The Physical DS3 Port object defines a port (physical interface) on a DS3 communications card, providing TDM connectivity into the PSTN.
Each Physical DS3 Port object is a child of an Adaptor object with adaptor type PB4000, PB4500 or PB5000.
In the EMS System Explorer, the name shown for each Physical DS3 Port indicates
For example, 'Physical DS3 Port (Controller B, Slot 3, Port 1)'.
In general, you will add Physical DS3 Port objects using the "create all ports" action on the parent Adaptor object, and should not need to create them individually.
To start using DS3 ports, you need to do the following:
![]() |
If you attempt to quiesce deactivate the object when it is using a DS0 for MTP2 links, it will not deactivate until you deactivate the signaling cross connect. (This will usually be because a DS1 over DS3 Port child object is using the DS0.) |
Parameter |
Access |
Description |
Description | Read only | Information about the controller, chassis slot number and port number associated with this port. |
Port number | Create | An identifier for this Physical DS3 Port. The valid port numbers depend on the parent adaptor type, as follows.
|
Additional information | Change | A text field that can be used to store information about the Physical DS3 Port. This field is optional; you can supply up to 64 characters of free-form text. The text wraps to the width of the field on screen, or you can use the Enter key to force linebreaks. |
Channelization | Change Inactive | Indicates whether this DS3 line is channelized into T1 or E1 channels. Values:
|
Line framing | Change Inactive | Specifies the DS3 framing structure used on this DS3 port. This must match the framing on the incoming DS3 line. Values:
|
Line length | Change Inactive | Specifies the approximate length of the DS3 cable connected to this port. This is used to control the DS3 transceivers to ensure adequate signal strength on the line. Values:
|
Line status | Read only | Specifies the line status of the DS3 interface. One or more of the following values may be set:
|
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 at which the Alarm state last changed. |
Alarm events reset timestamp | Read only | The time at which the Attention Required alarm events was last reset to zero. |
DS1 Port Attention Required alarms | Read only | The total number of DS1 Over DS3 Ports (and their child objects) associated with this DS3 Port that are in Attention Required state. |
DS1 Port Attention Required alarm events | Read only / Reset | The total number of times that the alarm state for a DS1 Over DS3 Port child object of this DS3 Port has gone to Attention Required. |
Summary child alarm state | Read only | Summarizes the alarm status for all children of this object. Values:
|
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:
