About the Cisco NM-HDV2-2T1 Cisco network interface module
The Cisco NM-HDV2-2T1 is a high-density voice network module engineered for hot-swap installation into Cisco router backplanes, delivering enterprise-grade telecommunications connectivity without requiring external power. This Network Module (NM) form factor integrates seamlessly into compatible Cisco platforms, enabling rapid deployment and field upgrades in production environments.
The NM-HDV2-2T1 delivers two T1 WAN ports with 24 DS0 channels per port, yielding 48 total DS0 channels for consolidated voice traffic management. Built on Cisco's HDV2 (High-Density Voice, second generation) DSP architecture, the module supports multiple voice codecs including G.711 (a-law and μ-law), G.726, G.728, and G.729a/b variants, alongside dual signaling protocols—PRI (ISDN) and CAS (Channel Associated Signaling)—for flexible telecom integration. VoIP protocol support spans H.323, SIP, and MGCP, ensuring compatibility with diverse enterprise voice infrastructures. The module complies with T1/D4 standards (ESF/SF framing) and supports both B8ZS and AMI line coding, with an operating temperature range of 0°C to 40°C and storage tolerance from -40°C to 70°C. As a genuine Cisco OEM component, the NM-HDV2-2T1 carries full Cisco TAC Support validation for case verification and troubleshooting.
Network engineers and IT procurement teams responsible for unified communications infrastructure standardize on this module when consolidating legacy T1 voice circuits and modern VoIP services within existing Cisco router estates. Compatible with Cisco 2600XM, 2691, 2800 series, 3660, and 3700 series routers, deployment requires only the appropriate Cisco IOS release featuring IP Voice or Advanced IP Services feature sets.
