2361 Modem Users Manual 7-7
A modem can be manually switched from inactive to active for the following reasons:
1) To bring the modem into standard use.
2) To test with a full data payload for quality verification purposes.
3) To track down an unknown, intermittent error, and determine if this modem is the source
of it.
Note: Switching from redundant mode to a non-redundant modem mode does not
require that you replace the redundant ELIMs. You can use redundant ELIMs for
normal modem operation (As long as the Auto-Switching redundancy mode is off).
