T1 and no Smartjack?
Jonathan Lemon
and my business location, in order to have internet access at home.
The phone company came out today, and when I got home, I found a new
access box on the front of my house, with what looks like 4 POTS
wiring terminals, 2 pair each, (16 terminals total), but no smartjack.
Not being an expert on this, what do I need to do in order to connect
this up to a CSU/DSU with a RJ-style interface? (Cisco WIC-1DSU-T1)
I'm not sure if I just need a bunch of wires to my own jack, or
something else.
The only labels on the demarc box read:
ckt1 | T1/HDSL x x x x
| DATA/DDS x x x x
ckt2 | T1/HDSL x x x x
| DATA/DDS x x x x
CT1 CR1 CT CR
The 'x's being the terminals.
Sorry if this is a dumb question, I'm just used to getting a smartjack
style interface from the phone co. The service area in question
happens to be Ameritech, if it makes any difference.

I've never, ever seen Ameritech/SBC install a T1 without a Smartjack,
rural suburban or metro. I highly doubt they put the smartjack in
the terminal at the road and are treating this as an extended demarc,
the Minimum Point of Penatration rule would say "just inside".
My best guess is that the outside plant installer setup a drop to the
house and now the hicap installer has to complete the work and will
install a smartjack. Likely, that will involve inside access.

Being that he said he ordered a T1. The missing smartjack should be a clue
that the job is not completed yet. Probably waiting on Hicap to get a person
out to the location to finish the T1 installation and turn up with the local
CO.

But the H in HDSL is a bigger clue.
HDSL is not ADSL or SDSL, it's a more modern implementation of a T1.
You need an HDSL CSU/DSU or whatever it's called to plug into it, or
possibly the telco will come back and provide an adapter that turns
the two HDSL lines (each of which is bidirectional at half a T1 speed)
into something that acts like a conventional T1.

Does the "box" look very much like a regular outdoor telephone NID
except that the "cover" part seems pretty thick?
If the answer is yes, then what you have is an outdoor smartjack
housing. They are made by several manufacturers, Keptel and Hyperedge
being two that I have seen and used.
Inside the "lid" is a 2 slot cage that holds up to two HDSL smartjacks
(more precisely HTU-R or H2TU-R's).
These housings are used in locations where a standard smartjack "shelf"
isn't applicable, like private residences, cell sites and any outdoor
location that needs a weather resistant enclosure.
Your connection would be to the Customer T/R and T1/R1 (CT CR CT1 CR1).
Run a wire from there to a standard RJ48C inside the house where you
want the circuit and plug your CSU into it. Use a decent quality wire
(CAT5 works just fine) or have the telco come and do it (for time and
material no doubt).
Good luck.

interface instead of screw terminals ? Makes me have to go and find the
pin-out.

Interesting. I've been dealing with T1's since 1970 and have never seen
one of external smartjacks. we seldom install T1's in residential dwellings
and where we have, a conventional inside smartjack has been installed
in the basement or garage as the MPOP. And Most commercial buildings
have inside demarc's.
I'm rather surprised SBC would use screw terminals. You're supposed to
be able to specify the interface jack type you want, 8C RJ48 is certainly
the norm. Screw or punch on terminals for T1 interface is very rare.
However, on an outside unit, the idea must be that the customer will
always want to extend the demarc inside but the equipment remains at
the external NID point.
Guess that's why I read this group, I learned something...

Yeah! I took a second look at the box today, and there is a bundle
of wires going into the inside cover, which is about 2" thick. The
box appears to be made by Westell. I had assumed that this was just
a simple container.

Thanks, I'll try wiring this up today.

WILL roll out of his router. There's up to 180vdc on each pair for those vs.
simplex current for a conventional T1.
