The Physical DS1 Port object defines a physical DS1 connector on an MTP2 adaptor card.
Each Physical DS1 Port object is a child of an Adaptor object with adaptor type SG1000 PSTN Signaling Adaptor.
In the EMS System Explorer, the name shown for each Physical DS1 Port indicates
For example, 'Physical DS1 Port (Shelf B, Slot 3, Port 11)'.
To start using DS1 ports, you need to do the following:

Description |
DS1 type | Read only | Specifies the type of DS1 link. Values:
|
Physical encoding | Change Inactive | Specifies the physical encoding used on this DS1 port. This setting must match the encoding of the incoming DS1 line; check with the provider of the line if necessary. Values:
|
Line framing | Change Inactive | Specifies the framing used on this DS1 port. This setting must match the adaptor card type and the framing on the incoming DS1 line; check with the provider of the line if necessary.
Values:
|
Line length | Change Inactive | Specifies the approximate length of the DS1 cable connected to this port. This is used to control the transceivers to ensure adequate signal strength on the line. This field is not valid if Line framing is set to E1 or E1 CRC. Values:
|
E1 Line Impedance | Change Inactive | Indicates the impedance of the E1 line. This field is valid only if Line framing is set to E1 or E1 CRC. Values:
|
Line clocking | Change Inactive | Specifies whether the VP3000 or the remote system provides the clock source for this physical DS1 link. Values:
|
Line status | Read only | Specifies the line status of the DS1 interface. One or more of the following values may be set:
|
Clock reference | Change Inactive | Specifies whether the clocking on this link is used as a general clock reference, or is used just for this link. This option applies only if the Clocking field is set to Loop; if it is set to Local, this option must be set to No. Values:
|
Supported terminations | Read only | Specifies which termination protocols this port supports. Values:
|
Run in Bit Error Rate Testing mode | Change Inactive | Specifies whether Bit Error Rate Testing should be active on this port (the DS1 loops back all received data, and is not available for external communications). Values:
|
Deactivation mode | Change | Specifies how child objects should be deactivated when deactivating this object. Values:
|
Alarm state | Read only | Specifies whether any alarms are currently raised for this object. Values:
|
Alarm log correlator | Read only | Identifier of the log message for the event that caused the last Attention Required alarm state for this object. This field is reset when the Attention Required alarm events field is reset to zero. |
Attention Required alarm events | Read only / Reset | Number of times (since the alarm count was reset) that this object's alarm state has gone to Attention Required. |
Alarm state changed timestamp | Read only | The time (UTC) at which the Alarm state last changed. |
Alarm events reset timestamp | Read only | The time (UTC) at which the Attention Required alarm events was last reset to zero. |
Diagnostics - log level | Change | Specifies the level of logs recorded for this object. Logs with a priority equal to or greater than the priority specified are recorded. Set to Default level to use the system-wide default level. Values:
|
Diagnostics - API trace enabled | Change | Specifies whether API tracing is enabled for this object. If set to True, the Diagnostics - trace tag must be specified. Values:
|
Diagnostics - trace tag | Change | The diagnostics tag inserted into API tracing and PD logging for this object. This tag may include any ASCII characters other than whitespace. |
Requested status | Read only | Specifies whether an administrator has attempted to activate the port. Values:
|
Actual status | Read only | Specifies the current status of the port. Values:
|
