Dear Treggers, Mel Pedersen of Midcom asks:
" Is there an ANSI HDSL specification? A customer of mine referenced ANSI T1E1.4/94-006 but I have not been able to find it. This specification would recommend such things as a pulse template, return loss, balance, etc. I have inquired at ANSI's web site, but to no avail." I have a copy of a Bellcore Technical Advisory dated October 1991: TA-NWT-001210 "Generic Requirements for High-Bit-Rate Subscriber Lines" (a module of TSGR, FR-NWT-000440). Undoubtedly, this document has been since revised. The document describes the physical signal characteristics, etc. The Bellcore document also refers to ANSI TI-601-1988, TI.403-1989 and TI.408-1990, which if I'm not mistaken are specifications for ISDN. Indeed, it seems to me that the physical interface is exactly the same as primary rate ISDN. Hope this helps.
