Excellent half-slot density. Four channelized T3 ports in such a small space is a great way to maximize our chassis usage. Very reliable.
Steady and fast. It handles our channelized T3 traffic perfectly, providing reliable circuits for our regional branches. Solid build quality.
Highly efficient line card. The performance on each port is consistent and the setup was very straightforward for our team.
Great throughput for channelized circuits. It's been a reliable part of our TDM network, offering high uptime and low maintenance.
Sophisticated engineering in a small form factor. It delivers the granular T3 control we need without wasting valuable slot space.
Precise and dependable. This half-slot card provides the perfect balance of port density and high-speed performance for our T3 links.
The ESR-HH-4CT3 is a half-slot network interface card providing four channelized DS3/T3 ports for high-density telecom and data applications.
The ESR-HH-4CT3 supports four independent channelized T3 (DS3) ports, each carrying up to 44.736 Mbps of full-duplex bandwidth.
Channelized T3 on the ESR-HH-4CT3 splits each 44.736 Mbps DS3 link into 28 DS1 (E1) or 84 DS0 channels, enabling granular voice and data transport.
The ESR-HH-4CT3 is compatible with any half-slot ESR or third-party carrier-grade chassis that supports standard PCIe-based line cards.
Each T3 port on the ESR-HH-4CT3 uses an industry-standard RJ48C connector for straightforward integration with existing T3 cabling.
Yes. The ESR-HH-4CT3 is fully hot-swappable, allowing insertion or removal without powering down the host chassis.
The line card supports SNMP v1/v2c for out-of-band management and includes CLI and web-based GUIs via the host chassis controller.
Each port delivers up to 44.736 Mbps full-duplex, totaling 178.944 Mbps aggregate throughput across all four ports.
Yes. It offers full DS3 alarm reporting (AIS, LOS, LOF) and real-time performance metrics compliant with ITU-T O.191 standards.
Typical use cases include voice trunking, private line services, DS3-to-DS1 grooming, and multi-tenant broadband aggregation.
Operating temperature: 0 °C to 50 °C; humidity: 5%–95% non-condensing; complies with RoHS and NEBS Level 3 requirements.
Power down the chassis, insert the card into an available half-slot slot, secure with the captive screws, then power up and configure via the chassis management interface.
The line card draws approximately 8 W at full load, with intelligent power management to minimize consumption when idle.
The ESR-HH-4CT3 includes a standard one-year limited hardware warranty and 24/7 technical support with optional extended coverage.
Yes. It fully complies with ANSI T1.102 and ITU-T G.703/G.704 standards for seamless interoperability with third-party T3 network devices.
