Used Cisco 2800 Series Routers
There are four models in the Cisco 2800 Series of Routers. The Cisco 2801, 2811, 2821, and 2851 make up the four options a customer can choose from. The CISCO2801 has (2) DSP Slots for PVDM2 Modules, 2 Fast Ethernet Ports, and four slots for HWIC, VWIC, WIC, and VIC Cards. Check the matrix for configurations available. If you're getting a T1 line, the you'll need the second generation T1 WIC Card p/n WIC-1DSU-T1-V2 for any of the Cisco 2800 series routers.
The CISCO2811 also has (2) DSP Slots for Voice PVDM Modules and 2 Fast Ethernet Ports, though it has 4 Cisco HWIC Module Slots and 1 NME Slot. If you're getting a channelized Voice T1 line, then you'll want a VWIC-1MFT-T1 for single line or a VWIC-2MFT-T1 for dual channelized voice T1's.
The CISCO2821 and CISCO2851 both have (3) DSP Slots for Cisco PVDM2 Modules, 2 10/100/1000 GIG Ethernet Ports, 4 HWIC Modules Slots, and 1 NME Slot (the 2851 can accept NME-X or NME-XD).
We often see customers package these 2800 series routers with voice network modules including the NM-HD-2V and Voice Interface Cards like the VIC2-4FXO for Voice Over IP (VOIP) Solutions. Another popular add-on is the NM-16ESW, which adds (16) 10/100 Fast Ethernet Ports and the NM-16ESW-PWR which has Power Over Ethernet (POE) for the 16 Ports. If you need the router to have two additional WIC slots for expansion, then you'll need the NM-2W. If you're getting a T3 line for 45 Mbps of throughput, you'll be looking at the NM-1T/E3. You'll find many of the available Cisco Network Modules here at our store as well. If you can't find it in our store, just give us a call.
