Abstract: An access network includes a twisted metallic pair connection over which data may be transmitted in accordance with a digital subscriber line protocol of transmission. The access network further includes an access network modem connected to the twisted metallic pair connection which is operable to transmit and receive signals thereover, in accordance with a digital subscriber line protocol of transmission. The access network further comprises a broadband speed estimation tool including a web server and/or an order processing sub-system 1120 and a line length, further deployment factors and speed determiner module 1170. The access network further comprises a line management subsystem which determines an appropriate value for each of one or more configuration parameters associated with the operation of the access network modem in dependence upon an estimated data rate and causes the access network modem to operate in accordance with the determined value or values of the configuration parameters.

Abstract: This invention relates to an optical cable, in particular to an optical fibre having an axially extending glass strand for channelling light therealong, and a jacket layer disposed around the glass strand, the jacket layer having a textured outer surface for facilitating, under the influence of a fluid drag, the advancement of the optical cable along a conduit, wherein the glass strand in cross section to the axial direction has a width of less than 100 microns. The reduced width of the glass strand(s) in the cable will cause the cable to be less stiff, which will be particularly beneficially when installing the cable using a blowing technique.

Abstract: A sub-ducting apparatus comprising a sub-duct, and a remotely operable path-finding head for facilitation of the subduct into a duct. The head is detachable at the end of the subduct and includes an expandable portion or a cutter, as a result of which, twisted or jammed cables may be removed from the duct.
