Thank you, burakkucat, that is just what I was looking for. When entered on the TalkTalk-provided, Huawei HG523a, the following is returned:
system type : RTL8672
processor : 0
cpu model : R3000 V0.0
BogoMIPS : 398.95
wait instruction : no
microsecond timers : no
tlb_entries : 32
extra interrupt vector : no
hardware watchpoint : no
ASEs implemented :
VCED exceptions : not available
VCEI exceptions : not available
'Googling', RTL8672, shows that this router uses a Realtek chipset for its ADSL functions.
This seems to provide an excellent connection speed with the Infineon exchange equipment TalkTalk uses. In my case, this router syncs in excess of 500Kbps more than any other router I have tried thus far.
