250 User to 700 User System - 32 Compression Channels
250 user system (Release 3.0/3.1 chassis) upgrade to 700 user system with 32 channels of
compression.
This system uses the following existing modules:
• One RTC (3.0/3.1 133 MHz; 3.2/3.3 300 MHz)
• One E2T (3.0/3.1 133 MHz; 3.2/3.3 300 MHz)
• One Dual FIM Module
• One DSP Module (21061/21161) for telecom support
• One 64 Channel Echo Canceller
Add the following modules:
• One DSP Module (21061/21161) for telecom support
• One DSP Module (21161) for 32 compression channels
• One Dual FIM Module
• One 64 Channel Echo Canceller
Note: A second 64-channel Echo Canceller can be added, or the existing 64-channel
Echo Canceller can be replaced by a 128-channel Echo Canceller. If you choose to add
a second Echo Canceller, the controller must be operating on version 3.2 software. The
3.0/3.1 software does not support two 64 echo cancellers.
This provides:
• Eight DSP devices for telecom functions
• 32 channels of compression
• 30 Voice Mail Ports
• 128 channels of Echo Cancellation
• Four External FIM connections
• Four ASU connections (CIM ports)
The four external FIM connections are for providing connectivity for up to four Peripheral Units
or up to eight NSUs.
Note that there are two T1/E1 links per NSU.
To upgrade a 250 user system to a 700 user system with 32 channels of compression:
1. Remove the cover.
2. Install the new Dual FIM Modules (slot 2).
3. Install the new 21161 DSP Modules (slot 7 and slot 4).
4. Install the 64 Echo Canceller Module (slot 6).
