Introduction

The Cisco Catalyst 4500 Access Gateway Module (AGM) enables organizations to implement integrated IP Telephony and WAN services at campus and integrated branch office sites. The combination of the WAN and voice infrastructure into Cisco Catalyst 4500 Series switches gives organizations the ability to reduce network complexity, enhance employee productivity, and improve network deployment times through an integrated platform while preparing for data, voice, and video convergence across the enterprise.

The Cisco Catalyst 4000 AGM can be deployed in both Cisco Catalyst 4500 Series and Catalyst 4000 Series chassis which run either Catalyst OS (CatOS) or Cisco IOS® Software and is fully compatible with all Supervisor Engines. You can deploy multiple AGMs in the chassis to support higher density requirements or provide a higher level of availability and resiliency.

The Cisco Catalyst 4000 Access Gateway Module has three modes of functionality:

  • Voice network services

  • Voice gateway

  • IP routing

The Cisco Catalyst 4000 AGM is supported in the Catalyst 4500 and 4000 Series chassis with any Supervisor Engine that runs CatOS 5.5(1) or Cisco IOS Software Release 12.1(13)EW or later. The AGM itself runs a separate instance of Cisco IOS Software that must be release 12.1(5)YF or later to support CatOS Supervisor Engines or release 12.2(13)T or later to support Cisco IOS Supervisor Engines.

For more information, refer to Cisco Catalyst 4500 Series Access Gateway Module Data Sheet.

Features and Benefits

The primary features of the Cisco Catalyst 4000 AGM include Telephony and WAN routing.

Telephony Features

  • Survivable Remote Site Telephony (SRST)—The Cisco CallManager can be used for centralized control of the Cisco Catalyst 4000 AGM at campus and branch sites. The AGM supports both Media Gateway Control Protocol (MGCP) and H.323v2 interfaces to the Cisco CallManager. SRST enables a resilient IP Telephony service when connectivity to the Cisco CallManager is lost. The AGM provides SRST for up to 240 IP phones.

  • Audio-conferencing—The digital signal processor (DSP) farm on the Cisco Catalyst 4000 AGM can be used to support on-demand and dedicated reservationless audio-conference services for local and remote users. Audio transcoding between G.729 and G.711 enables efficient communications between callers who use different codecs (for example, campus phones that use G.711 and remote site phones that use G.729).

  • Fax/modem/PBX voice gateway—Foreign exchange station (FXS) ports on the Cisco Catalyst 4000 AGM can support up to 22 fax machines, speakerphones, modems, analog phones, and PBX lines to supplement IP phones at a campus or branch.

  • Public Switched Telephone Network (PSTN) voice gateway—The Cisco Catalyst 4000 AGM incorporates a 96-channel DSP farm with up to six digital (T1, E1, Primary Rate Interface [PRI], Basic Rate Interface [BRI]) or analog Foreign Exchange Office (FXO) interfaces with compression and echo cancellation services for connectivity 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 4000 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, which includes T1, E1, PRI, BRI, and serial ports.

  • WAN security—Security options include firewall, intrusion detection system (IDS), Network Address Translation (NAT) and hardware-based IP security (IPsec) with 3DES data encryption for secure VPN or public Internet connectivity. The Encryption Service Adapter (ESA) is a high-performance data encryption module that implements data encryption and authentication algorithms. For more detail about ESA, refer to Catalyst 4000 Service Encryption Adapter Installation and Configuration Note.

  • 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.

Voice Gateway Features

  • Cisco IOS IP routing, H.323v2, and MGCP VoIP gateway functions.

  • A DSP farm that supports up to 96 digital voice channels with G.711 or G.729a voice or analog voice, conferencing, and transcoding.

  • Fax relay, G.711 fax pass-through and modem pass-through services compatible with other Cisco IOS gateways.

  • Time-division multiplexing (TDM), that switches between analog and digital ports, enables faster connection speeds for modems and fax machines.

Advanced Voice Services

  • Conferencing—Each DSP bridges up to six participants in a single on-demand or dedicated, reservationless conference call.

  • Transcoding—Each DSP bridges up to two full-duplex channels from G.711 to G.729a.

  • Voice gateway—Each DSP supports up to four digital voice channels or analog ports, or two channels per DSP for Voice Interface Card (VIC) modules.
