When Michigan Bell first installed a new Northern Telecom switch in Southfield (major suburban office and commercial area) it was quite common for subscribers to wait several minutes before receiving a dialtone. Lack of response to call forwarding requests and inconsistencies in how many digits are dialed before a recording or reorder tone could also result from a switch that isn't responding fast enough. The variations in recordings could be caused by programming mistakes. Michigan Bell ultimately had to upgrade the switch as well as correct whatever programming bugs were present. It took many months before it stabilized.
