Campbell

Operating Company:
at&t/SBC/Southwestern Bell

CLLI:
CMPBMOCHRSH

Switch Type:
Ericsson AXE 10 Remote

Prefixes Served:
(573) 246

Notes:
This Central Office is located in the Missouri bootheel. This is one of the many SE Missouri offices which are in the New Madrid earthquake zone where the quakes of 1811 & 1812 all exceeded Richter 8.0. It needed reinforcement to survive a quake but it was impossible to reinforce the building itself so an external Steel cage was built around the structure and then attached to the building.

 

Cape Girardeau

Listing Updated:
July 2010

Operating Company:
at&t/SBC/Southwestern Bell

CLLI:
CPGRMOEDDSA

Switch Type:
Alcatel/Lucent 5ESS Host

Prefixes Served:
(573) 331-2, 334-5, 339, 519, 651, 730, 986
(618) 661

Notes:
Also serves McClure, IL (618-661). It is home to a 5ESS switch which hosts the remotes of the “Cape Cluster”. I have shown it here when it carried the “SBC” signage because only a handful of offices ever got this logo deployed on them. This office is also a toll collection center for SE Missouri. The building once sported a radio tower but when the DR6-30-135 radio got turned off in the early 1990s, the tower went too.

 

Cape Girardeau

(AT&T POP)

Listing Updated:
July 2010

Operating Company:
at&t (Long Lines)

CLLI:
None

Switch Type:
None

Prefixes Served:
None

Notes:
A Point of Presence for the AT&T Long Line (long distance) network. At the rear left of this building is one of the old radio repeater huts, the kind with pebbled concrete walls you see along the highways. It was more than doubled in size by the addition of the structure you see in this picture. The building houses regenerator equipment for the span from Hillsboro, MO. to Memphis, TN. Another place you need a guide to find.

 

Cardwell

Listing Updated:

at&t/SBC/Southwestern Bell

CLLI:
CDWLMOOLRSC

Switch Type:
Ericsson AXE Remote

Caruthersville

Listing Updated:
July 2010

Operating Company:
at&t/SBC/Southwestern Bell

CLLI:
CTVLMOEDRSL

Switch Type:
Ericsson AXE Remote

Prefixes Served:
(573) 333

Notes:
This CO is right downtown in a Mississippi river town, less than a quarter of a mile from the river, sitting in the alluvial soil of Southeast Missouri which will transmit an earthquake ground wave extremely well. (Better than it grows cotton?) The building could not be earthquake proofed so, like the New Madrid CO it got an earthquake proof cage built around it and the building was then attached to it. Those large steel panels across the front of the office protect passers by from flying glass if the big one hits and blows out all the glass in the front of the office. Caruthersville is one of the Missouri outstate casino towns too, it is home to a property owned by Isle of Capri casinos.

 

Chaffee

Listing Updated:
July 2010

Operating Company:
at&t/SBC/Southwestern Bell

CLLI:
CHFFMOTURSD

Switch Type:

Prefixes Served:
(573) 887

Notes:
It serves a nice little Southeast Missouri farming town with a 5ESS remote which is part of the “Cape Cluster” hosted by the Cape Girardeau, MO 5ESS. It sits back a couple of streets from the main road through town and is a tough one to find at midnight for work in the maintenance window.

 

Charleston

Listing Updated:
July 2010

Operating Company:
at&t/SBC/Southwestern Bell

CLLI:
CHTNMOMURS2

Switch Type:
Genband/Nortel RSC

Prefixes Served:
(573) 683

Notes:
Yes, it is another river town in cotton country and it too needed the new Madrid earthquake treatment. This work was done in the late 1980s when Dr. Iben Browning was predicting a Richter 8 or worse quake for the new Madrid fault. No steel sheets required for this office because it does not have the huge plate glass windows found in Caruthersville and Hayti. The customers here are served by an RSC hosted by the Sikeston, MO DMS100.

 

Clarksville

Listing Updated:
July 2010

Operating Company:
at&t/SBC/Southwestern Bell

CLLI:

Switch Type:
Genband/Nortel RSC

Prefixes Served:
(573) 242

Notes:
This is a Mississippi river town at lock and dam 24. It houses a Nortel DSC hosted by the Hannibal DMS100. It is easy to drive right past this office because it is situated so far back from 2nd street that you think it is actually a First street address.

(remote switch from Columbia Main)

Prefixes Served:
(no unique prefixes)

Notes:
The small building in front houses a remote switch hosted from the downtown CO. The building addition behind it was added to accommodate Broadband access equipment about 15 years ago, that’s why the soffit and fascia don’t match on the addition.

Photo 2

Listing Updated:
October 2010

Operating Company:
AT&T (Long Lines)

CLLI:
(unknown)

Switch Type:
(none)

Prefixes Served:
None

Notes:
It started life as one of the square brick repeater office shown on the right side of the building. Then a large addition was built behind that and both structures got the tin roof instead of shingles. It appears that the microwave tower is dead because there are no waveguides. It is not obvious but that third building behind the front structure is attached with a small connecting building. Notice the the pre-merger AT&T “deathstar” logo.

Notes:

Notes:
This CO is located in southeast Missouri. It houses an RSC (Remote Switch) hosted by the Sikeston DMS100. This building did not require the severe earthquake reinforcement seen in New Madrid, all it got was the two steel “X” braces added to the front of the office.

Operating Company:
at&t/SBC/Southwestern Bell

Notes:
It houses a 5ESS switch which hosts a few remotes. Park Hills was created in the 1990s as the result of a merger of four towns including Flat River. No one here calls it Park Hills, to us it is still Flat River. This is the biggest city in the lead belt.

Ericsson AXE Remote

Prefixes Served:

(573) 754

Notes:
If you love Mississippi river towns, you will love Lousiana almost more than any other. It is very picturesque, it gives you an easy view of the mighty river from a distance.

MRTNMONIRS2

Switch Type:
Genband/Nortel RSC

Prefixes Served:
(573) 643

Notes:
The building houses a remote switch hosted by the DMS100 in Sikeston, MO. This is one of the river towns in the bootheel but the building is sufficiently robust that it did not require external bracing. I am not sure why AT&T felt it necessary to build a chain link fence around this building and top it with barbed wire but they did.

Switch Type:

Prefixes Served:

Notes:
This is the town the New Madrid fault is named after. The office houses a remote switch hosted by the Sikeston DMS100. In this office the intent was to reinforce the foundation to protect against a future earthquake. It was discovered that the original foundation concrete had deteriorated over time and normal reinforcement was impossible. The Southwestern Bell engineering staff came up with this clever alternative, They built a robust frame around the building and attached the building walls and roof to it!

Notes:
It is a rural office in Southeast Missouri which houses a 5ESS remote switch hosted by the Cape Girardeau switch. Oran is a pleasant little farm town and so it is not surprising to see that the office was a small house downtown which has since been augmented by 2 building additions. The one next to the house was built first, the one in the rear was built for a small ESS switch back in the late 1970s.

Switch Type:

Prefixes Served:
(573) 686, 727, 776, 778, 785

Notes:
It houses a 5ESS switch. You don’t often find a Central Office that has grown so large it fronts on two streets in a town of less than 20,000. This farming community is close to Lake Wappapello and is the county seat for Butler county. The people here are very friendly, cost of living is low and fishing, lake and river, is handy. Photo shows the older part of the building. You just can’t see it all unless you look both at the Vine street entrance (2 story) and the Pine Boulevard entrance (3 story). It’s kind of interesting how Southwestern Bell, in the 1960s stopped even trying to match original brick and architectural styles in these rural offices.

Prefixes Served:

Notes:
A 5 ESS RSM hosted by the Cape Girardeau No 5 ESS. This office nearly got taken out by the Mississippi River flooding in the mid-1990s. It doesn't sit very close to the Mississippi but it is not far from a small tributary, the Big River. That flood brought rapid growth in this small town to a halt when people discovered it was on a hundred year flood plain. This office is one of the many which serves as a fiber optic route repeater point for SBC's interoffice facility network serving southeast Missouri.

Notes:
Another NO. 5ESS RSM hosted by the Eldon, MO No 5 ESS. It serves a tiny farming community east of the Lake of the Ozarks. 30 years ago Southwestern Bell had little use for these rural offices, today they are convenient places to place fiber optic repeaters. In addition, the availability of broadband optical connections has made it possible for sophisticated users who need lots of bandwidth to locate their businesses in these beautiful recreational locales.

Alcatel/Lucent 5ESS Remote

Prefixes Served:

Notes:
The picture of the rear of the building makes clear that the original building was the lower of the 2 structures. The larger structure was built in 2 separate additions which show much more clearly in the rear view. The first addition next to the original structure was for a toll addition in the late 1960s. The final addition was for a small analogue switch in the 1970s which was subsequently replaced by a Remote Switch hosted by the Eldon 5ESS. 2 views are required to understand that the front of the building, where the business office once was, is covered by the first building addition.

Notes:
This office houses an Erricson remote switch hosted by the Mexico AXE10. The cinder block construction is perfect for an office in rural locations where violent spring and summer storms are not unusual. There are no architectural frills on this rural office, it says "Utility" and nothing else. SBC (at&t) always is a good neighbor, see the well groomed lawn and well maintained chain link fence.
