1-4 DMS-100 ringing overview

297-1001-131 Standard 06.01 October 2000

Figure 1-2 Normal versus immediate ringing on 1FR line

The effects of immediate ringing on the power ringing signal differ between

LME and LCE. In LME, when immediate ringing is enabled, the DMS-100

schedules power ringing during the next available time slot in the ringing

portion of the ringing cycle. Ringing is removed at the end of the last time slot

in the ringing portion of the ringing cycle.

For example, in Figure 1-2, "Normal versus immediate ringing on 1FR

line." immediate ringing is enabled on the LME, the ﬁrst power ringing burst

applies at the start of time slot 1 and continues to the end of time slot 3. This

results in a ringing burst truncated to 1.5 s rather than a complete 2-s burst.

In LCE, like LME, when immediate ringing is enabled, the DMS-100

schedules power ringing during the next available time slot in the ringing

portion of the ringing cycle. Ringing is removed when the 2-s burst has

completed.
