DMD50 Universal Satellite Modem
ROM Map 7 could also be used as the template for an Active Transmit (Drop) and/or Active
Receive (Insert) Map with a modulator and/or demodulator configured for 1024 Kbps operation.
This would be used with T1 or E1 frames where channels 1 through 16 are mapped into time slots
1 through 16 (in any order). Map slots 17 through 30 would be ignored.
ROM Map 7 could also be used as the template for an Active Transmit (Drop) and/or Active
Receive (Insert) Map with a modulator and/or demodulator configured for 1536 Kbps operation.
This would be used with T1 frames where channels 1 through 24 are mapped into time slots 1
through 24 (in any order). Map slots 25 through 30 would be ignored.
ROM Map 8 could also be used as the template for an Active Transmit (Drop) and/or Active
Receive (Insert) Map with a modulator and/or demodulator configured for 1920 Kbps operation.
However, this mapping would be relevant with E1 frames where time slot 16 is used for the
multiframe alignment signal and therefore channels 1 through 30 are mapped to time slots 1
through 16 and 17 through 31.
