1. For Network Source settings, the following options apply:
• DSX/DS1: The module will use the DSX-1 interface for the network source when the module is provisioned
for the T1-OR mode. If the module is provisioned for the T1-NIU mode, the network source will be the DS1
interface. The MUXes will not be used, even if present.
• MUX A: The module will use MUX A as its data source. The module will not switch to MUX B in the case of
a MUX A failure. The EQ jacks can be used as a temporary test point in conjunction with the EQ jack setting
on the loopback/test screen.
• MUX B: The module will use MUX B as its data source. The module will not switch to MUX A in the case of
a MUX B failure. The EQ jacks can be used as a temporary test point in conjunction with the EQ jack setting
on the loopback/test screen.
• Auto MUX: The module will default to MUX A as its data source. In the event of a MUX A failure, the module
will perform a protection switch to MUX B if it is present and in service. The EQ jacks can be used as a
temporary test point in conjunction with the EQ jack setting on the loopback/test screen.
2. The default service state is Out-of-Service Unassigned
• Out-of-Service Unassigned allows the loops to train up but does not connect to the DSX or MUX interface.
• The Out-of-Service Maintenance setting allows active connections to the DSX or MUX interface; however, no
alarms will be generated.
• The In Service setting allows full functioning connections to DSX or MUX interfaces.
