Arris's Touchstone Telephony Modem TM502G
The Touchstone TM502G delivers two lines of primary line Voice over IP (VoIP) along with High-Speed Data Access. The Touchstone Telephony Modem TM502G uses a single battery slot with two battery pack options to support telephony service during extended power outages.
The Touchstone TM502G continues the ARRIS strategy of a single firmware platform for all Touchstone Telephony Modem models. This ensures consistent quality and performance of all Touchstone Telephony Modems. Do not put your trust in reference designs that cannot deliver the performance and requirements for your telephony service. When it comes to high-speed data service, subscribers will accept occasional lock-ups or momentary loss of connectivity that may require them to reboot their cable modem. This behavior is not acceptable for telephony. Telephony customers demand 99.999% availability. All ARRIS Touchstone Telephony Modems support a wide variety of class features including three-way calling, call waiting, caller ID, Emergency 911 and regulatory requirements for wiretap under CALEA legislation.
