It houses an RSC hosted by the Kirksville DMS100. This is one of those offices which demonstrates the dramatic change in Southwestern Bell from the 1920s to the 1970s. The original office is on the right and it looks very much like a bank or library building. It had a business office in front and a switch room in the back. When the old step by step switch got replaced in the 1970s it was installed in the large building addition to the left of the original office. The only effort to keep the addition consistent with the original building is the windows.
Kirksville Photo 2	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: KKVLMOMODS0 Switch Type: Ribbon/Genband/Nortel DMS-100/200 Prefixes Served: (660) 626-7, 665, 785 Notes: Kirksville houses a Nortel DMS100 switch which hosts many remotes spread over a large area. I was surprised when I saw these pictures after I had taken them because in one it appears that the radio tower is behind the building in one and in the center of the building in the other. The tower is actually built about 3 feet from the edges at the rear left corner of the building as seen in Photo 1. The remotes it hosts are Lancaster, Downing, Edina, Higbee, Armstrong, Fayette, New Franklin, Boonville and Glasgow.

The large business office window on the right side of the building front was bricked up years ago but you can still discern the brick is of a different shade. Note: The switch in this central office is expected to be replaced with a new switch (Ribbon/Genband G5 packet remote) in February 2013. CLLI code will change to KNNSMOLORPA.
Lancaster	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: LNCSMOGLRS0 Switch Type: Ribbon/Genband/Nortel RSC Prefixes Served: (660) 457 Notes: This office houses a DMS remote hosted by the Kirksville DMS100. This is a very pretty little town in North Central Missouri. This picture was taken in the interval when SBC had not yet bought AT&T and had eschewed signage of any kind.
Marshall	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: MRSHMOGADS0 Switch Type: Ericsson AXE10 Prefixes Served: (660) 236, 831, 886 Notes: It house another Ericsson AXE10 switch which hosts a single remote in Slater, MO.

It started out with the small dark brick portion on the right. That was roughly doubled by the addition of the lighter brick bays to the right and a new roof line. Finally came the huge toll addition and the radio tower in the 1960s.
Sedalia Photo 2	Listing Updated: October 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: SDLIMOTADS0 SDLIMOTARS0 Switch Type: DS0: Ericsson AXE-10 RS0: Ribbon/Genband/Nortel RSC Prefixes Served: DS0: (660) 826-7, 829 RS0: (660) 530 Notes: It is believed that the former EXchange name here was TAylor. This office sits in downtown Sedalia where the annual Missouri state fair is held. Notice the closeup of the the old Southwestern Bell chiseled into the façade of the building. This photo was taken when the inter-company mail truck was there for a delivery. The façade was applied to the building before the addition was built.
Stanberry Photo 2	Listing Updated: August 2013 Operating Company: at&t/SBC/Southwestern Bell CLLI: STNBMOSURS0 Switch Type: Ribbon/Genband/Nortel RSC Prefixes Served: (660) 783 Notes: It is home to a DMS remote hosted by the St. Joseph DMS100. There is not another AT&T wire center northwest of this one because they sold Marysville to Brightspeed/Centurylink several years ago. At the far left of the front view you can see the rear part of an AT&T 2 truck garage. This far north they get so much snow that it is necessary to garage the trucks.  The front view shows clearly the building addition 25 years ago to place the DMS Remote switch. You can see the clear line where the lighter blond brick starts.
