A spokesman for Northern Telecom, in a recent telephone conversation,
said that some 20-30 software updates for the DMS100 were necessary to
cure certain problems with passing 212a and V22.bis modem signals
through the switch.  It is unclear at this time if these updates have
any bearing on the outages of the past two days.  According to sources
at Michigan Bell and Northern Telecom, the updates have not been done
to the DMS100 digital switch in the Southfield central office.  They
are reportedly scheduled to be done on June 7th.

Stay tuned...
