SAM-MT 400 is an SNMP enabled DVB-H, DVB-T, DVB-S/S2, DVB-C monitoring probe, which covers SNMP based monitoring of all important parameters on all technical layers. It covers:
- RF
- Transport/MPEG2
- MPE
- IP / UDP / RTP / SDP
- FLUTE
- ESG
- EPG
- DVB Subtitling
- Teletext
- Audio/Video
- Conditional Access
This rack mountable 19" device (1 RU) is suited for monitoring DVB-H, DVB-T, DVB-S/-S2, DVB-C unattended at 24/7:
- on-site - directly at the transmitter via ASI, RF or IP interface
- off-site - remotely in the field via RF interface
- anywhere - via IP interface
Up to
eight DVB-H, DVB-T, DVB-S/-S2, DVB-C multiplexes and all programs therein can be monitored
continuously and simultaneously on all technical layers of the broadcast in real-time.
SAM-MT 400 is the most comprehensive SNMP based monitoring probe available for DVB-H, DVB-T, DVB-S/-S2, DVB-C. It provides outstanding monitoring features on all technical layers and monitors in-depth down to sub-feature-level.
Key Attributes:
- supports detailed DVB-H, DVB-T, DVB-S/-S2, DVB-C monitoring on all technical layers - see the Feature Matrix and compare by yourself!
- provides outstanding monitoring features and a comprehensive SNMP MIB including almost 800(!) SNMP operations and TRAPs
- support of SNMPv2 GET, GET NEXT, GET BULK, SET and TRAP
- individual configuration of error and warning thresholds
- access to the probe via SNMP and via RDP (comfortable remote desktop GUI)
- automatically taking TS snapshots if configured error thresholds get exceeded for later in-depth analysis of reported problems
- comprehensive logging capabilities
- for the operator a very comfortable SNMP client is available for both administration and status visualization of all probes in the network (also in a geographical map)
- monitors continuously up to 8 multiplexes on all transmission layers simultaneously in real-time
- very detailed configuration possibilities in order to fit also complex monitoring requirements
- capable of unattended operation at 24/7
- compact design, less rack space (1 rack unit only)
SAM-MT 400 provides a comprehensive SNMP MIB consisting of about
800(!) SNMP operations and TRAPs.
It further fully supports SNMP tables and uses this capability to provide "sub-feature monitoring", i.e. it provides additional monitoring details.
For example, in ETSI TR 101290 a priority one check of the timing of all contained PMTs is required. If one PMT timing is out of range then the aggregated PMT monitoring result is "error". So if one PMT is out of range, in other monitoring solutions there is usually no information available anymore, whether all other PMTs are within the allowed range or not, only an error gets signaled in those solutions.
However, the SAM-MT 400 provides a table listing all information about all table entries (such as the PMTs in the example) separately. So the operator can analyze quickly whether e.g. the "PMT Error" affects the entire multiplex or only a single PMT.
Moreover, SAM-MT 400 even allows to exclude a particular table entry (such as a particular PMT in the example) from monitoring via SNMP, thereby aggregating the sum status only from the remaining SNMP table entries. This is a very useful feature in case there are "known" errors within a multiplex which the operator does not want to be considered while building the aggregated status of a monitoring parameter.
This feature is supported across all monitoring layers and used wherever tables are useful, making monitoring very efficient even if there are "known" problems inside the multiplex.
The SNMP MIB further supports sending of SNMP TRAPs, which can individually be configured in any regard.
For each TRAP it can be configured, whether:
- a TRAP shall get sent with every state change of the particular monitoring parameter or only, if the state gets worse
- a TRAP shall get sent continuously as long as a warning or error condition of the particular monitoring parameter is set or whether the TRAP shall get sent only once when the state changes
- a TRAP shall get sent for error conditions only or for warning + error conditions of the particular monitoring parameter
- a TRAP shall contain further detailed state information or just the new state of the particular monitoring parameter
This flexibility and the versatile configuration possibilities make the SAM-MT 400 ideal for any monitoring purposes for DVB-T, DVB-H, DVB-S and DVB-S2.
