Extended interface card installation

Now, we supplies only one extended interface card:8-port async card (EIC-8ASY).The width of  the product bus is 16~32bit and the number of  and the rate of the port supported are improved comparing to the common serial interface card.

The introduction to the serial interface refers to “Serial Interface Card Installation”.

 

8-port Async Card

8-port async card can be used in any slots of 1750/2620/2621 routers, in slot1/slot3 of 2630router, in slot1/slot4 of 2650 router.
