Selecting Span Types
• T1 CAS—select this option to associate all channels on the span to T1 CAS.
• Regular ISDN PRI—select this option to indicate 23B+D ISDN PRI span and to
designate the last channel as the D channel.
• Custom ISDN PRI—select this option only when your PRI D channel is on the last
channel. AltiGen dealers should work with AltiGen Technical Support to configure
this special case.
• Enable Tie Trunk—check this box to enable a tie trunk. Tie trunks must terminate
to a system also configured as a tie trunk.
Note: This option not available when T1 CAS is selected.
