PAD 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 introduced
into 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 into
communications between the KX-TDA0480 and the PBX main unit. This feature is used to
emulate 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, -40dB
The recommended value for the KX-TDA0480 is 0dB since the PBX introduces its own
padding towards its extensions.
In the sample, the PAD In and PAD Out parameters for all ports are configured to the defaults
for the KX-TDA0480, In = 0dB and Out = 0dB.
In a few cases, these settings may need to be adjusted. See Appendix A4 Pad Control and
AGC for details. Adjustments of the nature must be performed on a case-by-case basis.
• Care must be taken to calculate the end-to-end gain/loss when reconfiguring the PAD In and
PAD Out parameters since these settings can have a cumulative effect when both are
configured.
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 them
for 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:
No:
Outgoing (Default):
Incoming:
Both:
