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

[Voll, Scott]

if dial tone dies we would send out a message saying so.....  if they
needed 911 everyone would just whip out there cell phones.    For just
normal phone service we just route out a different location.

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?
