# NetworkInterface.T1E1[x].AlarmMode

For T1 interfaces, specifies if alarm conditions are declared immediately or after a specific period of time when an alarm event (for example, out of frame) occurs. This keyword is not applicable for E1 interfaces.

#### Syntax

NetworkInterface.T1E1[x].AlarmMode = mode

x = 0-(n-1) (0-based trunk number or range of trunk numbers where n equals the number of trunks on the board.)

#### Access

Read/write

#### Type

String

#### Default

T1_US

#### Allowed values

The allowed values are:

Value | Alarm | Time to clear | Time to set
T1_US | Red | In frame condition for approximately 16.5 seconds | Out of frame condition for approximately 2.55 seconds
Yellow | Far end alarm clear for approximately 0.5 seconds | Far end alarm active for approximately 0.5 seconds
T1_G706 | Red | Immediate | Immediate
Yellow | Immediate | Immediate

The T1_G706 value is based on the G.706 ITU recommendation that signals be debounced. It does not specify an exact amount of time to wait.

#### Example

NetworkInterface.T1E1[x].AlarmMode = T1_US
