5.5.7 Configuring the Trunk Group Table
Use the Trunk Group table to assign trunk groups, profiles and logical telephone numbers
to the gateway's E1/T1 B-channels. Trunk Groups are used for routing IPÆTel calls with
common rules. Channels that are not defined are disabled.
¾ To configure the Trunk Group table, take these 4 steps:
1. Open the ‘Trunk Group Table’ screen (Protocol Management menu > Trunk Group);
the ‘Trunk Group Table’ screen is displayed.
Figure 5-17: Trunk Group Table Screen
2. Configure the Trunk Group according to Table 5-8.
3. Click the Submit button to save your changes.
4. To save the changes so they are available after a power fail, refer to Section 5.9.2 on
page 124.
Table 5-8: Trunk Group Table
Parameter Description
From Trunk Starting physical trunk number (0 to 7).
To Trunk Ending physical trunk number (0 to 7).
Channels
To enable the trunk’s B-channels, you must enter their number in this field.
[n-m] represents a range of channels.
For example, enter [1-24] to specify the channels from 1 to 24.
Note 1: The number of defined channels must not exceed the number of the trunk’s B-
channels (1-24 for T1 spans and 1-31 for E1 spans).
Note 2: To represent all B-channels use a single asterisk instead.
Phone Number In each of the Phone Number fields, enter the first number in an ordered sequence that
is assigned to the range of channels defined in the adjacent ‘Channels’ field.
Note: This field is optional. The logical numbers defined in this field are used when an
incoming PSTN / PBX call doesn’t contain the calling number or called number (the latter
being determined by the parameter ‘ReplaceEmptyDstWithPortNumber’); these numbers
are used to replace them.
These logical numbers are also used for B-channel allocation for IP to Tel calls, if the
trunk group’s ‘Channel Select Mode’ is set to ‘By Phone Number’.
Trunk Group ID In each of the Trunk Group ID fields, enter the trunk group ID (1-99) assigned to the
channels. The same trunk group ID can be used for more than one group of channels.
Trunk group ID is used to define a group of common behavior channels that are used for
routing IP to Tel calls. If an IP to Tel call is assigned to a trunk group, the call is routed to
the channel or channels that correspond to the trunk group ID.
You can configure the Trunk Group Settings table to determine the method in which new
calls are assigned to channels within the trunk groups (refer to Section
5.5.8 on page
83).
Note: You must configure the IP to Trunk Group Routing Table (assigns incoming IP
calls to the appropriate trunk group). If you do not configure the IP to Trunk Group
Routing Table, calls do not complete.
For information on how to configure this table, refer to Section
5.5.5.2 on page 72.
Profile ID Enter the number of the Tel profile that is assigned to the B-channels defined in the
‘Channels’ field.
