Figure 1. Cisco ISR Naming
1. Prefix
2. Product Number
• "810" = Machine-to-machine gateways (that is, for ATMs)
• "850" = Older Cisco 800 Series ISRs, replaced by Cisco 860 Series ISRs
• "860" = Current entry-level Cisco 800 Series ISRs; single WAN interface
• "870" = Older Cisco 800 Series ISRs, replaced by Cisco 880 Series ISRs
• "880" = Current midrange Cisco 800 Series ISRs; WAN + Wireless WAN backup (Cisco 880G ISR)
• "890" = Current high-end Cisco 800 Series ISRs; 2 * WAN (Active/Active or Active/Standby)
• "8x1" = RJ-45 Ethernet WAN interface
• "8x6" = DSL-over-ISDN WAN interface (very-high-bit-rate DSL/asymmetric DSL2 [VDSL/ADSL2] + Annex B)
• "8x7" = Basic telephone service WAN interface (VDSL/ADSL2 + Annex A), which allows splitter
• "8x8" = Basic telephone service WAN interface (G.SHDSL), which does not allow splitter
• "8x9" = Wireless WAN interface
• "86xVAE" = 1 * Ethernet and one identified by the third number (6 or 7):
both are physically present, but just one can be active at a time
• "891" = 1 * Gigabit Ethernet, 1 * Fast Ethernet, and one v.92
• "892" = 1 * Gigabit Ethernet, 1 * Fast Ethernet, and one ISDN (not ISDN DSL)
3. Product Capabilities
• "K9" = Security router
• "SEC-K9" = Security router with Advanced IP Services
• "W-A" = Router with 802.11n Wireless FCC compliance
• "W-E" = Router with 802.11n Wireless ETSI compliance
• "W-N" = Router with 802.11n Wireless Hong Kong, India, and Australia compliance
• "W-P" = Router with 802.11n Wireless Japan compliance
• "WD-A" = Router with dual and concurrent 2.4 GHz and 5 GHz frequencies with FCC compliance
• "WD-E" = Router with dual and concurrent 2.4 GHz and 5 GHz frequencies with ETSI compliance
• "WD-N" = Router with dual and concurrent 2.4 GHz and 5 GHz frequencies with Hong Kong, India, and Australia compliance
• "GN" = 802.11g and 802.11n capable
Note: The nomenclature "GN" was inserted at the beginning of Wireless n, therefore newer products do not have it but are still 802.11n capable.
• "G" = Router with 3G (older; carrier type was selected at ordering)
• "G-S" = Router with 3G for Sprint networks
• "G-V" = Router with 3G for Verizon networks
• "G-A" = Router with 3G for North America Global System for Mobile Communications (GSM) networks
• "G-U" = Router with 3G for universal 3.5G High-Speed Packet Access (HSPA) networks
• "G-B" = Router with 3G for BSNL networks
• "G+7"= Router with 3.7G HSPA+ Release 7 universal networks
• "G+7-A" = Router with 3.7G HSPA+ Release 7 AT&T networks
• "4G-V" = Router with 4G for Verizon networks
• "4G-A" = Router with 4G for North America Global System for Mobile Communications (GSM) networks
• "4G-G" = Router with 4G for universal networks (except Canada, Japan, Australia)
• "HG" = Hardened router if the G has "H" prepended
• "V" = Router with VDSL+
• "A" = Router with ADSL+
• "M" = Router with Annex M support
• "CUBE"= Router with integrated Cisco Unified Border Element (Cisco UBE) license

• "E" = Router with Ethernet in the First Mile (EFM) support (Exception: VAE; see under "Other")
• "EA" = Router with EFM and ATM support
• "VAE" = Router with multiple WAN interfaces (VDSL+, ADSL+, and Ethernet)
• "F" = Router with Small Form-Factor Pluggable (SFP) and RJ-45 combination port (on just the first Cisco 890 platforms; newer Cisco 890 platforms have it as well, without the "F" in the name)
• "FSP" = Router with "F" (as above) plus higher performance, positioned for Service Providers
