# Line Status: Multi-Color (LED) Indication

Multi-Color LED line status is a Class of Service option that uses color to indicate to set users whether activity on a line key is of direct concern to them, or to another member of the associated Broadcast Group
A directory number programmed to appear on multiple devices constitutes a broadcast group. There are two types of broadcast groups: Non-Prime Line and Prime Line. A Non-Prime Line group is a directory number programmed on one or more devices that is not the prime line on any device. A Prime Line group is a directory number programmed on button 0 of a phone. Server-based variants of MiVoice Business that use x86 processors, MiVoice Business for Industry Standard Servers MCD-ISS), Multi-instance MiVoice Business, and Virtual MiVoice Business, up to 250 appearances of the directory number can appear on one or more devices. For all other 3300 ICP/MiVoice Business call control platforms, up to 32 appearances of the directory number may appear on one or more devices..

The table below shows the line status for various line types such as Single, Key System
A multiple line phone system for small business. It offers basic features and intercom. It is usually configured in a squared fashion (all lines on all sets). Some key systems may be configured in a pooled environment to emulate small PBX's. Only one member of a Key System Group can use the line at one time. See also Multicall Group., and Multicall Group
A line appearance type that lets multiple telephones share the same extension number. All Multicall group members can use the line simultaneously. See also Key System lines..

NOTES

1. The "Red" color specified in the table represents the color that is currently used when lighting personal keys on Mitel sets. On some sets, this color would be more accurately described as orange.

2. The following Ringing and Hold Flash rates specified in the table refer to those currently in use in MiVoice Business for Ringing and Hold states:

- 750 ms off – 750 ms on: Ringing.

- 150 ms off – 150 ms on: Hard Hold Local, and Hard Hold Remote on the 5560.

- 150 ms off – 600 ms on: Hard Hold Remote, except on the 5560.

3. An appearance of a Multicall group acts as an independent line, such that the line statuses of the other appearances of the group do not affect the LED status of the appearance. For this reason, the table does not specify an LED status for Multicall groups and remote line statuses. The exceptions to this rule are Hard Hold Recall Call Park Recall, and Transfer Recall, where the recall rings all of the members of the Multicall group, even though a specific member put the call on Hold or transferred it.

4. The term "Transfer Recall" encompasses recalls where the party to which the call was transferred rings but does not answer, and camp-on recalls, which follow a Transfer to Busy operation.

5. In the above scheme, prime and non-prime groups behave in the same way.

6. In the above scheme, "remote" means that someone else in the group has put the call in the state specified. In the case of Recall, "remote" means that someone else in the group initiated the original operation that eventually resulted in a recall.

7. Parking a call does not cause LEDs associated with line keys to light.

8. Held and parked parties are still considered in Call Answer state.

9. On a given device, all appearances of a group being rung by a given call will display the same color. Furthermore, if one of these appearances should be in Ringing Flash - Green state, all will be in Ringing Flash - Green state, as the call is of direct concern to the device's user.

10. The Multi-Color LED feature is limited to sets using the MiNET protocol. It does not apply to SIP sets or dual mode sets running in SIP mode.

11. Keyline appearances of SIP sets will not receive the LED treatment stated in the table, even if they are hosted by MiNET sets.

## Direct Trunk Select Lines

When a Direct Trunk Select (DTS) key is programmed on a set supporting Multi-Color LED indication:

- as a Single line, the LED will always be Green, whether flashing or solid

- as a Key System line, the LED will be Green if in use locally, and Red if in use at a remote set.

If the activity on the the DTS line trunk is not associated with an appearance of the line, the LEDs of all the DTS line appearances will be On-Red.

## Hunt Groups

When a call comes to a Hunt group, it is distributed to the first member DN. This DN represents a Broadcast Group
A directory number programmed to appear on multiple devices constitutes a broadcast group. There are two types of broadcast groups: Non-Prime Line and Prime Line. A Non-Prime Line group is a directory number programmed on one or more devices that is not the prime line on any device. A Prime Line group is a directory number programmed on button 0 of a phone. Server-based variants of MiVoice Business that use x86 processors, MiVoice Business for Industry Standard Servers MCD-ISS), Multi-instance MiVoice Business, and Virtual MiVoice Business, up to 250 appearances of the directory number can appear on one or more devices. For all other 3300 ICP/MiVoice Business call control platforms, up to 32 appearances of the directory number may appear on one or more devices. (possibly containing a single member). The LEDs associated with the broadcast group behave as if this was a direct call to the group and LED will flash Green. Should the call go unanswered, the LEDs will turn off. The call is then redistributed to the next Hunt group member DN. This DN represents a second broadcast group. The LEDs associated with this group behave as if this was direct call to the group. And the cycle repeats itself until the call is answered or dealt with otherwise. When a member of hunt group calls another extension the color of prime line would be green when in dialing state. This is similar to any non-member extension making a call

## ACD Groups

An ACD call distributed to an ACD agent will cause the agent's LED to flash Green since the call is for the agent.

## Ring Groups and Personal Ring Groups

When a call is made to a Ring group, it is distributed to the individual member DNs. Each individual member DN is treated as if the call were directly to it. The LEDs of all of the ringing members' appearances will be in Ringing Flash-Green state. Once the call is answered by a member, the appearances of the other members of the Ring group go idle. From then on, the appearances associated with the member that answered the call are treated as if the call had been directly to the member's DN. The Ring group is no longer of consequence.

## Supported Device Types

Multi-Color LED Support is available on the following set types that support green LEDs:

5010 5020 5207 5212 5224 5220 5220dm | 5312 5320/5320e 5324 5330/5330e 5340/5340e 5360 5560 (Turret)

Furthermore, these sets must be operating in MiNET mode.

Multi-Color LED Support is not available on SIP sets.

Sets for which Multi-Color LED Support is disabled, will continue to use the single LED color they currently use to indicate line status.
