Technical Specifications
ATM OC-3 Network Module System Requirements
• Only supported on the Cisco 3600 series routers at this
time
• Not supported on the Cisco 2600 series
• No slot placement restrictions on either platform
• Maximum recommended ona singleCisco 3640and Cisco
3620 is one
• Max two high-speed network modules in a Cisco 3640
(includes Fast Ethernet, ATM, HSSI)
• Requires Plus feature sets of Cisco IOS Release 12.0(3)T
or above
• Operates in conjunction with all currently available Cisco
3600 network modules and WAN interface cards (WICs)
Physical Characteristics
• One OC-3c/STM-1 SC typeconnector per network module
• Support SDH G.707 and G.708 specifications
• 4 LEDs including:
– Enabled—Network module is seated correctly and is
communicating to the bus
– RCLK—Carrier detect
– FERF—Far end Rx failure
– OOF—Out of frame error condition
– AIS—Alarm indication
• Maximumdistance supportof 2km for Multimode,15 km
for single-mode, Intermediate reach, and 45 km for
single-mode, long-reach versions.
ATM Standards Supported
• Multiprotocolencapsulation with supportfor LogicalLink
Control/Subnetwork Access Protocol (LLC/SNAP)
encapsulation and VC multiplexing (Internet Engineering
Task Force [IETF] RFC 1483)
• Classical IP and Address Resolution Protocol (ARP) over
ATM; client and ARP server (IETF RFC 1577; IETF RFC
1755; IETF RFC 1626)
• MPOA for IP, Novell IPX, DECnet, AppleTalk Phases 1
and 2, Connectionless Network Service (CLNS), Xerox
Network Systems (XNS), and Banyan VINES via IETF
RFC 1483
• ATMForumLANEmulation(LANE)including LEC, BUS,
LES, and LECS
• IETF PPP over ATM
• MPOA
• Tag Switching/MPLS (when approved)
ATM Services
• ATM Forum UNI 3.0, 3.1 and 4.0 signaling for
point-to-point and point-to-multipoint virtual circuits
• ATM Forum UNI 4.0 signaling for ABR SVCs
• ATM Forum ILMI for addressprefix acquisition and ATM
service address registration with UNI-compliant switches
throughout the ATM network
• ATM network service access point (NSAP) E.164 address
support
• F4 (virtual path) and F5 (virtual connection) OAM cell
segmentand end-to-end flows,remote deflectidentification
(RDI), and alarm indication signal (AIS)
Network Management
• The ATM OC-3 network modules will support the
following Management Information Buses (MIBs):
– MIB II
– Synchronous Optical Network (SONET) MIB
– ATM MIB
– ATM ILMI MIB
– LANE MIB
– RFC 406, 1595, 1695, and 2233
• CiscoWorks2000 and CiscoWorks network management
integration
• Enhanced setup configuration
• Text-based command-line interface (CLI)
Positioning
A maximum of one ATM OC-3 network module is
recommended on both the Cisco 3640 and 3620. The Cisco
3620 and 3640 will not support full 155-Mbps OC-3 line
rates. The actual maximum supported speed ranges between
20 and 80 Mbps, depending on packet size. Layer 2 traffic
shaping, bandwidth management, and improved ATM CoS
features including UBR, UBR+, VBR-rt, VBR-nrt, CBR, and
ABR of the OC-3 ATM network modules on the Cisco 3600
series make it an ideal choice for service providers who want
to provide differentiated, end-to-end solutions that combine
the performance and traffic management benefits of Layer 2
switching with the intelligence, scalability, and functionality
of Layer 3 routing. The Cisco 3600 series ATM OC-3
network modules should be considered in situations where a
multiservice platform with VoIP, hybrid dial access with
integrated modems, or integrated DSU/CSU functionality is
required.
