A parameter "0" means "infinite time". Therefore, if "0" is included in the parameters, the unit will keep on ringing or being silent from some timing (depends on where "0" is put in these four parameters.)
(Example1 :"100, 100, 0, 0")
  -->"100ms ring, 100ms silent, keep ringing"
(Example2 :"100, 0, 100, 0")
  -->"100ms ring, keep silent" (because the first "0" is effective infinitely)

What is the rule of Tone Timing for Tone settings? [ 2012/09/04 ]
The meaning of four parameters for tone setting is described as.
"on 1, off 1, on 2, off 2" ( on=ringing term, off=silent term).
When it does not contain "0" as a parameter, the setting means as follows.
(Example: "100, 200, 300, 400")
  --> "100msec ring, 200ms silent, 300ms ring, 400ms silent" (and this pattern will be repeated)
A parameter "0" means "infinite time". Therefore, if "0" is included in the parameters, the unit will keep on ringing or being silent from some timing (depends on where "0" is put in these four parameters.)
(Example1 :"100, 100, 0, 0")
  -->"100ms ring, 100ms silent, keep ringing"
(Example2 :"100, 0, 100, 0")
  -->"100ms ring, keep silent" (because the first "0" is effective infinitely)

The displayed caller information is not correct. [ 2012/09/04 ]
Caller information may not be correct depending on your phone system.

The SIP terminal does not ring. [ 2012/09/04 ]

  4. Check the firewall and port forwarding settings on the router.(TGP/UT1xx/UT670/UT248)
  5. Check [Multi Number Settings] in the [Telephone] tab inthe Web user interface.(TGP)
  6. Check [Call Control] for each line in the [Telephone] tab in the Web user interface.(TGP/UT1xx/UT670/UT248)
    – If [Do Not Disturb] is set to [Yes], the base unit or handset does not receive calls.
    – If [Unconditional (Enable Call Forward)] is set to [Yes], the base unit or handset does not receive calls.
    – If [Block Anonymous Call] is set to [Yes], SIP terminal does not receive anonymous calls.
  7. Check that [Do Not Disturb], [Enable Call Forward], and [Block Anonymous Call] are not controlled by your phone system.(TGP/UT1xx/UT670/UT248)
  8. If 3 calls are being handled by the base unit and/or handsets simultaneously, a new call cannot be received and the unit will not ring.(TGP)

I have registered SIP phone to SIP server successfully. I can make a call, but I can not receive a call. [ 2012/09/04 ]
  1. Please check you've turned on some parametes for security related settings as follows:
      SIP_RCV_DET_HEADER_n="Y"
      SIP_DETECT_SSAF_n="Y"

    -Solution:
     Set up appropriate security function of TGP for each usage environment.
     (case1)
    When the user part of the To header in reception INVITE is different from your telephone number, change setting as follows.
      SIP_RCV_DET_HEADER_n="Y" ->"N"
     (case2)
    When the To header in reception INVITE is correct but you cannot receive INVITE, change setting as follows.
      SIP_DETECT_SSAF_n="Y"->"N"
  2. Please check if Phone is installed under NAT environment or not. If yes, please try following procedure.
     Some router may function to close the port which is used for NAT. So, we need to access to router periodically before NAT is closed and information is deleted.
    For accessing to router periodically, please change following setting.
      PORT_PUNCH_INTVL_n="0" -> "20"(example)

What is the rule of Tone Timing for Tone settings? [ 2012/09/04 ]
The meaning of four parameters for tone setting is described as.
"on 1, off 1, on 2, off 2" ( on=ringing term, off=silent term).
When it does not contain "0" as a parameter, the setting means as follows.
(Example: "100, 200, 300, 400")
  --> "100msec ring, 200ms silent, 300ms ring, 400ms silent" (and this pattern will be repeated)
A parameter "0" means "infinite time". Therefore, if "0" is included in the parameters, the unit will keep on ringing or being silent from some timing (depends on where "0" is put in these four parameters.)
(Example1 :"100, 100, 0, 0")
  -->"100ms ring, 100ms silent, keep ringing"
(Example2 :"100, 0, 100, 0")
  -->"100ms ring, keep silent" (because the first "0" is effective infinitely)

What is the rule of Tone Timing for Tone settings? [ 2012/09/04 ]
The meaning of four parameters for tone setting is described as.
"on 1, off 1, on 2, off 2" ( on=ringing term, off=silent term).
When it does not contain "0" as a parameter, the setting means as follows.
(Example: "100, 200, 300, 400")
  --> "100msec ring, 200ms silent, 300ms ring, 400ms silent" (and this pattern will be repeated)
A parameter "0" means "infinite time". Therefore, if "0" is included in the parameters, the unit will keep on ringing or being silent from some timing (depends on where "0" is put in these four parameters.)
(Example1 :"100, 100, 0, 0")
  -->"100ms ring, 100ms silent, keep ringing"
(Example2 :"100, 0, 100, 0")
  -->"100ms ring, keep silent" (because the first "0" is effective infinitely)

*Installation
Is Tree Survey needed to replace previous multi DECT system? [ 2012/09/25 ]
When replacing Panasonic NCP0158 with UDS/UDT at the same position, Site Survey can be skipped. However, we recommend to do Tree Survey.
In the case of replacement from other models, we strongly recommend that I carry out Site Survey and Tree Survey.
Please refer the procedure to Installation Guide or document No.41-001 of technical contents.

Basic procedure of Install for UDS/UDT series? [ 2012/09/07 ]
Why is Tree Survey necessary? [ 2012/09/07 ]
"CS Registration" groups CSs into each air synchronization group and just confirms the transmissive area of reference clock signal from master CS.
Therefore you need to decide the best and fail-over path of clock signal and share this information in all CSs. Additionally, 2nd Master CS is decided at this stage.
Please refer to No.41-015 of technical contents.
