Control Lead Descriptions

See Table 7-2, Network, DSX, or PRI Interface LEDs, for descriptions of these leads. See Table 7-3, User Data Port LED (CSU/DSUs Only), to interpret the user data port OK control lead. The LED descriptions and control lead descriptions are the same.

In addition to these LEDs, additional control leads can be monitored through the Display LEDs and Control Leads screen. These indicators show the current state of each control lead and what they indicate when they are highlighted; that is, in the On state. They are described in Table 7-5, Additional Control Leads.
