1841 Modules.
Posted by qualityofservice on May 6, 2009
I’m putting this here for my own reference. I forget this all the time. Stemmed from an argument with another admin who insisted that his Cisco SE told him that an 1841 supported FXS/FXO and E&M modules.
FAQ: http://www.cisco.com/en/US/prod/collateral/routers/ps5853/prod_qas0900aecd80181208.html
Module support: http://www.cisco.com/en/US/prod/collateral/routers/ps5853/product_data_sheet0900aecd8016a59b.html (bottom of page)
Long story short: supports wireless and every WAN under the sun (DSL/Cable/T1/E1/ISDN/Serial); no support for voice cards.
Voice can transit it like any other data packet, but the router itself cannot terminate voice circuits.
If the above is untrue, then Cisco’s documentation is woefully out of date.
