V7122 Gateway User Guide 213Number Manipulation and Routing ParametersTable 44 Number Manipulation and Routing Parametersini File Field NameWeb Parameter Name Valid Range and DescriptionTrunkGroup_x[Trunk Group Table]TrunkGroup_x = T-U/a-b,c,dx = Trunk group ID (1 to 99).T = Starting physical trunk number (0 to 7).U = Ending physical trunk number (0 to 7).a = Starting B-channel (from 1).b = Ending B-channel (up to 31).To represent all B-channels use a single asterisk instead of ‘a’and ‘b’.c = Phone number associated with the first channel (optional).d = Optional Tel Profile ID (1 to 4).For example:TrunkGroup_1 = 0/1-31,1000 (for E1 span).TrunkGroup_1 = 1/1-31,$$,1.TrunkGroup_2 = 2/1-24,3000 (for T1 span).TrunkGroup_1 = 0-7/1-20,1000 (for 8 E1 spans, 20 B-channels).TrunkGroup_1 = 0-3/*,1000 (for 4 E1 spans, all B-channels).Trunk group is the recommended method to configure the gateway's B-channels.An optional Tel Profile ID (1 to 9) can be applied to each groupof B-channels.ChannelList This parameter is obsolete; use instead TrunkGroup_x.DefaultNumber[Default DestinationNumber]Defines the telephone number that the gateway uses if the parameters‘TrunkGroup_x’ or ’ChannelList‘ does not include a phone number. Theparameter is used as a starting number for the list of B-channels comprisingall trunk groups in the gateway.ChannelSelectMode[Channel Select Mode]Defines common rule of port allocation for IP to TEL calls. 0 = By Dest Phone Number - Select the gateway port according to thecalled number (see the note below). 1 = Cyclic Ascending - Select the next available channel in anascending cycle order. Always select the next higher channel number inthe Trunk Group. When the gateway reaches the highest channelnumber in the Trunk Group, it selects the lowest channel number in theTrunk Group and then starts ascending again (default). 2 = Ascending - Select the lowest available channel. Always start at thelowest channel number in the Trunk Group and if that channel is notavailable, select the next higher channel. 3 = Cyclic Descending - Select the next available channel in descendingcycle order. Always select the next lower channel number in the Trunk
