Cisco Serial Speed

[AJ1982]

Dear All,

Our test lab has a selection of routers which provide the new style cisco serial to the old style cisco serial as the backbone.

Could someone let me know the max possible bandwidth and data rates we can get out of these, I can only muster up a couple of k, I trust this is probably the case but if someone could confirm.

Would it be faster if we went new style to new style?

Cheers

AJ

FatmanSuperstar,
Serial interfaces have a max speed of 2.048Mbps per port. It does not matter if you have the newer smart serial interface or the older DB60 interface. Both will operate at the same specs. I believe the smart serial interface was introduced so Cisco could incorporate more than one serial port into a standard WIC card.

To support serial speeds > 2Mpbs on an interface, you will need a HSSI (High Speed Serial Interface) module.
