CISCO 3600 FEATURES AND BENEFITS

The Cisco 3660, Cisco 3640, and Cisco 3620 routers support the following network applications and services:

• Analog and Digital voice service
  • The voice/fax network modules for the Cisco 2600 and 3600 series multiservice access routers enable packet voice technologies including VoIP and VoFR. Ciscos voice solutions provide the means for integrating both voice and data within a single network and allow users to take advantage of services, such as toll-bypass, without sacrificing voice quality. The digital T1/E1 Packet Voice Trunk Network Module provides a flexible and scalable T1/E1 voice solution and supports up to 60 voice channels in a single network module. The analog voice/fax network modules slide into Cisco 2600 and 3600 chassis slots and contain either one or two voice interface card (VIC) slots. The VICs currently available are two-port foreign exchange station (FXS), foreign exchange office (FXO), E&M 2-wire and 4-wire interfaces and a basic rate interface (BRI). The voice modules support all major industry codecs including G.711, G.723, G.726, G.728, G.729 and G.729a/b for customized solutions and to meet the need for high voice quality and bandwidth efficiency
• ATM networking services
  • Four new multiport T1/E1 ATM network modules with Inverse Multiplexing over ATM (IMA) and 3 ATM OC-3 network module are now available for the 3600 series multiservice access platforms. These new multiport ATM modules allow service provider and enterprise customers to cost-effectively increase bandwidth, extending multiservice capabilities to remote-branch-office locations through ATM. These network modules support a robust set ofATM features including UBR, VBR-rt, VBR-nrt, and ABR ATM class of services, ATM Forum User Network Interface (UNI) 3.0, UNI 3.1 and UNI 4.0 signaling, Permanent Virtual Circuits (PVCs) and Switched Virtual Circuits (SVCs), and ATM Adaption Layer 5 (AAL5) to name a few.
• Dial-up services
  • The Cisco 3600 is a midrange dial-up platform that fits between Ciscos AccessPath and AS5300 products at the high end and the Cisco 2500 series access servers at the low end. Mixed-mode and high density ISDN and asynchronous configurations offer substantial flexibility in dial-up applications. Integrated digital modems (with support for PRI, BRI, CT1 and R2) and new integrated analog modems further enhance the dial access flexibility and scalability of the Cisco 3600.
• ISDN PRI networks
  • The Cisco 3600 series offers high levels of cost effective ISDN PRI concentration. A Cisco 3640 configured with a Mixed Media LAN/ISDN PRI network module and three 2-port ISDN PRI network modules supports up to 186 (T1) or 240 (E1) B channels. This is a powerful and cost effective way to aggregate many branch offices and telecommuters onto one corporate network.
• ISDN BRI networks
  • For areas of the world where ISDN BRI services are more widely available or cost effective, the Cisco 3600 series supports many BRI interfaces. Configured with a LAN network module and three 8-port network modules, a Cisco 3640 connects up to 48 B channels. In this way, one system provides high-density BRI interface dial-up support and local LAN and WAN routing connectivity.
• Serial networks
  • With support for up to 48 synchronous serial interfaces on the Cisco 3600, the Cisco 3600 series and its RISC processor are the perfect complement to the Cisco 2600, 2500, 1700 and 1600 series. The Cisco 3600s higher performance and modular design are appropriate for locations needing support for multiple T1/E1 links or the ability to change configurations in the future.
• Mixed WAN services
  • Many corporate environments require support for a mixture of ISDN PRI, ISDN BRI, asynchronous serial, and synchronous serial connections. The Cisco 3600 series is ideal for this scenario. It allows migration between interfaces or simultaneous support of several technologies.
• Multiservice access solutions and applications
  • The three Cisco 3600 models allow new levels of connectivity and performance for branch offices with their scalable size, slot density, and cost. Combinations of network modules provide new opportunities for branch offices needing more than a fixed-configuration solution. The Cisco 3620, for example, provides multiple LAN access server support for asynchronous, ISDN, analog modem and digital modem environments, which complements the Cisco 2500 series access servers. Alternatively, a Cisco 3620 adds multiple LAN capabilities to branch bank environments needing to assimilate legacy serial devices, connecting them all to a high-speed Frame Relay network.
• LAN-to-LAN services
  • Consistent with its other capabilities, the Cisco 3600 series offers midrange LAN-to-LAN connectivity for branch offices needing a flexible modular platform. The Cisco 2500 series, with a multitude of fixed configurations, offers cost effective branch office solutions including integrated routers and hubs, single and dual LAN routers, and multiple serial routers.

NETWORK MODULE OPTIONS FOR THE CISCO 3600 SERIES

The Cisco 3660, Cisco 3640, and Cisco 3620 routers are 6, 4, and 2 slot multiservice access routers, respectively, whose LAN and WAN connections are configured by means of interchangeable network modules and WAN interface cards. The Cisco 3660 also incorporates 1 or optionally 2 integrated 10/100 (Ethernet/Fast Ethernet) ports. The following network modules are available for the Cisco 3660, Cisco 3640, and Cisco 3620 routers:

• Analog and Digital (T1) Voice Network Modules
• Single-Port High-Speed Serial Interface (HSSI)
• ATM 25 Mbps Network Module
• ATM OC3 155 Mbps Network Module
• 6, 12, 18, 24, and 30 digital modem network modules
• LAN with modular WAN
• 8 and 16 analog modem network modules
• Channelized T1, ISDN PRI and E1 ISDN PRI network modules
• Combined FastEthernet and PRI network modules
• 4 and 8 port ISDN BRI network modules
• 16 and 32 port asynchronous network modules
• 4 and 8 port synchronous/asynchronous network modules
• 1 and 4 port Ethernet network modules
• 1 port Fast Ethernet (10/100) network modules (100BaseT "TX" and Fiber "FX")
• 8 and 16 port analog modem modules
• 4 port serial network module
• Compression network module

In addition the Cisco 3660 supports 2 internal AIM slots. The Data Compression Advanced Integration Module (AIM) for the Cisco 3660 Series delivers a cost-effective option for reducing recurring wide-area network (WAN) costs and maximizing the benefit of the advanced bandwidth management features of Cisco IOS (R). The Data Compression AIM takes advantage of either of the two available Cisco 3660 internal AIM slots, ensuring that external slots remain available for components such as integrated analog voice/fax, digital voice/fax, ATM, channel service unit/digital service units (CSU/DSUs), analog and digital modems.
