The following is a description of the router, its a 1941

Cisco IOS Software, C1900 Software (C1900-UNIVERSALK9-M), Version 15.1(4)M4,



Cisco CISCO1941/K9 (revision 1.0) with 487424K/36864K bytes of memory.
Processor board ID FCZ164960LU
1 DSL controller
1 Ethernet interface
2 Gigabit Ethernet interfaces
1 ATM interface
3 terminal lines
