[cisco-voip] extra analog lines for 911 where a PRI exists -makessense?

[Fred Nielsen]

I partially disagree.  A lot of new PRIs are provisioned over some sort of
fiber mux in many areas these days that at least gets it close, if not
completely run up to, the demarc point.  This provides a different path over
what many 1MBs are still provisioned over.  Also many telco's provision 1MBs
from different equipment in the CO than PRIs.  I have experienced many
situations where T1s are dropped but analog lines remain in service.  
 
That being said, I've also seen my share of the opposite where everything
(including fiber lines) are taken out by accident.  A better bet is to talk
to your carrier about some kind of path diversity for your existing PRIs, or
if unavailable from a single carrier, seek a second PRI from a different
carrier that may be able to offer it.  This all typically costs money or
time, as a second carrier/CLEC by default will tend to provision your PRIs
over the same loop entrance as the ILEC for the area and will want to charge
additional install $ for different loop arrangements.
 
At the end of the day, you need to do some homework to see how your current
T1s are brought in from the CO, and then see what alternatives paths (T1 or
analog) might exist.  Good luck.

NOPE.. If the construction working takes the Telco Copper run out,
everything goes down.

Just wondering if anyone can help me justify ordering a couple of analog
lines for 911 service which will go into the same router and be serviced by
the same local telephone switch and likely be carried over the same path as
the PRIs. I already have two single port PRI cards to protect against single
point of failure of the PRI card. But in the end, if the router goes down,
it's down. 

 

Anyone ever see a PRI port go down but FXO ports stay up?
