Cisco Systems ICS-7750 Manual De Usuario

Key features and benefits of the ASI81, MRP3-8FXS, ASI160, and MRP3-16FXS 
cards include the following:

High-density analog port support—Enables you to continue to support analog 
telephones as you migrate to IP Phones.

DSP support—Supports up to eight DSPs on the ASI160 and MRP3-16FXS, 
or ten DSPs on the ASI81 and MRP3-8FXS. Each DSP can handle multiple 
voice channels, depending on the codec complexity.

SNMP support—The ICS System Manager supports SNMP to operate with 
CiscoWorks2000 to provide central monitoring and troubleshooting of 
remote Cisco ICS 7750 systems.

Additional benefits of the ASI81 and MRP3-8FXS include the following:

Flexibility—The modular design encourages customization of the 
Cisco ICS 7750 to meet particular voice and data communication needs, 
easily adding capacity, Cisco IOS services, and redundancy as needs change.

Reliability—Proven Cisco IOS technology delivers reliable, end-to-end QoS 
over the PSTN and WAN among your branch offices, customers, and partners.

Investment protection—The architecture of the ASI81 and MRP3-8FXS 
incorporates VICs, WICs, and VWICs, a RAM memory expansion slot, and 
PVDM options. 

Internet and intranet access—Cisco IOS software provides features that make 
the ASI81 ideal for communications across both intranets and the Internet:

Multiprotocol routing (IP, IPX, and AppleTalk), IBM/SNA, and 
transparent bridging over ISDN, asynchronous serial, and synchronous 
serial such as leased lines, Frame Relay, SMDS, Switched 56, and X.25.

WAN optimization, including DDR, BOD, and OSPF-on-demand circuit, 
snapshot routing, compression, filtering, and spoofing to reduce WAN 
costs.

Network security features—ACLs, user authentication, authorization, and 
accounting (such as PAP/CHAP, TACACS+, and RADIUS), and data 
encryption.

Internal LAN security—Integrated Cisco IOS Firewall Feature Set using 
CBAC to protect internal LANs from attacks.
