Signaling and call control

The information in this section describes the signaling and call control of E
and M Type I and II trunks. The call is terminated and the trunk released
by a disconnect message sent to the associated unit.

Figure 223 "Signaling orientation for tandem connection between E and
M and CO trunks" (page 666)

shows the trunk signaling orientation for a

tandem connection between E and M and CO trunks.

Figure 226 "Signaling orientation for tandem connection between E and M
and CO trunks" (page 670)

shows the E and M Trunk signaling orientation

for a tandem connection between E and M and CO trunks.

The information in this section describes the signaling and call control
of E and M Type I and II trunks. The call is terminated and the trunk
released by a disconnect message sent to the associated unit.

Figure

231 "Signaling orientation for tandem connection between E and M and
CO trunks" (page 684)

shows the trunk signaling orientation for a tandem

connection between E and M and CO trunks.

E and M Type I signaling

Figure 224 "E and M Type I signaling patterns - originating party release"
(page 668)

shows E and M Type I signaling patterns for incoming and

outgoing calls.

Figure 225 "E and M Type I signaling patterns - originating

party release on a tandem connection" (page 669)

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).
