R1V6 Release

Major changes brought about by AUDIX R1V6 software and the vintage 7 TN539:

• With the R1V3, R1V4, and R1V5 software releases, only four channels could be simultaneously active.

AUDIX systems with R1V6 software and a vintage 7 TN539 or TN539B ACCE can use all six

networking ports simultaneously (however, System 75, Generic 1, Generic 3, and MERLIN II can still

only access two of the four DCP channels).

NOTE

If a customer is upgrading to R1V5 or R1V6 from an existing network, and the RS-232

channels and/or six simultaneous channels are not required, the existing TN366 or

TN366B can be retained. The new TN539 can replace the old circuit pack while the

cabling to the switch is left intact.

R1V7 Release

Major changes brought about by AUDIX R1V7 software and the TN539B board:

• The new TN539B ACCE board can provide faster throughput than previous networking boards for

networks with heavy trafﬁc.

• The R1V7 software and the TN539B ACCE board permit 56 or 64 Kbps loopback testing; the serving

ofﬁce can send data to an AUDIX port and, if the connection is up, the AUDIX system will echo the

data back to the serving ofﬁce. See Chapter 14, AUDIX Network Testing for details.

• On R1V7 systems, the network turnaround feature can be administered. This option is activated using

the system : translation : machine : audix/amis/call delivery form; it can

be administered on a system-wide or per-machine basis.

— If network connection turnaround is implemented, the local machine will call a remote machine and

do the following: notify the remote system of its updated subscriber information, request updated

subscriber information from the remote system, and send voice mail and updated message status

information to the remote system. Then network connection will then be turned around and the

remaining events will occur: the remote system will request updated subscriber information from

the local system, notify the local system of its updated subscriber information, and send voice mail

and updated message status information to the local system.

— If the network turnaround feature is not implemented, the local machine will call a remote machine

and do the following: notify the remote system of its updated subscriber information, request

updated subscriber information from the remote system, and send voice mail and updated message

status information to the remote system. The call will then be disconnected.

The network turnaround feature reduces system overhead time and long-distance charges by allowing

all of these events to occur with a single call rather than two calls. If cost control from a central point is

not critical, greater efﬁciency can be gained by implementing the network connection turnaround

feature. The connection can only be turned around once during a single call.
