34 Installation Manual
As a general rule it is best to avoid duplicating detection on two communicating KX-TDA0480.
This can be accomplished by always selecting the DTMF detect Outgoing parameter when
using DTMF regeneration.
AGC (Automatic Gain Control)
For each port, record the AGC function levels to be used if this feature is to be enabled.
The AGC (Automatic Gain Control) feature operates at the PAD In side of the unit. If this
feature is to be enabled, the allowed values are recorded in dBm in the range of +3 to -60 dBm.
It is recommended that the PAD In value be set to 0 dBm when AGC is enabled.
The default configuration is for AGC disabled.
Protocol Type (IPROT)
Set a type of the ISDN Layer 3 signal protocol, or a call control signal. Only QSIG is supported.
Hunt Pattern
Use the Hunt Pattern section of the Worksheet to record information how called numbers are
processed through the PBX main unit.
The Hunt Pattern defines which Trunk Group will be accessed when a call is processed and
how the call will be routed through the PBX main unit.
Destination numbers always consist of one or more PBX Codes. Each Trunk Group defined in
the Trunk Data folder can be associated with a PBX Code. When there are two or more Trunk
Groups defined for a single KX-TDA0480, grouped ports can be associated with more than one
PBX by configuring them with the appropriate PBX Codes. Conversely, the Trunk Groups of
several units can be configured with the same PBX Code.
When a Trunk Group is associated with a PBX Code (Destination number), it is then associated
with Hunt Pattern Number (1 or 2). The Hunt Pattern number is used to configure the Trunk
Priority Feature discussed in the next topic.
From 1 to 2 Hunt Patterns can be defined (e.g., A pattern for each Trunk Group that has been
defined for the unit). The relationship between ports, Trunk Groups, Hunt Patterns and PBX
Codes is:
Per Unit Minimum Maximum
Ports 1 2
Trunk Groups 1 2
Hunt Patterns 1 2
Destination No. 1 128
