Configuring MAXDAX
If the outbound call originates from a terminal adapter connected to a Host/BRI or BRI/LT
port, the call originates from the slot and port of the Host/BRI or BRI/LT card.
If the outbound call originates from a terminal server user dialing out through a digital modem,
the digital modem slot is the source of the call. (No matter where the call originates, if it goes
out through a digital modem, the digital modem slot is the source of the call.)
When the MAX unit receives an outbound call, it evaluates the slot and port specifications as
part of identifying the channels available for placing the call:
• If you set the slot and port specifications for a channel to zero (the default), the channel is
available for all outbound calls for which the Ch N TrnkGrp setting specifies the trunk
group assigned to the channel.
• If the slot is nonzero and the port is zero, the channel is available to outbound calls
originating from that slot.
• If you specify nonzero settings for both the slot and port numbers, the channel is available
only to outbound calls originating from that port.
Configuring MAXDAX
With MAXDAX enabled, on a MAX 6000 unit or a MAX 3000, you can route incoming
switched calls from inband T1, T1 PRI, or E1 PRI lines to specific outgoing channels on the
same or different inband T1, T1 PRI or E1 PRI lines. The unit selects outgoing channels on the
basis of parameters you configure for incoming channels.
Introduction
MAXDAX broadens the unit’s call-routing functionality by enabling you to route calls to
outgoing PRI lines.
A MAX unit can be configured to route incoming calls to inband T1 lines by means of either
T1 Drop and Insert or PRI-T1 conversion. With T1 Drop and Insert, the unit sends any calls
received on specifically configured channels of an inband T1 to another inband T1 that
connects to a PBX. With PRI-T1 conversion, the unit sends any voice calls received on
channels of a PRI line to an inband T1 line that connects to a PBX.
T1 Drop and Insert and PRI-T1 are both acceptable call-routing solutions, provided that you
are able to dedicate specific channels to the features and that you connect the MAX unit to a
PBX via an inband T1 line. MAXDAX retains both options, but broadens the unit’s
call-routing functionality by enabling you to route calls to outgoing PRI lines.
How the MAX determines outbound call routing
Basically, MAXDAX performs one function. When a MAX unit with MAXDAX enabled
receives a call from any PRI line, it routes that call to the same (or a different) PRI line. The
unit bases its routing decision on one of the following algorithms:
• Direct mapping—The unit routes a call received on a specified channel to a channel
assigned to the configured destination channel-group. The called number on the incoming
call is used as the calling number on the outgoing call.
