Ring Start Output
A ring generator enable (ground) output is applied to the 48020
Ringing Generator Module and the 49020 Tone Supply Subas-
sembly using P2-11 when an address has been selected. This
output is switched to ground through the open collector of Q1.
The ground enables the ring generator and the ring/ring back
interrupt functions.
The 49018 subassembly is mounted to a 44020 DTMF Decoder
Module n a 440 CMS or TMS single station package. The 44020
module provides power and all input/output connections to the
49018. Fig. 3 shows a typical order wire application.
