Cisco Systems 3825 manual RAN-O Implementation Limitations and Restrictions

Chapter 1 Overview of the Cisco 3825 Mobile Wireless Edge Router

Limitations and Restrictions

Caution The Cisco 3825 router does not support OIR of network modules. Any attempt to perform OIR on a card in a powered up router might cause damage to the card.

Note The Cisco NM-2W network interface module only is only supported on the Cisco 3825 router on 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 Figure 1-5 on page 1-13).
