Description

EFM-based SHDSL.bis HWIC delivering symmetric Ethernet services over 1–4 bonded copper pairs. Ideal for last‑mile business access where fiber is unavailable, with IEEE 802.3ah EFM bonding for aggregate throughput and resilience.

Features

- Symmetric Ethernet services over existing copper
- EFM bonding across up to four pairs for higher aggregate bandwidth
- Standards-based interoperability with G.991.2 and IEEE 802.3ah
- Cost-effective fiber alternative for business access
- ISR router integration for QoS, VPN, and advanced routing

FAQs

Q: Do I need an SHDSL DSLAM for this module?
A: Yes. It terminates to an SHDSL.bis DSLAM/MSAN that supports IEEE 802.3ah EFM mode.

Q: Can multiple copper pairs be bonded?
A: Yes, up to four pairs can be bonded using EFM to increase throughput and resilience.

Q: What throughput can I expect?
A: Throughput depends on loop length and copper quality. Multi-pair bonding typically provides significantly higher symmetric rates than single-pair.

Q: Is a splitter required?
A: Typically an SHDSL POTS/ISDN splitter is not required since SHDSL uses separate spectrum, but follow your provider’s plant and CPE guidelines.
