Quality of service (QoS)—supports committed access rate (CAR), policy routing, weighted fair queuing (WFQ), generic traffic shaping (GTS), Resource Reservation Protocol (RSVP)

For more information about the Cisco 1750 modular access router, refer to the Voice-over-IP Quick Start Guide.

Cisco 2600 Series Routers

Cisco 2600 modular multiservice routers offer versatility, integration, and power to branch offices. With over 50 network modules and interfaces, the modular architecture of the Cisco 2600 series easily allows interfaces to be upgraded to accommodate network expansion.

Key Benefits

The Cisco 2600 series enables businesses to extend a cost-effective, seamless network infrastructure to the branch office with the following benefits:

Investment protection—Because the 2600 series supports field-upgradable modular components, customers can easily change network interfaces without upgrading the entire branch office network solution.

Lower cost of ownership—By integrating the functions of channel service unit/data service units (CSU/DSUs), ISDN Network Termination (NT1) devices, firewalls, modems, compression or encryption devices, and other equipment found in branch office wiring closets in a single, compact unit, the Cisco 2600 series provides a space-saving solution that can be managed remotely, using network management applications such as CiscoWorks.

Multiservice voice/data integration—The Cisco 2600 series enables network managers to reduce long-distance interoffice calling costs and enables next-generation applications such as integrated messaging and web-based call centers. Using voice/fax modules, the Cisco 2600 series may be deployed in both Voice over IP (VoIP) and Voice over Frame Relay (VoFR) networks. When used with a packet voice trunk module, a single Cisco 2600 series router can support simultaneous processing of 60 voice calls, as well as routing and other services.

Enterprise/Provider class solution—Meets the requirements of multiservice enterprises and their managed service CPE providers with high-reliability features, multiple WAN connections, and the ability to migrate from data- only, to time-division multiplexing (TDM) voice and data, to packetized voice and data infrastructure.

For more information about Cisco 2600 series routers, refer to the Cisco 2600 Series Hardware Installation Guide.

Cisco Voice Gateway 200

The Cisco Voice Gateway 200 (VG200) enables you to connect Cisco IP telephony solution products such as Cisco IP phones to the Public Switched Telephone Network (PSTN) or to a private branch exchange (PBX). Analog telephones or fax machines can also be connected.

The Cisco VG200 chassis can hold a network module (NM) that provides processing and digital signal processor (DSP) resources, and voice interface cards (VICs), which provide the physical voice interfaces. A typical configuration includes an NM-2V network module and two VICs. These VICs can be any combination of Foreign Exchange Station (FXS), Foreign Exchange Office (FXO), ear and mouth (E&M), or Basic Rate Interface (BRI) (both user and network sides), for a total of four ports. Another common configuration of the Cisco VG200 is to use the digital T1/E1 Packet Voice Trunk Network Module that supports up to 60 voice channels (2-E1).

Features

The Cisco VG200 has the following key features:

Modular architecture—Enables interfaces to be upgraded to accommodate expansion or changes in technology as new services and applications are deployed.

Ease of administration—Can be managed, controlled, and administered using Cisco CallManager, but can also be accessed directly using the same command-line interface (CLI) as other Cisco IOS software-based products. When used with Cisco CallManager 3.0 or later as a call agent, the Cisco VG200 functions as a Media Gateway Control Protocol (MGCP) gateway.

Versatility—Provides a LAN interface to a fast10/100BASE-T Ethernet port, a console port for local access using a terminal, nonvolatile random-access memory (NVRAM) for storing configuration information, and dynamic random-access memory (DRAM) for main memory and shared memory. The Cisco VG200 supports MGCP on its FXS and FXO analog ports, while it supports H.323 on its T1 digital ports.

For more information about the Cisco VG200 gateway, refer to the
Hardware Configuration Guide for the Cisco VG200.

DT-24+ and DE-30+ Digital Gateway Modules

The DT-24+ and DE-30+ digital gateways are modules that are used with Cisco CallManager to connect Cisco IP phones to the Internet. The DT-24+ or DE-30+ module is installed in a 32-bit Personal Computer Interface (PCI) slot in a PC desktop or server chassis.

Digital gateways differ from analog gateway products in that they support digital ISDN features including Direct Inward Dialing (DID) and caller ID. These features allow outside callers to dial directly to a particular user without going through an attendant (operator). In addition, digital interfaces usually provide a more economical interface choice when the number of trunks exceeds six to eight channels.

When more than one digital gateway is needed, the additional gateway can be treated as a separate gateway or aggregated with the other gateways as a common pool of channels. Any number of digital gateways can be installed in a network, and the number installed in a PC is limited only by the number of available slots.

Digital gateways communicate with Cisco CallManager, which allows the implementation of supplementary services such as holding, transferring, and forwarding of outside calls. Also, with proxy signaling provided by the Cisco CallManager, the digital gateways are fully compatible with H.323 V.2.

DT-24+ Digital Gateways

DT-24+ digital gateways provide the interface to the PSTN or existing PBX systems through T1 ISDN Primary Rate Interface (PRI) interfaces. DT-24+ digital gateways support up to 23 simultaneous channels of VoIP packet to circuit-switched adaption, G.711 encoding (A-law or mu-law), dual tone multifrequency (DTMF) detection, generation, and signaling, and line echo cancellation. Twenty-three simultaneous channels of G.723.1 encoding/decoding are also supported.

DT-30+ Digital Gateways

DT-30+ digital gateways provide the interface to the PSTN or existing PBX systems through E1 ISDN PRI interfaces. DE-30+ digital gateways support up to 30 simultaneous channels of VoIP packet to circuit-switched adaption, G.711 encoding (A-law or mu-law), dual tone multifrequency (DTMF) detection, generation, and signaling, and line echo cancellation. Thirty simultaneous channels of G.723.1 encoding/decoding are also supported.

Features

DT-24+ and DT-30+ digital gateways include the following features:

A single PCI-based card (PCI bus for power only) with the following components on board:

Integrated DSPs

T1 (RJ-48C female) interface (DT-24+) or E1 (RJ-48C female) interface (DT-30+)

10BASE-T Ethernet network interface (RJ-45 female)

Control processor with communications software to connect to Cisco CallManager (required) over TCP/IP/Ethernet link

Remote boot procedure with DHCP (for IP address) and TFTP software download (downloadable and upgradable)

T1/E1 PRI ISDN Layer 3 protocols, including National ISDN-2 (NI-2), 5 Electronic Switching System (5ESS), 5ESS custom, DMS100, DMS250, and other protocol support

Both user-side and network-side ISDN signaling support to emulate terminal equipment and switching equipment, respectively

Supports Skinny Gateway protocol communications with Cisco CallManager to provide supplementary services (such as hold and transfer) under control of IP telephony clients
