The customer have 4 ADSL line (for different purpose) subscribed, they plan to purchase Cisco 2821 ISR before ASA5510, the problem is I can't find seem to configure the router to accept 4 incoming line. In old 2620 time we can purchase NM-4E, but for ISR series I can only find HWIC-4ESW (that is 4-port single-wide 10/100Base-T Ethernet switch).
My question: Is HWIC-4ESW same as NM-4E that allow me to have 4 incoming and outgoing traffic? Or else what would be the solution.
Thanks.
