Maximun Data Rate 2048kbps
ITU 991.2 (2004) (G.SHDSL .Bis) supports data rate up to 5696Kbps, but G.703 (E1 standard) only supports data rate of
2048kbps so the maximum data rate of SHDSL line, connected with E1 DCEs, depends on data rate of E1, 2048kbps.

Data rate # of TS
If the connection is E1 vs V.35 or V.35 vs E1, the frame has to be used N x 64k. In this case, the data rate depends on
value of N. Same as above case, SHDSL and V35 can support up to 5696kbps data rate, but E1 supports maximum data
rate of 2048kbps (32 x 64k).

Frame N x 64 (N=1~31)
Time slots, N value, are placed in the frame. If time Slot Number is1 from 1~31 (N=1~31), it is Fractional E1. If time Slot
Number is 32 (N=32), it is unframed.
