IDT Port

The IDT Port object is a child of the Media Gateway object. It identifies an Integrated Digital Terminal, which is the VP3500 end of an interface group, over an Interface Group consisting of 28 DS1s connected to a DLC serving POTS telephones.

The IDT Port must have a child IDT interface object for each DS1 in the Interface Group.

To create and activate an IDT Port, you need to do the following.

Object-Specific Actions
Inhibit EOC PPS Prevents Path Protection Switching for the EOC on this IDT Port. No switching will be possible, regardless of whether it is initiated automatically or requested by the EMS user or the DLC.
Enable EOC PPS Allows Path Protection Switching for the EOC on this IDT Port if it was previously inhibited.
Request EOC PPS Requests a Path Protection Switch for the EOC.
Inhibit TMC PPS Prevents Path Protection Switching for the TMC on this IDT Port. No switching will be possible, regardless of whether it is initiated automatically or requested by the EMS user or the DLC.
Enable TMC PPS Allows Path Protection Switching for the TMC on this IDT Port if it was previously inhibited.
Request TMC PPS Requests a Path Protection Switch for the TMC.


The object-specific actions are available only if both the Primary Control Channel and Secondary Control Channel fields are set.


Parameter

Description
IDT Port name Change Inactive The name of this IDT Port. This name is used in the EMS User Interface to identify this IDT Port, and must not match the name of any other IDT Port. Specify a name of 1 - 16 characters, which may be uppercase letters, digits, or any of the following special characters:
+
- _ & ! ' | = # ? . ; [ ] ^ ' { } ~
Protocol stack status Read only The status of the IDT Port in the GR303 Protocol Stack. It is not possible to make GR303 calls using this IDT Port unless the GR303 Status is Active. Values:
  • Inactive
  • Pending interface activation
    The IDT Port cannot start because the child IDT Interface required for its control channels is not yet active.
  • Starting
  • Started
  • Stopping
  • Failed
Primary Control Channel Change Inactive The interface used to carry the EOC and TMC Control Channels. A value of None means that no primary control channel has been specified; in this case you will not be able to activate the port.
Secondary Control Channel Change Inactive An alternative interface that can carry the EOC and TMC Control Channels. A value of None means that no secondary control channel has been specified. If you have selected an interface rather than None, this interface must be different from the Primary Control Channel.
EOC - active channel Read only The IDT interface currently used by the Active EOC. The Active EOC will use timeslot 12 on the specified IDT Interface, which means that timeslot 12 will not be available for GR303 calls.

  • Configured
  • Out of service
  • In service
EOC - standby channel Read only The IDT interface currently used by the Standby EOC. The Standby EOC will use timeslot 12 on the specified IDT Interface, which means that timeslot 12 will not be available for GR303 calls.
EOC - standby channel status Read only The status of the Standby EOC used by this IDT Port. Values:
  • Configured
  • Out of service

EOC - path protection switching inhibited Read only States whether Path Protection Switching is inhibited for the EOC Control Channel. Values:
  • Yes
  • No
EOC - force all path protection switches Change When this field is set to True, all EOC Path Protection Switch requests will be 'forced'. Values:
  • True
    The PPS will proceed, even if the Standby EOC is Out-Of-Service.
  • False
    It is not possible to request an EOC PPS onto an Out-Of-Service interface.
EOC - last action status Read only The status of the last EOC action on this IDT Port. Values:
  • No last action
  • Initiate PPS in progress
  • Initiate PPS successful
  • Initiate PPS failed

  • Enable PPS in progress
  • Enable PPS successful
  • Enable PPS failed
EOC - last action time Read only Timestamp of the last state change of the EOC - last action status field.
TMC - active channel Read only The IDT interface currently used by the Active TMC. The Active TMC will use timeslot 24 on the specified IDT Interface, which means that timeslot 24 will not be available for GR303 calls.
TMC - active channel status Read only The status of the Active TMC used by this IDT Port. Values:
  • Configured
  • Out of service
  • In service
TMC - standby channel Read only The IDT interface currently used by the Standby TMC. The Standby TMC will use timeslot 24 on the specified IDT Interface, which means that timeslot 24 will not be available for GR303 calls.
TMC - standby channel status Read only The status of the Standby TMC used by this IDT Port. Values:
  • Configured
  • Out of service
  • In service
TMC - last path protection switch time Read only Timestamp of the last successful TMC Path Protection Switch for this IDT Port. Path Protection Switching may be automatic, or may be initiated locally, or remotely.
TMC - path protection switching inhibited Read only States whether Path Protection Switching is inhibited for the TMC Control Channel. Values:
  • Yes
  • No
TMC - force all path protection switches Change When this field is set to True, all TMC Path Protection Switch requests will be 'forced'. Values:
  • True
    The PPS will proceed, even if the Standby TMC is Out-Of-Service.
  • False
    It is not possible to request a TMC PPS onto an Out-Of-Service interface.
TMC - last action status Read only The status of the last TMC action on this IDT Port.
