HDSL4 for E220, DDM+, 3192 H4TU-C for E220, DDM+, and 3192 Form Factors Product Features ■ Standards-based technology for industry-required interoperability ■ Spectral compatibility with ADSL ■ Improved operating margins in the CSA ■ DS1 payload over two copper pairs, with added coding gain, for reduced signaling bandwidth ■ Extended range T1 deployment for areas just beyond the CSA eliminating the need for repeaters ■ Industry-leading, warranty 10-year T1 line deployments remain a staple in service portfolios of most telecom carriers. However, numerous legacy T1 lines, relying on older Alternate Mark Inversion modulation techniques, have been replaced by HDSLx technology. ADTRAN® offers end-toend HDSL4 card solutions for the most frequently found legacy form factors in telecom networks — E220, DDM+, and 3192. Issue 2 of ANSI T1.418 standard for HDSL2 includes a 4-wire TC PAM T1 transport technology called HDSL4. This technology is a 4-wire (2-pair) implementation of the High Bit Rate Digital Subscriber Line - 2nd Generation (HDSL2) technology. HDSL4 combines two well-known approaches to DS1 transport, HDSL and HDSL2. HDSL4 provides a standards-based repeatered T1 transport technology that remains spectrally compatible with ADSL per ANSI T1.418. HDSL4 offers improved operating margins, a good price/performance value, and spectral compatibility with ADSL in the same binder group. It allows deployment ranges (without repeaters) beyond HDSL and HDSL2. Carriers can avoid replacement of costly repeaters in areas just beyond the CSA. In fact, HDSL4 is the only extended reach T1 transport technology that is spectrally compatible with ADSL (per ANSI T1.418) when deployed with repeaters. The ADTRAN HDSL4 solutions include central office, repeater, and remote cards for legacy form factors commonly found in networks. HDSL4 products provide span powering voltage (negative only with respect to ground, –190 VDC nominal, GFI protection less than 5 mA) and meets all requirements of Bellcore GR-1089-CORE (Class A2), ANSI T1. 418-2002. The products are NRTL listed to the applicable UL standards. ADTRAN’s HDSL4 repeaters feature inband loopback control, remote provisioning, and pass-through control. They are available in standard T200 and 239 mechanics. ADTRAN’s HDSL4 units are equipped with troubleshooting-at-a-glance LEDs that provide customers with a simple means of identifying the location of certain faults. Several new screens have been added to the craft interface to simplify the trouble isolation process. These HDSL4 units are equipped to support the ADTRAN TScanTM feature. TScan allows the remote retrieval of circuit diagnostics and performs advanced fault location. For implementation of TScan, please contact your local ADTRAN sales representative.
