Nope. Just a water dish, food dish, litter box, boiler, water heater, chimney, broom & dustpan, water meter. Only thing missing is the breaker box. Some genius put that in the garage, but on an interior finished wall so adding a circuit is a nightmare.

It looks nicer than it really is. That room is maybe four feet wide.

I'm not crazy about the large number of water pipes in there. I have nightmares about one letting go and ruining everything and flooding my apartment.

I have 2-pair CAT3. I can spare some hanks.

I'm holding onto my existing stock of pull boxes and spools...including a spool of shielded 2-pair CAT3 that Ed provided several years ago.

For what it is worth, I've only seen BIX in the COs around here. One of the CLECs uses it to crossconnect from the LEC krone frame to their equipment. Useful when needing to bypass a bad piece of your equipment and you don't want to wait the mandatory 5 day waiting period on a LEC station wiring change. So LEC Krone block -> 25 pr cable with amphenol connector -> BIX block with amphenol connector -> crossconnect wires -> 2nd BIX block -> 25 pr cable to equipment.

LEC uses Krone blocks a lot in the CO. They had a lot of 3-pair Krone blocks that they'd use in homes and businesses. Haven't seen anything larger in the field.

I see the LEC technicians using violet crossconnect wire for NID jumpers and actual crossconnects at binding posts. It is thicker than the wire that I use (general cable blue/wh.blue crossconnect).

When my former employer, Frontier Communications, built out their Congress Street Boston switch site, they had Verizon install a 25-pair cable that ran from the phone/storage room out to a spot underneath the switch room floor. This was intended to be used to bring dial tone out for dialup modems.

At one point I got so sick and tired of dealing with the Krone blocks that Verizon used, I swapped them out for 66 blocks.

Then, when Level(3) bought us out and I moved to their Cambridge MA landing, I found that Verizon had installed a rack mounted frame full of Krones for Level(3) to wire to in order to bring dial tone into the colo cages as needed.

Many of the blocks had broken hinges with the covers dangling...and...the wiring looked atrocious.

Verizon could have done a better job if it had installed 66 blocks instead.

I disliked Krone at first, but once you get the punchdown tool and the pigtail test cable, life is good. Being able to test the circuit *in both directions* without removing wires is awesome. It has some integrated wire management too. (at least in the 300 pair blocks)

Slightly off topic. I was wondering if anyone has run into 70 type coil spring terminal blocks. These were developed by Bell concurrently with 66 blocks in the late 1950's and early 1960's. I only saw them once in a Municipal Building on Staten Island ,NY. They looked like they were a pain to work with,which probably explains why they were discontinued.

So how can you tell if the cross connect wire is type 'F'? I haven't seen it listed on any spools that I have looked at buying

Type F has more twists per foot than standard crossconnect wire. Non F will untwist quite easily. F holds up much better.

Easy. If it doesn't say type F then it isn't type F.
