The S0 lines connected to the IA12 adaptor may be Point to Point (that supports
the connection of 1 device only) or Point to Multi-Point (that supports the
connection of upto 8 distinct devices). Furthermore, as far as the numbering
scheme is concerned, DDI (Direct Dialing In) may be active on Point to Point lines,
or MSN (Multiple Subscriber Numbering) may be active on Point to Multi-Point
lines. These settings are simply managed by the system software.
The IA12 ISDN Adaptor also supports the following Euro-ISDN features, provided
that the user has the subscription to the network, if necessary :
•
Calling Line Identification Presentation (CLIP)
•
Calling Line Identification Restriction (CLIR)
•
Connected Line Identification Presentation (COLP)
•
Connected Line Identification Restriction (COLR)
•
Advice of Charge at Call Setup (AOC_S)
•
Advice of Charge During Call (AOC_D)
•
Advice of Charge at the End of Call (AOC_E)
The IA12 ISDN Adaptor is capable of matching either “Speech” or “3.1 KHz Audio”
bearer capabilities for outgoing calls as well.
By way of the OP48(-H) or LT48(-H) telephones, several ISDN network messages
including the number of the calling party and call charge information can be
monitored. These network messages are also transferred to the CRL accessories.
Neither MS48 system nor IA12 ISDN Adaptor has internal S0 ports, so it is not
possible to connect an ISDN terminal to the extensions of MS48 system. However,
it is possible to connect another ISDN terminal in parallel with the IA12 ISDN
Adaptor in the Point to Multi-Point lines with MSN facility.
The dimensions of IA12 are 10 cm x 21 cm x 7 cm and the weight is 0.9 kg.
The dimensions of EXP-IA12 are 9 cm x 8 cm.
