how does a telco call its service people when the phone network isout?

[WNBC tv news]

AT&T wireless subscribers in New York this morning probably cannot make or
receive phone calls due to what the company calls a software upgrade.

The problem likely started at 1:30 a.m. Thursday, according to a service
representative with the phone giant. Smart phones do not appear to be affected
to the same degree as mobile phones.

When AT&T mobile phone users attempt to make a call, the caller likely receives
a display that says the circuit or channel is not available. There is also no
ring tone.

If someone tries to call the user, the call typically goes directly to
voicemail.

An AT&T service representative told NBC New York that this problem appears to
be restricted to phones within New York City. The representative could not
offer a time frame for when the problem would be fixed.
