ATSC, ATSC MH SNMP Monitoring Probe - 19" rack mountable device

SAM-MT 450 is an SNMP enabled ATSC and ATSC M/H monitoring probe, which covers SNMP based monitoring of all important parameters on all technical layers. It covers:

RF layer
MPEG2 layer
M/H layer
IP/UDP/RTP/SDP layer
FLUTE layer
ESG layer
Audio/Video layer
Application layer (EPG, Closed Captioning)
Conditional Access layer

This rack mountable 19" device (1 RU) is suited for monitoring ATSC and ATSC M/H 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 ATSC / ATSC M/H multiplexes and all ATSC / ATSC M/H programs therein can be monitored continuously and simultaneously on all technical layers of the broadcast in real-time.

for more detailed information to the monitoring features and capabilities

SAM-MT 450 is the most comprehensive SNMP based monitoring probe available for ATSC and ATSC M/H. It provides outstanding monitoring features on all technical layers and monitors in-depth down to sub-feature-level.
It monitors all legacy ATSC and all MDTV programs simultaneously! No need to have separate monitoring solutions for legacy ATSC and for MDTV, SAM-MT 450 handles everything!

Key Attributes:

supports detailed ATSC and ATSC M/H 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 450 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 450 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 450 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 accross all monitoring layers and used whereever 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 possibilites make the SAM-MT 450 ideal for any monitoring purposes for ATSC and ATSC M/H.
