Cisco Cisco IOS Software Release 12.2(15)MC1

With Cisco IOS Release 12.2(15)MC1a and later, the MWR 1941-DC router can be used to extend a 
mobile operator’s DCN to the cell site, providing the ability to remotely manage radio and cell site 
equipment remotely from the operations center.

A cell site DCN solution minimizes the need to dispatch technicians for every problem that might occur 
at the cell site by providing the ability to perform the following types of maintenance tasks remotely:

troubleshooting

diagnosis

repairs

control

upgrades

routine maintenance of the cell site devices

Additionally, the MWR 1941-DC router cell site DCN implementation provides IP connectivity to the 
cell site, enabling the use of IP-related applications that provide operation support (for example, web 
camera for site surveillance, IP telephone for voice connectivity, and LAN extension to the cell site to 
provide remote access to network applications, data, and access to the Internet and/or intranet). 

Cisco network modules and WAN interface cards used with the MWR 1941-DC router provide a variety 
of connectivity options at the cell site.

When being implemented in an Cell Site DCN solution, the Cisco MWR 1941-DC router requires the 
following system configuration:

Cisco IOS Release 12.2(15) MC1a or later software be installed.

Support of the NM-2FE2W-V2 requires Cisco IOS Release 12.2(15)MC1b or later.

Network Time Protocol (NTP) 

Network Time Protocol must be configured. The Cisco MWR 1941-DC router uses NTP to maintain 
a clocking source for the proper time stamping of system messages and log files.

Redundancy—Standalone Mode

The MWR 1941-DC router must be configured to operate in standalone mode. The standalone 
option must be configured from redundancy mode.
