 unit installation Standard 3.1
Planning for future growth
The Remote Gateway 9150 unit can change or grow along with your
telecommunication needs. This section describes planning for accommodating
those needs.
Adding DSP modules
The Remote Gateway 9150 unit ships with the ability to support up to 32
stations (you must assign all 32 to the same RLC). A Remote Gateway 9150 unit
supports up to eight simultaneous voice calls when over the IP network.
You can increase the voice processing capability of the Remote Gateway 9150
unit by installing up to three more DSP modules. Each DSP module adds
support for up to eight more simultaneous calls (to a maximum of 32).
To determine how many DSP application modules you need to install, use the
“Remote Gateway 9150 System expansion worksheet” on page 385. For
instructions on installing additional DSP modules, refer to “Installing trunk
interface or DSP application modules” on page 93.
Refer to “DSP configuration” on page 239 for configuration information.
Note: When installing additional DSP modules on the Remote Gateway 9150
unit, you must also increase voice processing capability on the RLC. The
number of modules that need to be added on the RLC depend on the
requirements of other remote units connecting to the same RLC. If only this
Remote Gateway 9150 unit is connecting to the RLC, then the same number of
DSP modules must be installed on both the Remote Gateway 9150 unit and the
RLC. To calculate the RLC’s DSP refer to the expansion worksheet in the Reach
Line Card Installation and Administration Guide (NTP 555-8421-210).
