Example command: change system-parameters mlpp

ANNOUNCEMENTS

ASAC Enabled

Note:

The ASAC Enabled field complies with the Unified Capabilities Requirements (UCR) 2008 Change 3 requirements and is approved by Joint Interoperability Test Command (JITC). This field is available only for the USA Department of Defense (DoD) and approved Federal government customers.

ASAC is an extension to the existing Multiple Level Precedence and Preemption (MLPP) calling function which provides directionalization (inbound and outbound awareness) attribute to a calling budget. Administrators can restrict the available call capacity in the inbound and outbound direction with ASAC.

This field is available only when you set the Multiple Level Precedence and Preemption field on the System Parameters Customer Options screen to y.

Valid entry

Usage

y

Makes all ASAC-related fields available on the SIP Trunk Group screen. ASAC also allows Destination Code Control (DCC) functionality.

n

Makes ASAC-related fields unavailable on the SIP Trunk Group screen. Therefore, the ASAC functionality is unavailable for calls. The default value is n.

Attendant Queue Announcement

Note:

This field complies with the Unified Capabilities Requirements (UCR) 2008 Change 3 requirements and is approved by Joint Interoperability Test Command (JITC). This field is available only for the USA Department of Defense (DoD) and approved Federal government customers.

The extension of the attendant queue announcement for incoming precedence calls that are above the Routine precedence level and are placed in the attendant waiting queue.

To enable Attendant Queue Announcement, you must set the Annc Type field on the Announcements/Audio Sources screen to Integrated.

Blocked Precedence Level

The extension of the Blocked Precedence Level announcement.

Busy, Not Equipped

The extension of the Busy, Not Equipped for Preemption announcement.

Service Interruption

The extension of the Service Interruption announcement.

Unauthorized Precedence Level

The extension of the Unauthorized Precedence Level announcement.

Vacant Code

The extension of the Vacant Code announcement.

PRECEDENCE CALLING-DIALED DIGIT ASSIGNMENT

Caution:

Do not change the default Precedence Calling dialed digits unless you are coordinating this change with other companion networks in your system. If the Precedence Calling digits are different across networks, the system does not properly process the calls. Each of the Precedence Calling digits must be different. You cannot use the same digit for two different precedence levels.

Attendant Diversion Timing (sec)

Valid Entry

Usage

10 to 99

blank

Controls how many seconds this type of call rings before the call is routed to the Remote Attendant Route String that consists of any valid telephone number on the network. Attendant Diversion Timing is usually a backup answering position for the remote attendant console. The Remote Attendant Route String does not raise the precedence level of the call.

Default Route Digit

Available only if Worldwide Numbering Dial Plan is enabled. A valid digit is required in this field.

Valid Entry

Usage

0

Voice call (the default value)

1

Circuit switched data call

2

Satellite avoidance call

3

(reserved)

4

(reserved)

5

Hotline voice grade call

6

Hotline data grade call

7

(reserved)

8

(reserved)

9

(reserved)

Default Service Domain

Valid Entry

Usage

0 to 16777215

The system service domain number. This number must be unique within a switching network. The system uses the system service domain to determine eligibility for precedence calling when interswitch precedence calls over non-ISDN trunks occur.

Flash

The digit assignment for Flash precedence level calls. The default is 1.

Flash Override

The digit assignment for Flash Override precedence level calls. The default is 0.

Immediate

The digit assignment for Immediate precedence level calls. The default is 2.

ISDN Precedence Call Timeout (sec)

Valid Entry

Usage

4 to 30

The timeout seconds used instead of the Precedence Call Timeout when the call is from a Multiple Level Precedence and Preemption (MLPP) ISDN-PRI trunk. Default is 30 seconds.

Line Load Control Restriction Level

Determines what stations, based on their COR, are restricted from originating calls.

Valid Entry

Usage

0

Feature not active (no restrictions). This is the default.

2

Restrict stations with a COR assigned to LLC levels 2, 3, and 4.

3

Restrict stations with a COR assigned to LLC levels 3 and 4.

4

Restrict stations with a COR assigned to LLC level 4.

Precedence Call Timeout (sec)

Valid Entry

Usage

4 to 30

The number of seconds a precedence call remains in call waiting status before it is diverted. A busy user receives a precedence call waiting tone only if the incoming call cannot be connected and cannot preempt the user. The called party hears the tone every 10 seconds until answered or the administered time-out occurs. If ignored, the caller is diverted to an attendant or a call-forwarded station. The default is 30 seconds.

Preempt Emergency Call

If enabled, allows preemption of an Emergency 911 call made from a preemptable station by a higher precedence call.

Note:

Emergency call preemption occurs only in case of trunk and endpoint preemption. In case of network preemption the emergency calls are not preempted, irrespective of the settings for Preempt Emergency Call? flag.

Priority

The digit assignment for Priority precedence level calls. The default is 3.

Remote Attendant Route String

A user-defined telephone to which a precedence call can be routed when no console or night telephone is administered. Accepts from 1 to 24 digits.

Routine

The digit assignment for Routine precedence level calls. The default is 4.

WNDP Emergency 911 Route String

This route string is outpulsed when a user dials either 911 and waits for the interdigit timeout, or dials 911 followed by #. This dialing option only works when the WNDP Flash FAC is 91. Use a trunk access code (TAC), the AAR or the ARS access code, a WNDP access code, or an extension. For a WNDP access code, use the access code for the lowest precedence calling level in the system. Accepts from 1 to 24 digits.

Note:

An Emergency/911 call is a call that routes using the ARS table with the call type defined as either alrt or emer.

Worldwide Numbering Dial Plan Active

Enables or disables the Worldwide Numbering Dial Plan. Disabled by default.
