Cisco AS5800 Voice-over-IP Card

The Cisco AS5800 Voice-over-IP (VoIP) card is a multi-DSP (digital signal processor) coprocessing board and software package that adds VoIP capabilities to the Cisco AS5800 platform. The Cisco AS5800 VoIP card, when used with other cards such as LAN/WAN and modem cards, provides a gateway for up to 192 packetized voice/fax calls and 360 data calls per card. A Cisco AS5800 can support up to 1,344 voice calls.

Note The Cisco AS5800 must be running in split dial shelf configuration with two 7206VXR router shelves for maximum performance. Refer to the Cisco AS5800 Universal Access Server Operation, Administration, Maintenance, and Provisioning Guide for split dial shelf configuration information.

The Cisco AS5800 VoIP card resides on the dial shelf of the Cisco AS5800 platform. The onboard DSPs provide the signal processing functionality to convert voice/fax information into digitized packets. The DSPs are mounted on 16 daughter cards or Digital Signal Processing Modules (DSPMs).

The dial shelf communicates with the voice applications on the router shelf using Nitro Interconnect Protocol (NIP), which provides both reliable and unreliable data transfer over the backplane interconnect Fast Ethernet. For detailed software configuration information, refer to Voice over IP for the Cisco AS5800, an online document available at the following URL:

The Cisco AS5800 VoIP card can be used in applications such as the following:

Toll bypass
Remote PBX presence over WANs
Unified voice/data trunking
POTS-Internet phone gateway.

The Cisco AS5800 VoIP card supports multiple voice codecs, fax protocols, and H.323 call signaling and gatekeeper. The Cisco AS5800 VoIP card supports the following signaling protocols:

T1 (PRI or RBS)
E1 (PRI)
