I need to upgrade my 8540 to route between ATM and Ethernet.
Currently I am using a 7507 for all routing.
3 c8540-mrp-fcl Switch processor
1 c8540-mrp Route processor no Flash no clock
12 CES T1 Circuit Emulation T1s
1 622 SM ATM sm IR, (currently 30 PVCs)
1 155 MM 4 x OC3 (will be removed)
I will be upgrading the memory and flash on the C8540-mrp
I will be putting in a 2 port GigE card to connect to a 6509
Do I need a ARM-64K or ARM2 route processor as well, to route between Ethernet and ATM?
Will I need a Stratum 4 clock on the c8540-mrp?
Are there any other considerations I should be thinking about?
