4 Updates to Cisco AS5300 Universal Access Server Module Installation and Software Configuration Guides
Safety Recommendations
VoIP Card
The VoIP card resides in one of the slots in the Cisco AS5300 universal access server. Up to five DSP
modules can be installed onto the voice card to perform voice processing for up to 30 B channels for
single-density DSPs and 60 B channels for double-density DSPs.
• CPU: MIPS 4700 100 MHz
• Support chipset: GT-64010 system controller
• DRAM: Standard 72 pin SIMM (4, 8, 16 MB)
• Flash memory: Cisco proprietary Flash 80 pin SIMM
• Five DSP module sockets
DSP Modules
The DSP module provides voice compression and packetization services to the voice card so that
you can both configure and expand it.
• Six DSPs per DSP module, use four DSP modules for T1 applications and five DSP modules for
E1 applications
• Uses TI TMS320C542 50 MHz or TI TMS320C549 100 MHz
• DSP SRAM: 128 Kwords (16 bit)
