RE: FCC Order 10-72A1

I am really appreciating the feedback and expertise. For things like elevator phones, I'd prefer to just keep it simple and leave the POTS lines in place. They haven't been a problem by any stretch. My concern is that the carrier would stop offering the service and leave us little time to put an alternative ...

FCC Order 10-72A1

I imagine many of you have or are dealing with the FCC order for all POTS lines to be migrated to another service. This order was issued August 2022. I searched my mail to see if there was any chatter that I missed but it came up blank! We have a remote facility who still has a handful (8) of POTS ...

UMBC has been testing and evaluating a couple different options for our future wireless environment, including both centralized controller and cloud models. As we prepare to make this choice and a sizable investment, how have other schools made and justified their decisions in recent years? Do you have ...

Two way Video, Voice and Text Comms Now in Elevator Standards

Found In Egroup: Communications Infrastructure and Applications \ view thread
I haven't seen any chatter about this, perhaps we are the first ones being directly impacted by a new set of elevator standards that now include video and text based communication, in addition to traditional voice communication, that is now required for new and renovated elevators. This came across my ...

Thank you Jon,This is timely as UMBC is trying to tackle this over the Summer and we'd love to hear the experiences of those ahead of us. One thing that has already presented a challenge, and has been a challenge historically, is that UMBC has generations of equipment because of our refresh cycles. Cloud ...

Publicly Accessible Monitoring Tools

Do you have any public facing monitoring systems that don't require authentication? Our network team has been using a product, Intermapper from Helpsystems for as long as any of us have been around. If you haven't used it or seen it before, it is a lightweight ping/SNMP tool that offers a very basic ...

University IP Phones at Home?

Pre-pandemic I would have never expected to be asking this question, do any of your institutions allow Faculty or Staff to take home their IP desk phones? We've received a couple of requests from staff who want to take their desk phone home and use it there so I hoped to gather some insights from this ...

Chad,Mike Vinson might be onto something here and I encourage you to read this post and his post above. Last night after reading Mike's reply about mDNS settings we dug into our settings a little further. Turns out we were already running in Bridge mode BUT we had no guardrails for limiting the propagation ...

Thank you all for your feedback. Some information that you've asked about so far: The 9800-80's are capable of 6k APs, we currently have an HA pair with a total of 3500. These are also capable of 64k clients, we peak at 20k. These boxes SHOULD be bored. Last night we migrated 10 buildings over to our ...

Cisco 9800-80 Experiencing Load Issues

This past January we migrated our campus over to a pair of controllers from Cisco's new wireless architecture, their 9800 series. By spec, we are nowhere near the capability of what this controller should be able to provide, roughly 1/3 of peak clients and 1/2 of max APs, but every day during the heart ...
