Usage
Use access trunks to connect satellite media servers or
switches to the main switch in Electronic Tandem
Networks (ETN). Access trunks do not carry traveling
class marks (TCM) and thus allow satellite callers
unrestricted access to out-dial trunks on the main
server. Allows Inband ANI.
Advanced Private Line Termination (APLT) trunks are
used in private networks. APLT trunks allow inband ANI.
CAMA trunks route emergency calls to the local
community's Enhanced 911 systems.
CO trunks typically connect Communication Manager to
the local central office, but they can also connect
adjuncts such as external paging systems and data
modules.
Use CPE trunks to connect adjuncts, such as paging
systems and announcement or music sources, to the
server running Communication Manager.
Use DID trunks when you want people calling your
organization to dial individual users directly without
going through an attendant or some other central point.
Allows Inband ANI.
