9.6 Landline Module Testing
The Nomad Landline Module provides an additional option for voice quality testing without
needing the Audio Server to handset uplink data collection and downlink audio sourcing. In the
Landline Module configuration, the mobile end consists of the standard test handset and Spirent ME
unit connected to a laptop which handles downlink data collection and uplink audio sourcing. The
landline end consists of the Nomad Landline Module hardware with analog phone connections as
the communications links and a computer for handling uplink data collection and downlink audio
sourcing.
Figure 9-6 - System Configuration for Landline Module Testing
The Nomad setup and configuration for both the mobile and landline end are identical to the
Remote Unit testing configuration described in Section 9.3. The only difference is that each test call
is made from the handset at the mobile end to the corresponding analog phone line on the Landline
Module. For the best results, Spirent Communications recommends dialing Line 1 using the
handset on Channel 1, Line 2 with Channel 2, etc. Assuming all four channels are available for
testing, up to four Landline Module test calls may be placed simultaneously.
