Previous Virtual Breakfast Briefing: The Great Switch-Off of PSTN and ISDN

15 million lines (PSTN, ISDN and ADSL) will be switched off in the next 4 years in the UK, believe it or not, you are running out of time. While many organisations have migrated core voice services to SIP, Teams or Zoom, many still retain these legacy services at satellite sites and/or for nuanced services including lift lines/alarms/entry systems, for example. Have you planned your timely exit from these legacy services?

We very much hope you’ll join us for this virtual live-only, interactive event on Thursday 24th February 2022. John Waterhouse, CEO, and Craig Northveth, CTO, will be joined by Adrian Joyce, Head of Consulting. This is an opportunity for you to ask questions, hear from your peers and learn from TNC’s wealth of unique market insight and expertise.

Topics to be included:

  • Discussion around this seismic change to the UK telecoms’ estate
  • What organisations are doing to ensure they aren’t caught out by this change
  • Potential replacements and how long these may take to put in place
  • Have you considered all the possible impacts to your organisation?

Event Details:

  • When: 8.30 – 10am on Thursday 24th February 2022
  • Where: Secure Zoom Meeting
  • Topic: The Great Switch-Off of PSTN and ISDN
