I think one of the first scans I ever did was of the Abilene switch.

 

http://pastebin.com/XhumiwhJ

 

Don't forget DLLSTXWHCG0. 214-946-9990 is a not in service recording from that switch. Could the guy making that be any more of a good 'ol boy?

 

OKCYOKWICG0

 

That one sounds like a DMS-100 to me.

 

What does the CG0 as opposed to DS0 (Digital Signal 0) stand for? 0 is for 64k lines, at least DS0, That much I think I know, what about CG?

 

DS0 in the context of a CLLI code is actually a little different. A CLLI is read as WWWWXXYYZZZ:

 

W and X are the equipment's city and state as you've already noticed.

 

Y = Building code

Z = Equipment code. For a switch, the first two characters tell you what kind it is, while the last tells you which it is, usually starting with 0 and going up.

 

VS = Video switch (or so I've heard)

GT = Trunk gateway (usually for packet-based media gateways)

CM = Commercial Mobile switch

PS = Packet Switch

DS = Digital Switch

CG = Control Group (Digitally controlled electromechanical switch)

MG = Marker Group (Crossbar)

DG = Decoder Group (Panel)

SG = Selector Group (Step)

Why do all ringing or SIT numbers stay on the line for 3 minutes on 615-650? SIT messages keep in a loop for 3 minutes, numbers that ring out do so in 3 minutes. Does it have anything to do with being an older switch ? (The other 1AESS's I tried out didnt behave like this tho.. )

 

**Edit:

Now I realize other errors and ringouts I tried in 212 behave the same way, except it's a different (far lesser) amount of time that the switch disconnects and I get sent to reorder (but uniform amongst different numbers I dialed). I guess I'm just looking for oddities that aren't there sometimes.The unending looping errors on 616-650 are really cool though and uncommon (for me), usually it's two repeats if any and straight to reorder.

 

Is the blocked call recording Jane Barbe? Also, what tone is it that plays in the AIS that reads the number back? 2200Hz?

 

 

Also, in your scan, what was that 2200Hz signal for on 9843,9833?

Y = Building code

It's my understanding that when GTE cut CAMSWAXXDS1 to 5EAX in the 80s, they left the building code as "XX" "for historic purposes"! (It had previously been Stromberg XY with director.)

As if to cryptically say, "this was an XY but is now a DS1-type system".

EDIT ADD:
For what it's worth, I have prepared a new list of all the known extant 1A systems as a text file from the listings on Telcodata. I have no idea how up to date it is (half of them may have already been cut to DMS for all I know (hopefully not)) but here it is.

scratchytcarrier: You are definitely correct that almost half of the 1/1AESSes have cut to DMS (or MG9k as well)

 

I would recommend looking up on AT&T's regulatory page and VZ's as they upload documents about the migration from 1A to digital.

(Also would recommend to use the "testline" page to cross reference against the documents.)

 

AND to update your list...

 

all of houston's 1AESSes have been removed.

If you want to cut down on that list a bit, this data seems to be from a relatively recent LERG; http://afiler.com/switches/1ae

 

Here's the changes I made, plus some confirmed 1As if anybody wants to take a poke at those;

 

HSTNTXADCG0 - Cutover to MG9K remote off of CS2k
HSTNTXGLCG0 - Cutover to MG9K remote off of CS2k
HSTNTXIDCG0 - Cutover to MG9K remote off of CS2k
HSTNTXWLCG0 - Cutover to MG9K remote off of CS2k
FTWOTXJECG0 - Cutover to MG9k remote off DMS-200
FTWOTXGLCG0 - Cutover to MG9k remote
FTWOTXATCG0 - Cutover to MG9k remote off DMS-200
BLTMMDEDCG0 - Cutover, traffic migrated to CS-2000
RCMDVAHLCG0 - Cutover, traffic migrated to CS-2000
NRFLVAGSCG0 - Cutover, traffic migrated to CS-2000
LGVWTXPLCG0 - Not a 1A

DLLSTXWHCG0 - 1AESS
DLLSTXHACG0 - 1AESS
ELPSTXNECG0 - 1AE(1E?)SS
BUMTTXTECG0 - 1AESS
FTWOTXWACG0 - 1AESS

Okay, here is an updated version based on the listings given above. (Thanks, guys.)

I think it's a better idea to stick the deactivateds/cutovers to a section at the bottom. (Use the cut and paste to move an entry there). I also inserted a status column at far right where you can put your notes.

Here's an update with all the LERG info in it. If it's right, that makes about 26 offices remaining? I'm kinda sleepy right now, so don't take my word for it. Anyway, just for perspective I think there were forty something in 2006.
