Onsite and Remote Programming 37
PC-based SPM programming through a modem is performed either onsite or from
a remote location. In both cases, the modem built into the control unit is used.
Dialing
j
connects to the control unit modem’s extension jack. Reach the
built-in modem for remote programming in any of the following ways:
■ Call the system on a remote-access line and enter a barrier code (if
needed), and then dial the code for the control unit’s built-in modem (
)
■ Call the system on a regular line and ask the system operator to transfer
the call to the control unit’s built-in modem (
)
■ Call the remote PC with SPM from a telephone on the system, then
transfer the call to the control unit’s built-in modem (
)
Remote programming allows technicians to run diagnostic tests and to display
information needed to maintain the system. It is also used by Lucent Technologies
technical support organizations for installation and maintenance support.
Remote system programming overrides onsite system programming unless an
onsite backup or restore procedure is taking place. If onsite system programming
is being performed when a remote connection is attempted, the system sends a
message to the programmer that a remote connection has been established and
the current onsite programming session is terminated.
If remote system programming is to be done over loop-start lines, the lines should
be set to reliable disconnect. Otherwise, a line could be seized indefinitely.
