PlanningInstallation Manual 33PAD In and PAD Out ( PAD_VALUE)For each port, use the PAD In and PAD Out fields to record the amount of PAD to be introducedinto the communication between the KX-TDA0480 and the PBX main unit.PAD is a voice line gain/loss function expressed in decibels (dB) which is introduced intocommunications between the KX-TDA0480 and the PBX main unit. This feature is used toemulate the loss normally generated in PSTN network transmission.The following values are provided in the MCS list box.+14dB, +12dB, +10dB, +8dB, +6dB, +4dB, +2dB, 0dB, -2dB, -4dB, -6dB, -8dB, -10dB,-12dB, -14dB, -40dBThe recommended value for the KX-TDA0480 is 0dB since the PBX introduces its ownpadding towards its extensions.In the sample, the PAD In and PAD Out parameters for all ports are configured to the defaultsfor the KX-TDA0480, In = 0dB and Out = 0dB.In a few cases, these settings may need to be adjusted. See Appendix A4 Pad Control andAGC for details. Adjustments of the nature must be performed on a case-by-case basis.DTMF Detect (DTMF)The KX-TDA0480 capable of using of DTMF.When DTMF is enabled, the unit passes digits after a call has been established, the KX-TDA0480 on the originating end detects the DTMF tones, captures them, and packetises themfor TCP transmission to the destination KX-TDA0480 where regeneration occurs.When DTMF is disabled, DTMF is transmitted over the voice path.The available settings include:• Care must be taken to calculate the end-to-end gain/loss when reconfiguring the PAD In andPAD Out parameters since these settings can have a cumulative effect when both areconfigured.No: DTMF will not be detected.Outgoing (Default): DTMF will be detected for outgoing calls.Incoming: DTMF will be detected for incoming calls.Both: DTMF will be detected for incoming and outgoing calls.
