250 User System - Add 64 Compression Channels
250 user system (Release 3.0/3.1 chassis) upgrade to add support for 64 compression channels
requires a new Release 3.2 chassis.
The 250 user, 64 compression channel upgrade package includes:
• One 300 MHz RTC
• One 300 MHz E2T
• One 64 Channel Echo Canceller
• One Dual FIM
• One DSP Module (21061/21161) for telecom support
Add the following modules:
• Two DSP Modules (21161) for 64 compression channels
This provides:
• Four DSP devices (21061/21161) for telecom functions for up to 250 users
• Eight DSP devices (21161) for 64 channels of compression
Note: Some controllers in release 3.0 had the DSP installed in Slot 6. This DSP should
be moved to Slot 8 before installing the compression DSP in Slot 3.
Note: Retain your System ID Module and Hard Drive.
Note: You must purchase compression licenses. Refer to E2T Compression for
guidelines on meeting your compression requirements.
