AtHoc : Mass Notification System

NSA Mid-South has established a Computer Desktop Notification System (also referred to as AtHoc) to send alert messages to all military, civilian, and contractor employees in the case of an emergency.
The CDNS is an instant communication tool for Navy commands to notify installation personnel during an emergency event. Using the AtHoc software tool available, alert messages can be delivered via NMCI computers, email, work phone, and/or personal devices (home phone, email, cell phone, etc).
For successful operation of the CDNS system, it is important that all NMCI users physically located at NSA Mid-South review and update their contact information.
The AtHoc software uses the NMCI computer name to identify the recipients of CDNS notifications. Any computer name with the MILL, GCML, GSML, AHML, PTML, or GYML site codes will receive the CDNS notifications sent by the NSA Mid-South Emergency Management Department.
This action does not apply to employees of tenant organizations who are not physically located at NSA Mid-South.
All users should follow the procedures provided below to update and maintain their personal contact information.
On NMCI Computers in the icon tray, find the purple globe icon. If the computer does not display the “purple globe”, if it is faded out, or if it is grayed out with a red X, users must call the NMCI Help Desk at (866) 843-6624 and request that the software be removed and reinstalled (Help Desk Menu guide: Option 1 for Unclassified, Option 3 for software, Option 2 for other software).
All CDNS end-users should utilize the procedures on the following pages to update and maintain their personal contact information on the AtHoc/CDNS System.

Click on the “Show hidden icons” triangle in the bottom right corner.
Right click on the CDNS (purple ball) icon in the toolbar and select Access Self Service.
2. The NSA Mid-South window will open (as displayed below) and will automatically default to the Inbox Tab. It should display recent alerts. However, it may ask what channels you wish to display. If this is the case, DO NOT change information displayed on the Inbox Tab.
3. The information contained on the My Info Tab should be up-to-date. If any data fields are incomplete or incorrect, please update the respective fields with the appropriate data. If changes are made, please click on the Save button at the bottom right of the screen.
Your username will be here
4. All end users should access the Devices Tab and are required to enter work phone (to include government-issued cell phones) and work email addresses. Users are highly encouraged to also enter personal contact data to enable receipt of up-to-date information (i.e.: base closures, report to work delays, etc.).
5. Click on Save at the bottom of the window to save your contact information.
6. Exit CDNS by clicking on Sign Out in the upper right corner of the screen.

What to Expect
The AtHoc System can contact you in a variety of ways.

1) The Desktop Pop-Up
a) This Alert slides out from the right corner of your screen. Sometimes a sound may accompany the message to get your attention. You cannot close the alert without acknowledging the alert. Alerts are sent out for specific times. This means if an alert is sent out on a Saturday with only a 1 hour length, and you aren’t in the office, you won’t see it come Monday. Here is an example of what a Desktop Pop-Up may look like:
b) Some alerts may take you to a website to give you more information. For example the button “Acknowledge and show more info” in the example above may show you a website describing the Tornado Warning area, duration, etc.
Typically the EMO or CDO

2) E-Mail Notification
a) E-Mails can be sent to any address you specify in the Self Service as described above. Below is an example of an E-Mail notification sent with the Desktop Pop-Up example above:
b) E-Mails to non addresses may appear different, though the message is the same, as shown here:

3) Phone Notification
a) When receiving a phone notification you may be required to hit the number 1 before the message continues. The voice is computer generated and may speak too quickly, listen carefully and you will be given the option at the end to have the message repeated.

4) SMS Text Messaging Notification
a) You will receive a text message with the alert message.

For those without NMCI computer access, you can request AtHoc Registration by emailing
