I may give spectrum a call and see about changing over from our “PRI” to SIP Trunking. This would save alot of headache. Thanks for the suggestion.
There’s nothing stopping you using primary rate over fibre, and there is even hardware on sale to do it. This will not be packet switching based. This equipment presents a standard PRI electrical interface, but transmits over fibre.
To the best of my knowledge, back in the 1980s, before ATM, fibre was the normal way of handling, at least higher level multiplexes, between PSTN switches.
Nothing in the physics of fibre transmission requires packet switching.
It’s probably the case that PSTN operators no longer sell this to new customers, and most will be forcing existing ones onto VoIP.
That is nothing more than a media converter like any other SIP/IP<>TDM gateway/converter on the market. So just like how there is an ONT for fiber to convert it to whatever media is being served.
That is irrelevant here. That was a TDM <> Fiber <> TDM connection for the backbones.
In this case Spectrum is doing fiber to provide multiple services to the location so there is an ONT at the location that is splitting and converting to the media required. So the Internet is being converted to an Ethernet handoff (most likely), the voice is being converted to a PRI handoff. If they have TV services, that will be converted to coax.
Again, the PRI handoff is only there because of the customer’s request/needs.
You could follow the downgrade suggestion from @Santhosh in your other more relevant topic: Can't Install Dahdi with FreePBX 17 - #4 by Santhosh
Appreciate the PRI discussion, which is particularly relevant to users who do not want to deal with directly connecting their FreePBX systems via IP access to the internet – preferring instead the TDM break – but this is perhaps tracking off-topic, so, should we move relevant posts to the “Industry” category instead ?
Yes, I agree. This is off topic from the original post. So moving it would be best.
