Cisco NM-1A-OC3-POM, 73-9586-02 ATM OC3 module with single POM (SFP) slot
Cisco Systems® extends WAN connectivity by adding high-speed ATM access to remote branch offices with the Cisco® 3800 and 3900 ATM OC-3 Network Module.

A 155-Mbps ATM OC-3 network module is available on the Cisco 3825 and 3845 integrated services routers and on Cisco 3925 and 3945 Integrated Services Routers, starting with Cisco IOS ® Software Release 12.4(3) Mainline and 15.0(1)M respectively(Figure 1). The network module supports the ATM forum standard ATM Adaptation Layer 5 (AAL5) with the following ATM quality of service (QoS) traffic classes: unspecified bit rate (UBR), UBR+, real-time variable bit rate (VBR-rt), non-real-time VBR (VBR-nrt), available bit rate (ABR), and constant bit rate (CBR). Voice over IP (VoIP) and H.323 over ATM is supported over the WAN using the currently available onboard voice digital signal processors (DSPs), analog voice and fax network modules, and voice interface cards.
The network module has modular optics supporting the Cisco pluggable optical modules (POMs) and Cisco Small Form-Factor Pluggables (SFPs), simplifying the selection of network modules from six offerings to one. The SFPs support STM-1 framing standards over multimode, single-mode intermediate-reach, and single-mode long-reach fiber-optic interfaces. The module is a single-port module with LC-type connector. The single-mode SFPs combined with the ATM network module provide high-speed trunking for users with access to a fiber WAN, whereas multimode is ideal for connecting high-speed servers, switches, or hubs equipped with OC-3/STM-1 fiber connections.
Cisco IOS SP Services feature sets are required to support ATM. A maximum of one ATM OC-3 network module is recommended on the Cisco 3825 and Cisco 3925, and a maximum of two ATM OC-3 network modules are recommended on the Cisco 3845 and Cisco 3945

New Features
New features of the new network modules follow:
• RFC 1577 support for routing over ATM
• RFC 1483 support for multiple encapsulations over ATM
• ATM Forum User-Network Interface (UNI) 3.0, 3.1, and 4.0
• ATM permanent virtual circuits (PVCs) and switched virtual circuits (SVCs)
• LAN Emulation (LANE) 2.0
• Layer 2 per-VC queuing
• Up to 1024 simultaneous virtual circuits
• AAL5 ATM adaptation layer
• ATM service classes: UBR, UBR+, VBR-rt, VBR-nrt, ABR, and CBR (data only)
• Permanent virtual paths (PVPs)
• ATM bandwidth (resource) manager
• Multiprotocol over ATM (MPOA) client and server
• Multiprotocol Label Switching (MPLS)
• IETF Point-to-Point Protocol (PPP) over ATM
• Next Hop Resolution Protocol (NHRP)
• F4 and F5 operations and management (operation, administration, and maintenance [OAM]) cell support
• Interim Local Management Interface (ILMI)
System Requirements
• The new network module is supported on the Cisco 3825, Cisco 3845, Cisco 3925 and Cisco 3945
• SP Services feature sets of Cisco IOS Software Release 12.4(3) Mainline or above and 12.4(4)T or above are required.
• A maximum of one ATM OC-3 network module is supported on the Cisco 3825 and Cisco 3925 ; the maximum for the Cisco 3845 and Cisco 3945 is two.
• The system requires no additional flash or DRAM memory other than the Cisco IOS Software Release 12.4(3) Mainline and 12.4(4)T feature set specified minimum memory requirements.
• No slot dependent.
