MLPP

Purpose:

Use the MLPP form to enter both system-wide and subscriber-specific MLPP data. Use this form when performing the following tasks:

MLPP Programming

Conditions

This form can be viewed or edited only if the Multi-Level Precedence and Preemption (MLPP) Application has been purchased.
Any changes to this form must be manually reflected on all concerned systems using the System Administration Tool.

Field Descriptions

MLPP System Settings
Parameter	Description	Default Value
Default Service Domain	A Service Domain is an arbitrary division of switching resources among sets of users. Users in different Service Domains can call each other so long as resources are available. However, only users in the same Service Domain can preempt resources. The Default Service Domain is applied to all calls for the switch, with the exception of calls for extensions programmed with unique Service Domains. Enter a value in the range of 0 to 16777215 digits.	0
Call Diversion Timer	The Call Diversion Timer runs for every precedence call, from the start of the call through ringing, call forwarding, call rerouting. It terminates when the call is answered, or when time limit expires and the call is routed to the Call Diversion Directory Number. Enter a number in the range of 15 to 45 seconds.	30 seconds
Call Diversion Directory Number	Assign a valid directory number to which calls are routed after the Call Diversion Timer expires. Valid DNs include IP and DNI set Prime lines, ONS lines, Hunt group pilot numbers, remote DNs, 5540 IP Console DNs, and SUPERCONSOLE 1000 DNs. Speed Calls and Multi-line key appearance DNs are not allowed. The field may be left blank if the Call Diversion Timer handling is not required. Notes: Using a SUPERCONSOLE 1000 or 5540 IP Console as the Call Diversion Directory Number is recommended, especially for larger installations as calls to a console are queued and answered in order of precedence. No such queuing is provided for other devices types. For clustered systems, if an attendant console is not required, a resilient IP set is recommended for use as the Call Diversion Directory Number. If an attendant is required, one for each controller in the cluster is recommended.	Blank
MLPP DN Setting
Directory Number	The system generates the directory number list based on the programming of single line sets and broadcast groups (prime and non-prime numbers). Other directory numbers (consoles, test lines, etc.) do not appear.
Preemptable Subscriber	Designate whether a subscriber is preemptable or not. Defaults to Y (yes) for newly created subscribers when the MLPP Application is enabled.	Yes
Service Domain	(Optional) Program a unique Service Domain for the extension. If the field is left blank, the extension uses the Default Service Domain. If a user originates a call on a non-prime line of a multiline set, the Service Domain for the call is determined by the contents of this field as programmed against the prime line for the set. Even extensions that have Preemptable Subscriber set to "No" may be assigned a Service Domain.	Blank
Maximum Precedence Level	Program the highest precedence level that a user may choose for a call. Valid entries are shown below along with equivalent precedence digits that the user would dial. The highest precedence level is Flash Override (digit 0); the lowest is Routine (digit 4). If the user dials a higher-than-permitted precedence digit, the system applies intercept handling to the call. If a user originates a call on a non-prime line of a multiline set, the maximum precedence level for the call is determined by the contents of this field as programmed against the prime line for the set. Even lines that have Preemptable Subscriber set to "No" may be assigned a maximum precedence level.	Routine

The MLPP Precedence Levels are provided in the following table:

Precedence Level	Precedence Digit
Flash Override (highest)	0
Flash	1
Immediate	2
Priority	3
Routine (lowest)	4
