New KEYMILE card for VDSL2 services enhanced with vectoring
Hanover, 15 October 2013 – KEYMILE presents a new card for multi-service access platform MileGate. It combines 96 VDSL2 via ISDN ports with vectoring functions on one card. As a result, data rates of over 100 Mbps per subscriber can also be provided in mass rollouts.
KEYMILE is a leading technology supplier of communications solutions for access and transmission systems. It has now announced a new VDSL2/vectoring card. This card is intended for European telecommunications suppliers that offer ISDN services. It supports VDSL2 in line with ITU-T G.993.2 (a version for VDSL2 via POTS is already available). The VDSL2/vectoring card permits services such as broadband Internet, video-on-demand, HD IPTV and VoIP via VDSL2 with ISDN telephony. Network operators can also apply the board to offer ADSL2plus and VDSL2 services using just one card.
Via the ITU-T-G.993.5 procedure, the board’s on-board vectoring unit identifies cross-talk between the VDSL2 signals on the transmission paths. The card corrects all VDSL2 signals in real time, therefore compensating for the negative FEXT (Far End Crosstalk) effect. In order to achieve the best results, all VDSL2 signals in a cable must be included in the vectoring process. As a result, the card uses the system-level-vectoring approach. Two cards can be connected with one another and therefore provide up to 192 VDSL2 ports enhanced with vectoring. Even when all subscribers have VDSL2 connections, system-level vectoring reliably provides data rates of more than 100 Mbps downstream and over 40 Mbps upstream to each customer.
Therefore, a fully equipped MileGate 2510 provides up to 960 VDSL2 lines with vectoring added. If lower subscriber density is required, network operators can connect up to 288 or 96 subscribers with MileGate 2310 or the mini DSLAM subrack MileGate 2200 respectively.
Furthermore, the board offers a MELT line test. This metallic line test allows network operators to qualify the service line from the exchange, to identify external voltage, resistance and capacities and to spot the type of malfunction should a fault occur. On-site inspections are no longer necessary.
The new VDSL2 board is ideal for outdoor cabinets and therefore for creating FTTC network architecture. Initial deliveries will be made at the end of 2013.
