The 901 is an environmentally hardened 1RU router with four 100/1000 RJ-45, four Gigabit Ethernet SFP, and four Gigabit Ethernet "combo" ports -- a mixture of RJ-45 and SFP. It also features 16 T-1/E-1 WAN connections.
The 901 is able to withstand temperatures as low as 40 degrees below zero Fahrenheit, and altitudes of 13,000 feet at temperatures of 104 degrees Fahrenheit. It supports Ethernet virtual connections for IEEE 802.1Q VLAN tagging, 802.1ad or "QinQ," Resilient Ethernet Protocol, 802.3ad Link Aggregation Bundles, Layer 2 Protocol Tunneling (L2PT), and Ethernet over MPLS (EoMPLS), among other features.
The 903 is a 3RU device with six interface module slots and two route/switch processors slots. Two RSPs are available for the router: one supports 2GB of memory and the other 4GB.
Interface modules include a one-port 10G Ethernet XFP card, eight-port 10/100/1000Mbps Ethernet and Gigabit Ethernet SFP, four-port OC-3/STM-1 or one-port OC-12/STM-4, and 16-port T-1/E-1. The router also supports three different Cisco IOS software licenses: The Metro Services license offers advanced QoS, Carrier Ethernet Layer 2 features, synchronous Ethernet and Ethernet OAM capability; the Metro IP Services license offers all capabilities of the Metro Services license with the addition of Bidirectional Forwarding Detection, Layer 3 routing protocols, multi-VPN routing and Layer 3 Multicast and Forwarding Customer Edge capabilities; and the Metro Aggregation Services license includes all of the above, plus MPLS and Circuit Emulation.
The 903 also include four additional optional licenses: two for enabling ATM and IEEE 1588-2008 Boundary Clock or Master Clock capabilities; and two to enable ports on the multirate OC-3 and OC-12 interface module.
The 9001 supports 120Gbps of throughput in a 2RU form factor. It has an integrated RSP and two modular bays that support 20-port Gigabit Ethernet, two- and four-port 10G Ethernet and future 40G Ethernet port adapters. The base chassis also has four integrated 10G Ethernet SFP+ ports.
The integrated RSP has 8GB of RAM and is capable of holding several million routes, Cisco says.
Cisco says the routers will help service providers address the growth in network-connected devices and traffic. Citing its own internal research, Cisco says there will be nearly 15 billion network connections, twice the world's population, by 2015.
Cisco says more than 500 service providers worldwide have deployed the ASR 9000.
Pricing and availability of the ASR 901, 903 and 9001 were not disclosed.
