Sunrise Telecom SSMTT-19A ADSL2 ATU-R Module Card

Sunrise Telecom SSMTT-19A TI ADSL2+ ATU-R Module for SunSet MTT/xDSL test sets is a plug-in ATU-R module powered by TI AR7 TNETD7300A that lets technicians emulate a remote DSLAM and verify ADSL services in the field. The rugged, battery‑operated handheld unit is part of the SunSet MTT/xDSL family and integrates with SunSet MTT and SunSet xDSL host chassis for portable field testing. It supports ADSL technologies including ADSL2+ (ITU-T G.992.5), ADSL2 (ITU-T G.992.3), Reach Extended ADSL2 (Annex L), G.dmt ADSL/POTS with S=1/2 (ITU-T G.992.1 Annex A and ANSI T1.413), G.lite (ITU-T G.992.2), and ADSL2+ extended framing parameters (ITU G.992.5 Amendments 1 and 2). Key features include pass-through modem emulation, detailed modem/link status, and link measurements, plus network verification tools such as Trace Route and ATM OAM testing with automatic response to far-end F4/F45 OAM requests. For testing scope, the ATU-R module offers protocols supported: ICMP and UDP, up to 30 hops on the IP network, and a VCC scan for up to 8 active VPi/VCi, enabling comprehensive DSLAM-to-CPE validation. The design emphasizes a one-button turn‑up workflow to simplify service verification and deliver insight into downstream/upstream performance and line health, with path latency options in Fast or Interleaved modes.
