Full Unbundling –
Metallic Path Facility (MPF)
Under full MPF, the whole line is transferred from
Openreach to communications providers so they
can provide their broadband and/or voice services
direct to end users.
The communications provider’s network is
connected to the Main Distribution Frame
(MDF) in a BT exchange via a tie cable. The LLU
communications providers then take responsibility
for running their customers’ services over the
local loop.
- Physical co-location: where communications providers choose to install their network equipment in a BT exchange
- Distant location: where communications providers decide to locate off-site, but close to a BT exchange
Under full unbundling, communications providers
have total responsibility for the relationship with
their customer, while Openreach provides
maintenance for the local loop and responds to
fault reports.
Shared Line –
Shared Metallic Path Facility (SMPF)
Under SMPF, communications providers share a
line between the local telephone exchange and
their end user’s premises in order to supply
broadband. Telephony services, supplied by a
wholesale line rental communications provider
(WLR CP) use the same line.
SMPF is made possible by installing ‘splitters’
in the end user’s home/office and the
communications provider’s network equipment.
Under line sharing, the end user has contracts with
both the narrowband provider (WLR CP) and the
LLU communications provider.
