Upon my arrival at Lehigh University, one of the first major projects for the organization was to replace our near end of life (EOL) traditional phone PBX system with modern Voice over Internet Protocol (VoIP). With 4,000+ phones, life safety requirements and integrated phone services, this is a massive undertaking by the telecommunications team. After vendor selection, contract negotiations and initial setup, the team started migrating Library and Technology Services during late summer with general rollout beginning in September. With the large number of users required to be migrated, the team developed a self service deployment process that allows users to quickly setup and migrate to the new phone system. We have staff on hand during the migrations to assist with any issues or questions.
Towards the end of November, the Cisco Unified Communications team reached their first user migration milestone of 500 users, approaching 600+ users at the end of 2017. While we still have a long road ahead of us, it’s reassuring from the feedback we received so far that the self-service process is working well and users are generally pleased with the new system. I encourage faculty and staff to respond to the surveys so we can tweak our processes for the next round of migrations. Training is available prior to and after the migrations. Please refer to the training schedule for upcoming sessions.
For those that have not been migrated, a reminder of some key links for the project.
As we begin the new year, look for announcements on feature enhancements to the phone system such as off campus access, fax services and other collaboration services.

After students finished Spring Semester 2017, Technology Infrastructure and Operations team went into Drown Hall to perform a wireless assessment to develop a plan for providing complete wireless coverage. Data from the assessment in May was used to strategically place Access Points (APs) throughout the building to provide optimal wireless coverage and performance. Working with Dawn Keetley, Professor of English and Chair of the English Department, we scheduled the installation of pathway and wireless APs during the summer in preparation for the upcoming academic school year. The project was completed at the beginning of August with 33 new APs and one new building access switch installed. We are excited to bring a much needed wireless upgrades for the English department and students that use Drown Hall for academics and research.
As we wrap up our 2016 activities and begin to discuss plans for 2017, below list some key accomplishments for TIO in 2016. While, this is by no means is a complete list, it encompasses the major activities that defined our team. Through the dedication, hard work, commitment of TIO, LTS and various teams throughout Lehigh University we were able to meet our goals in providing a secure reliable cyberinfrastructure for faculty, staff and students.
- Mountaintop Fiber Project was approved, funded and awarded. When completed, we will have diverse fiber paths from Asa Packer Campus to Mountaintop Campus. These paths are crucial in supporting new academic and research initiatives such as DataX.
- Throughout the year, we upgraded various building infrastructure wired and wireless networks. The results of these upgrades provides higher capacity, performance and stability for faculty, staff and students. Buildings that were part of our upgrades include Mudd, Packard Lab, Flatiron, and the Police Station.
- The networking team, successfully engineered and piloted a next-generation wireless architecture at Warren Square. This hospitality design enhances wireless connectivity while providing 1 GB wired connectivity via 2-ports for those that still required wired connections. Pilot was well received and will be expanded pending funding.
- For Asa Packer Campus, we dramatically increased the fiber-optic capacity, which will be required to support future Lehigh University growth as discussed in the Path to Prominence announcement.
- Along with physical wiring, we replaced various building end of life (EOL) network switches. With the switch lifecycle management performed in 2016, nearly all of lower campus switches are now fewer than 5 years old. Not only do these switches provide higher speeds, better performance and stability, but they support new features such as Power over Ethernet that provides power to VoIP phones.
- The Infrastructure Operations team continued to manage our data centers and operations. The team made many Data Center improvements such as adding UPS and HVAC to our secondary data center, additional UPS in main data center, assisted with the installation of the new High Performance Cluster (HPC), modernized and reduced systems using virtualization technologies and performed various data center cleanup activities.
- As we look to replace our aging PBX telephone services with Voice over IP (VoIP), the telecommunications team setup a Cisco Unified Communication sandbox.
- Completed Windows 10 upgrade and deployment to public sites and classrooms campus-wide as well as virtual public sites.
- For special devices that can’t connect to the secure wireless network, the networking team engineered and deployed LUNA, a mac-based authentication for IoT networking.
- The systems engineering team completed the effort to consolidate all our application license servers.
Looking forward to a new and challenging year ahead!
As students take a much needed refresher after finals, LTS was busy performing updates to systems, applications and infrastructure. One of those infrastructure improvements completed over the winter break was increased wireless coverage in Packard Lab. Students returning to Packard Lab should see an increase in wireless coverage and performance as the team doubled the amount of wireless access points. Many buildings at Lehigh University pose interesting challenges for wireless due to architecture and structure, but the team performed an in-depth analysis and mapping to fill in weak gaps. Special thanks to Jon Hutchinson, Pat Murphy, Brian Posivak and Luis Rosario for their hard work in getting this completed.
If any faculty or students have any issues with the wireless changes in Packard Lab, please contact the LTS Help Desk: call 610-758-HELP (4357), log into online chat, email email@example.com, or text 610-616-5910. However, free feel to reach out to me if you have any general concerns or feedback.
After 5 months, Library & Technology Services completed the Mudd Building Rewire Project. Technology Infrastructure and Operations (TIO) started planning and engineering the network upgrades back in the spring of 2015. The goal of this effort was to replace old category 3 ethernet cabling dating back to the 90s with new modern category 6a cable capable of handing gigabit network speeds. In addition, modern networking switches and data closet architecture were deployed. This was the first project that we utilized blockouts to manage the endpoint connections by placing physical locks on unused ports. End users can requests blockouts to be removed. These blockouts enable us to reduce our costs and improve security. When the project was completed, 936 Cat 6a jacks were deployed, 346 connections activated and 101 phones relocated or newly installed.
Congrats to the TIO team members Lizanne Hurst, Pat Murphy, Jeff Deschler, Debbie Henritzy, Luis Rosario, Brian Posivak, Kent Smith, Lisa Luchini, Munroe Sollog, Jon Hutchinson and Mark Miller. Special thanks to Jim Roberts for being our interface for the users in the Mudd Building during this project.
