Pass-Thru - AT&T MERLIN LEGEND Release 3.0 System Programming Manual

Using SPM

Pass-Thru

The Pass-Thru option allows qualified service personnel to administer IS II/III
applications on a remote PC. It permits you to establish a remote connection
with the control unit to which the IS II/III PC is directly connected. Figure 2–7
illustrates the relationship of the SPM PC, the communications system control
unit, and the IS II/III PC.
IS II/III PC
Figure 2-7. Pass-Thru
A Pass-Thru request must be initiated at a DOS PC. It is not available from a
UNIX System PC; that is, Pass-Thru cannot be established between two IS II/III
PCs. The local admin PC must be in an idle state.
A Pass-Thru request to a locally connected IS II/III system causes the modem to
fall back to 1200 bps if the speed is set to 2400 bps and the modem call to the
control unit is at 1200 bps. If necessary, the communication system will adjust
its speed to that of the local SPM PC.
Once the Pass-Thru connection is established, you can program in any of the
following IS 11/111 applications from your SPM PC:
AUDIX Voice Power™
Call Accounting System
Fax Attendant System
