PBX Phone System Upgrade

The TNS department is upgrading certain aspects of the PBX phone system during the course of this 2014/2015 academic year to ensure the campus phone system continues to operate efficiently and effectively.

Part of this upgrade includes the upgrade of the 500 series telephones. To minimize disruption, the upgrade will happen in multiple stages, and these users will experience telephone down-time for 10 minutes to 1 hour.

If your phone is one of the phones to be upgraded, you and your department Key Advisor will be notified in advance and again 2 days before the change happens.

If you would like training on your new phone, please contact us at or extension 5000

This upgrade will also position HSU to be able to host our own Voice over IP (VoIP) circuits in the future, which will increase flexibility for mobile users and reduce costs for remote facilities. You can follow the progress of the upgrade on the ITS project portfolio at

Telecommunications and Network Services Deadlines

As of May 2, 2016, our Work Order turn-around time is approximately 2 weeks.

Currently our Work Order completion time is approximately 4 weeks for those Service Requests submitted by the April 13th deadline.

All Service Requests submitted to TNS must be reviewed, questions asked and answered and approvals for charges received.

Once all of this happens, Service Requests can be turned into Work Orders and you can view them in the TNS queue.

Currently there is no estimated completion time for Work Orders received after April 13th, but will most likely be in the first few months of year 2015/2016.

Exceptions can be submitted, but approvals are based on 1 of 3 important factors. 1. a new employee without a phone or Ethernet 2. is mission critical to HSU or 3. poses a life or safety issue

When submitting Service Requests, use the online Service Request system. The PDF form is no longer accepted. If you would like training on the new online form, please contact TNS User Support at ext. 5000.

Requests sent to individuals cannot insure processing.

Please continue to monitor TNS Web Pages for communications and possible changes to the TNS Work Order queue.

If you have questions, call TNS x 5000.
