Appendix D: Working With Phone Hybrids - Axia Element Installation & User Manual

Appendix D:
One of the advantages of an Element/Livewire stu-
dio is the smooth integration of Telos telephone interface
equipment with the mixing console. Element telephone
control modules let you put the phone controls in front of
the operator and near the associated faders. Mix-minus
is handled naturally and automatically, without the need
for the usual installation and operator contortions. And
each fader channel has its own mix-minus capability, so
you will never run out of busses.
Since advanced Telos telephone interfaces have Eth-
ernet connections, they are easily connected to your
studio network to be controlled by the Element phone
modules. Sophisticated control signaling may then pass
between the two systems without the need for the usual
parallel connections.
But we recognize that not everyone owns a Telos
phone system (even though we wish they did!), so we've
included GPIO capability in Element to control simpler
telephone equipment that does not have a Livewire in-
terface.
This Appendix describes how to configure Element
for use with the Telos Series 2101 and TWOx12 phone
systems. The functions to control these systems via Eth-
ernet were added to Element with software version 1.1.1,
so you must have this software (or later) to use the fea-
tures for these phone hybrids described here.
Telos TWOx12 Talkshow System
Utilizing v.3.28 or later software
The Telos TWOx12 has an Ethernet connection for
control, so it can be tightly integrated with the Element,
using the multi-line phone control module (p/n 2001-
00180). Together, they provide powerful and easy-to-use
on-air phone capabilities.
Working With Phone Hybrids
Installation and Configuration
Note: Your Telos TWOx12 needs to have soft-
ware version 3.28 or later installed. The latest
software is available on the Telos website at www.
telos-systems.com/support/ .
The following proceedure also assumes that
your Call Controller module was either installed
by the factory, or that you have installed it your-
self following the proceedure described in the
"Installing A New Module" section of this manu-
al's Appendix C.
Follow this proceedure to ready your TWOx12 for
use with Element:
1. Connect your TWOx12 to the Axia network using
it's Ethernet port, and assign it an IP address that is
acceptable for use within your network. (Please refer
to the TWOx12 documentation for instructions on
how to configure IP addresses.)
2. If you have not already done so, connect your tele-
phone lines to the TWOx12 and confirm that they are
working by checking the unit's LCD status display.
Confirm with a connected Telos Desktop Director.
3. Connect both TWOx12 audio inputs and outputs
to an Axia Analog Node. You should use only the
ANALOG inputs and outputs for the hybrid audio
interface.
Why use Analog I/O? The use of analog I/O
with TWOx12 is necessary because the unit's
AES input and outputs use only one connector
each (AES left channel for Hybrid 1 and right
channel for Hybrid 2). Due to this configuration,
these channels
thus we must use TWOx12's analog I/O to en-
sure that each hybrid receives its own correct,
unique Mix Minus.
4. Designate an Analog Node output as Program-On-
Hold feed for the TWOx12 and connect it to the
TWOx12's Program-On-Hold input.
5. Using the Audio Node's Source Configuration web
page, enter a text name and channel number for each
