Catalyst 2924M-XL switch, Catalyst
4003-DC switch, Cisco 3662-AC/DC-CO,
Cisco 3631-CO, and Cisco 2600 Series
modular access platforms, the Cisco 2600
Series supports central office (CO) serial,
X.25 and Internet protocol/open system
interconnection (IP/OSI) interfaces for
operationsmanagementinServiceProvider,
Inter-Exchange Carrier (IXC), and Post,
Telephone and Telegraph (PTT) networks.
The Cisco DCN solution supports
synchronous optical network/synchronous
digital hierarchy (SONET/SDH) network
element (NE) connectivity for alarm
monitoring and control, remote
provisioning, and software download.
Other operations systems network
applications include local number
portability and billing data collection. In
addition, competitive local exchange
carriers (CLECs) can use the Cisco 2600
2950G-24-DC switch,
in small point of presences (POPs) or
central office colocations for digital
subscriber line access multiplexers
(DSLAMs), voice switches, and
transmission operations networking.
New Models in Cisco 2600 DC
Family: 2600XM-DC and
2691-DC
The Cisco 2600XM-DC models provides
the same proven technology of the previous
Cisco 2600 Series platforms, including
®
Cisco IOS
support and the modularity of Network
Modules (NMs), WAN Interface Cards
(WICs) and Advanced Integration Modules
(AIMs). The Cisco 2691-DC-U model
provides the same module support as the
2600XM, increased performance (up to
70kbps), and even greater density and
scalability.
Themodular architecture of the Cisco 2600
Series allows interfaces to be upgraded to
accommodate network expansion or
changes in technology as new services and
applicationsare deployed.Service providers
can integrate the functions of multiple,
separatedevices into a single, compact unit,
thereby reducing the complexity of
managing DCN infrastructures. For
example, the Cisco 2600 Series supports
connectivity to legacy asynchronous and
X.25 devices as well as standards-based
IP devices, facilitating a graceful migration from legacy to next generation network elements. Driven by a powerful
RISC processor, the Cisco 2600 Series provides the extra power needed to support the advanced quality of service
(QoS), higher bandwidth and security features required forconnecting to today’s Network Operation Center (NOC)
systems.
The Cisco 2600 Series meets service provider’s critical physical requirements for equipment depth fitting right
alongside transmission equipment on standard 12 inch deep racks, and occupying only 1RU to 2RU in height.
Offeredin seven base configurationssupporting fixed single or duallocal-area network (LAN) ports,each Cisco 2600
also includes one network moduleslot, twowide-area network(WAN)interface cardslots andone ortwo advanced
integration module (AIM) slots. Rear access cabling allows easy connectivity; the modular design shares a large
number of modules with the Cisco 3600 and 3700 Series, permitting fast servicing of Field Replaceable Units (FRUs).
DC, AC and redundant AC power supply adapter modules are also field replaceable. Network Equipment Building
Standards (NEBS) Level 3/ETSI compliance is achieved when used with the Cisco 2600’s optional NEBs/ETSI kit.
Common Language Equipment Identification (CLEI) coding is provided for easy identification and tracking of
central-office equipment. Robust network management capability for the Cisco DCN solution is achieved by using
the CiscoWorks Management Software or the IE2100 appliance.

• PWR-2600-DC= Cisco 2600/2600XM DC power supply spare
• PWR-2691-DC-U= Spare Universal Power Supply 24 to 48 volts
Refer to Table 2, Cisco 2600 Series System Specifications for detailed product information
Note:
AC & RPS power supply versions are also available.
The WAN interface cards available for the Cisco 1700, 2600, 3600, 3700 platforms support a variety of serial,
Integrated Services Digital Network Basic Rate Interface (ISDN BRI), and integrated CSU/DSU options for primary
and backup WAN connectivity. Network modules available for the Cisco 2600 and 3700 Series support a broad
range of applications, including multiservice voice/data integration, analog and ISDN dial access, and serial device
concentration. The internal Data Compression AIM for the Cisco 2600 Series off-loads the task of performing
high-speed data compression from the Cisco 2600’s main CPU, allowing compressed data throughput of up to
8-Mbps while preserving external interface slots for other applications.

The alarm interface controller (AIC) is a network module that greatly expands the network monitoring and control
capabilities of the Cisco 2600 and 3700 Series routers. TheAIC functions as an integrated entity residing within the
Cisco 2600 platform to provide network alarm monitoring and proactive remote control of network elements. The
AIC reduces service-provider and enterprise operating expenses by facilitating an integrated solution to remote
networkmanagement. This eliminates theneed for a dedicatedexternal alarm-monitoring device. Greatly simplifying
network layout, monitoring, and control; resulting in lower operations, administration, maintenance, and
provisioning (OAM&P) costs. The AIC is supported in Cisco IOS 12.2(8)T and later. The AIC network module
supports 64 discrete alarm inputs, of which 8 of the last 64 alarm points are software-configurable to accept either
analog or discrete inputs. The AIC further supports 16 control relays to facilitate the proactive remote control of
network elements.

Alarm Interface Controller Network Module
The Alarm Interface Controller (AIC) is anetwork module that greatlyexpands the networkmonitoring and control
capabilities of the Cisco 2600 and 3600 Series routers. TheAIC functions as an integrated entity residing within the
Cisco 2600 Router toprovide networkalarm monitoring and remote control ofnetwork elements.The AIC reduces
service provider and enterprise operating expenses by facilitating a “singlebox” solution, doing away with the need
for a dedicated external alarm monitoring device. This greatly simplifies network layout, monitoring, and control
resulting in lower operations, administration, maintenance, and provisioning (OAM&P) costs. The AIC is supported
®
in Cisco IOS
12.2(8)T and beyond. The AIC network module supports 64 discrete alarm monitoring points, of
which 8 of the last 64 alarm points are software- configurable to accept either analog or discrete inputs. The AIC
further supports 16 control relays to facilitate the remote control of network elements.
The Cisco 2600 Series supportsall WAN Interface Cardsavailable forthe Cisco1600, 1700,3600, and3700 Series,
as well as two new dual-port serial WAN interface cards to maximize interface density and slot efficiency. The new
dual-serial port WANinterface cards featureCisco’s new,compact, high-density Smart Serial connector to support a
wide variety of electrical interfaces when used with the appropriate transition cable.

All Cisco 2600 Series are equipped with an internal slot to support one or two field-installable AIMs. AIMs use
function-specific hardware to off-load the main router CPU and accelerate processor- or resource-intensive services,
yieldingdramatically higher throughput and higherperformance than a software-only implementation. The AIM slot
has access to virtually all of the router’s resources, including the main system bus. The TDM bus and the serial
communications controllers make this a very flexible and powerful feature. Since the AIM is internally mounted,
external slots remain available for integration of other modular components such as CSU/DSUs, WAN interfaces,
or other devices such as modems, or packetized voice/fax processors.
The Data Compression AIM provides a cost-effective option for reducing recurring WAN costs and maximizes the
benefit of the advanced bandwidth management features of the Cisco IOS software. With compression ratios of up
to 4:1, the Data Compression AIM supports 8Mbps of compressed data throughput without imposing additional
traffic latency—enough to keep two T1 or E1 circuits full of compressed data in both directions simultaneously.
The Data Compression AIM supports industry standard LZS and Microsoft Point-to-Point Compression (MPPC)
algorithms and ensures compatibility with all Cisco products supporting hardware- or software-based compression.
For example, the Data Encryption AIM offloads encryption processing from the Cisco 2600 Series CPU, providing
10 times the performance over software-only encryption. The new AIM-VPN/BPII and AIM-VPN/EPII supports a
maximum number of 800 remote access tunnels when using the Cisco 2600 models. These modules offer hardware
accelerated DES/3DES and the new AES (Advanced Encryption standard) encryption at speeds up to 80-Mbps
performance (max based on 1400 byte packet size). In addition the AIM-VPN/BPII and AIM-VPN/EPII support
hardware-assisted layer-3compression serviceswhere bandwidthconservation maylower network connectioncosts.
The new AIM-ATM provides a high-performance hardware-based ATM access solution for one to four T1 or E1
connections supported by the T1 or E1 VWICs (for example, VWIC-IMFT-T1).This frees the network module slot
to support other functions. When used in combination with a high density voice network module (NM-HDV-xxx),
the ATM AIM supports ATM adaptation layer (AAL) 2 and AAL5 VoATM. In addition, the new ATM-VOICE-30
and ATM-ATM-VOICE-30 AIMs provides a cost effective solution for supporting voice services or digitalvoice over
ATM (AAL2 and AAL5) support, without the use of a network module.
