HWIC-4T1/E1 Use Case
Enterprise Multi-Branch WAN Aggregation using Cisco HWIC-4T1/E1
In a global enterprise with 50 branch offices, network architects install the Cisco HWIC-4T1/E1 4-port clear-channel T1/E1 High-Speed WAN Interface Card in ISR routers to terminate and bond four T1/E1 circuits per site. Paired with OSPF/MPLS, this solution delivers up to 25 Mbps of dedicated bandwidth, per-VC QoS and DMVPN failover. The outcome: predictable, low-latency connectivity that meets 99.99% uptime SLAs, simplifies provisioning and reduces overall WAN costs by 20%.
Carrier-Grade VoIP Trunking for Cisco Unified Communications
A service provider implements the Cisco HWIC-4T1/E1 card in Cisco ISR platforms to terminate four PRI/E1 lines for Cisco Unified Communications Manager. The clear-channel T1/E1 links support up to 120 simultaneous VoIP sessions, ESS redundancy and granular dial-peer configuration. Built-in echo cancellation, precise channel allocation and per-port QoS ensure 99.9% voice clarity and seamless PSTN integration, cutting voice gateway CAPEX by 35%.
Managed T1/E1 Demarcation and SLA Delivery for Service Providers
Telecom operators deploy the Cisco HWIC-4T1/E1 in regional Points-of-Presence to provide managed point-to-point and point-to-multipoint T1/E1 services. Integrated with Cisco IOS Carrier Support, it offers CFM OAM, per-port SLA monitoring and dynamic bandwidth provisioning. This enables sub-2-second fault isolation, configurable CIR and hierarchical QoS for enterprise customers, accelerating time-to-market, strengthening SLAs and boosting recurring revenue by 15%.
