SECTION 1 – STUDIO INTERFACE INSTALLATION
1Series 2101 Studio Interface - INSTALLATION
1.1 Getting Started
If you have not done so already, you should read the material in Part I (Introduction
to the Series 2101 and its components) and Part II (Series 2101 Planning & Design).
In this section we will cover the various input/output connections of the 2101 Studio
Interface and what you need to know to install the system. Later, in section 2, we will
cover the steps necessary to configure the unit for initial operation and test it. Section
3 has a detailed reference of all menus in the Studio Interface.
The Telos Series 2101 Studio Interface mounts in a 2RU high space in a standard 19”
rack. The unit will operate in any environment where the ambient air temperature is
between 0 to 40 degrees Celsius (32 to 104 degrees Fahrenheit). and relative
humidity is between 0 to 98% (non-condensing). The unit will operate on any
commonly available AC mains voltage between 90 and 240 volts 50 – 60 Hz. You
will want to mount the unit in a position convenient for cable access for the T-Link,
Ethernet, and audio connections.
w
IMPORTANT TIP!
Please see Part II Section 1 of this manual for Series 2101 System Design Criteria. We
assume here that you are familiar with the concepts presented there.
You will need to:
•Connect the T-Link circuits from the 2101 Hub
•Connect audio, via either analog or digital (AES/EBU)
•Connect 1 or more Desktop Directors (screener phone/control surfaces)
•Connect to power
•Assign each Studio Interface a unique IP address
•Assign each Studio Interface a unique Host Name (i.e. Studio name)
•Connect to a 10/100Base-T LAN (local area network)
•Configure the hybrids’ audio characteristics for the requirements of your
installation
•Connect and configure optional Telos TWO hybrid (for studios which
require 4 hybrids)

Î8 Desktop Directors (using optional power supplies and expansion
card)
Î2 T-Link connections to the hub(s) (using optional T-Link Studio
Interface I/O)
Î1 dual channel AES/EBU send-to-caller digital mix-minus source
OR
Î2 send-to-caller analog mix-minus source(s)
Î1 dual channel AES/EBU Caller output
AND/OR
Î2 Analog caller outputs
Î1 program on hold analog source
ÎAccessory 2101 extended dual hybrid (reduces maximum number of
Directors to 6)
Note that there are several configuration choices that you will be making in order to
install the system in a given facility. A diagram of the 2101 Studio Interface’s inputs
and outputs follows:

1.2 Installation checklist (Copy this checklist and use it to help organize your installation)
We suggest you look through the rest of section 1 before proceeding. Then work
through this checklist as you prepare to install each 2101 Studio Interface.
Bring cable for T-Link circuit(s) from the location 2101 hub to the location of
the 2101 Studio Interface. This requires 2 pair for each T-Link connection. See
section 1.3.1 for details.
How many mix-minuses (with send-to-caller audio) will be used for this Studio
2 1 Interface? See “Routing” in section 3.3.1 for more on mix-minuses.
ÈÆIf only a single mix-minus will be available, see “Routing” in section 3.3.1.
Bring 1 or 2 mix-minus audio feeds (AES/EBU, or –7 to +4 dBu analog) from
your console to the 2101 Studio Interface.
How many inputs on the console will be used?
2 1
ÈÆIf only a single feed from the 2101 Studio Interface to the console will be
used see “Routing” in section 3.3.1 for information on your options.
Bring 1 or 2 of the Output (Caller) signals from the 2101 Studio Interface to
Èyour console.
Run one of the supplied Desktop Director cables from the 2101 Studio
Interface to each of the locations where the Desktop Directors will be located.
See section 1.3.2.
If more than two Desktop Directors will be used see section 1.3.2.
If any Desktop Director will be more than 250 feet (75 meters) from the Studio
Interface see section 1.3.2.
Run a connection from the 10/100Base-T Ethernet hub to be used for the Series
2101 to the 10Base-T connector of the Studio Interface.
If you will be using any of the 2101 Studio Interface’s remote input/output
options (such as the ringer mute input) to control the unit see section 1.6.1 and
make those connections now.
Proceed to System Programming Checklist in section 2.1.

1.3 Connections to the 2101 Hub and Extended Hybrid (Telos TWO)
w
IMPORTANT!
Unless otherwise indicated the following instructions apply to both the Series 2101 Studio
Interface and the Telos Extended dual hybrid (Telos TWO Hybrid with special 2101
software). Additional information on the Telos TWO is included in the manual shipped
with that product.
1.3.1 Connecting the 2101 Studio Interface to the 2101 Hub (Studio Interface only)
The 2101 Studio Interface uses internal plug-in T-Link module(s) to connect to
the 2101 Hub. These module(s) have a modular jack accessible through each
rear slot, in slots A (or optionally, A& B). This will be a 8 position “RJ-45”
style miniature connector. An amber (yellow) LED next to below this connector
indicates a Loss Of Signal (LOS) and should not be illuminated under normal
circumstances.
The Studio Interface ships with a single module in slot A, if you are building a
redundant system you will need to add a second module (Telos Part # 1701-00048).
Section 4 has information on installing or replacing these modules.
w
IMPORTANT!
Your T- Link connection(s) are in the first 2 Interface slots from the left side of the unit as
viewed from the rear of the unit (slots A, and optionally, B). The RJ- 45 style connectors to
the right side (slots E & F) are for the Desktop Directors.
