Q. Is there voice ISDN PRI support on the integrated onboard WIC slots using the VWICs?
A. Yes. The HWIC slots can be used for voice ISDN PRI. VWICs can be used in conjunction with digital voice PVDM2s to support up to four
T1s of high-complexity voice channels.
Q. What is required for the chassis to support digital voice via the onboard HWIC slots?
A. The Cisco 3800 Series allows digital voice support via the new onboard PVDMs using the multiflex VWIC in the onboard WIC/VIC/HWIC
slots or in the NM-2W, NM-1FE2W-V2, NM-2FE2W-V2, NM-1FE1R2W network modules.
Q. What is the new HWIC slot numbering scheme on the Cisco 3800 Series?
A. The Cisco 3800 Series adopts a new HWIC slot numbering scheme, which is common across the Cisco 1800 and 2800 series. This new
numbering scheme enables ports on the interface modules to be assigned a fixed number depending on the physical slot that the module is plugged
into. The reference number stays the same and the configuration remains intact when modules are plugged into or removed from other slots. All
interfaces or voice ports on a modular HWIC/VIC/VWIC/WIC that are plugged into either the built-in HWIC slots or into any network modules
are now referenced as follows:
• interface type NME-slot-number/HWIC-slot-number/port-number
• voice-port NME-slot-number/HWIC-slot-number/port-number
NM-slot-number equals “0” for HWIC slots built onto the chassis.
ADVANCED INTEGRATION MODULES (AIMS)
Q. How many AIMs does the Cisco 3800 Series support?
A. The Cisco 3800 Series has two built-in AIM slots on the motherboard. These slots allow CPU offload with hardware-accelerated VPN (3DES)
encryption, with up to 50 percent higher performance levels than provided by the onboard hardware encryption acceleration module. The slots also
allow hardware compression and ATM capability, leaving the network module slots available for additional capacity while freeing up CPU
resources.
Q. What restrictions are there when using the AIMs?
A. Two AIM-ATMs and AIM-COMPR4s can be configured on the same platforms, but two encryption AIMs cannot be implemented
concurrently.
ONBOARD GIGABIT ETHERNET PORTS
Q. How many Gigabit Ethernet ports are there on Cisco 3800 Series systems?
A. There are two Gigabit Ethernet ports on Cisco 3800 Series systems. Port 1 is a fixed 10/100/1000BASE-T RJ-45. Port 0 can choose between
10/100/1000BASE-T RJ-45 and an SFP module slot. SFP modules are optional.
Q. How can I choose between the RJ-45 and SFP module slot in Gigabit Ethernet Port 0?
A. A new command-line interface (CLI) allows you to choose between the two media types. The “SFP” option will only come up if there is a SFP
module plugged into the slot. RJ-45 is the default.
