Blonder Tongue MUX-2A-QAM overview

  • 1Description

The MUX-2A-QAM 2 x ASI to QAM Multiplexer from Blonder Tongue will aggregate two ASI sources into one QAM output channel for delivery over a standard coaxial distribution network. It features a single QAM RF output in the 54 to 864 MHz range, and provides the capability to filter program streams and to assign major/minor or a single 4-digit channel number to each.

The MUX-2A-QAM also provides Emergency Alert System (EAS) program switching through a third ASI input and terminal block contacts. The EAS input source can be shared among multiple MUX-2A-QAM units by looping it from one to another unit without the need for external splitting and amplification.

Supports MPEG-2 transport stream tables: PAT, PMT, MGT, RRT, STT, and VCT
Re-maps duplicate PIDs, program numbers, and minor channel numbers
Allows sharing of the EAS input source among multiple units
User-defined major/minor or 4-digit CATV virtual channels
User-defined channel names
EAS input replaces up to 12 program streams
Supports PID filtering and PSIP re-assignment
Provides QAM 256 Output at 38.8 Mbps
Accepts ASI input as EAS input source
User-defined QAM Output Parameters
Maintains MPEG-2 mapping

    Blonder Tongue MUX-2A-QAM specs

    Connectors ASI: 2 x BNC female
    Emergency Alert System (EAS): 1 x BNC female
    Standard ASI: DVB-ASI; EN 50083-9 (MPTS / SPTS)
    Emergency Alert System (EAS): DVB-ASI; EN 50083-9 (SPTS)
    Transport Rate ASI: 270 Mbps
    Emergency Alert System (EAS): Single program at 3 Mbps (based upon 12 programs using 256 QAM output -- higher data rates can be used with a lower number of output programs as to not exceed the maximum allowable bit rate on the QAM output channel

    Note: The EAS program (when triggered) is multiplied by the number of output programs. A 3 Mbps EAS video file on 12 programs therefore equals 36 Mbps. This bit rate is acceptable when using 256 QAM that has a maximum of 38.8 Mbps.
    Level Range ASI: 720 to 950 mVpp (800 mVpp nominal)
    Emergency Alert System (EAS): 720 to 950 mVpp (800 mVpp nominal)
