Introduction

The Cisco ASR 901 Series Aggregation Services Router is a cell-site access platform specifically designed to aggregate and transport mixed-generation radio access network (RAN) traffic. The router is used at the cell site edge as a part of a 2G, 3G, or 4G RAN.

The Cisco ASR 901 router helps enable a variety of RAN solutions by extending IP connectivity to devices using Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Node Bs using High Speed Packet Access (HSPA) or Long Term Evolution (LTE), base transceiver stations (BTSs) using Enhanced Data Rates for GSM Evolution (EDGE), Code Division Multiple Access (CDMA), CDMA-2000, EVDO, or WiMAX, and other cell-site equipment.

It transparently and efficiently transports cell-site voice, data, and signaling traffic over IP using traditional T1 and E1 circuits, as well as alternative backhaul networks such as Carrier Ethernet and DSL, Ethernet in the First Mile (EFM), and WiMAX. It also supports standards-based Internet Engineering Task Force (IETF) Internet protocols over the RAN transport network, including those standardized at the Third-Generation Partnership Project (3GPP) for IP RAN transport. Custom designed for the cell site, the Cisco ASR 901 router features a small form factor, extended operating temperature, and cell-site DC input voltages.

Supported Hardware

Table 4 and Table 5 shows the SFP modules supported on the Cisco ASR 901 routers:

Important Notes

- 10G SFPs inserted into 1GE port provides 1GE speed.

- 10G SFPs inserted into 10GE port without a valid license provides only 1GE speed.

- 100M SFP works only with no negotiation auto command.

- If 1G SFP is used to connect a 10G port to a 1G port, you do not have to explicitly configure the no negotiation auto command to bring up the link.

- Effective with Cisco IOS Release 15.4(3)S, the auto-select feature is supported on 100M SFPs. However, this feature is not supported on combo ports.

- Remote Fault Indication feature is not applicable for 1G mode in 10GE ports. It applies only to 10G mode in 10GE ports.

- By default dual rate SFP works in 1G mode, to make it work in 100M mode, “no negotiation auto” should be configured.

- Dual rate SFP can be configured in 100M mode when inserted in 1G ports only.

- Dual rate SFP when inserted in 10G ports will work in 1G mode only.
