EhubAmerica TM602A DOCSIS 2.0 Cable Modem VoIP 42 Mbps

The ARRIS Touchstone TM602A is a DOCSIS 2.0-compliant Embedded Multimedia Terminal Adapter (E-MTA) engineered for service-provider deployment, delivering simultaneous high-speed data and carrier-grade Voice over IP over a single coaxial cable connection. Supporting two independent VoIP lines via PacketCable NCS and SIP protocols alongside 10/100 Base-T Ethernet and USB 1.1 data interfaces, it addresses the converged broadband and telephony infrastructure demands of modern cable plant operations. A 1 GHz tuner extends plant compatibility into future network upgrades, while configurable battery management—including boot-from-battery capability—ensures telephony continuity during power interruptions. Telcordia GR-1089 lightning and surge compliance, loop diagnostics for remote wiring verification, and support for multiple country telephony templates make the TM602A a disciplined choice for carriers and managed service environments requiring reliability, serviceability, and standards conformance.

Key features & benefits

• DOCSIS 2.0 and EuroDOCSIS 2.0 Compliance — Fully compliant with DOCSIS 2.0 and EuroDOCSIS 2.0 standards while maintaining backward compatibility with DOCSIS 1.0 and 1.1, protecting existing cable plant investments and simplifying multi-generation network management.
• Dual Carrier-Grade VoIP Lines — Supports two simultaneous lines of carrier-grade Voice over IP using both PacketCable NCS and Session Initiation Protocol (SIP), providing deployment flexibility across diverse service-provider voice architectures.
• 1 GHz RF Tuner — Equipped with a 1 GHz downstream tuner covering 88–1002 MHz, positioning the unit for compatibility with future cable plant frequency expansions without hardware replacement.
• High-Performance RF Downstream — Downstream RF supports 64-QAM and 256-QAM modulation across a 6 MHz channel bandwidth, delivering data rates up to 30 or 42 Mbps with an input sensitivity range of -15 to +15 dBmV.
• Flexible RF Upstream with Wide Modulation Support — Upstream RF operates from 5–42 MHz with support for QPSK through 128-QAM (S-CDMA), automatic level adjustment, 50 dB gain control range, and output impedance of 75 Ohms for precise plant optimization.
• Configurable Battery Backup with Boot-from-Battery — Supports a 2-cell Li-Ion battery for up to 8-hour standby or an 8-cell pack for up to 24-hour standby, with firmware-configurable management parameters and the ability to boot entirely from battery without AC power present.
• Robust Telephony Line Card — Delivers 48 VDC supervisory voltage, up to 10 REN total ringing load (5 per line), a maximum loop length of 1,000 ft of 26 AWG wire, and high loop current mode at 40 mA constant current, representing over 20% improvement in high loop current and 10% greater ringing voltage versus the TM502.
• Loop Diagnostics and Remote Troubleshooting — Integrated loop diagnostics enable remote testing and fault isolation of in-premises wiring, reducing truck-roll frequency and accelerating service restoration for support teams.
• Dual Data Interfaces — Provides both a 10/100 Base-T Ethernet port (RJ-45) and a USB 1.1 Series B port for customer premises equipment connectivity, accommodating varied CPE deployment scenarios.
• Telcordia GR-1089 Surge Compliance — Tested and compliant with Telcordia GR-1089 lightning and power surge standards, meeting carrier-grade durability requirements for telephony equipment installed at subscriber locations.
