DQMx (Digital QAM Multiplexer) accepts up to four inputs in ASI, 8VSB, and QAM formats, and delivers one output in
QAM format in the 54-864 MHz range. Two types of input modules are available (ASI and 8VSB/QAM), and any
combination of input modules is allowed - for example, DQMx can be equipped with 2 ASI and 2 8VSB/QAM input
modules.

Each ASI input module can process up to twelve channels, not to exceed 270 Mbps. Each 8VSB/QAM input module
can process up to twelve channels, not to exceed 19.4 Mbps for 8VSB or 38.8 Mbps for QAM 256. The QAM-modu­lated output can contain up to twelve channels, not to exceed 38.8 Mbps when operating in QAM 256 mode.
