PERATION

Station has been selected from the Timing menu. The choices are N

56 K,

64K, and 1.544 MHz.

Station Timing.

When Station Timing is set to either N

56K or N

64K, the N

multiple must also be selected. This field only appears when Station has been
selected from the Timing menu. The N range is 1 to 24. For example, if N =2 and
Station Input Timing is set to N

64K, the unit expects a 128 kHz clock on the

station input port (2

64 = 128).

SLOT X, PORT Y

Timing is synchronized to the external terminal timing clock

supplied from the DTE and connected to the selected port. Selections only appear
for ports installed in the unit. Ports are indicated as Slots 3, 4, 5, and 6 for the
3060 -10; DSU: 1 through 6, and port: A or B.

STA CLK Connector

When this mode is selected, the timing rate must also be set from Station Input
Timing.

Thresholds

The unit can be programmed to generate an alarm condition based on a specific
level of performance degradation. Acceptable alarm thresholds are set for periods
of 15 minutes (900 seconds). The error types listed in the following paragraphs can
be preset to a value between 0 and 900 seconds. A field set to 0 causes the unit not
to alarm on that statistic. To effectively disable alarm reporting, set all fields to 0.

The 15 -minute time frame is not based on the TR 54016 or T1.403 interval
boundaries, but is a time window based on the accumulated counts over the
previous 15 one-minute intervals. In all cases, if the number of actual network-
errored seconds in the previous 15 minutes reaches the preset threshold for the
specified error type, an alarm condition is declared.

Alarm Reset Timer

Sets the length of time after the alarm condition clears before the alarm indication
is removed. A value of zero in this field does not allow the alarm to be
automatically cleared. The default value is 30 seconds.

Sets the errored seconds threshold. The default value is 45 seconds.

SES

Sets the severely errored seconds threshold. The default value is 5 seconds.
