1. Safety and operating instructions

When assembling, starting-up and adjusting the modules, it is necessary to consider the system specific references in

the manual instruction.

The modules may only be installed and started up by authorized technical personnel.

When assembling the modules into the receiving points, the adherence of the EMC regulations is to be secured.

The assembly and wiring have to be done without voltage.

All active modules may only be operated with the Headend Controller HCB x00 or Bus Extender BEB x00.

The main voltage and the operating voltage of the modules working by DC have to be in complience to the operating

parameters described in the technical data.

With all work the defaults of the DIN EN 50083 have to be considered! Especially the safety

relevant execution of the DIN EN 60728-11[2] is necessary.

3. General

The COFDM modulator AMB 307 is a module of the head end system B-LINE wich is conceived as a complete system for middle-

sized networks.The module converts one (or two, if hierarchical modulation selected) ASI stream(s) into the digital standard

DVB-T. The signal will be transcoded from the ASI transport stream into cable TV channels. All modules will be programmed via

a central control unit (HCB x00) and are working fully independent afterwards. The status of the modules are displayed via LED’s

(see chapter 7.2 “Status LED‘s“).

LINE

The manual instructions of the Headend Controller HCB x00 and the Bus Extender BEB x00 have to be considered!

4. Front view

5. Functional description

The data stream which results from the ASI input is passed to a FIFO. All services of the resulting transport stream which shall be pro-

cessed into the COFDM modulator will be choosen by controling software of the module. The SI and PSI tables affected (i.e. the PAT,

PMT, SDT, EIT) are automatically corrected. From the Headend Controller informations are provides to generate a complete NIT (Net-

work Information Table) into the transport stream. This is required to enable the receiver (such as set-top-box) to tune in automatically.

The changed SI an PSI tables are fed into the COFDM modulator and an IF signal is generated at the output channel. There is a free

choise of frequency in the output channel from 45 to 862 MHz. On the output side, the modulator does not leak to adjacent channels.

So that errors in level can be signalled if the load fluctuates (the red LED will flash and a trap message will be sent), a reference level

is generated. Every time the level for frequency figures are programmed, automatic measurement of the refence level takes place; this

function will, however, not start until 100 seconds have elapsed after start-up of the system. This function can be enabled or disabled

in the main menu.

6. Adjustments

6.1 Adjustment with the Headend Controller

· Adjustment of the addresses at the Bus Extender BEB x00 and at the modules

· Activation of the programming mode on each module by selecting the line (BEB x00) and the module position (01... 15) at the

Headend Controller(HCB x00)

→ yellow LED illuminates until the beginning of the parameter adjustment

· Adjustment of the AMB 307 parameters (see chapter 9) →green LED is switched on

· After the programming the AMB 307 will be automatically switched into the operating mode

→yellow LED flashes shortly/ green LED is switched on

6.2 Adjustment with PC/ laptop

· Prerequisite for the remote programming is an “online-connection” acording the IP standard and an ethernet connection at the

PC/ laptop

· Adjustment of the line/ position addresses at the Bus Extender BEB x00 as well as at the modules

· At the Headend Controller HCB x00 input IP address (default: 192.168.2.80)

· For “direct connection” between a PC and HCB x00 use crossover cable (RJ 45)

· For connection over a hub use a normal straight throught patch cable

· Start-up HTML browser and put in IP address as target address

· If connected correctly the web interface will be opened on the PC/ laptop and a blue LED (LINK) at the HCB x00 will be lit up.

· All adjustments of the modules are specified on the web interface.

6.3 Adjustment with SNMP

· Prerequisite for the SNMP functionality is the use of HCB x00 with enabled SNMP software option CKB 100.

· Supported is SNMP version 1.0 [2].

· Automatic creation of the MIB based on the current head end configuration by the HCB x00.

· For setting and reading out the parameters and is to receive traps from an SNMP management software required.

· Further notes on the SNMP functionality of BLANKOM modules are listed in the SNMP manual (download: www.blankom.de).

The allocation of a logical channel number (LCN) is a service that allocates

a serial number to each TV activated program. If the set-top box supports

this service at the subscriber, the TV programs are offered in the

order established by program numbers. It should be noted that the num-

bering is done separately for HD and SD programs for the respective type

of the box. The simultaneous activation and number allocation for SD pro-

grams in the HD column provides such programs to the appropriate

channel number in the program list for HD boxes.

When request this menu item at first a security query whether it really set

all parameters to the factory default settings pops up.

Affirming the query, all settings made on the EEPROM will be deleted and

replaced by the default settings. The modul will go back to these default

values. Once the setting process is over, there will be automatic return to

the main menu. It takes about one minute.
