atcomsystems.ca/forum Forums Wiring - Telecom Carriers - Trunks & Services T1's, CSU's and DSU's can I move smart jack ?

That's my thought too, just extend it to where you want it. I've extended them several hundred feet with no problems.

thats a thought , no sure about distances though Im guessing it would be 3- 400 feet . (I can measure it this weekend when we pull cable )

how far can I extend it ?



its on a plywood backboard about 24"x24"

so I could just move the whole thing intact

If there is a CSU to regenerate the signal 400 feet isn't out of line. I've moved them 300 and put a hard loop on the end of the 300 feet and run test patterns clean to the hard loop.

I see bill popped in while I was posting, so extending it should work

nice thing is it looks like Ill be taking over service for the guy thats moving into the space , so Ill retain control of the phone equipment /demark in both locations

I went and took a close look today , customer wants to move this week .

circuit is with CLEC time warner , there telling him 21 days or for 800 they can expedite to 14 days .

distance to extend would be in the 700' - 800' will it work over that distance ?

would I gain anything by doubling up on cable pairs ?

That's a long ways to extend a circuit. Are you putting a CSU on it? If so look at the line build out on the CSU to see what it can handle, a CSU regenerates, cleans up, the signal. If the cable is in place and you can just hook it up you could put a hard loop on it and look at the lights on the NIU to see if they indicate errors or sync loss. You would gain a little doubling the pairs, but not enough to make a difference in my opinion. You're better off with a larger gauge than doubling pairs.

I'd find if it's a LEC smart jack or TWTCs. If it's on net then TWTC can beat the 21 days and in our area really don't care if you move their smart jack as long as it doesn't cause problems. I think a call to their service manager and explain that the circuit is being moved within the same facility and not to a new location may expedite the service. That being said there are also jumper options on most NIU cards for length build out. I don't think the customer would want to leave their circuit terminated in another suite. That time frame is going to be tough if you have to rely on the LEC or TWTC to play ball.

I'm a little off on the terminology ., my experience is the lec or clec brings it up and we connect

I'll describe what I have .

my customer is last unit in the blg , verizon terminal is on the far end . 500 feet of cable from demarc on the wall to the terminal (according to the markings on the cable )

they are moving to a smaller unit about halfway down the bldg (so I'm guessing 250')

Ive got two rj48 jacks so can I put one on a couple of pairs at current location then connect two pairs at verizon terminal to the cable going to the new unit

as to equip I am leaving the white box with the cards that verizon installed in place at the old location

there is another white box that the CLEC guy I deal with calls a "connect reach " it breaks out to dial tone via a rj21x 66 block for voice and has a Ethernet port for data

is this what your referring to a CSU?

thats what Ill be moving .

running new cable to the 500' length would be a pain , maybe I could pull something heavier on the 250' leg if that would help

this would be temporary as they will move the circuit to the new location in 21 days or so

obviously they need phone and Internet in the meantime

Sounds like the box the CLEC provided breaks out the channels of the T1 so I'd say it's some type of channel bank with a built in CSU. That's just my guess as I'm not familiar with the equip name. It should have line build out settings to extend the range. If there is any way you can check with them they may even talk you through the line build out settings, they are usually in feet from the NIU.

I'm 99% sure it is the LEC's smart jack. I've never seen a CLEC provide a smart jack here in Florida.

I say try it and see. Pull it one evening and take the CSU/DSU to the new suite. See if you're getting any errors. If you do, put it back and tell the customer he'll have to wait.
