Ran-O Implementation Limitations And Restrictions; Umts Iub And Gsm Abis Implementation Limitations And Restrictions - Cisco 3825 Software Configuration Manual

Limitations and Restrictions
The Cisco 3825 router does not support OIR of network modules. Any attempt to perform OIR on a card
Caution
in a powered up router might cause damage to the card.
The Cisco NM-2W network interface module only is only supported on the Cisco 3825 router on
Note
shorthaul with or without Inverse Multiplexing over ATM (IMA). It is not supported on the Cisco 3825
router on shorthaul with GSM.

RAN-O Implementation Limitations and Restrictions

The following list of restrictions applies when implementing the Cisco 3825 router in a Radio Access
Network-Optimization (RAN-O) configuration.
Hardware not Supported on the Cisco 3825 Router
Use of additional voice/WAN interface card (VWIC) cards. The only supported VWIC is the Cisco
2-port T1/E1-RAN.

UMTS Iub and GSM Abis Implementation Limitations and Restrictions

The following list of restrictions applies when implementing the UMTS Iub or GSM Abis application in
a RAN-O configuration.
Hardware not Supported for UMTS Iub
The Cisco MWR 1941-DC router does not support UMTS Iub as it does not include the Advanced
Integration Module (AIM) slot connector on the motherboard. Only the Cisco MWR 1941-DC-A router
and Cisco 3825 router are supported for UMTS Iub.
Hardware not Supported for GSM Abis
The Network Interface Module (NM-2W) does not support GSM Abis as the HDLC Controller channel
does not interface with the NM-2W. GSM Abis is only supported through the Cisco 2-port T1/E1-RAN
card through the four voice/WAN interface card (VWIC) ports on the Cisco 3825 router (see
on page
Cisco 3825 Mobile Wireless Edge Router Software Configuration Guide
