We're the phone company, we don't need route diversity

To make things worse, many of the new CLECs don't have adiquite trunking
to the 911 tandems or PSAPs. Many of my CLEC customers try to only run the
minimum number or channels to get approved. Most of them also run all of
the 911 over the same circuit or if they have more then one, out of the
same MUX.

In the Topeka, Kansas SWBT failure, one of the CLECs did issue a press
release pointing out their network was not affected by the software
problems on SWBT's telco switch.

There are a lot of CLECs with very poor procedures and preparedness,
and 9-1-1 trunks have interesting issues due to their very high
visibility and requirements. Most CLECs rely 100% on the ILEC to
provide 9-1-1 tandem services. But don't assume the ILECs are as good
as they like to imply. For example, I posted about a Southwestern
Bell outage on May 27 in central Missouri on NANOG earlier. SWBT
filed their Final Outage Report with the FCC last week.

A fiber cut near Lake St. Louis on the main I-70 cross-state highway took
out operator, inter-switch, long-distance (inter and intra lata) service
for 21 Central Offices and 13 9-1-1 answering points affecting 205,000
customers for 5 hours. SWBT's analysis indicates the root cause for the
outage was a contractor laying new fiber for another carrier, damaging
SWBT's fiber. However, it turns out SWBT has *ZERO* route diversity
for this 300 mile route in their network. SWBT has no plans on adding
diversity on this route by either installing new cable, or swapping
or leasing space on a different carrier's system. As a customer of
SWBT, just try to find out about these 'minor' challenges in SWBT's
