Can anyone tell me actual differences between the UC520 and UC560 with regards to memory and processor/performance. I have a customer who is running a UC520 with multiple services and high bandwidth internet. The only have 16 phones but they run the processor between 60 an 100% quite frequently. I'm trying to find some specs as to how the UC560 might improve performance and run at a lower CPU utilization. I've looked at the data sheets, but they are pretty vague with redards to the details. The 560 will support up to 104 phones, but it doesn't go into more detail than that.
I've never seen any performance data on the CPU and memory on paper. However, I can tell you that the UC560 has 3 Gigabit LAN interfaces, 1 Gigabit WAN interface, Has enough DSPs to support 2 T1s ( the UC520 can only support 22 channels on a single T1), and has enough horsepower to support 3 times the amount of phones.
What I can give you is the Show version data from a UC520 and a UC560:
Cisco UC560-T1E1-K9 (MPC8378) processor (revision 0x100) with 511180K/13108K bytes of memory. Processor board ID
MPC8378 CPU Rev: Part Number 0x80C4, Revision ID 0x21 22 User Licenses 4 Gigabit Ethernet interfaces 24 Serial interfaces 2 terminal lines 1 Channelized T1/PRI port 1 Virtual Private Network (VPN) Module 4 Voice FXO interfaces 4 Voice FXS interfaces 1 Voice MoH interface 1 cisco service engine(s) 256K bytes of non-volatile configuration memory. 254464K bytes of ATA CompactFlash (Read/Write)
Cisco UC520W-16U-4FXO-K9 (MPC8358) processor (revision 0x202) with 249856K/12288K bytes of memory. Processor board ID
MPC8358 CPU Rev: Part Number 0x804A, Revision ID 0x20 22 User Licenses 10 FastEthernet interfaces 2 terminal lines 1 Virtual Private Network (VPN) Module 4 Voice FXO interfaces 4 Voice FXS interfaces 1 Voice MoH interface 1 802.11 Radio 1 cisco service engine(s) 128K bytes of non-volatile configuration memory. 125440K bytes of ATA CompactFlash (Read/Write)
With this information, I can tell you that the UC560 has double the memory (512MB) and has a higher class CPU (MPC8378 CPU Rev: Part Number 0x80C4, Revision ID 0x21).
This is from boxes that are in my lab right now, so I can't guarantee the processor or anything will be the exact same as time progresses. Consider this a "snapshot in time" so to speak.
