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

[Lelio Fulgenzi]

unfortunately there are no CLECs in the area from what we are aware of. and I'm not sure they would have a different path. I believe it will be copper PRIs right from the telco, but you never know when that might change.

we also have our WAN link - and it might be that our HQ service provider will be able to effectively route 911 calls to the correct PSAP even though it's a different area code.

  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?
