Administrator's Guide for Avaya Communication Manager

Usage
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.
DIOD trunks are two-way trunks that transmit dialed digits in both directions. In
North America, use tie trunks for applications that require two-way transmission
of dialed digits. Allows Inband ANI.
Digital Multiplexed Interface – Bit-Oriented Signaling (DMI-BOS) trunks allow
communication with systems using DMI-BOS protocol. DMI-BOS trunks allow
inband ANI.
An FX trunk is essentially a CO trunk that connects your server running
Communication Manager directly to a central office outside your local exchange
area. Use FX trunks to reduce long distance charges if your organization averages
a high volume of long-distance calls to a specific area code.
Use ISDN trunks when you need digital trunks that can integrate voice, data, and
video signals and provide the bandwidth needed for applications such as
high-speed data transfer and video conferencing. ISDN trunks can also efficiently
combine multiple services on one trunk group.
Use ISDN for Network Call Transfer. For more information, see Avaya
MultiVantage™ Call Center Software Release 11 — Network Call Redirection.
You cannot enter isdn unless the
both have been enabled on the System-Parameters Customer-Options screen.
Release Link trunks work with Centralized Attendant Service in a private network.
Use SIP trunks to connect a server running Communication Manager to a
SIP service provider's server or switch.
Tandem trunks connect tandem nodes in a private network. Tandem trunks allow
inband ANI.
Use tie trunks to connect a server running Communication Manager to a central
office or to another server or switch in a private network. Tie trunks transmit
dialed digits with both outgoing and incoming calls, and allow inband ANI.
Use WATS trunks to reduce long-distance bills when your organization regularly
places many calls to a specific geographical area in North America. Outgoing
WATS service allows calls to certain areas ("WATS bands") for a flat monthly
charge. Incoming WATS trunks allow you to offer toll-free calling to customers
and employees.
