New Features in Cisco IOS Release 12.4(16)MR
With Cisco IOS Release 12.4(16)MR, the Cisco 3825 router supports the following:

GSMmux—Global System for Mobile Communication (GSM) Abis Optimization
over IP
The Cisco GSM Abis Optimization and Iub Optimization solutions can optimize the excess capacity that
exists in the current RAN backhaul network. This eliminates the need to add new T1/E1 trunks to meet
growing demand and can even allow a number of existing trunks to be decommissioned.
The Cisco GSM Abis Optimization over IP technology improves T1/E1 bandwidth efficiency by 33% to
50%, corresponding to a GSM voice call capacity gain of 50-100% per T1/E1, depending on the nature
of the traffic on the interface.
UMTSmux—Universal Mobile Telecommunication System (UMTS) Iub
Optimization over IP
The Cisco Iub Optimization over IP technology for R4/R99 (ATM) UMTS RANs improves bandwidth
efficiency by as much as 15 to 40%, corresponding to a UMTS voice call capacity gain of 18 to 67%,
depending on the type of Iub header and ATM Adaptation Layer traffic sub-cell multiplexing
performance. For R5/R6 IP UMTS RANs, Cisco provides compression and low-overhead encryption.
