Introduction
INTRODUCTION
b-line XT allows the forwarding of telephone calls to analogue and digital Au-
dio interfaces.
The connection to the telephone network can be established either via two an-
alogue POTS interfaces or an ISDN interface or optionally via a LAN interface
for Voice-over-IP.
To optimise the caller signal each caller line has implemented its own digital
Echo Canceller (approx. up to 100 msec), AGC (Automatic Gain Control) and
Expander.
The configuration of the system can be made via the Talkmaster XT ®Soft-
ware included in delivery or via the front keypad of the unit. Optionally, up
to two b-line XT Keypads can be connected to operate the telephone hybrid
without a PC. b-line XT also provides four TTL inputs/outputs and two Re-
lays for external control.
With additional Talkmaster XT ®software licences up to three PC worksta-
tions can be implemented, e.g. for Screener - Presenter applications.

SAFETY
Introduction
The unit described has been designed to the latest technical parameters and
complies with all current national and international safety requirements. It
operates on a high level of reliability because of long-term experience in de-
velopment and constant and strict quality control in our company.
In case of normal operation the unit is safe.
However, some potential sources of danger for person, material and optimal
operation remain - especially if daily routine and technical errors coincide.
This manual therefore contains basic safety instructions that must be ob-
served during configuration and operation. It is essential that the user reads
this manual before the system is used and that a current version of the manual
is always kept close to the equipment.
General Safety Requirements
To keep the technically unavoidable residual risk as low as possible, it is ab-
solutely necessary to observe the following rules:
– Transport, storage and operation of the unit must be under the permissible
conditions only.
– Installation, configuration and disassembly must be carried out only by
trained personnel on the basis of the respective documentation.
– The unit must be operated by competent and authorised users only.
– The unit must be operated in good working order only.
– Any conversions or alterations to the unit or to parts of the unit (including
software) must be carried out by trained personnel authorised by the man-
ufacturer.
Any conversions or alterations carried out by other persons lead to a com-
plete exemption of liability.
– Only qualified personnel is authorised to remove or override safety meas-
ures and to carry out the maintenance of the system.
– External software is used at one’s one risk. Use of external software can af-
fect the operation of the system.
– Use only tested and virus-free data carriers.

Conventions
In this manual, the following conventions are used as text markers:
Emphasis: Product names or important terms
LCD Text : Labelling on the front display of the system
PC Text: Labelling in the PC software
TIP
The symbol TIP labels information which facilitates the operation of the sys-
tem in its daily use.
NOTE
The symbol NOTE labels general notes to observe.
ATTENTION The symbol ATTENTION labels very important advice that is absolutely to
observe. In case of non-observance disfunctions and even system errors are
possible.

Construction
1 CONSTRUCTION
The functions of b-line XT are implemented in a single unit. The system is de-
signed for mounting in a half 19" rack (1 U).
Optionally, a dual mounting kit is available (b-line XT Dual 19“ Rack Mount-
ing Kit ID: #YT6006) for installing two b-line XT systems next to each other.

System Description
2 SYSTEM DESCRIPTION
The functional elements of the system are pictured in Fig. 2.
FIG. 2 FUNCTIONAL ELEMENTS OF THE B-LINE XT TELEPHONE HYBRID
2.1 Functionality
b-line XT incorporates two POTS interfaces, an ISDN interface and a LAN in-
terface. The operating mode can be set with the help of the Talkmaster XT ®
Software or the front keypad and display. In each operating mode two inde-
pendent telephone hybrids are available within one system (channel 1 and
channel 2).
The complete signal processing is taken over by a digital signal processor. In
this way the following functions are carried out:
– G.711 Audio encoding and decoding
–twoindependentEcho Cancellers for each line
–twoindependentAGCs (Automatic Gain Control)
–twoindependentExpanders
– control of the complete system (Keypad, Display, Relay, TTL, RS232,
LAN)

PAGE 18
System Description
As ON AIR Audio inputs/outputs two independent analogue or digital Au-
dio interfaces (digital: one AES/EBU interface) are available. If the AES/EBU
interface is selected, both channels are multiplexed together (right/left chan-
nel). The inputs have separate digital Sample Rate Converters (SRC). For syn-
chronisation with an external clock a clock input and a clock output are avail-
able.
Two separate PRETALK interfaces are available in all three operating modes.
Two Telephone Handsets or Headsets (Options: ID: # YT6032/ # YT6033) can
be connected for PRETALK. In the POTS operating mode you can connect two
standard POTS Telephones for dialling and Pretalk.
The advantage of a handset/headset over a POTS Telephone is the possibility
to switch between ON AIR and PRETALK anytime. With a telephone con-
nected to the hybrid, it is only possible after the caller has been switched to
ON AIR and if the telephone has not been hung up.
b-line XT can be operated primarily via the front keypad and the illuminated
display.
The configuration and operation is especially comfortable via the Talkmaster
XT ®Software (see CHAPTER 5) included in delivery, which communicates
with the system via the LAN interface. You can install up to three PC work-
places (additional Talkmaster XT ®Software Licences required, ID:
# YT6038).
Most basic operating functions like accepting a call, dropping a connection
and establishing a connection with a pre-programmed number can be carried
out via four programmable TTL contacts. Two relays are available for status
indication.
Additionally, the operation can be carried out via up to two b-line XT Key-
pads (see CHAPTER 6) which can be connected to the RS232 interface.

3 PUTTING THE SYSTEM INTO OPERATION
3.1 Mounting
With its dimensions (W ×H ×D) of 220 mm ×44,5 mm (1 U) ×220 mm b-line
XT can be either used as desktop device or mounted in a 19 inch rack. Corre-
sponding 19“ mounting brackets are included in delivery. Optionally, a
mounting kit (ID: # YT6006) is available to implement two b-line XT systems
next to each other

.
When mounting the unit please keep in mind that the bending radius of the
cables is always greater than the minimum allowed value.
When the b-line XT Telephone Hybrid is installed, please make sure that
there is sufficient air ventilation: It is recommended to keep a spacing of ca.
3 cm from the openings. In general, the ambient temperature of the system
should be within the range of +5°C and +45°C. These limits are especially to
observe if the system is inserted in a rack. The systems works without venti-
lation.
During operation air humidity must range between 5% and 85%.
3.2 Connection to the mains voltage
The system can be operated with mains voltage in the range of 90 V and 253 V
via the external power supply adapter included in delivery. The mains fre-
quency can range from 45 Hz to 65 Hz. The maximum power consumption is
15W. The rack must be earthed according to the VDE Regulations. This can be
carried out via the earthing screw on the back side of the unit.
The unit does not have a circuit closer and a circuit breaker. After plugging in
the external power supply adapter the unit boots in a few seconds. In standby
mode the level meter/status display is shown on the display.

In this way, you can also combine b-line XT with the products b-line ISDN/POTS and b-line
POTS.
TIP
The system temperature can be indicated on the display ( Menu Status Infor-
mation
(see CHAPTER A1.4, Page 97))
ATTENTION Incorrect ambient temperature and humidity can cause functional defi-
ciencies.
Operation outside the threshold values indicated above leads to a loss of war-
ranty claim.

Putting the system into operation
3.3 Earthing of the system
For EMC reasons an earthing via the earthing screw of the system must be car-
ried out in either case.
3.4 Operating elements on the front side
The system has an illuminated graphical display with a resolution of 160 x 32
Pixels and 21 operating buttons.
On the right next to the display there are two softkeys whose current func-
tions are indicated on the display. In the middle there are two buttons for nav-
igation (selection upwards/downwards), two buttons for accepting/drop-
ping calls as well as an
OK button. The numerical pad supports in addition to
the numericals
0...9 also the ’ * ’and ’ # ’button. For entering text the numerical
pad can also be used as a normal keypad.
The operation is similar to standard mobile phones.
