HWIC-4SHDSL Use Case
Resilient Multi-Branch WAN Connectivity with HWIC-4SHDSL-4-pair G.shdsl HWIC
A nationwide retail chain deploys Cisco ISR routers equipped with the HWIC-4SHDSL-4-pair G.shdsl HWIC with IMA support to aggregate four SHDSL lines at each of 50 branch outlets. By bonding individual 4 Mbps pairs into a single 16 Mbps symmetric WAN link, the solution delivers unified management, automatic load-balancing and active-standby redundancy. Outcome: 99.99% branch uptime, a 30% drop in monthly bandwidth charges and simplified end-to-end network operations.
High-Availability Metro Ethernet Backup Using HWIC-4SHDSL-4-pair G.shdsl HWIC
A financial services firm relies on Metro Ethernet for primary connectivity but needs rapid failover in case of outages. By installing the HWIC-4SHDSL-4-pair G.shdsl HWIC with IMA support in its Cisco routers, four independent SHDSL loops are bonded into a resilient 20 Mbps backup path. Benefit: sub-50 ms switchover, guaranteed SLA compliance and elimination of costly temporary fibre rentals during network maintenance windows.
Secure Remote SCADA Connectivity for Industrial IoT over SHDSL
An oil and gas operator connects 30 remote pump stations using Cisco routers fitted with the HWIC-4SHDSL-4-pair G.shdsl HWIC with IMA support. Aggregating four SHDSL links provides a 12 Mbps encrypted channel for real-time SCADA telemetry and VoIP voice monitoring. Benefit: deterministic symmetric bandwidth with AES VPN encryption, 40% lower TCO versus satellite backup and rapid deployment even in areas lacking fiber infrastructure.

Questions & Answers
Q
What is the Cisco HWIC-4SHDSL?
A
The Cisco HWIC-4SHDSL is a 4-pair G.shdsl High-Speed WAN Interface Card for Cisco ISR routers, delivering symmetrical data rates up to 15.3 Mbps per pair.
Q
What are the key features of the HWIC-4SHDSL?
A
Key features include four G.shdsl pairs, up to 61.2 Mbps aggregate throughput, Inverse Multiplexing for ATM (IMA) support, and an RJ-21 interface for multi-pair connectivity.
Q
Which Cisco routers support the HWIC-4SHDSL?
A
The HWIC-4SHDSL is supported on Cisco ISR G2 series routers, including models 1841, 2801, 2811, 2821, 2851, 2911, 2921, 2951, and later platforms with HWIC slots.
Q
What is G.shdsl and how does it work?
A
G.shdsl is a symmetrical DSL standard that uses advanced single-line modulation over copper pairs to deliver equal upstream and downstream rates up to 15.3 Mbps.
Q
What data rates does the HWIC-4SHDSL support?
A
Each G.shdsl pair supports from 192 kbps to 15.3 Mbps; all four pairs can be combined via IMA for up to 61.2 Mbps aggregate bandwidth.
Q
How does IMA support improve performance?
A
IMA (Inverse Multiplexing for ATM) aggregates multiple G.shdsl channels into a single logical link, boosting bandwidth and providing load-balanced redundancy across four pairs.
Q
How do I install the HWIC-4SHDSL in my router?
A
Power down the router, insert the HWIC-4SHDSL into an available HWIC slot, secure with the captive screws, reconnect power, then attach the RJ-21 cable and verify with Cisco IOS commands.
Q
What cable types are required for HWIC-4SHDSL connections?
A
Use a DB-78 to RJ-21 or RJ-11 multi-pair cable with 24 AWG or better solid copper conductors; maximum recommended distance per pair is up to 5 km, depending on line quality.
Q
How do I configure G.shdsl on Cisco IOS?
A
Enter interface configuration mode for the HWIC slot, set ‘encapsulation shdsl’, define the desired line rate with ‘shdsl rate’, enable IMA with ‘shdsl ima group’, and apply your IP or routed protocol settings.
Q
What is the maximum reach of G.shdsl lines on this module?
A
Maximum reach is approximately 5.5 km (18,000 ft) per pair at lower data rates, with distance decreasing as line rate increases.
Q
How do I troubleshoot HWIC-4SHDSL connectivity issues?
A
Use ‘show controllers shdsl detail’, verify signal-to-noise ratio and CRC counters, perform local loopback tests, and check physical cable continuity and pin assignments.
Q
Is the HWIC-4SHDSL compatible with all Cisco IOS releases?
A
The module requires Cisco IOS 12.4(20)T or later with the SHDSL feature set; later 15.x releases also provide full support and enhanced monitoring MIBs.
Q
What are the power requirements for the HWIC-4SHDSL?
A
The module draws up to 3.5 W from the router’s HWIC slot at 3.3 V and is designed to operate within standard Cisco ISR G2 power specifications.
Q
Can I use the HWIC-4SHDSL in a high-availability setup?
A
Yes; you can deploy redundant routers running HSRP or VRRP with IMA channel groups mirrored across devices for sub-second failover.
Q
Where can I purchase the Cisco HWIC-4SHDSL and what warranty applies?
A
The HWIC-4SHDSL is available through authorized Cisco resellers and distributors; it includes a one-year limited hardware warranty, extendable with Cisco SMARTnet support.
Q
How can I monitor HWIC-4SHDSL performance remotely?
A
Monitor performance locally via ‘show controllers shdsl’ and remotely using SNMP with the CISCO-IF-EXT-MIB for line statistics, error rates, and bandwidth utilization.
Q
Does the HWIC-4SHDSL support protection switching?
A
Yes; with IMA it supports 1+1 protection switching, ensuring continuous operation by automatically rerouting traffic if a G.shdsl channel fails.
