Does cisco 1841 support WAN??

[Jaderson Pessoa · Accepted solution]

Yes, support.

The modular architecture on the Cisco 1841 router supports HWIC slots. The newly designed high-speed WAN interface slots significantly increase the data-throughput capability (up to 800-Mbps aggregate). Table 6 lists the High Speed WAN Interface cards supported on the Cisco 1841.
• Both slots on the Cisco 1841 router are HWIC slots and provide compatibility with WICs and multiflex trunk (VWICs) interface cards
(for data only).

Hi there,

Yes, the 1841 is an ISR G1 router. Slow by todays standards but definitely a WAN router. Take a look at the array of WIC cards it supports:
