Chapter 1: Overview
Call Management Features
Dynamic Call Routing.
Tenor DX
’s intelligent call routing capabilities are state-of-the-art. The unit
automatically detects and supports three call types: voice, fax, and modem.
Tenor DX
will first identify the call origination site—trunk circuit, line circuit, or IP routing group
—and then route the call according to any parameters you have configured in the routing database.
Each call may be routed via circuit switched path between any two circuit groups, or compressed
and transported via VoIP when connecting to an IP routing group. Trunk circuits are those that typi-
cally connect to another circuit switched network such as the PSTN. Line circuits typically connect
to a termination device on the user premises, such as a PBX.
Trunk Group Support.
The
Tenor DX
supports trunk groups, which are groups of T1 or E1 chan-
nels used to connect the Tenor to other carriers (such as local telephone company) or to PBX equip-
ment used for circuit aggregation.
Public/Private Dial Plan Support.
The
Tenor DX
supports public and private dial plans. A public
dial plan includes numbers which conform to the international dialing plan (E.164) of a country
code + city/area code + local number. For a public dial plan, you can define the numbering plan
structure for the
Tenor DX
to use for outgoing calls.
A private dial plan does not conform to a public dialing plan (i.e., 3 digit dialing plan); through the
Tenor DX
you are able to configure the unique pattern/dialing plan structure, including number
length.
You are able to configure which dial plan to use for incoming and outgoing calls, including whether
other options such as hop-off calls, will use a public or private dial plan.
User Programmable Dial Plan Support.
The User Programmable Dial Plan Support (UPDP)
enables the Tenor to identify a completely customizable set of digit sequences, such as Local,
National, International or Private Numbers.
PassThrough support for certain call types.
Certain call types can be directly routed to a trunk
circuit, without going IP. There are several routing tables you can configure via the
Configuration
Manager
to adjust how the
Tenor DX
unit routes these types of “pass through” numbers. For exam-
ple, you may want to configure 911 as a “bypass number”, which means that all 911 calls coming
into
Tenor DX
from the line circuit will be routed directly to a Trunk circuit presumably connected
to a PSTN. Bypass calls are never routed over IP.
Hop-off PBX Calls.
Hop-off numbers are phone number patterns for calls to be routed out through
trunks. They are entered in a Hop-off Number Directory and associated with trunks where matching
calls should be sent.
Tenor DX
supports those hop-off PBX calls where the destination
Tenor DX
is programmed to route
the call to the PSTN via Trunk Circuit. (A hop-off PBX call is a toll call which hops through a pri-
vate network to reduce or eliminate the toll charge.) The destination
Tenor DX
unit is configured
with the phone numbers to be “supported” for this feature.
