Figure 227 "E and M Type I signaling patterns - originating party release"
(page 671)
shows E and M Type I signaling patterns for incoming and
outgoing calls. Figure 228 "E and M Type I signaling patterns - originating
party release on a tandem connection" (page 672) shows Type I signaling
patterns on a tandem connection where the originating end is senderized
and the route is over a CO/FX/WATS trunk (not applicable to CCSA).
Figure 232 "E and M type signaling patterns - originating party release"
(page 685)
shows E and M Type I signaling patterns for incoming and
outgoing calls. Figure 233 "E and M Type I signaling patterns - originating
party release on a tandem connection" (page 686) shows Type I signaling
patterns on a tandem connection where the originating end is senderized
and the route is over a CO trunk (not applicable to CCSA).
Idle state For E and M signaling, in the idle state the M lead is ground
and the E lead is an open circuit.
For E and M signaling, in the idle state the M lead is ground and the E
lead is an open circuit.
For E and M signaling, in the idle state the M lead is ground and the E
lead is an open circuit.
Outgoing calls Outgoing calls are processed as follows:
• The M lead changes from ground to battery.
