Listing Updated:
August 2010

Operating Company:
at&t/SBC/Southwestern Bell

CLLI:
LWRNKSVEDS0

Switch Type:
Alcatel/Lucent 5ESS

Prefixes Served:
(785) 312, 330-1, 505, 691, 748-9, 812-3, 830, 832, 830, 840-3, 864-5

Notes:
This central office originally had two 5XB switches. A 2B ESS was installed in the late 1970s or early 1980s as a temporary measure to make room for a 1A ESS. There was not enough room in the building to accommodate a 1A ESS without adding to the building, which was not an option, but there was room for a 2ESS. One 5XB served 841 and the other served 748, 842 and 843. The 2B ESS was installed so the smaller 5XB could be dismantled to provide space for a 1A ESS. When 841 moved to the 2B ESS, Southwestern Bell also moved 864 to the 2B ESS from the 5XB on the university campus for the KU Centrex. The massive aesthetic radio tower was dictated by the city of Lawrence in the 1986 time frame to allow the addition of space diversity antennae for the DR6-135 digital radio, $1M worth of brick, mortar and I-beams. Today, as you can see, at&t has allowed the Lawrence Chamber of Commerce move into a part of the structure. Also serves Clinton rate center (785-748). Building name is "Vermont"after the street name that it resides on.

 

Manhattan

Listing Updated:
August 2010

Operating Company:
at&t/SBC/Southwestern Bell

CLLI:
DS0: MNHTKSFADS0
RS0: MNHTKSFARS0

RS0: (785) 340

Notes:
Kansas State University is located here. The school has an intense rivalry with Kansas University in Lawrence and it carries over to the residents. This building blends in very nicely with the residential area which it is placed. It is hard to find because it is not in the middle of the business district. This appears to be a new building, as this town has had dial service (step by step) dating back to at least the 1940s. Building name is "Fairchild" after the street name that it resides on.

 

Marysville

Listing Updated:
August 2010

Operating Company:
at&t/SBC/Southwestern Bell

CLLI:
MYVIKSELRS0

Switch Type:
Genband/Nortel RSC

Prefixes Served:
(785) 562, 629

Notes:
SWBT was stuck when it came to putting an automated switch in this city. They had to build a new central office for it and the closest location was a couple of blocks away. The old CO is now owned by a local newspaper. Marysville was the first station west of St. Joseph for the pony express. Building name is "Elm" after the street name that it resides on.

 

Onaga

April 2006

Operating Company:
Blue Valley Telecommunications

CLLI:
(NONE)

Nokia Siemens EWSD remote

Prefixes Served:
(785) 889

Notes:
Prior to 2005, this community was served by Sprint/United Telephone via a Step by Step and later a DMS-100 RSC. Onaga and Westmoreland exchanges were sold to Blue Valley in the late winter/spring of 2005. This is a new building built around 1990 on the same spot as the original Community Dial Office (CDO) step by step when the CO went digital. Red fence in front hides the emergency generator.

CLLI:
OTWAKSMADS0

Switch Type:
Ericsson AXE10

Prefixes Served:

Notes:
This is a beautiful little town halfway between KC and Emporia. A tornado took out the top of the chimney a couple of years ago, hence the different color brick. Building name is "Main" after the street name that it resides on.

Photo 3 is a post card that was for sale on eBay in November 2011 that shows the CO back in the 1950s or 1960s.

at&t/SBC/Southwestern Bell

CLLI:
TPKAKSJCRS1

Notes:
This office is on the edge of the Topeka area. This part of town is sparsely populated and the name Junction tells you that it is a meet office with other LECs in Kansas. It is a gateway for independent LECs and a regen site for fiber systems.
