1.GeneralIntroduction
The ALK300 series transceiver of VictelGlobal adopts standard
19-inch 2U structure, fully modularized design and optimal design for
heat dissipation. The front panel is equipped with high-speed bus line for
connection between transceivers, the special wiring hole of which
facilitates the installation, test and maintenance and makes the whole unit
tidy. VictelGlobal has been granted the patent for structural design.
The ALK300 series transceiver adopts dual PA design, greatly
reducing the unit temperature, improving the unit stability and prolonging
the unit life. The two PAs can work separately as two PAs and work
altogether as backup for each other.
1.1 Configuration
The digital transceiver is consisted of digital Rx & Tx module,
power supply module, PA module, Carrier Control Module (CCM), hub
board, satellite module and bus line board etc., which are connected via
the bus line board.

1.2 Functions
zRF Transmission
The RF Tx module shall modulate the digitalized audio and
digital/analogue signalling generated by CCM to the RF signal and
then transmit it.
zRF Reception
The RF Rx module shall demodulate the digital/analogue signalling
and audio signals after receiving the wireless signal and then send
them to CCM for procession.
zRx & Tx Information Display
The Rx field intensity and Tx power shall be displayed on the LED in
the front panel. Together with the use of management software, the
detailed parameters of the receiver and transceiver can be acquired.
zLocal Audio
The local audio signal can be monitored via megaphone.
zChannel Cascading
Multiple transceivers can form one base station by connecting the
interface of each transceiver via high-speed bus line. Usually the 1st
channel shall act as the control channel and all the rest channels shall
act as traffic channels, the quantity of which can be increased flexibly
by connecting more transceivers.

2.1 Introduction of Panels & Interfaces
2.1.1FrontPanelofALK300SeriesTransceivers
1— Button of ‘POWER’and Power Supply LED
Press the button ‘POWER’ to power on the transceiver with the
power supply LED turned on. Press the button ‘POWER’ when the
transceiver is under working status to power off the transceiver with the
power supply LED turned off.
2— Button of ‘GATE’ & Rx LED

Press the button ‘GATE’ to switch on the megaphone and the user
shall be able to monitor the audio information received by the receiver.
Press the button ‘GATE’ when the transceiver is under monitoring to
switch off the megaphone. The Rx LED shall be turned on when the

4— Coordination Interface
The NMS shall do various operations to the transceivers via the
coordination interface, including data monitoring, parameter
configuration and software updation, etc.
5— CCM Programing Port
This interface is used for the writing of the programs to the CCM.
The ordinary users do not have access to the interface.
6— Carrier Control Module (CCM)
The CCM controls the work of the whole transceiver and processes
such core work as digital/analogue signaling and audio switch, etc.
7— Hub board
The hub board displays various status information of the transceiver,

including Rx signal field intensity, Tx signal power, transceiver channel
No. and whether the transceiver is undergoing conversation, etc.
The Tx signal power and Rx signal field intensity shall be displayed
at the bottom and top of the board.
The channel No., Tx frequency, PA temperature and power supply
temperature shall be displayed in the middle of board alternately. For
example, the ‘CH.02’, ‘L.050’, ‘C.032’ and ‘C033’ displayed alternately,
means that the channel No. is 2, the Tx frequency is 50, the PA
temperature is 32℃and the power supply temperature is 33℃.
The board shall give corresponding alerts when alarms occur to the
transceiver:
‘-E.F1’ means that the forward power of the PA on the left is too
low;
‘-E.F2’ means that the forward power of the PA on the right is too
low;
‘-E.R1’ means that the reflective power of the PA on the left is too
high;
‘-E.R2’ means that the reflective power of the PA on the right is too
high;
‘-E.C1’means that the temperature of the PA on the left is too high;
‘-E.C2’means that the temperature of the PA on the right is too high;
‘-E.PS’means that the temperature of the power supply is too high.

In the mean time, the LED on the right of the ‘talk’ shall flash twice a
second with red color.
‘service’ LED: constant green means that the audio service of the
transceiver is normal, or it means that the service has been suspended.
‘talk’ LED: it is the conversation LED. The LED shall flash once a
second when the transceiver assigns the 1st time slot for conversation,
flash twice a second when assign the 2nd time slot for conversation, and
shall be on steadily when both the 1st time slot and 2nd time slot are
assigned for conversation at the same time or when it works as analogue
channel. The LED shall be off when the transceiver is not involved in any
conversations.
8— Coding Switch of the Transceiver
The transceiver can realize conversation via wired links by
connecting the transceiver to the wired equipments. The data for wired
conversation shall be fixed to the corresponding channels via hardware.
The two red coding switches are the ones to realize the function. As long
as the channel No. (1~6) is confirmed, just switch the two coding
switches with the same No. to ‘ON’.
9— Bus Line Interface
The bus line interface is used for the connection between
transceivers, and between transceivers and wired equipments, realizing
extension of traffic channels which can be maximum of 12.

10— Bus Line Interface
The bus line interface is used for the connection between
transceivers, and between transceivers and wired equipments, realizing
extension of traffic channels which can be maximum of 12.
11— Second Pulse LED
The second pulse LED shall flash once a second when the second
pulse of the channel is normal, or it shall be off.
12— Ethernet Port
The Ethernet port is controlled independantly by the CCM. It is used
to connect the transceiver to PC or network switch via cable.
13— Side Board Interface
The side board interface is used to connect the side board to the
transceiver. The side board refers to the board on the right of the
transceiver where the ‘red’, ‘yellow’and ‘green’ buttons rely.

2.3 Hopping
2.3.1CodingSwitchoftheTransceiver
There are totally 1-6 pairs of coding switches on the digital

transceiver. The pair of coding switches switched to ‘ON’ decides the
audio channel to be used. Currently, the E1 supports 12 logic audio
channels, that is, 6 physical traffic channels (each physical traffic channel
includes 2 logic channels).
For example, switch the 1st pair of coding switch to ‘ON’ if the
‘channel No.’ set in the NMS is ‘0’, switch the 2nd pair of coding switch
to ‘ON’ if the ‘channel No.’ is ‘2’, switch the 3rd pair of coding switch to
‘ON’ if the ‘channel No.’ is ‘4’ and switch the 4th pair of coding switch to
‘ON’if the ‘channel No.’ is ‘6’.
zWhen the quantity of physical traffic channels is no more than 6,
just refer to the default settings:
The channel addresses are 2, 4, 6, 8, 10…
The 1st pair of coding switch of the channel 0 is switched to ‘ON’;
The 2nd pair of coding switch of the channel 2 is switched to ‘ON’.
For the audio conversation settings of the E1 link module, just refer
to the default ones, that is, the 1st audio interface is for channel 1, and the
2nd audio interface is for channel 2…
zWhen the quantity of physical traffic channels is more than 6 but
the quantity of the audio channels is no more than 6:
For example, there are 8 physical channels with channel addresses: 0,
2, 4, 6, 8, 10, 12, and 14. The channel 0 is set as the digital control
channel, the channel 2 is set as the analogue control channel and all rest 6

channels are set as traffic channels, each of which includes 2 logic
channels.
Configuration:
All the 8 channels are positioned above the base station controller.
The coding switches for channel 0 and channel 2 are OFF, the 1st
pair of coding switch of channel 4 is ON, and the 2nd pair of coding
switch of channel 6 is ON…
2.4 Power On the Equipment
After connecting the power supply wires, switch on the power supply
switch at the back of the transceiver. If the power supply LED is turned
on then it means that the power supply module works well. Then, press
the button ‘POWER’at the front panel to power on the transceiver.
3 NMS Settings
The user can configure the parameters and monitor the working of
the transceiver via NMS, such as the working mode, working frequency
and working status of the transceiver, etc.
