C8130-VAI-G2 Description
The C8130-VAI-G2 terminates a DSL circuit whose local loop was built over ISDN. Cisco documents its embedded modem as VDSL/ADSL over ISDN, the Annex B/J family, and that single line is what distinguishes it from C8130-VAP-G2 in the ordering catalogue. Around the modem the router carries a 1GE RJ-45/SFP combo Ethernet WAN port and an XGSPON/10G BASE-T port, so one chassis can hold a copper broadband service today and a passive optical one later. Two Flex and two LAN ports serve the site, forwarding is 1.9 Gbps with 1.5 Gbps of IPsec, and the model is marked SD-WAN Capable No. The body is fanless at 3.5 lb on a 66W supply drawing 23W typical.

Product Performance
Key Features
The embedded modem is built for the Annex B/J family and the Annex A variant lives in a separate part number; nothing in software moves a unit between the two, which makes the ordering decision permanent at the moment the SKU is chosen.
The RJ-11 modem and the XGSPON/10G BASE-T port are both present on every unit, so a site does not choose between copper and fibre access at purchase and can be re-cabled when the provider changes the delivery.
ITU G.993.2 profiles 8a through 35b are all supported, so the same unit works on a long rural loop running 8a and on a short urban one running 35b without a different modem.
Beyond the three WAN media the chassis offers two Flex and two LAN gigabit ports, which is the practical device budget for the site since no expansion bay exists anywhere in the 8100 Series.
The routing-only models in this series sit on the lower table tier, so a broadband branch with a simple table fits comfortably while a segmented design with many VRFs does not.
The fanless 3.5 lb body draws 23W typical, which lets it sit in a shop, a surgery or a small office without adding audible noise or a cooling requirement.
Application Scenarios
Deployed where the incumbent copper plant was engineered around ISDN and the DSL service is delivered in the Annex B/J family.
Installed where a copper broadband service is in place and a passive optical circuit is expected, with both interfaces already on the chassis.
Placed in occupied commercial spaces where a silent, wall or desk mounted router terminates the site’s broadband line.

Cisco IOS XE 26.1.1 |
- The distance between C8130-VAI-G2 and C8130-VAP-G2 is one row of the data sheet. This unit’s modem is built for VDSL and ADSL over ISDN while the other is built for POTS delivery, and every remaining figure, from the XGS-PON port through the 280K route tier to the 26.1.1 software floor, is shared.
- Because nothing else differs, the risk in this pair is procurement rather than design. A specification written from throughput, port count or power draw will match both part numbers equally, and only the line technology recorded during the site survey resolves which one will train on the circuit.
- C8151-CVAI-G2 keeps the same ISDN-side modem and changes the rest: six LAN ports instead of two, an embedded 5G module with dual nano SIM slots, SD-WAN Capable Yes with 900 Mbps published, forwarding at 5.6 Gbps and the 500K route tier, in a 5.1 lb body at 27W.
- For deciding which SKU to order, take the line technology from the survey rather than from the specification, since that is the only thing separating this model from C8130-VAP-G2; then weigh cellular backup, fabric participation and LAN port count together, because those three arrive as a single step up to C8151-CVAI-G2.
Selection Guide
1. The Survey Result Outranks The Specification
Throughput, ports, power and dimensions are identical across the DSL pair, so a bill of materials built from those attributes cannot distinguish the two; the Annex family recorded at the site is the only input that selects correctly between C8130-VAI-G2 and C8130-VAP-G2.
2. No Software Path Between The Two Variants
Cisco publishes the DSL variant as a hardware property of each SKU rather than a configurable mode, so a unit delivered against the wrong survey has to be exchanged rather than reconfigured.
3. Installing Once Across A Copper-To-Fibre Transition
Both the RJ-11 modem and the XGSPON/10G BASE-T port ship on every unit, so a branch scheduled for a fibre cutover can be commissioned on copper now and moved to the optical service with a patch change instead of a second router.
4. Where Fabric Membership Changes The Part Number
This model is marked SD-WAN Capable No; a site that will be managed as an SD-WAN endpoint takes C8151-CVAI-G2, which carries the same ISDN-side modem alongside embedded 5G and the higher route tier, so fabric participation is bought as a chassis rather than added later.
5. Four Wired Positions Is The Working Limit
Two Flex and two LAN gigabit ports give four device positions and the series has no expansion bay; a site with more wired endpoints needs a local switch or the six-LAN-port C8151-CVAI-G2, and neither is addressed by the 1.9 Gbps forwarding figure.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
DSL Annex family from the site survey |
Confirm the recorded local loop is ISDN-delivered and matches Annex B/J. |
C8130-VAP-G2 carries the POTS variant and is otherwise identical, so this is the only attribute that separates the two orders. |
|
Provider profile support |
Confirm the provider profile falls within ITU G.993.2 8a through 35b. |
Cisco publishes that profile range for the embedded modem and a service outside it will not train. |
|
XGS-PON readiness |
Confirm whether the optical port will be used at commissioning or after a later cutover. |
The port ships on every unit, but an active PON service needs the provider handoff in place first. |
|
SD-WAN participation |
Confirm the site will not be managed as a Cisco Catalyst SD-WAN endpoint. |
Cisco marks this model SD-WAN Capable No; a fabric site needs C8151-CVAI-G2. |
|
Wired device count |
Confirm no more than four wired devices connect behind the WAN interfaces. |
Two Flex and two LAN ports are the full complement and the series has no expansion bay. |
|
Software image floor |
Confirm the image is Cisco IOS XE 26.1.1 or later. |
The DSL models sit on a different release family from the basic 8100 routers at 17.18.1. |
|
Mounting hardware |
Confirm which of rackmount, desktop, under-desk or DIN-rail mounting the site uses and that the accessory is on the order. |
Each mounting position needs its own hardware. |
