DigiumTDM400P
The Digium TDM400P is an internal PCI card that offers from one to four analog ports.
Using the FXO daughter modules the analog ports allow you to connect 24 analog
telephone lines provided by a local telephone service provider.
To Configure the Digium TDM400P
1. Follow the steps provided in the Installing Analog PCI Cards
section if your PCI
card is not already physically installed in your Evolution PBX server.
2. Login to Evolution PBX, click the Resources tab then click Phone Lines.
3. In the Setup New Phone Lines field, select Analog-TDM400P and the
configuration window displays.
Note: Most of these settings configure how Evolution PBX will handle incoming
calls. Outbound call settings are configured by clicking the Call Routing tab then
clicking Outbound Dial Map. Available fields:
Setting Description
PCI Slot The PCI slot number refers to the first, second, third, or fourth TDM400P that
you may have installed in your system. It does not refer to the physical slot
that the card occupies on your motherboard. If you have one TDM400P in your
server then this setting can be ignored.
Lines Active The number of telephone lines plugged into the TDM400P (note that the
TDM400P must have one FXO daughter module for each telephone line).
Trunk GRP Defines the trunk group number that Evolution PBX will use to refer to all of the
lines of this TDM400P.
Echo Train Determines the number of milliseconds that will be taken from the beginning of
each call to learn the echo. To eliminate echo begin with the smallest number
and increase until you hear no echo. Use the smallest number you can and do
not combine with the calibrate echo option (see below) and do not use if your
card has hardware echo cancellation.
Volume The transmit and receive volume may be modified for the TDM400P. There are
two fields for Volume Adjust. TX indicates transmit and RX indicates receive.
The transmit volume increases or decreases the volume that a caller from the
PSTN hears and the receive volume increases or decreases the volume that the
internal caller (or Evolution PBX application such as voicemail) hears. Greater
positive numbers increase the volume and greater negative numbers decrease
the volume. Restart in increments of 2 and restart Evolution PBX after each.
Advanced Options Displays the advanced options for this trunk group. The outbound number
translation allows you to modify dialed numbers before they are sent to the
provider (such as automatically adding a 1 before the number). In order to see
the Number Dialed and Translate To option you must directly reference the
trunk group in the outbound dial map. The actual trunk group name must be
referenced and not DEFAULTPROVIDER.
Default Provider Check this box to make this trunk group the default provider for outbound
calls. The default provider is the trunk group (account or line(s) or T-1) that is
used by default when an internal telephone attempts to place an outgoing call.
There can only be one default provider.
Line Number Each analog telephone line that is plugged into the TDM400P is referred to
according to the jack position on the card. Select the destination for each line
that you have plugged in to the TDM400P.
Line Desc. Text that will be added as a prefix to the inbound caller ID field when a call is
received on this number or line. This field can be left blank.
Send Calls To Select the type of destination that you would like to send incoming calls from
each line of the trunk group. Options: Extension, Extension Group, Auto
Attendant, Custom Routing Rules.
Location Choose the actual location or device to send incoming calls from each line of
the trunk group. Note The options that you can choose from in this field change
according to the type of destination that you select in the Send Calls To field.
For example, if you choose Extensions then Evolution PBX will provide all of the
extensions that you have configured as options in the Location field. Also note
that you must configure your extension, extension group, auto attendant, or
custom routing rule before you can select it as an option in the Location field.
