Earlier versions of the 8900 Audio TX/TF/TFN frames have a backplane
configuration as shown in Figure 22. The earlier frames differ from the
current frames in one main area:
• There is no network configuration (IP address) storage capability on
these frames.
The Frame Alarm connection is on pins 8 and 9 of the RS-232 connector as
discussed in Frame Alarm Connector on page 30.
