That was my mistake Mike. HDSL is NOT two SDSL lines by definition. It's
just two circuits running symmetric 768k DSL (not SDSL) bonded to form a
single1.5mb line.

My fault for using SDSL (where S is the initial for symmetric) instead of
symmetric DSL lines. They are two different things in this case.

Sorry for the confusion I started, please resume your regularly scheduled
nanog ranting. :)

And thanks for the nitpicking Mike. :)

John Tamplin:
the smartjack extracts the T1 -- I have two of these in my house, using
Pairgain (now ADC)'s HiGain Solitaire H2TU.R402 for T1 transport.  The
URL
of the frame describing the product line is at (minus any line breaks or
spaces added along the way):

http://www6.adc.com/ecom/wps?lineid=OND2737&group=T1%2bTransport%252FHiGain&;
EXPAND=OND50995&L=EC_List_Group_Index.html&R=WPS_Out_Hierarchy.html&ID=OND50
995
This specific card is under HDSL2 RT Modules.

Thats the units we have on the wall for some recent T1 installs as well.
So far working very well.. Yes, it is HDSL, It's not 2 x 786K sDSL or
whatever as stated in the original posted email that I responded to.

Whats funny is I got 2 private emails from BellSouth engineering types
that did not know they were being installed in this region.
