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.
