Configuring MultiDSP Cards
(MAX TNT, APX 8000)
Introduction to MultiDSP
The MultiDSP card is a highly versatile, digital signal processor (DSP) slot card for
MAX TNT and APX 8000 units.
The following services are supported by the MultiDSP card:
• Data (digital, analog)
• V.110 rate adaption standard for ISDN
• Personal Handyphone System (PHS), supporting PHS Internet Access Forum Standards
(PIAFS) 1.0, 2.0, 2.1
• Voice over IP (VoIP), including real-time fax functionality (MAX TNT only)
The MultiDSP support provided by a particular MultiDSP card or MAX TNT and APX 8000
unit depends on the following factors:
• The type of MultiDSP card(s) installed in the unit
• Software licenses (hash codes) currently downloaded on the unit shelf controller
• MultiDSP card use constraints (See “Card configuration constraints” on page 6-3 for
details.)
Analog modem service is, by default, always enabled. Each additional MultiDSP service has a
software license (hash code) that must be downloaded to the unit shelf controller for the
particular service to be enabled on a MAX TNT or APX 8000 unit. The hash codes enable
different types of calls to be serviced by the same DSP port on the card.
The MultiDSP services currently enabled (licensed) on MAX TNT and APX 8000 units can be
viewed in the Base profile. For details, see the“Configuring a MultiDSP card” on page 6-6.
MAX TNT and APX 8000 units support two types of MultiDSP cards—a 48-port card and a
96-port card. Each MultiDSP card type supports slightly different services. Following are
descriptions of each card.
