Ring Groups

Purpose:

The Ring Groups form is used to assign directory numbers to ring groups. The form consists of a group pilot number, ring mode, name and a list of all directory numbers belonging to the group. This form supports Range programming.

Use this form when performing the following tasks:

Ring Groups

Conditions

While ring groups can contain network members, only local group membership is displayed in this form.
There is a limit to the number of ONS ports on a single AX or ASU II card that can belong to a specific suite or ring group. When you connect ONS ports that will be configured as part of a common suite or ring group, spread the ports across multiple cards, with a maximum of three ports on any one card.

Field Descriptions

Parameter	Description	Default Value
Ring Group	Enter a unique directory number up to seven digits in length to identify the ring group. The pilot number is the number dialed to access the ring group. See Ring Groups Conditions for valid numbers.	Blank
Local-only DN	Allows you to specify the directory number of the ring group as a local-only directory number in a cluster. This field only appears in the form if your system has been migrated to support Remote Directory Number Synchronization.	Not Selected
Ring Group Mode	Select the mode of ringing: "Ring All" rings all members of the group in unison. "Cascade Ring" rings each member of the ring group individually in the order they are programmed to the group. The next member of the group is rung after the Cascade ring timer has expired.	Ring All
Ring Group Name	System-generated, protected field. Indicates the name under which the ring group is listed in the telephone directory. If no name exists in Telephone Directory form for the pilot number, this field is blank.
COS (Day)	These fields are blank by default. If no Class of Service is programmed, the Ring Group uses the COS of the first programmed member. To specify a COS for all Ring Group members, enter values appropriate to the switch service (Day, Night1, or Night2). Note: You must program these fields before you can enable a ring group with resiliency.	Blank
COS (Night1)
COS (Night2)
Home Element	Displays the name of the primary element for the ring group.
Secondary Element	Allows you to enable and disable resiliency for the ring group. On the primary (local) element, select the secondary element for the resilient ring group. The secondary element is selectable from the members of the same cluster as the primary element. If the primary element fails, the ring group fails over to the secondary element that is specified in this field. You must program the COS fields before you can enable a ring group with resiliency. Refer to the 3300 ICP Resiliency Guide on Mitel Online for instructions on how to configure ring group resiliency. In the this form, the secondary element field displays "Not Assigned" if the group is not resilient. If the secondary element field is blank, the group is resilient but the secondary element name is blank. In the Add and Change window, the secondary element field allows you to enable resiliency. To enable resiliency, select an element from the drop-down list. To disable resiliency, select the "Not Assigned." On the secondary element, this field is read-only. If the Local-only DN box is selected, this field is disabled.	Not Assigned
Call Ringing Timer	This timer is used to time the duration a caller is ringing a ring group. When this timer expires, the caller is redirected away from the ring group. Range: 5 seconds to 300 seconds.	20 seconds
Call Queued Timer	This timer is used to time the duration a caller is queued to a ring group. When this timer expires, the caller is redirected away from the ring group. Range: 5 seconds to 300 seconds.	20 seconds
Cascade Ring Timer	This timer is used to time the duration each available member of a Cascade ring group is rung. When the timer expires, the next available member of the ring group is rung. Range: 5 seconds to 125 seconds.	20 seconds
Overflow Point	If the ring group is unavailable, or the Call Ringing or Call Queued Timer expires, the caller will be redirected to the Overflow Point. See Ring Groups Conditions for valid overflow points. Note: It is strongly recommended that this field be programmed. Otherwise, incoming calls may be dropped.	Blank
Ring Group Members
Member Index	System-generated, protected field. Indicates the number of the member within the group. A station may appear in more than one group.
Number	Enter the directory numbers belonging to the ring group. See Ring Groups Conditions for valid numbers and the maximum members allowed per group.	Blank
Presence	Select whether the member is available (Present) or unavailable (Absent) to receive calls to its ring group. See Group Presence for more information.	Present
Name	System-generated, protected field indicating the name corresponding to the directory number, as entered in the Telephone Directory form. If no name exists for the associated directory number the field is blank.
Home Element	System-generated, protected field that displays the name of the home (primary) element of the ring group member.
Secondary Element	System-generated, protected field. If a hunt group member is resilient, this field displays the name of the member's secondary (backup) controller.
