We currently have been quoting and supplying ESW 520 swithces for phone systems ass the SPA phones dont have GB uplink.
What is the differences other than price between these and SF an SG series?
Are ther SBCS phones with GB uplinks ?
Yes, the switching fabric and forwarding rate is higher on the newer switches. Check out the phone matrix I uploaded, I think you will be happy with that.
The main differences are as follows
SG = Gigabit 10/100/1000
SF = Fast Ethernet 10/100
200 Series = L2 switch
300 Series = L3 Switch
You can have an SG200 or SG300 switch. Same as SF200 or SF300.
