Table 5-22: Trunk Group Table
Parameter Description
From Trunk
Starting physical trunk number (0 - 7).
To Trunk
Ending physical trunk number (0 - 7).
Note: Applicable only to digital modules.
Channels
Represents the trunk's B-channels.
To enable the trunk's channels, enter the channels number in this field.
[n-m] represents a range of channels. For example, [1-24] specifies channels 1
through 24.
Notes:
 The number of defined channels must not exceed the number of the trunk’s
B-channels (1 - 24 for T1 spans; 1 - 31 for E1 spans).
 To represent all channels, enter a single asterisk (*).
Phone Number
Enter the first number in an ordered sequence that is assigned to the range of
corresponding 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 channel allocation for IP-to-Tel calls if
the trunk group's 'Channel Select Mode' is set to 'By Dest Phone Number'.
Trunk Group ID
The trunk group ID (1-99) assigned to the corresponding 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
'Configuring the Trunk Group Settings' on page 140).
Note: You must configure the 'IP to Trunk Group Routing Table' screen
(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 'IP to Trunk Group Routing'
on page 126.
Profile ID
The Tel profile ID that is assigned to the B-channels defined in the 'Channels'
field.
