FAQs

Q: How many EHWIC slots remain after installing the SHDSL module?
A: The EHWIC‑4SHDSL‑EA is double‑wide and occupies both EHWIC slots on the 1921.

A: The module supports SHDSL.bis per ITU‑T G.991.2 with Annex A/E and EFM bonding per IEEE 802.3ah.

Q: Can this router also use LTE?
A: LTE is supported via compatible EHWIC cellular modules, but note the SHDSL double‑wide card uses both EHWIC slots; you would need to remove it to install a cellular module.

Q: Is SD-WAN supported?
A: Native SD-WAN is not supported on ISR G2 platforms.
