DBS-2.3/9.2-300 DBS Manual - Revised April 2000 5-17
• If UNA operates over the paging system, the Audio Output of CN4
provides the Audio Ringback sound to be heard over the paging system
when a trunk rings UNA.
• If UNA operates over the paging system, the UNA ringing will always
takes precedence over paging. When a page is interrupted in progress, the
pager must hang up and wait until after UNA ringing ends to reinstate the
page.
• If UNA rings over the paging system, set the Ring Patterns for UNA
Terminals (M, C, & B) to continuous ring burst (FF1 2# 4# 1# 1#). This
sets the contacts to remain continuously activated during the UNA ring
broadcast.
External Ringer (UNA Device)
Guidelines
• An external ringer device can be used to alert users when Universal Night
Answer (UNA) calls come in.
• The external ringer device is not provided with the DBS. It must be
purchased separately.
• UNA calls can also be set to ring over an external paging system. See
“Paging” on page 5-14 for more information. This alternate connection is
preferred when both paging and UNA are required.
• The contact rating for the “C” and “M” terminals is 30V DC, 1 amp
(maximum).
