Conditions
[APT + SLT]
•If one telephone goes off-hook while the other is on a call, a three-party call is established. If one user goes
on-hook, the other user continues the call.
•An extension user cannot originate a call from the SLT if the APT is:
–playing background music (BGM)
–receiving a paging announcement over the built-in speaker.
•The SLT will always ring for incoming calls (if its ringer is turned on). It cannot be programmed to not ring.
[DPT + SLT]
•When in the parallel mode, XDP mode of the Super Hybrid port should be turned off through system
programming.
•Whether the SLT rings for incoming calls is programmable.
Ring on: Both telephones ring when a call is received, except for when the digital proprietary telephone
(DPT) is in Hands-free Answerback mode (® 8.1.1 Hands-free Answerback) or voice-calling mode
(Alternate Receiving Ring/Voice) (® 9.1.13 Intercom Call).
Ring off: Only the DPT rings when a call is received, however, the SLT can be used to answer the call.
•Both telephones cannot engage in calls simultaneously. If one telephone goes off-hook while the other is
on a call, the call is switched to the telephone that goes off-hook. Note, however, that the call will not be
switched when the telephone is:
a. Being monitored by another extension (® 3.1.4 Call Monitor).
b. Receiving an Off-hook Call Announcement (OHCA) (® 12.1.3 OHCA (Off-hook Call
Announcement)) or Whisper OHCA (® 20.1.3 Whisper OHCA).
