NM-HDV2-2T1/E1 Use Case
Service Provider Voice Trunk Aggregation with NM-HDV2-2T1/E1-IP Module
In a regional telecom network, a service provider deploys the NM-HDV2-2T1/E1-IP Communications High-Density Digital Voice NM with 2 T1/E1 Cisco Router Network Module on Cisco ASR routers to aggregate up to 120 simultaneous voice calls over T1/E1 trunks. By leveraging built-in transcoding and TDM-to-IP conversion, the provider seamlessly carries legacy PSTN traffic across its MPLS backbone. Outcome: 50% reduction in trunk port capital expenditures, 30% lower operational complexity, and improved SLA adherence through end-to-end QoS and voice packet prioritization.
Enterprise Contact Center PSTN Gateway Upgrade
A Fortune 500 financial services firm replaces aging analog gateways with the NM-HDV2-2T1/E1-IP Communications High-Density Digital Voice NM installed in their Cisco ISR routers. The module terminates multiple T1/E1 lines directly into the contact center’s SIP-based IVR and ACD platforms. Outcome: 40% cost savings on maintenance, 25% faster call setup times, and improved call quality metrics by leveraging built-in echo cancellation, voice buffering, and centralized session management.
Multi-Site Branch Office Unified Voice Migration
A manufacturing enterprise onboards 15 branch plants by deploying NM-HDV2-2T1/E1-IP Communications High-Density Digital Voice NM modules in Cisco ISR routers at each site. They replace disparate analog PBX trunks with standardized T1/E1 voice streams over a dedicated IP VPN. Outcome: Consolidated voice infrastructure driving a 20% drop in long-distance toll charges, simplified network operations through a single Cisco management plane, and accelerated deployment of new site rollouts by 50%.
