At present, the standard configuration for 64 x ADSL and 64 x POTS units are not
provided with protection units. This is as specified by the Customer.
From the COMBI cards, 64-pair cables run via Overhead Runways to 100-pair IDC
strips located on the Handover Distribution Frame (HDF).
From the 32 x TAM Connection Unit, 32-pair cables run via Overhead Runways to
100-pair IDC strips located on the Handover Distribution Frame (HDF).
From the HDF blocks, 100-pr cable runs to the BT MDF. HDF blocks and HDF-to-
MDF cabling are provided by BT
HANDIN cabling (from HDF blocks designated LLUT or LLUX) allows connection to
C&W subscribers via the BT ‘last mile’ copper connection. Broadband traffic is
aggregated in the EDA 2530 & routed to the C&W Network via Backhaul fibre from
the Common Part board.
HANDBACK cabling (from HDF blocks designated LLUL) routes POTS telephony
traffic back to the BT Network.
For a pair with a POTS/VoIP card, telephony traffic is routed to the C&W
Network via Backhaul and thus HANDBACK cabling is NOT required.
Where a new EDA2530 Subrack is fitted on a site with an existing EDA2510
Subrack, the new Subrack will become the PARENT & the EDA2510 will become
the CHILD: the existing Backhaul fibre will be re-directed to the EDA2530 & a new
EDA-to-EDA fibre link provided. The EDA2510 will then sub-tend from the
EDA2530.
