Alternate Dial-Out Directory for Alarm or Trap. Specifies whether a call that cannot be
completed (busy, no answer, etc.) is retried using an alternate phone number. This affects
calls that are initiated in an attempt to send an alarm or trap message to the modem port
or carrier external communication port device. The alternate phone number to try is
contained in one of the five call directories. If call retry is enabled, the initial call is retried
at the original number once before a call attempt to the alternate number is tried. If the call
to the alternate number is unsuccessful, it is also retried once. The alternate dial-out
option applies to each alarm/trap event. Once a call for an alarm/trap message either
completes or fails all retry attempts, the next alarm/trap attempts to establish a call to the
phone number contained in the alarm directory.
None – Specifies that alternate alarm dial-out is not performed if a call cannot be
completed to the telephone number contained in the alarm directory.
1–5 – Specifies the call directory that contains the phone number to call if a call cannot be
completed to the telephone number contained in the alarm directory.
NOTE: For carrier-mounted DSU/CSUs, this configuration option is only available if the
communication port is enabled for an external device.

Excessive Error Rate Threshold. Sets the error rate threshold that determines if an
Excessive Error Rate (EER) condition is declared. This rate is determined by the ratio of
the number of CRC6 errors to the total number of bits received over a set period of time.
Select from the following:
10E-4 – EER is declared if more than 1,535 CRC6 errors are detected within
10 seconds (factory default).
10E-5 – EER is declared if more than 921 CRC6 errors are detected within 60 seconds.
10E-6 – EER is declared if more than 92 CRC6 errors are detected within 60 seconds.
10E-7 – EER is declared if more than 9 CRC6 errors are detected within 60 seconds.
10E-8 – EER is declared if more than 41 CRC6 errors are detected in three 15-minute
intervals.
10E-9 – EER is declared if more than 4 CRC6 errors are detected in three 15-minute
intervals.
