Notes:
9. To be used with CO applications that provide a "party test" signal toward the PBX.
10. This trunk type and optional signaling arrangement may be used to build a "Special Access" trunk group. Although other trunk
group types may be more appropriate, this trunk group signaling arrangement may function to provide trunking facilities for
MEGACOM Service.
