Setting System Parameters
77
All of the parameters discussed in the remainder of this table are stored in the CO line unit card NVRAM
and therefore will not normally change when power is cycled or cards are removed and reinserted.
E Auto Logout
Time DISABLED After logging on to a system, you are automatically logged out after a
time determined by the Auto Logout Time parameter:
• DISABLED: The user is never automatically logged out.
• 5: The user is automatically logged out after 5 minutes.
• 30: The user is automatically logged out after 30 minues.
• 60: The user is automatically logged out after 60 mines.
F Metered Tone
Frequency DISABLED Metered tones are used for out-of-band signaling with coin telephones,
typically in international markets. A special channel card is required to
support this function.
• DISABLED: No tones are recognized.
• 12: Recognizes 12 kHz as the signal frequency.
• 16: Recognizes 16 kHz as the signal frequency.
G Ring
Frequency 20 Determines the frequency of the ringing voltage on the subscriber line.
The values can be set to one of the following parameters:
• 20: The ring generator is set to 20 Hz.
• 25: The ring generator is set to 25 Hz.
• 30: The ring generator is set to 30 Hz.
H HDSL ES
Alarm
Threshold DISABLED Sets the number of Error Seconds required before a minor alarm is
generated (dependent on the setting of the Alarm on HDSL Threshold
parameter). The count of Error Seconds is reset to zero when the reset
function is used on the HDSL Performance History status screen. The
values can be set to one of the following parameters:
• DISABLED: No minor alarm is generated, regardless of the number
of error seconds.
• 17: A minor alarm is generated after 17 error seconds.
• 170: A minor alarm is generated after 170 error seconds.
I HDSL Margin
Threshold 4 This parameter sets the HDSL margin threshold. If the HDSL margin
attains a value equal to or less than the setting for this parameter, a minor
alarm is generated (dependent on the setting of the Alarm on HDSL
Threshold parameter).
A default setting of 4 indicates that a minor alarm occurs when the
HDSL margin is
≤
4 dB.
The HDSL Margin Threshold can be set between 0 dB and 15 dB
(0 dB = Disabled).
