There was a thread on UKNOF on the modem withdrawl back in Sept too,
where Neil said he might come back with some further info, but I don't
think I've seen any since unless I missed it. I think the consensus was
that it'd be nice if the Openreach modem could continue to be offered as
an order option.

Hello,
BT stocks of FTTC VDSL2 modems are already scarce in some BT Openreach
engineering circles and we have had recent installs where the
engineers have not supplied a modem, despite their contract to supply
with new installs until 'March' and then support till 2017.
Please excuse the below as it is may be more suited to Cisco-NSP (we
utilise Cisco CPE for our CE devices);
This appears to have thrown up an interesting problem in so far that
turning to integrated devices such as the Cisco 887VA-M or Cisco 897
which are "approved and certified for use with BT GEA/FTTC and
compliant with SIN498", do not appear to support q-in-q across the
VDSL ethernet interface.
The configuration examples I have reviewed and limited testing carried
out thus far show VLAN 101 tagged on the VDSL ethernet interface as
per the BT SIN requirement but there is an inability to tunnel
additional VLANS across this interface/VLAN cleanly, which is a
requirement for the service we provide.
I have raised the issue with Cisco to see if there is a work around or
something obvious with regards to configuration that I am missing but
this has not turned up anything positive so far.
In the event that Cisco CPE cannot meet our requirements (without
having to resort to hacky work arounds) I am also investigating
obtaining a supply of VDSL2 modems but this is also proving
challenging with ECI quoting a high minimum order quantity and Huawei
unable to supply due to the Echolife HG612 being 'EOL'.
Anyone out there trunking multiple VLANs to a CE over FTTC, in a
similar position?
Thanks.
