Funny thing about this is we have been steadily getting rid of all of our t=
1 and ds3 circuits and replacing them with metro-e or cable based services =
at much better price/Mbs. However, when we went to VOIP and wanted to do si=
p trunking with qwest, they needed to deliver this over t1, otherwise is wa=
sn't cost effective.

Subject: "Is TDM going the way of dial-up?"
I've noticed over the last 3 years or so that TDM, specifically T-1, access
and transport has been in a steady decline. Customers are moving to FTTH
and cable, or going WiMAX and Metro-Ethernet. Ethernet seems to have taken
an even bigger bite out of DS-3. The bigger pipes seem to favor ethernet. =
A
recent upgrade from OC-3 to GigE transport actually saved us a large chunk
of money.
I'm wondering if others are seeing the same behavior, if it's
market-dependant, or if I'm just imagining things. I'm working on building
new infrastructure and my current thoughts are to minimize my TDM
footprint. It would be useful to get a better feel if this is an overall
trend or something local.
Thoughts?
Thanks,
