EMG-XFER (Emergency Transfer)
The Emergency Transfer MO monitors the position of the Emergency Transfer
switch(es) on the PPN’s SYSAM circuit pack(s) and 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 (PPN and EPNs) 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 below.
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:
