NM-HDV2-1T1/E1 Use Case
Legacy T1/E1 Voice Migration for Remote Branch Offices
A nationwide retail chain operating dozens of remote stores replaces standalone T1/E1 voice routers with Cisco ISR 4000 series equipped with the NM-HDV2-1T1/E1-IP High-Density Digital Voice Network Module. The module consolidates up to 24 T1/E1 voice channels into IP, enabling unified voice/data transport over a single MPLS link. Benefit: reduces site equipment footprint by 50%, cuts monthly WAN costs by 30%, and accelerates feature rollout via centralized Cisco DNA Center management.
Service Provider Central Office Voice Aggregation
A tier-2 telecom provider deploys the Cisco NM-HDV2-1T1/E1-IP High-Density Digital Voice NM on ASR 1000 routers in its central office to aggregate hundreds of legacy T1/E1 circuits into an IP backhaul cloud. Advanced DSP resources handle G.711/G.729 transcoding, echo cancellation, and CAS/PRI signaling in hardware. Benefit: achieves 40% higher port density per rack unit, accelerates new revenue streams with on-demand voice trunk provisioning, and delivers carrier-grade MOS >4.0 voice quality.
Carrier-Grade Voice Failover and Resiliency
A multinational bank implements dual Cisco 4000 series routers with NM-HDV2-1T1/E1-IP High-Density Digital Voice Network Modules at each data center for its mission-critical trading floors. Leveraging Cisco HSRP and VRRP, active T1/E1 voice sessions seamlessly fail over to backup links upon link degradation. Benefit: ensures 99.999% voice uptime for compliance with financial SLAs, eliminates revenue impact from downtime, and maintains seamless trader communication under any network condition.
