Release Notes for Cisco ASR 901 nV Series Aggregation Services Router for Cisco IOS Release 15.4(4)S
This release notes is for the Cisco ASR 901 nV Series Aggregation Services Router for Cisco IOS Release 15.4(4)S and contains the following sections:
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 Network Virtualization (nV) feature uses the Cisco ASR 901 Series Aggregation Services Router as a satellite to the Cisco ASR 9000 Series Aggregation Services Router. The nV mode of operation is separate from the standard mode of operation of the Cisco ASR 901 router. The features available in the standalone mode are not supported on the nV mode and the features available on the nV mode are not supported on the standalone mode.
Note For steps to convert a Standard Cisco ASR 901 Router to Satellite (nV) router, see the Network Virtualization Using Cisco ASR 901 Series Aggregation Services Router as a Satellite guide at: http://www.cisco.com/c/en/us/td/docs/wireless/asr_901/Reference/guide/nv.html
Table 1 lists the Cisco ASR 901 router model versions that are supported as satellites.
Note TDM ports are disabled on the FT version of the Cisco ASR 901 router.
