Requirements
Installing Recorded Announcement Equipment
Access to recorded announcement equipment is provided by an
information outlet. If the recorded announcement equipment is FCC
registered, the switch side of the cross-connect field is connected
directly to the switch cabinet. If the recorded announcement equipment
is not FCC registered, the switch side of the cross-connect field is
connected to a 36A voice coupler. The 36A coupler is mounted in an
auxiliary cabinet, if one is available. If an auxiliary cabinet is not
available, a connectorized wiring block must be locally engineered to
replace the auxiliary cabinet ED-1E443-10 intra-connection panel.
The switch side of the cross-connect field is connected by the T and R
leads to a TN742 or TN769 analog line circuit pack located in a port
carrier. The TN742 or TN769 circuit pack contains eight ports.
Figure 5-13 shows the connections for the Recorded Announcement
feature when the recorded announcement equipment is FCC registered.
