Installing the queue warning indicator
Issue 3 January 2008 107
The connections for the queue warning indicator are the same as external ringing. An AC
indicator (lamp) such as a 21C49 can be used in a uniform call distribution/direct departmental
calling (UCD/DDC) queue.
The lamp is connected to an information outlet. The media gateway side of the MDF is
connected to an analog line circuit pack located in a port carrier.
●Wire the queue warning indicator to the information outlet as shown in Figure 51: 3-pair
and 4-pair modularity on page 106 and Figure 41: Example adjunct power connectionson
