Office Move: PRI isn't going to make deadline

[slambram]

Hi. Office is moving next week, Telco had many months of notice and still couldn't get it done, but i can't say i didn't ecpect that by now.. So the existintg PRI will be staying at the old location for a few weeks. Now, I should have a point-to-point T1 betweenn the old and new offices up any day now. I have a spare IP Office (SOE with 16 vcm), so i'm sure i can get easily get some IP trunks going over the T1 or Interntet. My question, though, is is there a better/simpler way to do this? Ant cheap Cisco modules? Last time it was just a voice T1 not PRI, so I literally twisted it onto the posts of the voice T1 and walked out the door for the last time. It worked perfectly- - instant voice T1 in the new office. I'd be nice to not have to comne back for any equipment. My u8nderstanding is you can't simply crossover PRI's like that? Any creative PRI tricks?

Thanks, -Joe

If the point to point t1 can be used exclusively for extending PRI, then you can simply bridge the exiting PRI to the p2p T1 (they're both DS1 circuits - only difference is the signaling). If p2p T1 is for data, I'd just use what equipment I had on hand. IPO at old site, IPO at new site.

just ask the telco to put a RCF on, buy a few SIP trunk licences, and organise a provider to point the old ISDN to your new SIP trunk.

where are you based?

mforrence, you're saying i can just hardwire the PRI to the point-to-point at the old location, and at the new location i'll have a PRI? (not like i won't be trying it regardless). It would be nice to be able to do this without leaving any equipment behind...

There are Cisco routers that can turn a pri in to sip
If you have two then you can do this.
But if there is a internet connection then you could try to make it a sip trunk.

honey, i fried the IP Office !!!

Sarcasm, it's only one of the services I offer.

I think my idea is better as it requires no visits to remove equipment.

Buy a cheap SIP trunk from where ever.
Buy a few SIP trunk licence channels.

ask the PRI Provider to put a call forward on the numbers to your new SIP trunk.

This requires no extra broadband, routers, or media gateway devices.

Such a forward can cost big bucks!!!

depends on call volume

call forward costs vs Equipement + engineering time costs might be worth it

 

[tlpeter]

Overhere such a forward can cost around €1000 only for the forward.
Then the extra costs per call must be counted too.

[hairlessupportmonkey]

here (UK) you pay per call. its often more than std rate but its sometimes the only option.

 

[hairlessupportmonkey]

mind you in this case, the telco screwed up so they should be footing the bills!

@jzabrams
Yes, if the Point-to-point T1 is truly point to point and has the same framing/line coding (ESF/B8ZS) you should be able to wire the PRI to T1 as a long extension. A bit curious as to why you have p2p t1 and can use it for this task... surely it was installed for a different purpose. Regardless, it will work like a champ. You'll need to cross over the pairs (1 to 4, 2 to 5).

jzabrams,

As long as the P2P DS1 is truly DS1 to both locations it will work. All you have to do is connect the TX to RX, and RX to TX:
Old Loc New Loc
DS1-PRI TX <------DS1-P2P RX <-------------DS1 TX
RX -----------> TX --------------> RX

If you have access to the NIUs, I would put the tie there. That way if the old office space is reoccupied, your circuit won't inadvertently disappear and you go out-of-service, depending how long it takes telco to put in your new PRI.

I have done this arrangement in the past and it works great!
