Primary Rate Interface
Nodal/Centrex Express
(Currently not
supported on Inter-Tel
5000 platforms.)
Allows communication between a private branch exchange (PBX) system and a Centrex
system.
Private Line Integration
(Currently not
supported on Inter-Tel
5000 platforms.)
Allows the system to have private lines using individual channels. The D-channel is not
used on the private lines.
Span-Side
Echo Canceller The Span-Side Echo Canceller cancels out echo originating from the trunk, such as echo
from the telco.
Switched Digital
Services
(Currently not
supported on Inter-Tel
5000 platforms.)
Provide ISDN over a single telephone line by combining several B-channels into a single
bit stream. Switched digital service types include H0, H11, Multi-Rate, and NX 64 kbps.
System-Side
Echo Canceller The System-Side Echo Canceller cancels out echo originating from the system, such as
from a single line endpoint or the handset of a digital endpoint.
Two-Stage
Caller Identification
(*ANI*DNIS*) A two-stage address service that provides both the caller’s telephone number and the
dialed number. It combines the ANI and the DNIS features previously described.
User-to-User
Information (UUI)
(Currently not
supported on Inter-Tel
5000 platforms.)
An ISDN service that allows two users to share and manipulate data information over the
D-channel while maintaining a voice connection on a B-channel. For example, both
parties can view the same document, discuss it, edit it and see the changes as they are
made.
Wide Area Automatic
Call Distribution (ACD)
(Currently not
supported on Inter-Tel
5000 platforms.)
Similar to the system ACD feature, this service can distribute calls to provide faster
service. However, Wide Area ACD allows the calls to be sent to other PBXs in the
network.
