Configure ISDN PRI DS1

This step is optional.

Enter the following information.


Parameter

Description
Excluded timeslots Timeslots on this DS1 that are not available for use as D-channels or B-channels. By default, all channels are available for use, but you can restrict the range of available channels (for example to provide partial T1 capacity). You cannot activate this DS1 if all of the timeslots are excluded. Select zero or more of the timeslot values 1 - 24. Timeslot 24 must not be excluded if the DS1 supports a D-channel.
PBX capacity groups - Timeslot 1-24 The value of this field applies only if the ISDN PRI is used for an ISDN PBX. It appears once for each of the DSI's 24 DS0 timeslots, except for those that have been excluded using the Excluded timeslots field. Specifies the capacity group for each of the DS0s from 1-24. These are used by the PBX and Direct Inward Calling Number objects to reserve capacity for incoming calls to the PBX. For more details, see Operations Manual: Call Services and Subscribers. Values:
  • Default
    Call to numbers without a specific (1-5) capacity group use Default slots. Additionally, if all of the timeslots for a particular capacity group are in use, additional calls to that group will use default timeslots (if available).
  • 1
  • 2
  • 3
  • 4
  • 5
Deactivation mode Specifies how child objects should be deactivated when deactivating this object. Values:
  • Normal
    Release all active calls normally before deactivating the object.
  • Quiesce
    Deactivating the DS1 in quiesce mode will wait for all existing calls to complete before the DS1 is deactivated. No new calls using this DS1 can be activated during this deactivation period.
  • Abort
    Deactivate the object and end all its calls immediately. (This may result in errors at remote systems.)
If a Normal or Quiesce deactivation is already in progress, you can force a faster deactivation by changing the value from Normal to Quiesce or from Quiesce to Abort.
