Introduction
INTRODUCTION
b-line XT allows the forwarding of telephone calls to analogue and digital Audio interfaces.
The connection to the telephone network can be established either via two analogue 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.

Construction
1 CONSTRUCTION
The functions of b-line XT are implemented in a single unit. The system is designed 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 interface. 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 independent 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
–two independent Echo Cancellers for each line
–two independent AGCs (Automatic Gain Control)
–two independent Expanders
– 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 Audio interfaces (digital: one AES/EBU interface) are available. If the AES/EBU
interface is selected, both channels are multiplexed together (right/left channel). The inputs have separate digital Sample Rate Converters (SRC). For synchronisation with an external clock a clock input and a clock output are available.
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 workplaces (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
1
.
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 ventilation.
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 frequency 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.
1
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 warranty claim.
!
PAGE 20
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 carried 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 functions are indicated on the display. In the middle there are two buttons for navigation (selection upwards/downwards), two buttons for accepting/dropping 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.

3.5 Operating modes of the system
The following figures show the system in the different operating modes and
their respective cablings.
3.5.1 POTS operating mode
The minimal wiring for the operation with an analogue telephone line is pictured in Fig. 4. Via the PHONE Interfaces up to two POTS telephones can be
connected for PRETALK if required.
FIG. 4 MINIMUM WIRING IN POTS OPERATING MODE
The maximum wiring with all options is shown in Fig. 5. The LAN interface
allows the connection with a PC with Talkmaster XT
®
Software. In total,
three PCs with Talkmaster XT
®
Software can access the system. Via the
RS232 interface you can connect two b-line XT Keypads.
ATTENTION Earthing
If the POTS interfaces are in operation, the system must be earthed via earthing screw for EMC reasons. If the earthing is not carried out, the Audio signal
can be faulty on the caller’s side (humming).
ATTENTION Connection of a POTS Telephone
Please note that the PHONE interfaces are implemented as 6-pole Western
sockets. Standard telephones with 4-pole Western connectors must not be
used because otherwise the contacts in the socket will be destroyed.
