Major Applications

Cell-Site Backhaul for Mobile Applications

Deployed as cell-site routers for mobile backhaul, the Cisco ASR 901 routers can aggregate multiple base stations

through multiple TDM, Ethernet, and IP interfaces, and can use Multiprotocol Label Switching (MPLS), Resilient

Ethernet Protocol (REP), Multilink Point-to-Point Protocol (MLPPP), Layer 2 VPN (L2VPN), Layer 3 VPN (L3VPN),

and other common transport protocols for RAN backhaul. Essentially, the routers prioritize, differentiate, and

segment any combination of 2G, 3G, or 4G traffic for backhaul over any combination of IP/Ethernet and TDM

(E1/T1) infrastructures (copper, microwave, or optical).

Enterprise Small Cell Backhaul

Mobile traffic will now traverse from enterprise networks across public networks, so it is essential to protect the

integrity of both enterprise and carrier data. To provide secure transport across any enterprise network, a high-

performance IPSec acceleration engine is required. At the same time, it is important to be able to manage both

public and private networks through support for NAPT. The Cisco ASR 901 provides secure mobile transport to

satisfy the evolving backhaul requirements of deploying enterprise small cells.
