ProSwitch
IP & ASI REDUNDANCY SWITCH
ProSwitch特色:
Reliable & Flexible
Available with Gigabit Ethernet or ASI interfaces, the ProSwitch is suitable for any type of architecture:
from widely deployed ASI-based headends to new IP-centric networks. The switch is equipped with dual power
supplies/plugs to maximize service availability, and maintains service delivery via a smart and configurable bypass
mechanism on the GbE and ASI interfaces — even in case of power failure.
Highly Configurable Testing
The ProSwitch measures the health of incoming streams via a wide range of configurable tests. It supports
TR 101 290 tests (Priority 1/2/3) to provide a complete health-status check of your digital DVB network. The
unit also supports testing and monitoring models that provide the same level of comprehensive information for
ATSC environments. To improve redundancy, template checking of expected PIDs, rate limits and/or scrambling status
of various critical program components are available. Each test can be configured and associated to a critical alarm level that
either engages switching or logs the alarm. In addition, tests can be set to avoid unwanted switching in the case of transitory events (time persistence mechanism).
Delay Compensation Capability
The ProSwitch offers delay-compensation capability by simultaneously analyzing delayed input streams (from several milliseconds to several seconds).
If one input is detected as being corrupted, the unit compensates for the time difference and switches seamlessly to the other uncorrupted stream without
any disturbance to end users. The typical application is network distribution redundancy.
Designed For Terrestrial Networks
ProSwitch can perform seamless switching for DVB-T/T2 terrestrial networks, by preserving the SFN structure of the incoming
transport streams. In DVB-T, ProSwitch can realign the megaframe structures, generated by the upstream SFN adapters. In a DVB-T2
environment, it also realigns the T2-MI streams generated by the upstream DVB-T2 gateways (such as the Harmonic ProStreamTM X processor).
In case of switching, the ProSwitch preserves the structure and timestamp on its output, avoiding service outage on DVB-T/T2 modulators caused by resynchronization.
Configuration & Supervision
The ProSwitch is equipped with a 100/1000Base-T port for control and supervision. The unit can be supervised and
configured remotely through any standard web browser, and provides a complete display of switching configurations,
along with easy-to-read input/output status information, error-log data and bitrate graphics. The ProSwitch embeds an SNMP agent for centralized management applications.
