C8151-CVAI-G2 Description
The C8151-CVAI-G2 is a Cisco 8100 Series Secure Router with an embedded ISDN-side DSL modem and 5G radio for small branches on DSL or passive optical lines. The router has one 1GE RJ-45/SFP combo, one RJ-11 DSL and one XGSPON/10G BASE-T WAN port, plus two Flex and six LAN ports, with 5.6 Gbps of forwarding and 1.5 Gbps of IPsec. The VDSL/ADSL modem covers ISDN lines (Annex B/J) only, and cellular comes from an embedded 5G Release 17 module with dual nano SIM slots rather than a pluggable one.

Product Performance
Key Features
The RJ-11 port terminates VDSL and ADSL over ISDN (Annex B/J). VDSL2 profiles run from 8a up to 35b, so the modem needs no separate DSL bridge.
A dedicated XGSPON/10G BASE-T port sits beside the RJ-11 DSL port and the 1GE RJ-45/SFP combo port, giving three different WAN interfaces on the chassis.
The 3GPP Release 17 module is built in, with dual nano SIM slots and 5G FR1 and LTE band coverage. It does not use a pluggable module bay.
Forwarding is 5.6 Gbps at 512 bytes and IPsec is 1.5 Gbps. SD-WAN measures 900 Mbps and Threat Protection 1 Gbps with its listed security features enabled.
The higher scale tier gives 500K IPv4 routes, 500K IPv6 routes, 4K VRFs and 10K ACEs for sites that keep traffic classes in separate routing tables.
Typical draw is 27W from a 66W external supply. The body measures 1.57 x 7.8 x 10.8 in at 5.1 lb, and device software starts at Cisco IOS XE 26.1.1.
Application Scenarios
A branch served by an ISDN-delivered DSL line uses the RJ-11 port as its primary path, and the embedded 5G module gives it a cellular path that does not depend on that line.
A site with an XGSPON service terminates it on the XGSPON/10G BASE-T WAN port and runs SD-WAN at up to 900 Mbps over that line.
A remote office uses one fanless chassis for WAN termination, routing and local connectivity, with six LAN ports and two Flex ports for printers, phones and desktops.

C8151-CVAI-G2 and C8151-CVAP-G2 differ only in the embedded DSL modem: C8151-CVAI-G2 supports VDSL/ADSL over ISDN (Annex B/J) and C8151-CVAP-G2 supports VDSL/ADSL over POTS (Annex A), so the line type at the site decides between them. Both carry the embedded 5G Release 17 radio with dual nano SIM slots, six LAN ports, 5.6 Gbps of forwarding, 500K routes and a Cisco IOS XE 26.1.1 floor. A site with Ethernet circuits only and no DSL line moves to C8151-G2, which replaces the DSL and XGSPON/10G BASE-T ports with a second 1GE combo WAN port and takes an optional pluggable LTE or 5G module, at 23W of typical draw against 27W and a 17.18.1 floor.
