EMG-XFER (Emergency Transfer)
Issue 1 June 2005 1137
S8700 | 8710 / S8500
The Emergency Transfer MO monitors the position of the Emergency Transfer switch(es) on the
EPNs’ Maintenance circuit packs. It does not monitor whether the system is actually in
Emergency Transfer.
Emergency Transfer (ET) provides the ability to connect designated analog phones to CO
trunks when the switch cannot provide minimal phone service. Each EPN’s cabinet has its own
ET capability, and there is one EMG-XFER MO for each cabinet or stack of single-carrier
cabinets.
ET is controlled either automatically by the system, or manually, depending on the setting of the
ET switches as described in the following section.
Emergency Transfer Status
The status cabinet UU command shows the location of the ET switches and the current
status of ET in the designated cabinet as follows:
