Cisco 2911 Slot Numbering
Related article: Silencing a Cisco 2951 router. I recently purchased a Cisco 2911 to replace my 1921 for use at home, as I needed an extra WIC slot. Now that they’ve been obsoleted by the ISR 4000 series, they’re starting to appear on eBay for relatively palatable sums. I have got VIC2-2FXO card in cisco router 2911. One ADSL card is for broadband( internet ) connection. Four Cisco IP Phones 7960 are connected to router with extension number 5000, 5001, 5002 and 5003. PSTN line have been assigned a phone number with area and country code. I am using only one FXO port to pots line by using rj-11 to rj-11 cable.
We still receive quite a few POs on the 2900 series of ISRs from Cisco and even more hits at our website from users looking for information.
We put this comparison matrix together to help with the latter.
This info is also available elsewhere, but we have summarized this chart to show what people usually ask us about.
