“Function” parameter (on the Network 2 Config screen) in “Network” mode −

Internal, Network 1, Network 3, Serial 1

Network 2

“Function” parameter in “Slaved” mode − timing parameter is ignored in

“Slaved” mode

“Function” parameter in “Network” mode − Internal, Network 2, Serial 2

Definitions of the timing sources are as follows:

Internal – The unit’s internal frequency standard (E1 2.048 Mbps ± 50 bps)

is used for all timing.

Network 1, Network 2, Network 3 – Timing is derived from the Network

port recovered clock.

Serial 1, Serial 2 – Timing is derived from the Serial port recovered clock.

Error Status and Alarm Thresholds Table

The unit can be programmed to generate an alarm condition based on a

specific level of performance degradation. The Network Config screens

present a table that provides current error status and alarm threshold

information.

Acceptable alarm thresholds are set for periods of 15 minutes (900 seconds)

sampled every second. The error types listed in the paragraphs below can be

preset to a value between 0 and 900 seconds. Setting a field to “0” (zero)

disables the alarm on that statistic. To effectively disable alarm reporting, set

all fields to “0” (zero).

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 fifteen 1-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.

The four columns of the status table are as follows:

• Status: Displays the current status of the network port.

• Alarm: Displays the alarm value of the Network port. The unit declares an

alarm as soon as the count exceeds the threshold set.

• Count: Displays the number of events or occurrences of this statistic that

have been detected.

• Threshold: Displays a read/write field that can be set to a desirable

threshold.

The table provides error status and alarm threshold information for the

following error parameters:

Sets the Errored Seconds (ES) threshold. An ES is a 1-second period in which

at least one logic error occurred. The default value is 45 seconds.
