SMR-C48
The SkyStream SMR-C48 Cable Source Media Router is a data encapsulator that
receives IP, MPEG, or other data through a File In, UDP In, TCP In, or
Ethernet IP Forwarding In logical port. The SMR-C48 sends data out as an
MPEG-2 Transport Stream through the Transport Stream In/Out (TSIO) Out
port.
SMR-C48 Description of System Functionality
Data Piping A packetizer used
for encapsulating either a
proprietary byte protocol or
synchronous bit stream.
The SMR-C48 creates a DVB-compliant MPEG-2 Transport Stream for data
over satellite services.
Industry-leading Performance
■
MPE (Multi-protocol
Encapsulation) DVB
packetization format that enables
a high-speed gateway to an
asymmetric Internet (or private
IP-based) network by
retransmitting IP information in
addition to the payload.
■
High data rate support, up to 48 Mbps over complete (8191) DVB PID range
Supports up to 256-QAM capacities
Reliable Operations
■
High availability platform for strict service uptimes
■
1:1 system redundancy with optional automatic redundancy switch
■
No hard disk—all software runs from flash card, resulting in fewer moving parts
Simple Manageability

Backup/Restore Ghost Image
Set Up Control PC
Prior to starting this procedure, the following steps must be performed on the
control PC (or whichever Windows platform you will use to handle the CD and
store the images):
1 Note down the IP address, system name, and workgroup of the control PC.
2 Share the C: drive of the control PC.
If restoring to the factory image, also perform the following steps:
3 Copy all files in the SMR NT folder (includes SMR431NT.GHO (or similar)
and the application GHOST.EXE) from the SkyStream software CD into the
C:\ folder. Files must be stored in the root C: directory.
4 Save a copy of the hgt.twk file located on the SMR at C:\Winnt\system32
onto the control PC.
Create a Backup of
the SMR
Creating a backup image of the SMR assumes that the SMR has been properly
configured specifically for a user’s application. This image can be created and
stored on any Windows PC (for example, the control PC).
NOTE This procedure should be performed whenever the SMR configuration
has changed significantly.
1 Copy ghost.exe from the SkyStream software CD into the C:\folder on the
control PC. Ensure that there is at least 90 MB of free space on the C:\ folder
of the control PC.
2 Reboot the SMR.
3 Hold down the down-arrow key at the DOS screen when the “Verifying DMI
Pool Data” line appears until the option “Please select the operating system to
start” appears.
4 At “Please Select the operating system to start,” choose DOS.
5 At “MS-DOS 6.22 start up menu,” select “Start SMR with Network support,”
choice 1.
6 Edit the C:\Protocol.ini file for the following parameters:
NOTE This does not affect the IP address of the SMR when booted into NT.
■
Default Gateway
■
IP Address
■
Subnet Mask
7 ALT-F will display file menu. Select Save and Exit.
8 Edit the C:\ SYSTEM.ini file for the following parameter: Workgroup
