CallVisor Adjunct-Switch Application Interface 

■

Generalized Route Selection

GRS supports wideband BCC to identify wideband calls. GRS searches a 
route pattern for a preference that has wideband BCC. Route preferences 
that support wideband BCC also can support other BCCs to allow different 
call types to share the same trunk group.

■

CO Trunk (TTC - Japan) Circuit Pack

This circuit pack cannot perform wideband switching. No member of the 
circuit pack should be a member of a wideband group.

CallVisor Adjunct-Switch Applications Interface (ASAI) links DEFINITY ECS 
and adjunct applications. The interface allows adjunct applications to access 
switch features and supply routing information to the switch. CallVisor ASAI 
improves Automatic Call Distribution (ACD) agents’ call handling efficiency by 
allowing an adjunct to monitor, initiate, control, and terminate calls on the switch. 
The CallVisor ASAI interface may be used for Inbound Call Management (ICM), 
Outbound Call Management (OCM), and office automation/messaging 
applications.

CallVisor ASAI is supported by two transport types. These are:

1. Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) 

transport (CallVisor ASAI-BRI)

2. LAN Gateway Transmission Control Protocol/Internet Protocol transport 

(DEFINITY LAN Gateway).

CallVisor ASAI messages and procedures are based on the ITU-T Q.932 
international standard for supplementary services. The Q.932 Facility Information 
Element (FIE) carries the CallVisor ASAI requests and responses across the 
interface. An application program can access CallVisor ASAI services by 
supporting the ASAI protocol or by using a third-party vendor application 
programming interface (API).

For a simple ASAI configuration example, refer to
