DSL Specifications
Tables 8 through 11 list the DSL feature specifications and DSLAM interoperability support for the Cisco 860VAE
Series Routers. For more information and details about DSLAM and line-card interoperability, please refer to the
following document: What Is Cisco ISR and ISR G2 xDSL Interoperability?
The Cisco 860VAE Series interoperability should be on par with the Cisco 880VA Series ISRs.
Table 8. DSL Feature Specifications
Multimode DSL (VDSL2 and
ADSL2 and 2+)
● Broadcom chipset
● Dying gasp
● IEEE 802.1q VLAN tagging
VDSL2:
● ITU G.993.2 (VDSL2)
● 997 and 998 band plans
● VDSL2 profiles: 8a, 8b, 8c, 8d, 12a, 12b, and 17a
● U0 band support (25–276 kHz)
● Ethernet PTM mode only based on IEEE 802.3ah 64/65 octet encapsulation
● DELT diagnostics mode
ADSL2/2+:
● ADSL over basic telephone service with Annex A and ISDN Annex B ITU G. 992.1 (ADSL), G.992.3
(ADSL2), and G.992.5 (ADSL2+)
● ADSL2+ over basic telephone service Annex M (for extended upstream bandwidth) for G.992.3 (ADSL2)
and G.992.5 (ADSL2+)
Note: Annex M performance is not optimal over Annex A SKUs.
● G.994.1 ITU G.hs Handshake Protocol
● Reach-extended ADSL2 (G.922.3) Annex L for increased performance on loop lengths greater than
16,000 feet from central office
● T1.413 ANSI ADSL DMT issue 2
● DSL Forum TR-067 and TR-100 performance compliant
● Inpulse Noise Protection (INP) with Extended Framing Parameters
● Downstream Power Back Off (DPBO)
