In small business business or enterprises where we look to get a handy, feature and services rich router we look for Cisco ISR routers. This is due to the reason that these devices integrate alot into them and you do not need to buy separate hardware for separate services. For example small shopping outlets and where 8 to 10 people work doesn’t need to spend alot in the network infrastructure. If you suggest them to buy a router for routing and access point for wifi and then get the ISP connection then that may not be a very cost effective solution.Rather they will buy some devices which has all of this integrated into one box. And that is what Cisco ISR routers are , they are routers with access point , WLC(mobility express), Security, DSL, LTE , Switch module integrated into them.
In this blog we will discuss a little more about these devices.
These devices come in many flavors. Majorly Cisco has divided the platform on the basis of switching ports. Like you can have 4P model and 8P model where 4 and 8 switching ports are available.On top of that you have multi-connectivity option for WAN for example if you need DSL connection there there will a different model, if you need LTE then there will be a different module i.e. you do not need to unnecessary have a DSL port on your router if you don’t need it in future , you can choose the variant which is more suitable to your need.
For example see below table for WAN connectivity options :
ISR1111= Two GE WAN interfaces
ISR1112= One GE WAN Interface and One DSL Interface with G.FAST/VDSL2 35b/VDSL2 /ADSL2+ Annex B & J over ISDN
ISR1113= One GE WAN Interface and One DSL Interface with G.FAST/VDSL2 35b/VDSL2/ADSL2 + Annex A or M over POTS
ISR1116= One GE WAN Interface and One DSL Interface with VDSL/ ADSL2+ Annex B & J over ISDN
ISR1117= One GE WAN Interface and One DSL with VDSL/ADSL2 + Annex A or M over POTS
