- In Chicago two Illinois Bell CO's are in the same building at 10 S.
- Canal Street. Although some prefixes are wired from Canal East and
- some from Canal West, they can appear anywhere in the service area.
- One company I used to deal with had, in the same office, voice lines
- on the Canal West 312-648 prefix and data lines on the Canal East
- 312-715 prefix. The matter of voice vs. data wasn't the issue either,
- because virtually every voice phone line in Sears Tower is wired from
- Canal East (312-993 or 312-876, mostly), and AT&T's original Redi-
- Access node for downtown Chicago was out of Canal West (312-454).
-
- Are the three CO's at three different locations?
