2Overview
The Cisco 2800 series integrated services routers include the Cisco 2801, Cisco 2811, Cisco 2821, and Cisco 2851 routers.
These routers differ as follows:
•Cisco 2801 routers support 2 HWIC/WIC/VIC/VWIC slots capable of supporting double-wide HWICs, 1 WIC/VWIC/VIC
slot, 1 VWIC/VIC (voice only) slot, 2 advanced integration modules (AIM), 2 packet voice data modules (PVDMs), 2 Fast
Ethernet connections, and 16 ports of IP phone power output.
•Cisco 2811 routers support 1 single network module enhanced (NME), 4 single or 2 double high-speed WAN interface cards
(HWICs), 2 AIMs, 2 packet voice data modules (PVDMs), 2 Fast Ethernet connections, and 24 ports of IP phone power
output.
•In Cisco 2821 routers, the network module slot adds support for a single network module enhanced extended (NME-X),
and an additional slot supports an extension voice module (EVM); 3 PVDMs are supported; the LAN ports support 2
Gigabit Ethernet ports; and 36 ports of IP phone power output are available.
•In Cisco 2851 routers, the network module slot adds support for network module double-wide (NMDs) and network
module enhanced extended double-wide (NME-XDs), and the IP phone power output is increased to 48 ports.
Note A high density extension module (HDEM) operates in the EVM slot on the Cisco 2821 and Cisco 2851 routers.
The EVM slot supports additional voice services and density without consuming the network module slot on those
routers.
