Ring Cadence - Viking PA-250-IP Product Manual

18. Inbound Call Mode
The Inbound Call Mode determines how the PA-250-IP handles incoming SIP calls. One option is to generate a loud
ring sound. The PA-250-IP can also auto answer the call, to allow SIP paging or remote control of the relay. The
"secure" option for auto answer require the callers to dial the access code in order to transmit a page.
Factory Setting: Auto Answer
Disabled – Inbound SIP calls are not allowed.
Auto Answer – Inbound SIP calls are auto answered on the first ring and can page over the audio outputs.
Auto Answer Secure – Inbound SIP calls are auto answered and the caller must dial the access code in order to
make a page.
Ring: In the "Ring" mode the unit will not automatically answer an incoming SIP call but will output a loud ring signal
in a factory programmed 2 seconds on, 4 seconds off ring pattern (pattern / cadence is selectable).

19. Ring Cadence

When the PA-250-IP is set to loud ring on incoming SIP calls, you can select the ring cadence of the loud ring sound.
It can be programmed to one of four different cadences. Factory Setting: Normal Ring
Normal Ring
(single ring: 2 seconds ON, 4 seconds OFF)
Double Ring
(double ring: 1 second ON, 0.5 second OFF, 1 second ON, 3.5 seconds OFF)
Short-Short-Long
(triple ring: 0.5 second ON, 0.5 second OFF, 0.5 second ON, 0.5 second OFF, 1 second ON, 3 seconds OFF)

20. LED Mode
The "Page / Status" LED on the PA-250-IP can be programmed to one of three different modes.
Factory Setting: Paging Mode
OFF Mode: In this mode the LED will not light during normal operation. It will only light (blink) if it cannot register with
the programmed SIP server or while manually resetting all network parameters to factory default.
On Mode: The LED will remain ON when the unit is powered and registered. The LED will flash if registration is lost
and alarm is active.
Paging Mode: The LED will remain OFF in the idle state, light steady when the page is active, then turn OFF when
the call is completed. The LED will also light steady during Multicast paging.
21. DTMF Regeneration
When DTMF Regeneration is Enabled, any touch tones entered by the caller (in band or out of band) will be passed
along to the line out and speaker out. These tones are used by a zone controller or external amplifier to choose which
zone to send the page audio to. Factory Setting: Disabled
22. Pre Page Tone
When enabled, a short beep will be heard prior to SIP or standard Multicast paging audio. The volume of the Pre Page
Alert Tone will match the volume setting of the SIP or standard Multicast page. Factory Setting: Enabled
