APPENDIX

Sample Configurations
The Cisco MWR 2941 supports a variety of topology designs based on various GSM configurations,
including the following common topologies:
A backhaul interface is used to transfer GSM traffic. The traditional backhaul interface is comprised
of one or more T1/E1 controllers logically combined to form a multilink connect (except HSDPA,
which uses the backhaul interface for T1/E1 line clocking).
A shorthaul interface is used to transfer GSM traffic from the BTS/Node-B to the Cisco MWR 2941
router and from the Cisco MWR 2941 router to the BSC/RNC. The traditional shorthaul connections
on the RAN devices are connected through the Cisco T1 or E1 interface card.
Topology naming conventions such as 3x2 and 4x3 are used to describe the type of deployment. The
first number signifies the number of GSM shorthaul interface connections and the second number
signifies the number of multilink backhaul interface connections.
