Voice-over-IP (VoIP) Card

The VoIP card is a coprocessing card and software package that adds VoIP capabilities. The

VoIP capability enables a Cisco router to carry live voice traffic (for example, telephone calls

and faxes) over an IP network. The VoIP card is available as a spare or a factory-intalled card

within the chassis.

The VoIP card contains multiple digital signal processor (DSP) modules. It uses the

Cisco AS5300's Quad T1/E1 Public Switched Telephone Network (PSTN) interface and local-

area network (LAN) or wide-area network (WAN) routing capabilities to provide up to a 48/60

channel gateway for VoIP packetized voice traffic to/from T1/E1 time-division multiplexing

(TDM) traffic. Major applications of the VoIP cards include:

• Toll bypass

• Remote PBX presence over WANs

• Unified voice/data trunking

• POTS-Internet telephony gateways

You can install up to five DSP modules (DSPMs) onto the VoIP card to perform voice

processing for up to 30 B channels.

• CPU: MIPS 4700 100 MHz

• Support chipset: GT-64010 system controller

• DRAM: Standard 72 pin SIMM (4, 8, 16 MB)

• Flash: Cisco proprietary Flash 80 pin SIMM

• Five DSP module sockets
