Notes:
1. This trunk type is only applicable for APLT through dial applications (EPSCS applications).
2. Connections to an ETN-Main that is not equipped with FP8 issue 3 (yet providing Speed-Calling) should use APLT type-12
trunks (2-way delay /delay). Incoming calls can only reach the attendant via the network LDN(s) e.g., PBX access code plus a
2-, 3-, 4-, or 5-digit number. The single digit "0" will not work.
3. This type of trunk time-out indicates that if no signal is received and its expiration digits are automatically sent for outgoing type
calls, and the trunk is automatically connected for incoming calls. If no signal is received and time-out occurs, then digits are
automatically sent (for outgoing calls), or the trunk is automatically connected (for incoming calls).
4. This trunk type and optional signaling arrangement may be used to build a "Special Access" trunk group. Special Access refers
to a direct connection to a 4 ESS toll switch. A typical application for this trunk type/signaling arrangement is to support
MEGACOM800 DNIS.
