Hey,

In some DCs I've done mutual OOB swaps with other telcos in the same
suite, this is usually cheap or free (excluding the one time xconnect

We consciously decided to not ask or accept OOB swaps, because of fear
that they might be provisioned outside processes which might make it
impossible to repair them through normal commercial processes, which
would potentially cost lot of downtime and NOC's resources.

Sometimes the DC provider has an OOB connectivity service that uses
separate transit providers than we use and this often cheap too. Again
this is often bespoke per DC/colo provider though.

MRC quotes I have 400USD Equinix, 288USD Terramark, 300USD Coresite.
Compared to PSTN which we see at 90-150USD. This makes me less
inclined to focus on HW CAPEX and optimise for HW/SW that tooling and
people already support.

Your PSTN figure doesn’t include the cost of the XC to bring that POTS line
into your suite/cage/cabinet.

Once you add that in, It looks to me like you probably exceeded the OOB service
price in each of the cases quoted above.

The most scalable solution I've been involved in so far is VDSL. Here
in the UK lots of DCs are on-net for the national incumbent VDSL

I think WAN indeed is very market situational, and if you need to
support world, it is beneficial to have solution which supports many
WAN options, without needing external boxes and external power bricks.
We try to do just ethernet, but even that is already being provided as
copper, fibre and in one market with PPPoE, all which are non-issues
by going with Cisco. I do wish I had second option, I do wish JNPR SRX
would support async serial ports.
