Harley ProSwitch IP/ASI Redundant Switching Switch

For scenarios that require fast, intensive, and reliable TS stream switch redundancy, Harmonic's ProSwitch is the best solution, ensuring 24/7 availability of digital television signals.

If your business cannot afford downtime, you can rely on ProSwitch. This compact standalone system continuously monitors MPEG-2 TS and seamlessly switches to a backup when it detects a failure in the primary stream.

Flow. Whether used for device redundancy or network link redundancy, ProSwitch demonstrates its high performance, flexibility, and delay compensation features, maximizing the robustness of broadcast and transmission links.

Robustness and Maximum Normal Operating Time — Ensuring the Safety of Broadcasting and Transmission

ProSwitch offers up to 16 groups of IP switch-over or 4 groups of ASI switch-over in a 1 RU unit. The high-density ProSwitch saves costs, power, and space, helping operators reduce deployment expenses.

and operating costs.

Reliability and Flexibility

ProSwitch can utilize Gigabit Ethernet or ASI interfaces, making it suitable for any type of architecture: from widely deployed ASI interfaces to new IP-centric networks. The switch is equipped with dual power supplies, ensuring reliability.

The security of program transmission is maximized, with Gigabit Ethernet and ASI interfaces featuring an intelligent configurable bypass mechanism that allows program transmission to continue even in the event of a power failure.

Richly configurable testing conditions

ProSwitch measures the operational status of input streams through various configurable test conditions. It supports the TR 101 290 standard (three priority levels) and provides complete operation for digital DVB networks.

Condition Check. This device also supports the same level of testing conditions and monitoring modes in the ATSC environment. To enhance switching capability, ProSwitch offers template checks for expected PIDs and rate.

the status check for scrambling of restrictions and/or various key program segments can be configured in ProSwitch for each test condition, along with its critical alarm levels to trigger switching or log alarms. In addition,

ProSwitch allows you to set the detection alarm trigger time to avoid unnecessary switching during transient events (time duration mechanism).

Delay compensation feature

ProSwitch simultaneously analyzes input streams with delays (ranging from milliseconds to seconds) and provides delay compensation functionality. If a fault is detected in one input, the device will compensate for the time difference, ensuring no disruption.

Switching the sewing to another normal transmission stream does not affect the end user at all. Typical applications include link distribution redundancy switching.

Designed for Ground Transmission

By preserving the SFN structure of the input transmission flow, ProSwitch enables seamless switching in DVB-T/T2 terrestrial transmission networks. For DVB-T, ProSwitch can rearrange the upstream.

The jumbo frame structure generated by the SFN adapter. For DVB-T2, this device can still rearrange the data from the upstream DVB-T2 gateway (such as Harmonic's ProStream™ X multiplexer).
