Table 3-50: Trunk Group Table Description
Parameter Description
Module The module type (FXS, FXO, BRI, or PRI) for which you want to define the
Trunk Group.
Note: FXS and FXO modules are applicable only to Mediant 1000.
From Trunk Starting physical Trunk number. The number of listed Trunks depends on the
device's hardware configuration.
Note: Applicable only to PRI and BRI modules.
To Trunk Ending physical Trunk number. The number of listed Trunks depends on the
device's hardware configuration.
Note: Applicable only to PRI and BRI modules.
Channels The device's channels or ports (analog module), or Trunk B-channels (digital
module). To enable the channels, enter the channel numbers. You can enter a
range of channels by using the format [n-m], where n represents the lower
channel number and m the higher channel number, e.g., [1-24] specifies
channels 1 through 24.
Notes:
 The number of defined channels must not exceed the number of the Trunk’s
B-channels.
 To represent all channels, enter a single asterisk (*).
Phone Number Enter the first telephone number that you want to assign to the first channel
defined in the 'Channels' field. Subsequent channels are assigned the next
consecutive phone number.
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 channel behavior 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 (refer to ''Configuring the
Trunk Group Settings'' on page 228) to determine the method in which new
calls are assigned to channels within the Trunk Groups.
Note: You must configure the 'IP to Trunk Group Routing Table' page (refer to
''IP to Trunk Group Routing'' on page 204) to assign incoming IP calls to the
appropriate Trunk Group. If you do not configure the 'IP to Trunk Group Routing
Table', calls do not complete.
Profile ID The Tel profile ID (refer to ''Tel Profile Settings'' on page 214) assigned to the
channels defined in the 'Channels' field.
