• Fax/modem/PBX voice gateway—Foreign exchange station (FXS) ports on the Cisco Catalyst 4500 AGM can
support up to 22 fax machines, speakerphones, modems, analog phones, and PBX lines tosupplement IP phones
at a campus or branch.
• Public Switched Telephone Network (PSTN) voice gateway—The Cisco Catalyst 4500 AGM incorporates a
96-channel DSP farm with up to 6 digital (T1, E1, Primary Rate Interface [PRI], Basic Rate Interface [BRI]) or
analogForeignexchangeoffice(FXO) interfaces with compression and echo cancellationservicesforconnectivity
to the PSTN or toll bypass with ISDN dial backup. Signaling support includes T1 channel-associated signaling
(CAS), BRI signaling, ISDN PRI, Q.SIG, and R2 signaling.
WAN Routing Features
• Cisco IOS Multiprotocol routing—The Cisco Catalyst 4500 AGM supports multiprotocol routing with support
for IP, IPv6, Internetwork Packet Exchange (IPX), AppleTalk and System Network Architecture (SNA)as well as
Web Cache Control Protocol version 2 (WCCPv2).
• WAN interfaces—Up to six WAN interfaces are supported per module, including T1, E1, PRI, BRI, and serial
ports.
• WAN security—Security optionsincludefirewall, intrusion detectionsystem (IDS), NetworkAddressTranslation
(NAT) and hardware-based IP security (IPsec) with 3DES data encryption for secure VPN or public Internet
connectivity.
• Quality of service (QoS)—Features such as the Resource Reservation Protocol (RSVP), Protocol Independent
Multicast (PIM), traffic shaping, custom and priority queuing, Low Latency Queuing (LLQ), and Weighted Fair
Queuing (WFQ) ensure a consistent QoS for data, voice, and video applications over the WAN.
Benefits for Campus and Branch Office Deployments
The Cisco Catalyst 4500 AGM may be deployed in a range of applications where WAN connectivity or integrated
IP telephony services are required. As an ideal solution for medium to large integrated branch offices, the AGM can
bedeployed with bothWANinterfacesand IP telephonyservices(including voice gateway telephonyservices)or only
with WAN connectivity and services. In the wiring closet, the AGM enables the deployment of IP telephony services
at the network edge boosting scalability and enhancing availability.
The benefits of deploying the Cisco Catalyst 4500 AGM include:
• Reduced network complexity—Deploying the AGM in the Cisco Catalyst 4500 Series provides a complete,
integrated branch office solution combining robust intelligent LAN switching with WAN routing, and
comprehensive IP telephony support. Consolidating the infrastructure for LAN switching, WAN routing, and
telephony improves deployment times and reduces network complexity and administration overheads, resulting
in enhanced productivity of the IT staff. Integrated voice gateway services enable VoIP toll bypass with
compression over the IP WAN to reduce WAN costs, offering an economicalalternative toPSTN telephony while
the modular interfaces shared with the Cisco 1700/2600/3700 routers reduces the cost of sparing and network
support. Centralized MGCP and H.323 call control with the Cisco CallManager and SRST reduce network
administration costs.
