The DSP module provides voice compression and packetization services to the VoIP card so that
you can configure and expand them.
• 6 DSPs per DSP module, use 4 DSP modules for T1 applications and 5 DSP modules for E1
applications
• Uses TI TMS320C542 50 MHz
• DSP SRAM: 128 Kwords (16 bit)
Power Supply
Either an AC or DC power supply is available. The power supply provides DC power to the
installed cards via connectors on the backplane.
The internal power supply is a four-output switching power supply with power factor correction
and regulated outputs.
