General
The Nera SatLink 1000 and Nera SatLink 1910 are
fully DVB-RCS compliant Indoor Units (IDU) de-
signed for connecting a single user or an end-user
LAN to a DVB-RCS satellite network.
The IDUs are designed for use on desktop. Nera
SatLink 1910 can also be supplied for rack mounting.
The Nera SatLink contains the DVB-S/DVB-RCS
modems, an industry standard IP stack, and Ether-
net interface – enabling connection to the services
offered by a DVB-RCS Hub without any other exter-
nal units or adapters.
The Nera SatLink can be configured with a range of
different Outdoor Units (ODUs).
Key features of the Nera SatLink 1000:
• Up to 4 Mbps IP throughput
• Return link bit rates up to 2 Mbps
• DVB-RCS compliant
- Compliant with version V1.3.1 of the DVB-RCS
standard ETSI EN 301 790
- Supports ATM and MPEG options on return link
- Supports Turbo coding FEC on the return link
• Multicast support
- Enabling of forward link multicast streams to the
LAN via IGMP
- Support for routing LAN multicast streams to
the return link

INTRODUCTION CONT’D
• QoS
-
Supports classification of return link traffic into
different quality of service classes based on IP
addresses, protocol types, DSCP/TOS, and port
numbers of the IP packets to be transmitted
.
• Can be managed from the Hub or from local LAN
via
- Web interface
- Telnet
- SNMP (option)
• Easy to upgrade SW
- By administrative user via TFTP
- From the Hub via TFTP or Multicast
• Industry standard IP stack
- IP, ARP, ICMP, TCP, IGMP, TFTP client, Telnet
server
- DHCP server on the local LAN
- Options for SNMP management, NAT, and
GRE tunnels on the Air Interface.
• Prepared to interface with industry standard LNBs
and transmitters
- Enhanced DiSEqC support enabling very ac-
curate control of the BUC output power when
used together with the integrated power detec-
tor in the Nera SatLink 4033 Transceiver and
Nera SatLink 3000 transmitter.
• Compact design (size of a laptop)
The Nera SatLink 1910 offers the following enhance-
ments compared to Nera SatLink 1000:
• Up to 8 Mbps IP throughput
• Fast frequency hopping on the return link
• Expansion slot for plug-in card
• Extra internal RAM – allows for PEP clients in
future SW versions with support for HTTP pre-
fetch and acceleration of a larger number of TCP
connections
• 100W internal power supply – providing support
for BUCs up to 5W
• 19”-rack model
Important!
Please note that the Satellite interface
configuration and Terminal line up
described later in this manual are man-
datory and must be carried out by a
Nera authorized technician.

General
Configuration of the Nera SatLink Terminal is carried
out from a web browser on a PC connected to the
SatLink Terminal via Ethernet.
The factory default settings for the Nera SatLink
Ethernet are:
• IP address: 192.168.0.1
• Subnet mask: 255.255.255.0
In order to communicate with the Nera SatLink, the
PC used for configuration must be set up with auto-
mated address assignment DHCP (Dynamic Host
Configuration Protocol).
The SatLink configuration may also be carried out
using the PC's Command Line Interface, CLI.
See the User Guide available on the enclosed CD.
Note!
Before powering up the Nera SatLink Terminal for
the first time, ensure that the Tx coaxial cable from
the Nera SatLink Terminal to the ODU is discon-
nected to avoid that incorrect or potentially damag-
ing signals are sent to the satellite.
Connecting the PC
See figures on the following two pages.
Connect the network cable between the RJ45 con-
nector on the PC and Ethernet connector on the
terminal.

STATUS AND CONFIGURATION CONT’D
Status - satellite
Satellite Interface Status
State
Shows "Two-way link established"
during normal operation.
Transmitter
Shows "On" during normal opera-
tion.
Receiver
Shows "On" during normal opera-
tion.
Satellite Receiver Status
State
Receiver state. During normal
operation it shows “Locked”.
Error rate (Viterbi)
Number of errors detected by the
Viterbi decoder during a fixed time
period. A lower number indicates
better signal quality.

Symbol rate
Measured symbol rate for the forward link
Satellite Transmitter Status
State
Transmitter state. During normal operation it shows

Accumulated Burst Corrections
Shows the accumulated frequency correction (in
Hz) and timing correction (in microseconds) for the
transmitted bursts.
Capacity
Shows the terminal’s return link capacity profile and
currently allocated capacity. CRA (Continuous Rate
Assignment), Max RBDC (Rate Based Dynamic
Capacity), and Max VBDC (Volume Based Dynamic
Capacity) are parameters configured from the Gate-
way. CRA (Continuous Rate Assignment) is fixed
capacity allocated to the terminal. The parameters
Max RBDC (Rate Based Dynamic Capacity) and
Max VBDC (Volume Based Dynamic Capacity) set
limitations for the capacity request algorithm in the
terminal.

statistics
IP Packets Statistics
Table that gives IP packet
statistics on the terminal’s
interfaces. There are two
interfaces where statistics data
are collected: LAN (Ethernet)
and DVB (Satellite). For each
interface, the table contains
the number of IP packets and
the number of bytes that were
received, transmitted, and dis-
carded on the given interface.
Forward Link Statistics
Table containing statistics data
on the satellite forward link
(receiver). Data on the forward
link comes on different PIDs
(Packet Identifier), for each
PID there is one row in the ta-
ble. For each PID the following
information is displayed:
• Type
Data type, it can be signal-
ling (for DVB SI tables) or
traffic (for user or manage-
ment traffic, i.e. IP packets)

• MPEG2-TS
The number of MPEG2-TS packets received on
this PID.
• Cont. errors
The number of MPEG2-TS continuity errors de-
tected on this PID.
• Sections/tables
The number of DSM-CC sections (traffic) or DVB
SI tables (signalling) received on this PID.
Return Link Statistics
Table containing statistics data on the satellite return
link (transmitter). Data on the return link is transmit-
ted in bursts. The table contains one row for each
burst type:
• Burst type
Can be CSC (Logon burst), SYNC (Regular Sync),
CB SYNC (Contention Based Sync), TRF MPEG
(MPEG2-TS Traffic burst)
• Channel
The channel ID for the channel this burst type is
transmitted on. Is normally set to 0 for transparent
DVB-RCS systems.
• No. of bursts sent
Number of this kind of bursts transmitted.
